This is to address an issue in which `m.presence` results on initial sync are not returning entries of users who are currently offline. The original behaviour was from https://github.com/element-hq/synapse/issues/1535 This change is useful for applications that use the presence system for tracking user profile information/updates (e.g. https://github.com/element-hq/synapse/pull/16992 or for profile status messages). This is gated behind a new configuration option to avoid performance impact for applications that don't need this, as a pragmatic solution for now.

# Configuring Synapse
|
|
|
|
This is intended as a guide to the Synapse configuration. The behavior of a Synapse instance can be modified
|
|
through the many configuration settings documented here — each config option is explained,
|
|
including what the default is, how to change the default and what sort of behaviour the setting governs.
|
|
Also included is an example configuration for each setting. If you don't want to spend a lot of time
|
|
thinking about options, the config as generated sets sensible defaults for all values. Do note however that the
|
|
database defaults to SQLite, which is not recommended for production usage. You can read more on this subject
|
|
[here](../../setup/installation.md#using-postgresql).
|
|
|
|
## Config Conventions
|
|
|
|
Configuration options that take a time period can be set using a number
|
|
followed by a letter. Letters have the following meanings:
|
|
|
|
* `s` = second
|
|
* `m` = minute
|
|
* `h` = hour
|
|
* `d` = day
|
|
* `w` = week
|
|
* `y` = year
|
|
|
|
For example, setting `redaction_retention_period: 5m` would remove redacted
|
|
messages from the database after 5 minutes, rather than 5 months.
|
|
|
|
In addition, configuration options referring to size use the following suffixes:
|
|
|
|
* `K` = KiB, or 1024 bytes
|
|
* `M` = MiB, or 1,048,576 bytes
|
|
* `G` = GiB, or 1,073,741,824 bytes
|
|
* `T` = TiB, or 1,099,511,627,776 bytes
|
|
|
|
For example, setting `max_avatar_size: 10M` means that Synapse will not accept files larger than 10,485,760 bytes
|
|
for a user avatar.
|
|
|
|
## Config Validation
|
|
|
|
The configuration file can be validated with the following command:
|
|
```bash
|
|
python -m synapse.config read <config key to print> -c <path to config>
|
|
```
|
|
|
|
To validate the entire file, omit `read <config key to print>`:
|
|
```bash
|
|
python -m synapse.config -c <path to config>
|
|
```
|
|
|
|
To see how to set other options, check the help reference:
|
|
```bash
|
|
python -m synapse.config --help
|
|
```
|
|
|
|
### YAML
|
|
The configuration file is a [YAML](https://yaml.org/) file, which means that certain syntax rules
|
|
apply if you want your config file to be read properly. A few helpful things to know:
|
|
* `#` before any option in the config will comment out that setting and either a default (if available) will
|
|
be applied or Synapse will ignore the setting. Thus, in example #1 below, the setting will be read and
|
|
applied, but in example #2 the setting will not be read and a default will be applied.
|
|
|
|
Example #1:
|
|
```yaml
|
|
pid_file: DATADIR/homeserver.pid
|
|
```
|
|
Example #2:
|
|
```yaml
|
|
#pid_file: DATADIR/homeserver.pid
|
|
```
|
|
* Indentation matters! The indentation before a setting
|
|
will determine whether a given setting is read as part of another
|
|
setting, or considered on its own. Thus, in example #1, the `enabled` setting
|
|
is read as a sub-option of the `presence` setting, and will be properly applied.
|
|
|
|
However, the lack of indentation before the `enabled` setting in example #2 means
|
|
that when reading the config, Synapse will consider both `presence` and `enabled` as
|
|
different settings. In this case, `presence` has no value, and thus a default applied, and `enabled`
|
|
is an option that Synapse doesn't recognize and thus ignores.
|
|
|
|
Example #1:
|
|
```yaml
|
|
presence:
|
|
enabled: false
|
|
```
|
|
Example #2:
|
|
```yaml
|
|
presence:
|
|
enabled: false
|
|
```
|
|
In this manual, all top-level settings (ones with no indentation) are identified
|
|
at the beginning of their section (i.e. "### `example_setting`") and
|
|
the sub-options, if any, are identified and listed in the body of the section.
|
|
In addition, each setting has an example of its usage, with the proper indentation
|
|
shown.
|
|
|
|
## Modules
|
|
|
|
Server admins can expand Synapse's functionality with external modules.
|
|
|
|
See [here](../../modules/index.md) for more
|
|
documentation on how to configure or create custom modules for Synapse.
|
|
|
|
|
|
---
|
|
### `modules`
|
|
|
|
Use the `module` sub-option to add modules under this option to extend functionality.
|
|
The `module` setting then has a sub-option, `config`, which can be used to define some configuration
|
|
for the `module`.
|
|
|
|
Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
modules:
|
|
- module: my_super_module.MySuperClass
|
|
config:
|
|
do_thing: true
|
|
- module: my_other_super_module.SomeClass
|
|
config: {}
|
|
```
|
|
---
|
|
## Server
|
|
|
|
Define your homeserver name and other base options.
|
|
|
|
---
|
|
### `server_name`
|
|
|
|
This sets the public-facing domain of the server.
|
|
|
|
The `server_name` name will appear at the end of usernames and room addresses
|
|
created on your server. For example if the `server_name` was example.com,
|
|
usernames on your server would be in the format `@user:example.com`
|
|
|
|
In most cases you should avoid using a matrix specific subdomain such as
|
|
matrix.example.com or synapse.example.com as the `server_name` for the same
|
|
reasons you wouldn't use user@email.example.com as your email address.
|
|
See [here](../../delegate.md)
|
|
for information on how to host Synapse on a subdomain while preserving
|
|
a clean `server_name`.
|
|
|
|
The `server_name` cannot be changed later so it is important to
|
|
configure this correctly before you start Synapse. It should be all
|
|
lowercase and may contain an explicit port.
|
|
|
|
There is no default for this option.
|
|
|
|
Example configuration #1:
|
|
```yaml
|
|
server_name: matrix.org
|
|
```
|
|
Example configuration #2:
|
|
```yaml
|
|
server_name: localhost:8080
|
|
```
|
|
---
|
|
### `pid_file`
|
|
|
|
When running Synapse as a daemon, the file to store the pid in. Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
pid_file: DATADIR/homeserver.pid
|
|
```
|
|
---
|
|
### `web_client_location`
|
|
|
|
The absolute URL to the web client which `/` will redirect to. Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
web_client_location: https://riot.example.com/
|
|
```
|
|
---
|
|
### `public_baseurl`
|
|
|
|
The public-facing base URL that clients use to access this Homeserver (not
|
|
including _matrix/...). This is the same URL a user might enter into the
|
|
'Custom Homeserver URL' field on their client. If you use Synapse with a
|
|
reverse proxy, this should be the URL to reach Synapse via the proxy.
|
|
Otherwise, it should be the URL to reach Synapse's client HTTP listener (see
|
|
['listeners'](#listeners) below).
|
|
|
|
Defaults to `https://<server_name>/`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
public_baseurl: https://example.com/
|
|
```
|
|
---
|
|
### `serve_server_wellknown`
|
|
|
|
By default, other servers will try to reach our server on port 8448, which can
|
|
be inconvenient in some environments.
|
|
|
|
Provided `https://<server_name>/` on port 443 is routed to Synapse, this
|
|
option configures Synapse to serve a file at `https://<server_name>/.well-known/matrix/server`.
|
|
This will tell other servers to send traffic to port 443 instead.
|
|
|
|
This option currently defaults to false.
|
|
|
|
See [Delegation of incoming federation traffic](../../delegate.md) for more
|
|
information.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
serve_server_wellknown: true
|
|
```
|
|
---
|
|
### `extra_well_known_client_content `
|
|
|
|
This option allows server runners to add arbitrary key-value pairs to the [client-facing `.well-known` response](https://spec.matrix.org/latest/client-server-api/#well-known-uri).
|
|
Note that the `public_baseurl` config option must be provided for Synapse to serve a response to `/.well-known/matrix/client` at all.
|
|
|
|
If this option is provided, it parses the given yaml to json and
|
|
serves it on `/.well-known/matrix/client` endpoint
|
|
alongside the standard properties.
|
|
|
|
*Added in Synapse 1.62.0.*
|
|
|
|
Example configuration:
|
|
```yaml
|
|
extra_well_known_client_content :
|
|
option1: value1
|
|
option2: value2
|
|
```
|
|
---
|
|
### `soft_file_limit`
|
|
|
|
Set the soft limit on the number of file descriptors synapse can use.
|
|
Zero is used to indicate synapse should set the soft limit to the hard limit.
|
|
Defaults to 0.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
soft_file_limit: 3
|
|
```
|
|
---
|
|
### `presence`
|
|
|
|
Presence tracking allows users to see the state (e.g online/offline)
|
|
of other local and remote users. Set the `enabled` sub-option to false to
|
|
disable presence tracking on this homeserver. Defaults to true.
|
|
This option replaces the previous top-level 'use_presence' option.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
presence:
|
|
enabled: false
|
|
include_offline_users_on_sync: false
|
|
```
|
|
|
|
`enabled` can also be set to a special value of "untracked" which ignores updates
|
|
received via clients and federation, while still accepting updates from the
|
|
[module API](../../modules/index.md).
|
|
|
|
*The "untracked" option was added in Synapse 1.96.0.*
|
|
|
|
When clients perform an initial or `full_state` sync, presence results for offline users are
|
|
not included by default. Setting `include_offline_users_on_sync` to `true` will always include
|
|
offline users in the results. Defaults to false.
|
|
|
|
---
|
|
### `require_auth_for_profile_requests`
|
|
|
|
Whether to require authentication to retrieve profile data (avatars, display names) of other
|
|
users through the client API. Defaults to false. Note that profile data is also available
|
|
via the federation API, unless `allow_profile_lookup_over_federation` is set to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
require_auth_for_profile_requests: true
|
|
```
|
|
---
|
|
### `limit_profile_requests_to_users_who_share_rooms`
|
|
|
|
Use this option to require a user to share a room with another user in order
|
|
to retrieve their profile information. Only checked on Client-Server
|
|
requests. Profile requests from other servers should be checked by the
|
|
requesting server. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
limit_profile_requests_to_users_who_share_rooms: true
|
|
```
|
|
---
|
|
### `include_profile_data_on_invite`
|
|
|
|
Use this option to prevent a user's profile data from being retrieved and
|
|
displayed in a room until they have joined it. By default, a user's
|
|
profile data is included in an invite event, regardless of the values
|
|
of the above two settings, and whether or not the users share a server.
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
include_profile_data_on_invite: false
|
|
```
|
|
---
|
|
### `allow_public_rooms_without_auth`
|
|
|
|
If set to true, removes the need for authentication to access the server's
|
|
public rooms directory through the client API, meaning that anyone can
|
|
query the room directory. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_public_rooms_without_auth: true
|
|
```
|
|
---
|
|
### `allow_public_rooms_over_federation`
|
|
|
|
If set to true, allows any other homeserver to fetch the server's public
|
|
rooms directory via federation. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_public_rooms_over_federation: true
|
|
```
|
|
---
|
|
### `default_room_version`
|
|
|
|
The default room version for newly created rooms on this server.
|
|
|
|
Known room versions are listed [here](https://spec.matrix.org/latest/rooms/#complete-list-of-room-versions)
|
|
|
|
For example, for room version 1, `default_room_version` should be set
|
|
to "1".
|
|
|
|
Currently defaults to ["10"](https://spec.matrix.org/v1.5/rooms/v10/).
|
|
|
|
_Changed in Synapse 1.76:_ the default version room version was increased from [9](https://spec.matrix.org/v1.5/rooms/v9/) to [10](https://spec.matrix.org/v1.5/rooms/v10/).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
default_room_version: "8"
|
|
```
|
|
---
|
|
### `gc_thresholds`
|
|
|
|
The garbage collection threshold parameters to pass to `gc.set_threshold`, if defined.
|
|
Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
gc_thresholds: [700, 10, 10]
|
|
```
|
|
---
|
|
### `gc_min_interval`
|
|
|
|
The minimum time in seconds between each GC for a generation, regardless of
|
|
the GC thresholds. This ensures that we don't do GC too frequently. A value of `[1s, 10s, 30s]`
|
|
indicates that a second must pass between consecutive generation 0 GCs, etc.
|
|
|
|
Defaults to `[1s, 10s, 30s]`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
gc_min_interval: [0.5s, 30s, 1m]
|
|
```
|
|
---
|
|
### `filter_timeline_limit`
|
|
|
|
Set the limit on the returned events in the timeline in the get
|
|
and sync operations. Defaults to 100. A value of -1 means no upper limit.
|
|
|
|
|
|
Example configuration:
|
|
```yaml
|
|
filter_timeline_limit: 5000
|
|
```
|
|
---
|
|
### `block_non_admin_invites`
|
|
|
|
Whether room invites to users on this server should be blocked
|
|
(except those sent by local server admins). Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
block_non_admin_invites: true
|
|
```
|
|
---
|
|
### `enable_search`
|
|
|
|
If set to false, new messages will not be indexed for searching and users
|
|
will receive errors when searching for messages. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_search: false
|
|
```
|
|
---
|
|
### `ip_range_blacklist`
|
|
|
|
This option prevents outgoing requests from being sent to the specified blacklisted IP address
|
|
CIDR ranges. If this option is not specified then it defaults to private IP
|
|
address ranges (see the example below).
|
|
|
|
The blacklist applies to the outbound requests for federation, identity servers,
|
|
push servers, and for checking key validity for third-party invite events.
|
|
|
|
(0.0.0.0 and :: are always blacklisted, whether or not they are explicitly
|
|
listed here, since they correspond to unroutable addresses.)
|
|
|
|
This option replaces `federation_ip_range_blacklist` in Synapse v1.25.0.
|
|
|
|
Note: The value is ignored when an HTTP proxy is in use.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
ip_range_blacklist:
|
|
- '127.0.0.0/8'
|
|
- '10.0.0.0/8'
|
|
- '172.16.0.0/12'
|
|
- '192.168.0.0/16'
|
|
- '100.64.0.0/10'
|
|
- '192.0.0.0/24'
|
|
- '169.254.0.0/16'
|
|
- '192.88.99.0/24'
|
|
- '198.18.0.0/15'
|
|
- '192.0.2.0/24'
|
|
- '198.51.100.0/24'
|
|
- '203.0.113.0/24'
|
|
- '224.0.0.0/4'
|
|
- '::1/128'
|
|
- 'fe80::/10'
|
|
- 'fc00::/7'
|
|
- '2001:db8::/32'
|
|
- 'ff00::/8'
|
|
- 'fec0::/10'
|
|
```
|
|
---
|
|
### `ip_range_whitelist`
|
|
|
|
List of IP address CIDR ranges that should be allowed for federation,
|
|
identity servers, push servers, and for checking key validity for
|
|
third-party invite events. This is useful for specifying exceptions to
|
|
wide-ranging blacklisted target IP ranges - e.g. for communication with
|
|
a push server only visible in your network.
|
|
|
|
This whitelist overrides `ip_range_blacklist` and defaults to an empty
|
|
list.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
ip_range_whitelist:
|
|
- '192.168.1.1'
|
|
```
|
|
---
|
|
### `listeners`
|
|
|
|
List of ports that Synapse should listen on, their purpose and their
|
|
configuration.
|
|
|
|
Sub-options for each listener include:
|
|
|
|
* `port`: the TCP port to bind to.
|
|
|
|
* `tag`: An alias for the port in the logger name. If set the tag is logged instead
|
|
of the port. Default to `None`, is optional and only valid for listener with `type: http`.
|
|
See the docs [request log format](../administration/request_log.md).
|
|
|
|
* `bind_addresses`: a list of local addresses to listen on. The default is
|
|
'all local interfaces'.
|
|
|
|
* `type`: the type of listener. Normally `http`, but other valid options are:
|
|
|
|
* `manhole`: (see the docs [here](../../manhole.md)),
|
|
|
|
* `metrics`: (see the docs [here](../../metrics-howto.md)),
|
|
|
|
* `tls`: set to true to enable TLS for this listener. Will use the TLS key/cert specified in tls_private_key_path / tls_certificate_path.
|
|
|
|
* `x_forwarded`: Only valid for an 'http' listener. Set to true to use the X-Forwarded-For header as the client IP. Useful when Synapse is
|
|
behind a [reverse-proxy](../../reverse_proxy.md).
|
|
|
|
* `request_id_header`: The header extracted from each incoming request that is
|
|
used as the basis for the request ID. The request ID is used in
|
|
[logs](../administration/request_log.md#request-log-format) and tracing to
|
|
correlate and match up requests. When unset, Synapse will automatically
|
|
generate sequential request IDs. This option is useful when Synapse is behind
|
|
a [reverse-proxy](../../reverse_proxy.md).
|
|
|
|
_Added in Synapse 1.68.0._
|
|
|
|
* `resources`: Only valid for an 'http' listener. A list of resources to host
|
|
on this port. Sub-options for each resource are:
|
|
|
|
* `names`: a list of names of HTTP resources. See below for a list of valid resource names.
|
|
|
|
* `compress`: set to true to enable gzip compression on HTTP bodies for this resource. This is currently only supported with the
|
|
`client`, `consent`, `metrics` and `federation` resources.
|
|
|
|
* `additional_resources`: Only valid for an 'http' listener. A map of
|
|
additional endpoints which should be loaded via dynamic modules.
|
|
|
|
Unix socket support (_Added in Synapse 1.89.0_):
|
|
* `path`: A path and filename for a Unix socket. Make sure it is located in a
|
|
directory with read and write permissions, and that it already exists (the directory
|
|
will not be created). Defaults to `None`.
|
|
* **Note**: The use of both `path` and `port` options for the same `listener` is not
|
|
compatible.
|
|
* The `x_forwarded` option defaults to true when using Unix sockets and can be omitted.
|
|
* Other options that would not make sense to use with a UNIX socket, such as
|
|
`bind_addresses` and `tls` will be ignored and can be removed.
|
|
* `mode`: The file permissions to set on the UNIX socket. Defaults to `666`
|
|
* **Note:** Must be set as `type: http` (does not support `metrics` and `manhole`).
|
|
Also make sure that `metrics` is not included in `resources` -> `names`
|
|
|
|
|
|
Valid resource names are:
|
|
|
|
* `client`: the client-server API (/_matrix/client), and the synapse admin API (/_synapse/admin). Also implies `media` and `static`.
|
|
|
|
* `consent`: user consent forms (/_matrix/consent). See [here](../../consent_tracking.md) for more.
|
|
|
|
* `federation`: the server-server API (/_matrix/federation). Also implies `media`, `keys`, `openid`
|
|
|
|
* `keys`: the key discovery API (/_matrix/key).
|
|
|
|
* `media`: the media API (/_matrix/media).
|
|
|
|
* `metrics`: the metrics interface. See [here](../../metrics-howto.md). (Not compatible with Unix sockets)
|
|
|
|
* `openid`: OpenID authentication. See [here](../../openid.md).
|
|
|
|
* `replication`: the HTTP replication API (/_synapse/replication). See [here](../../workers.md).
|
|
|
|
* `static`: static resources under synapse/static (/_matrix/static). (Mostly useful for 'fallback authentication'.)
|
|
|
|
* `health`: the [health check endpoint](../../reverse_proxy.md#health-check-endpoint). This endpoint
|
|
is by default active for all other resources and does not have to be activated separately.
|
|
This is only useful if you want to use the health endpoint explicitly on a dedicated port or
|
|
for [workers](../../workers.md) and containers without listener e.g.
|
|
[application services](../../workers.md#notifying-application-services).
|
|

Example configuration #1:
|
|
```yaml
|
|
listeners:
|
|
# TLS-enabled listener: for when matrix traffic is sent directly to synapse.
|
|
#
|

|
|
### `manhole_settings`
|
|
|
|
Connection settings for the manhole. You can find more information
|
|
on the manhole [here](../../manhole.md). Manhole sub-options include:
|
|
* `username` : the username for the manhole. This defaults to 'matrix'.
|
|
* `password`: The password for the manhole. This defaults to 'rabbithole'.
|
|
* `ssh_priv_key_path` and `ssh_pub_key_path`: The private and public SSH key pair used to encrypt the manhole traffic.
|
|
If these are left unset, then hardcoded and non-secret keys are used,
|
|
which could allow traffic to be intercepted if sent over a public network.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
manhole_settings:
|
|
username: manhole
|
|
password: mypassword
|
|
ssh_priv_key_path: CONFDIR/id_rsa
|
|
ssh_pub_key_path: CONFDIR/id_rsa.pub
|
|
```
|
|
---
|
|
### `dummy_events_threshold`
|
|
|
|
Forward extremities can build up in a room due to networking delays between
|
|
homeservers. Once this happens in a large room, calculation of the state of
|
|
that room can become quite expensive. To mitigate this, once the number of
|
|
forward extremities reaches a given threshold, Synapse will send an
|
|
`org.matrix.dummy_event` event, which will reduce the forward extremities
|
|
in the room.
|
|
|
|
This setting defines the threshold (i.e. number of forward extremities in the room) at which dummy events are sent.
|
|
The default value is 10.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
dummy_events_threshold: 5
|
|
```
|
|
---
|
|
### `delete_stale_devices_after`
|
|
|
|
An optional duration. If set, Synapse will run a daily background task to log out and
|
|
delete any device that hasn't been accessed for more than the specified amount of time.
|
|
|
|
Defaults to no duration, which means devices are never pruned.
|
|
|
|
**Note:** This task will always run on the main process, regardless of the value of
|
|
`run_background_tasks_on`. This is due to workers currently not having the ability to
|
|
delete devices.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
delete_stale_devices_after: 1y
|
|
```
|
|
---
|
|
### `email`
|
|
|
|
Configuration for sending emails from Synapse.
|
|
|
|
Server admins can configure custom templates for email content. See
|
|
[here](../../templates.md) for more information.
|
|
|
|
This setting has the following sub-options:
|
|
* `smtp_host`: The hostname of the outgoing SMTP server to use. Defaults to 'localhost'.
|
|
* `smtp_port`: The port on the mail server for outgoing SMTP. Defaults to 465 if `force_tls` is true, else 25.
|
|
|
|
_Changed in Synapse 1.64.0:_ the default port is now aware of `force_tls`.
|
|
* `smtp_user` and `smtp_pass`: Username/password for authentication to the SMTP server. By default, no
|
|
authentication is attempted.
|
|
* `force_tls`: By default, Synapse connects over plain text and then optionally upgrades
|
|
to TLS via STARTTLS. If this option is set to true, TLS is used from the start (Implicit TLS),
|
|
and the option `require_transport_security` is ignored.
|
|
It is recommended to enable this if supported by your mail server.
|
|
|
|
_New in Synapse 1.64.0._
|
|
* `require_transport_security`: Set to true to require TLS transport security for SMTP.
|
|
By default, Synapse will connect over plain text, and will then switch to
|
|
TLS via STARTTLS *if the SMTP server supports it*. If this option is set,
|
|
Synapse will refuse to connect unless the server supports STARTTLS.
|
|
* `enable_tls`: By default, if the server supports TLS, it will be used, and the server
|
|
must present a certificate that is valid for 'smtp_host'. If this option
|
|
is set to false, TLS will not be used.
|
|
* `notif_from`: defines the "From" address to use when sending emails.
|
|
It must be set if email sending is enabled. The placeholder '%(app)s' will be replaced by the application name,
|
|
which is normally set in `app_name`, but may be overridden by the
|
|
Matrix client application. Note that the placeholder must be written '%(app)s', including the
|
|
trailing 's'.
|
|
* `app_name`: `app_name` defines the default value for '%(app)s' in `notif_from` and email
|
|
subjects. It defaults to 'Matrix'.
|
|
* `enable_notifs`: Set to true to allow users to receive e-mail notifications. If this is not set,
|
|
users can configure e-mail notifications but will not receive them. Disabled by default.
|
|
* `notif_for_new_users`: Set to false to disable automatic subscription to email
|
|
notifications for new users. Enabled by default.
|
|
* `notif_delay_before_mail`: The time to wait before emailing about a notification.
|
|
This gives the user a chance to view the message via push or an open client.
|
|
Defaults to 10 minutes.
|
|
|
|
_New in Synapse 1.99.0._
|
|
* `client_base_url`: Custom URL for client links within the email notifications. By default
|
|
links will be based on "https://matrix.to". (This setting used to be called `riot_base_url`;
|
|
the old name is still supported for backwards-compatibility but is now deprecated.)
|
|
* `validation_token_lifetime`: Configures the time that a validation email will expire after sending.
|
|
Defaults to 1h.
|
|
* `invite_client_location`: The web client location to direct users to during an invite. This is passed
|
|
to the identity server as the `org.matrix.web_client_location` key. Defaults
|
|
to unset, giving no guidance to the identity server.
|
|
* `subjects`: Subjects to use when sending emails from Synapse. The placeholder '%(app)s' will
|
|
be replaced with the value of the `app_name` setting, or by a value dictated by the Matrix client application.
|
|
In addition, each subject can use the following placeholders: '%(person)s', which will be replaced by the displayname
|
|
of the user(s) that sent the message(s), e.g. "Alice and Bob", and '%(room)s', which will be replaced by the name of the room the
|
|
message(s) have been sent to, e.g. "My super room". In addition, emails related to account administration will
|
|
can use the '%(server_name)s' placeholder, which will be replaced by the value of the
|
|
`server_name` setting in your Synapse configuration.
|
|
|
|
Here is a list of subjects for notification emails that can be set:
|
|
* `message_from_person_in_room`: Subject to use to notify about one message from one or more user(s) in a
|
|
room which has a name. Defaults to "[%(app)s] You have a message on %(app)s from %(person)s in the %(room)s room..."
|
|
* `message_from_person`: Subject to use to notify about one message from one or more user(s) in a
|
|
room which doesn't have a name. Defaults to "[%(app)s] You have a message on %(app)s from %(person)s..."
|
|
* `messages_from_person`: Subject to use to notify about multiple messages from one or more users in
|
|
a room which doesn't have a name. Defaults to "[%(app)s] You have messages on %(app)s from %(person)s..."
|
|
* `messages_in_room`: Subject to use to notify about multiple messages in a room which has a
|
|
name. Defaults to "[%(app)s] You have messages on %(app)s in the %(room)s room..."
|
|
* `messages_in_room_and_others`: Subject to use to notify about multiple messages in multiple rooms.
|
|
Defaults to "[%(app)s] You have messages on %(app)s in the %(room)s room and others..."
|
|
* `messages_from_person_and_others`: Subject to use to notify about multiple messages from multiple persons in
|
|
multiple rooms. This is similar to the setting above except it's used when
|
|
the room in which the notification was triggered has no name. Defaults to
|
|
"[%(app)s] You have messages on %(app)s from %(person)s and others..."
|
|
* `invite_from_person_to_room`: Subject to use to notify about an invite to a room which has a name.
|
|
Defaults to "[%(app)s] %(person)s has invited you to join the %(room)s room on %(app)s..."
|
|
* `invite_from_person`: Subject to use to notify about an invite to a room which doesn't have a
|
|
name. Defaults to "[%(app)s] %(person)s has invited you to chat on %(app)s..."
|
|
* `password_reset`: Subject to use when sending a password reset email. Defaults to "[%(server_name)s] Password reset"
|
|
* `email_validation`: Subject to use when sending a verification email to assert an address's
|
|
ownership. Defaults to "[%(server_name)s] Validate your email"
|
|
|

|
|
|
## Homeserver blocking
|
|
Useful options for Synapse admins.
|
|
|
|
---
|
|
|
|
### `admin_contact`
|
|
|
|
How to reach the server admin, used in `ResourceLimitError`. Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
admin_contact: 'mailto:admin@server.com'
|
|
```
|
|
---
|
|
### `hs_disabled` and `hs_disabled_message`
|
|
|
|
Blocks users from connecting to the homeserver and provides a human-readable reason
|
|
why the connection was blocked. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
hs_disabled: true
|
|
hs_disabled_message: 'Reason for why the HS is blocked'
|
|
```
|
|
---
|
|
### `limit_usage_by_mau`
|
|
|
|
This option disables/enables monthly active user blocking. Used in cases where the admin or
|
|
server owner wants to limit to the number of monthly active users. When enabled and a limit is
|
|
reached the server returns a `ResourceLimitError` with error type `Codes.RESOURCE_LIMIT_EXCEEDED`.
|
|
Defaults to false. If this is enabled, a value for `max_mau_value` must also be set.
|
|
|
|
See [Monthly Active Users](../administration/monthly_active_users.md) for details on how to configure MAU.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
limit_usage_by_mau: true
|
|
```
|
|
---
|
|
### `max_mau_value`
|
|
|
|
This option sets the hard limit of monthly active users above which the server will start
|
|
blocking user actions if `limit_usage_by_mau` is enabled. Defaults to 0.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_mau_value: 50
|
|
```
|
|
---
|
|
### `mau_trial_days`
|
|
|
|
The option `mau_trial_days` is a means to add a grace period for active users. It
|
|
means that users must be active for the specified number of days before they
|
|
can be considered active and guards against the case where lots of users
|
|
sign up in a short space of time never to return after their initial
|
|
session. Defaults to 0.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
mau_trial_days: 5
|
|
```
|
|
---
|
|
### `mau_appservice_trial_days`
|
|
|
|
The option `mau_appservice_trial_days` is similar to `mau_trial_days`, but applies a different
|
|
trial number if the user was registered by an appservice. A value
|
|
of 0 means no trial days are applied. Appservices not listed in this dictionary
|
|
use the value of `mau_trial_days` instead.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
mau_appservice_trial_days:
|
|
my_appservice_id: 3
|
|
another_appservice_id: 6
|
|
```
|
|
---
|
|
### `mau_limit_alerting`
|
|
|
|
The option `mau_limit_alerting` is a means of limiting client-side alerting
|
|
should the mau limit be reached. This is useful for small instances
|
|
where the admin has 5 mau seats (say) for 5 specific people and no
|
|
interest increasing the mau limit further. Defaults to true, which
|
|
means that alerting is enabled.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
mau_limit_alerting: false
|
|
```
|
|
---
|
|
### `mau_stats_only`
|
|
|
|
If enabled, the metrics for the number of monthly active users will
|
|
be populated, however no one will be limited based on these numbers. If `limit_usage_by_mau`
|
|
is true, this is implied to be true. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
mau_stats_only: true
|
|
```
|
|
---
|
|
### `mau_limit_reserved_threepids`
|
|
|
|
Sometimes the server admin will want to ensure certain accounts are
|
|
never blocked by mau checking. These accounts are specified by this option.
|
|
Defaults to none. Add accounts by specifying the `medium` and `address` of the
|
|
reserved threepid (3rd party identifier).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
mau_limit_reserved_threepids:
|
|
- medium: 'email'
|
|
address: 'reserved_user@example.com'
|
|
```
|
|
---
|
|
### `server_context`
|
|
|
|
This option is used by phonehome stats to group together related servers.
|
|
Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
server_context: context
|
|
```
|
|
---
|
|
### `limit_remote_rooms`
|
|
|
|
When this option is enabled, the room "complexity" will be checked before a user
|
|
joins a new remote room. If it is above the complexity limit, the server will
|
|
disallow joining, or will instantly leave. This is useful for homeservers that are
|
|
resource-constrained. Options for this setting include:
|
|
* `enabled`: whether this check is enabled. Defaults to false.
|
|
* `complexity`: the limit above which rooms cannot be joined. The default is 1.0.
|
|
* `complexity_error`: override the error which is returned when the room is too complex with a
|
|
custom message.
|
|
* `admins_can_join`: allow server admins to join complex rooms. Default is false.
|
|
|
|
Room complexity is an arbitrary measure based on factors such as the number of
|
|
users in the room.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
limit_remote_rooms:
|
|
enabled: true
|
|
complexity: 0.5
|
|
complexity_error: "I can't let you do that, Dave."
|
|
admins_can_join: true
|
|
```
|
|
---
|
|
### `require_membership_for_aliases`
|
|
|
|
Whether to require a user to be in the room to add an alias to it.
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
require_membership_for_aliases: false
|
|
```
|
|
---
|
|
### `allow_per_room_profiles`
|
|
|
|
Whether to allow per-room membership profiles through the sending of membership
|
|
events with profile information that differs from the target's global profile.
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_per_room_profiles: false
|
|
```
|
|
---
|
|
### `max_avatar_size`
|
|
|
|
The largest permissible file size in bytes for a user avatar. Defaults to no restriction.
|
|
Use M for MB and K for KB.
|
|
|
|
Note that user avatar changes will not work if this is set without using Synapse's media repository.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_avatar_size: 10M
|
|
```
|
|
---
|
|
### `allowed_avatar_mimetypes`
|
|
|
|
The MIME types allowed for user avatars. Defaults to no restriction.
|
|
|
|
Note that user avatar changes will not work if this is set without
|
|
using Synapse's media repository.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allowed_avatar_mimetypes: ["image/png", "image/jpeg", "image/gif"]
|
|
```
|
|
---
|
|
### `redaction_retention_period`
|
|
|
|
How long to keep redacted events in unredacted form in the database. After
|
|
this period redacted events get replaced with their redacted form in the DB.
|
|
|
|
Synapse will check whether the rentention period has concluded for redacted
|
|
events every 5 minutes. Thus, even if this option is set to `0`, Synapse may
|
|
still take up to 5 minutes to purge redacted events from the database.
|
|
|
|
Defaults to `7d`. Set to `null` to disable.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
redaction_retention_period: 28d
|
|
```
|
|
---
|
|
### `forgotten_room_retention_period`
|
|
|
|
How long to keep locally forgotten rooms before purging them from the DB.
|
|
|
|
Defaults to `null`, meaning it's disabled.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
forgotten_room_retention_period: 28d
|
|
```
|
|
---
|
|
### `user_ips_max_age`
|
|
|
|
How long to track users' last seen time and IPs in the database.
|
|
|
|
Defaults to `28d`. Set to `null` to disable clearing out of old rows.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
user_ips_max_age: 14d
|
|
```
|
|
---
|
|
### `request_token_inhibit_3pid_errors`
|
|
|
|
Inhibits the `/requestToken` endpoints from returning an error that might leak
|
|
information about whether an e-mail address is in use or not on this
|
|
homeserver. Defaults to false.
|
|
Note that for some endpoints the error situation is the e-mail already being
|
|
used, and for others the error is entering the e-mail being unused.
|
|
If this option is enabled, instead of returning an error, these endpoints will
|
|
act as if no error happened and return a fake session ID ('sid') to clients.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
request_token_inhibit_3pid_errors: true
|
|
```
|
|
---
|
|
### `next_link_domain_whitelist`
|
|
|
|
A list of domains that the domain portion of `next_link` parameters
|
|
must match.
|
|
|
|
This parameter is optionally provided by clients while requesting
|
|
validation of an email or phone number, and maps to a link that
|
|
users will be automatically redirected to after validation
|
|
succeeds. Clients can make use this parameter to aid the validation
|
|
process.
|
|
|
|
The whitelist is applied whether the homeserver or an identity server is handling validation.
|
|
|
|
The default value is no whitelist functionality; all domains are
|
|
allowed. Setting this value to an empty list will instead disallow
|
|
all domains.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
next_link_domain_whitelist: ["matrix.org"]
|
|
```
|
|
---
|
|
### `templates` and `custom_template_directory`
|
|
|
|
These options define templates to use when generating email or HTML page contents.
|
|
The `custom_template_directory` determines which directory Synapse will try to
|
|
find template files in to use to generate email or HTML page contents.
|
|
If not set, or a file is not found within the template directory, a default
|
|
template from within the Synapse package will be used.
|
|
|
|
See [here](../../templates.md) for more
|
|
information about using custom templates.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
templates:
|
|
custom_template_directory: /path/to/custom/templates/
|
|
```
|
|
---
|
|
### `retention`
|
|
|
|
This option and the associated options determine message retention policy at the
|
|
server level.
|
|
|
|
Room admins and mods can define a retention period for their rooms using the
|
|
`m.room.retention` state event, and server admins can cap this period by setting
|
|
the `allowed_lifetime_min` and `allowed_lifetime_max` config options.
|
|
|
|
If this feature is enabled, Synapse will regularly look for and purge events
|
|
which are older than the room's maximum retention period. Synapse will also
|
|
filter events received over federation so that events that should have been
|
|
purged are ignored and not stored again.
|
|
|
|
The message retention policies feature is disabled by default. You can read more
|
|
about this feature [here](../../message_retention_policies.md).
|
|
|
|
This setting has the following sub-options:
|
|
* `default_policy`: Default retention policy. If set, Synapse will apply it to rooms that lack the
|
|
'm.room.retention' state event. This option is further specified by the
|
|
`min_lifetime` and `max_lifetime` sub-options associated with it. Note that the
|
|
value of `min_lifetime` doesn't matter much because Synapse doesn't take it into account yet.
|
|
|
|
* `allowed_lifetime_min` and `allowed_lifetime_max`: Retention policy limits. If
|
|
set, and the state of a room contains a `m.room.retention` event in its state
|
|
which contains a `min_lifetime` or a `max_lifetime` that's out of these bounds,
|
|
Synapse will cap the room's policy to these limits when running purge jobs.
|
|
|
|
* `purge_jobs` and the associated `shortest_max_lifetime` and `longest_max_lifetime` sub-options:
|
|
Server admins can define the settings of the background jobs purging the
|
|
events whose lifetime has expired under the `purge_jobs` section.
|
|
|
|
If no configuration is provided for this option, a single job will be set up to delete
|
|
expired events in every room daily.
|
|
|
|
Each job's configuration defines which range of message lifetimes the job
|
|
takes care of. For example, if `shortest_max_lifetime` is '2d' and
|
|
`longest_max_lifetime` is '3d', the job will handle purging expired events in
|
|
rooms whose state defines a `max_lifetime` that's both higher than 2 days, and
|
|
lower than or equal to 3 days. Both the minimum and the maximum value of a
|
|
range are optional, e.g. a job with no `shortest_max_lifetime` and a
|
|
`longest_max_lifetime` of '3d' will handle every room with a retention policy
|
|
whose `max_lifetime` is lower than or equal to three days.
|
|
|
|
The rationale for this per-job configuration is that some rooms might have a
|
|
retention policy with a low `max_lifetime`, where history needs to be purged
|
|
of outdated messages on a more frequent basis than for the rest of the rooms
|
|
(e.g. every 12h), but not want that purge to be performed by a job that's
|
|
iterating over every room it knows, which could be heavy on the server.
|
|
|
|
If any purge job is configured, it is strongly recommended to have at least
|
|
a single job with neither `shortest_max_lifetime` nor `longest_max_lifetime`
|
|
set, or one job without `shortest_max_lifetime` and one job without
|
|
`longest_max_lifetime` set. Otherwise some rooms might be ignored, even if
|
|
`allowed_lifetime_min` and `allowed_lifetime_max` are set, because capping a
|
|
room's policy to these values is done after the policies are retrieved from
|
|
Synapse's database (which is done using the range specified in a purge job's
|
|
configuration).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
retention:
|
|
enabled: true
|
|
default_policy:
|
|
min_lifetime: 1d
|
|
max_lifetime: 1y
|
|
allowed_lifetime_min: 1d
|
|
allowed_lifetime_max: 1y
|
|
purge_jobs:
|
|
- longest_max_lifetime: 3d
|
|
interval: 12h
|
|
- shortest_max_lifetime: 3d
|
|
interval: 1d
|
|
```
|

|
|
## TLS
|
|
|
|
Options related to TLS.
|
|
|
|
---
|
|
### `tls_certificate_path`
|
|
|
|
This option specifies a PEM-encoded X509 certificate for TLS.
|
|
This certificate, as of Synapse 1.0, will need to be a valid and verifiable
|
|
certificate, signed by a recognised Certificate Authority. Defaults to none.
|
|
|
|
Be sure to use a `.pem` file that includes the full certificate chain including
|
|
any intermediate certificates (for instance, if using certbot, use
|
|
`fullchain.pem` as your certificate, not `cert.pem`).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
tls_certificate_path: "CONFDIR/SERVERNAME.tls.crt"
|
|
```
|
|
---
|
|
### `tls_private_key_path`
|
|
|
|
PEM-encoded private key for TLS. Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
tls_private_key_path: "CONFDIR/SERVERNAME.tls.key"
|
|
```
|
|
---
|
|
### `federation_verify_certificates`
|
|
Whether to verify TLS server certificates for outbound federation requests.
|
|
|
|
Defaults to true. To disable certificate verification, set the option to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_verify_certificates: false
|
|
```
|
|
---
|
|
### `federation_client_minimum_tls_version`
|
|
|
|
The minimum TLS version that will be used for outbound federation requests.
|
|
|
|
Defaults to `"1"`. Configurable to `"1"`, `"1.1"`, `"1.2"`, or `"1.3"`. Note
|
|
that setting this value higher than `"1.2"` will prevent federation to most
|
|
of the public Matrix network: only configure it to `"1.3"` if you have an
|
|
entirely private federation setup and you can ensure TLS 1.3 support.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_client_minimum_tls_version: "1.2"
|
|
```
|
|
---
|
|
### `federation_certificate_verification_whitelist`
|
|
|
|
Skip federation certificate verification on a given whitelist
|
|
of domains.
|
|
|
|
This setting should only be used in very specific cases, such as
|
|
federation over Tor hidden services and similar. For private networks
|
|
of homeservers, you likely want to use a private CA instead.
|
|
|
|
Only effective if `federation_verify_certificates` is `true`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_certificate_verification_whitelist:
|
|
- lon.example.com
|
|
- "*.domain.com"
|
|
- "*.onion"
|
|
```
|
|
---
|
|
### `federation_custom_ca_list`
|
|
|
|
List of custom certificate authorities for federation traffic.
|
|
|
|
This setting should only normally be used within a private network of
|
|
homeservers.
|
|
|
|
Note that this list will replace those that are provided by your
|
|
operating environment. Certificates must be in PEM format.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_custom_ca_list:
|
|
- myCA1.pem
|
|
- myCA2.pem
|
|
- myCA3.pem
|
|
```
|
|
---
|
|
## Federation
|
|
|
|
Options related to federation.
|
|
|
|
---
|
|
### `federation_domain_whitelist`
|
|
|
|
Restrict federation to the given whitelist of domains.
|
|
N.B. we recommend also firewalling your federation listener to limit
|
|
inbound federation traffic as early as possible, rather than relying
|
|
purely on this application-layer restriction. If not specified, the
|
|
default is to whitelist everything.
|
|
|
|
Note: this does not stop a server from joining rooms that servers not on the
|
|
whitelist are in. As such, this option is really only useful to establish a
|
|
"private federation", where a group of servers all whitelist each other and have
|
|
the same whitelist.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_domain_whitelist:
|
|
- lon.example.com
|
|
- nyc.example.com
|
|
- syd.example.com
|
|
```
|
|
---
|
|
### `federation_whitelist_endpoint_enabled`
|
|
|
|
Enables an endpoint for fetching the federation whitelist config.
|
|
|
|
The request method and path is `GET /_synapse/client/v1/config/federation_whitelist`, and the
|
|
response format is:
|
|
|
|
```json
|
|
{
|
|
"whitelist_enabled": true, // Whether the federation whitelist is being enforced
|
|
"whitelist": [ // Which server names are allowed by the whitelist
|
|
"example.com"
|
|
]
|
|
}
|
|
```
|
|
|
|
If `whitelist_enabled` is `false` then the server is permitted to federate with all others.
|
|
|
|
The endpoint requires authentication.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_whitelist_endpoint_enabled: true
|
|
```
|
|
---
|
|
### `federation_metrics_domains`
|
|
|
|
Report prometheus metrics on the age of PDUs being sent to and received from
|
|
the given domains. This can be used to give an idea of "delay" on inbound
|
|
and outbound federation, though be aware that any delay can be due to problems
|
|
at either end or with the intermediate network.
|
|
|
|
By default, no domains are monitored in this way.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_metrics_domains:
|
|
- matrix.org
|
|
- example.com
|
|
```
|
|
---
|
|
### `allow_profile_lookup_over_federation`
|
|
|
|
Set to false to disable profile lookup over federation. By default, the
|
|
Federation API allows other homeservers to obtain profile data of any user
|
|
on this homeserver.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_profile_lookup_over_federation: false
|
|
```
|
|
---
|
|
### `allow_device_name_lookup_over_federation`
|
|
|
|
Set this option to true to allow device display name lookup over federation. By default, the
|
|
Federation API prevents other homeservers from obtaining the display names of any user devices
|
|
on this homeserver.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_device_name_lookup_over_federation: true
|
|
```
|
|
---
|
|
### `federation`
|
|
|
|
The federation section defines some sub-options related to federation.
|
|
|
|
The following options are related to configuring timeout and retry logic for one request,
|
|
independently of the others.
|
|
Short retry algorithm is used when something or someone will wait for the request to have an
|
|
answer, while long retry is used for requests that happen in the background,
|
|
like sending a federation transaction.
|
|
|
|
* `client_timeout`: timeout for the federation requests. Default to 60s.
|
|
* `max_short_retry_delay`: maximum delay to be used for the short retry algo. Default to 2s.
|
|
* `max_long_retry_delay`: maximum delay to be used for the short retry algo. Default to 60s.
|
|
* `max_short_retries`: maximum number of retries for the short retry algo. Default to 3 attempts.
|
|
* `max_long_retries`: maximum number of retries for the long retry algo. Default to 10 attempts.
|
|
|
|
The following options control the retry logic when communicating with a specific homeserver destination.
|
|
Unlike the previous configuration options, these values apply across all requests
|
|
for a given destination and the state of the backoff is stored in the database.
|
|
|
|
* `destination_min_retry_interval`: the initial backoff, after the first request fails. Defaults to 10m.
|
|
* `destination_retry_multiplier`: how much we multiply the backoff by after each subsequent fail. Defaults to 2.
|
|
* `destination_max_retry_interval`: a cap on the backoff. Defaults to a week.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation:
|
|
client_timeout: 180s
|
|
max_short_retry_delay: 7s
|
|
max_long_retry_delay: 100s
|
|
max_short_retries: 5
|
|
max_long_retries: 20
|
|
destination_min_retry_interval: 30s
|
|
destination_retry_multiplier: 5
|
|
destination_max_retry_interval: 12h
|
|
```
|
|
---
|
|
## Caching
|
|
|
|
Options related to caching.
|
|
|
|
---
|
|
### `event_cache_size`
|
|
|
|
The number of events to cache in memory. Defaults to 10K. Like other caches,
|
|
this is affected by `caches.global_factor` (see below).
|
|
|
|
For example, the default is 10K and the global_factor default is 0.5.
|
|
|
|
Since 10K * 0.5 is 5K then the event cache size will be 5K.
|
|
|
|
The cache affected by this configuration is named as "*getEvent*".
|
|
|
|
Note that this option is not part of the `caches` section.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
event_cache_size: 15K
|
|
```
|
|
---
|
|
### `caches` and associated values
|
|
|
|
A cache 'factor' is a multiplier that can be applied to each of
|
|
Synapse's caches in order to increase or decrease the maximum
|
|
number of entries that can be stored.
|
|
|
|
`caches` can be configured through the following sub-options:
|
|
|
|
* `global_factor`: Controls the global cache factor, which is the default cache factor
|
|
for all caches if a specific factor for that cache is not otherwise
|
|
set.
|
|
|
|
This can also be set by the `SYNAPSE_CACHE_FACTOR` environment
|
|
variable. Setting by environment variable takes priority over
|
|
setting through the config file.
|
|
|
|
Defaults to 0.5, which will halve the size of all caches.
|
|
|
|
Note that changing this value also affects the HTTP connection pool.
|
|
|
|
* `per_cache_factors`: A dictionary of cache name to cache factor for that individual
|
|
cache. Overrides the global cache factor for a given cache.
|
|
|
|
These can also be set through environment variables comprised
|
|
of `SYNAPSE_CACHE_FACTOR_` + the name of the cache in capital
|
|
letters and underscores. Setting by environment variable
|
|
takes priority over setting through the config file.
|
|
Ex. `SYNAPSE_CACHE_FACTOR_GET_USERS_WHO_SHARE_ROOM_WITH_USER=2.0`
|
|
|
|
Some caches have '*' and other characters that are not
|
|
alphanumeric or underscores. These caches can be named with or
|
|
without the special characters stripped. For example, to specify
|
|
the cache factor for `*stateGroupCache*` via an environment
|
|
variable would be `SYNAPSE_CACHE_FACTOR_STATEGROUPCACHE=2.0`.
|
|
|
|
* `expire_caches`: Controls whether cache entries are evicted after a specified time
|
|
period. Defaults to true. Set to false to disable this feature. Note that never expiring
|
|
caches may result in excessive memory usage.
|
|
|
|
* `cache_entry_ttl`: If `expire_caches` is enabled, this flag controls how long an entry can
|
|
be in a cache without having been accessed before being evicted.
|
|
Defaults to 30m.
|
|
|
|
* `sync_response_cache_duration`: Controls how long the results of a /sync request are
|
|
cached for after a successful response is returned. A higher duration can help clients
|
|
with intermittent connections, at the cost of higher memory usage.
|
|
A value of zero means that sync responses are not cached.
|
|
Defaults to 2m.
|
|
|
|
*Changed in Synapse 1.62.0*: The default was changed from 0 to 2m.
|
|
|
|
* `cache_autotuning` and its sub-options `max_cache_memory_usage`, `target_cache_memory_usage`, and
|
|
`min_cache_ttl` work in conjunction with each other to maintain a balance between cache memory
|
|
usage and cache entry availability. You must be using [jemalloc](../administration/admin_faq.md#help-synapse-is-slow-and-eats-all-my-ramcpu)
|
|
to utilize this option, and all three of the options must be specified for this feature to work. This option
|
|
defaults to off, enable it by providing values for the sub-options listed below. Please note that the feature will not work
|
|
and may cause unstable behavior (such as excessive emptying of caches or exceptions) if all of the values are not provided.
|
|
Please see the [Config Conventions](#config-conventions) for information on how to specify memory size and cache expiry
|
|
durations.
|
|
* `max_cache_memory_usage` sets a ceiling on how much memory the cache can use before caches begin to be continuously evicted.
|
|
They will continue to be evicted until the memory usage drops below the `target_memory_usage`, set in
|
|
the setting below, or until the `min_cache_ttl` is hit. There is no default value for this option.
|
|
* `target_cache_memory_usage` sets a rough target for the desired memory usage of the caches. There is no default value
|
|
for this option.
|
|
* `min_cache_ttl` sets a limit under which newer cache entries are not evicted and is only applied when
|
|
caches are actively being evicted/`max_cache_memory_usage` has been exceeded. This is to protect hot caches
|
|
from being emptied while Synapse is evicting due to memory. There is no default value for this option.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
event_cache_size: 15K
|
|
caches:
|
|
global_factor: 1.0
|
|
per_cache_factors:
|
|
get_users_who_share_room_with_user: 2.0
|
|
sync_response_cache_duration: 2m
|
|
cache_autotuning:
|
|
max_cache_memory_usage: 1024M
|
|
target_cache_memory_usage: 758M
|
|
min_cache_ttl: 5m
|
|
```
|
|
|
|
### Reloading cache factors
|
|
|
|
The cache factors (i.e. `caches.global_factor` and `caches.per_cache_factors`) may be reloaded at any time by sending a
|
|
[`SIGHUP`](https://en.wikipedia.org/wiki/SIGHUP) signal to Synapse using e.g.
|
|
|
|
```commandline
|
|
kill -HUP [PID_OF_SYNAPSE_PROCESS]
|
|
```
|
|
|
|
If you are running multiple workers, you must individually update the worker
|
|
config file and send this signal to each worker process.
|
|
|
|
If you're using the [example systemd service](https://github.com/element-hq/synapse/blob/develop/contrib/systemd/matrix-synapse.service)
|
|
file in Synapse's `contrib` directory, you can send a `SIGHUP` signal by using
|
|
`systemctl reload matrix-synapse`.
|
|
|

|
|
## Database
|
|
Config options related to database settings.
|
|
|
|
---
|
|
### `database`
|
|
|
|
The `database` setting defines the database that synapse uses to store all of
|
|
its data.
|
|
|
|
Associated sub-options:
|
|
|
|
* `name`: this option specifies the database engine to use: either `sqlite3` (for SQLite)
|
|
or `psycopg2` (for PostgreSQL). If no name is specified Synapse will default to SQLite.
|
|
|
|
* `txn_limit` gives the maximum number of transactions to run per connection
|
|
before reconnecting. Defaults to 0, which means no limit.
|
|
|
|
* `allow_unsafe_locale` is an option specific to Postgres. Under the default behavior, Synapse will refuse to
|
|
start if the postgres db is set to a non-C locale. You can override this behavior (which is *not* recommended)
|
|
by setting `allow_unsafe_locale` to true. Note that doing so may corrupt your database. You can find more information
|
|
[here](../../postgres.md#fixing-incorrect-collate-or-ctype) and [here](https://wiki.postgresql.org/wiki/Locale_data_changes).
|
|
|
|
* `args` gives options which are passed through to the database engine,

### `databases`
|
|
|
|
The `databases` option allows specifying a mapping between certain database tables and
|
|
database host details, spreading the load of a single Synapse instance across multiple
|
|
database backends. This is often referred to as "database sharding". This option is only
|
|
supported for PostgreSQL database backends.
|
|
|
|
**Important note:** This is a supported option, but is not currently used in production by the
|
|
Matrix.org Foundation. Proceed with caution and always make backups.
|
|
|
|
`databases` is a dictionary of arbitrarily-named database entries. Each entry is equivalent
|
|
to the value of the `database` homeserver config option (see above), with the addition of
|
|
a `data_stores` key. `data_stores` is an array of strings that specifies the data store(s)
|
|
(a defined label for a set of tables) that should be stored on the associated database
|
|
backend entry.
|
|
|
|
The currently defined values for `data_stores` are:
|
|
|
|
* `"state"`: Database that relates to state groups will be stored in this database.
|
|
|
|
Specifically, that means the following tables:
|
|
* `state_groups`
|
|
* `state_group_edges`
|
|
* `state_groups_state`
|
|
|
|
And the following sequences:
|
|
* `state_groups_seq_id`
|
|
|
|
* `"main"`: All other database tables and sequences.
|
|
|
|
All databases will end up with additional tables used for tracking database schema migrations
|
|
and any pending background updates. Synapse will create these automatically on startup when checking for
|
|
and/or performing database schema migrations.
|
|
|
|
To migrate an existing database configuration (e.g. all tables on a single database) to a different
|
|
configuration (e.g. the "main" data store on one database, and "state" on another), do the following:
|
|
|
|
1. Take a backup of your existing database. Things can and do go wrong and database corruption is no joke!
|
|
2. Ensure all pending database migrations have been applied and background updates have run. The simplest
|
|
way to do this is to use the `update_synapse_database` script supplied with your Synapse installation.
|
|
|
|
```sh
|
|
update_synapse_database --database-config homeserver.yaml --run-background-updates
|
|
```
|
|
|
|
3. Copy over the necessary tables and sequences from one database to the other. Tables relating to database
|
|
migrations, schemas, schema versions and background updates should **not** be copied.
|
|
|
|
As an example, say that you'd like to split out the "state" data store from an existing database which
|
|
currently contains all data stores.
|
|
|
|
Simply copy the tables and sequences defined above for the "state" datastore from the existing database
|
|
to the secondary database. As noted above, additional tables will be created in the secondary database
|
|
when Synapse is started.
|
|
|
|
4. Modify/create the `databases` option in your `homeserver.yaml` to match the desired database configuration.
|
|
5. Start Synapse. Check that it starts up successfully and that things generally seem to be working.
|
|
6. Drop the old tables that were copied in step 3.
|
|
|
|
Only one of the options `database` or `databases` may be specified in your config, but not both.
|
|
|
|
Example configuration:
|
|
|
|
```yaml
|
|
databases:
|
|
basement_box:
|
|
name: psycopg2
|
|
txn_limit: 10000
|
|
data_stores: ["main"]
|
|
args:
|
|
user: synapse_user
|
|
password: secretpassword
|
|
dbname: synapse_main
|
|
host: localhost
|
|
port: 5432
|
|
cp_min: 5
|
|
cp_max: 10
|
|
|
|
my_other_database:
|
|
name: psycopg2
|
|
txn_limit: 10000
|
|
data_stores: ["state"]
|
|
args:
|
|
user: synapse_user
|
|
password: secretpassword
|
|
dbname: synapse_state
|
|
host: localhost
|
|
port: 5432
|
|
cp_min: 5
|
|
cp_max: 10
|
|
```

|
## Logging
|
|
Config options related to logging.
|
|
|
|
---
|
|
### `log_config`
|
|
|
|
This option specifies a yaml python logging config file as described
|
|
[here](https://docs.python.org/3/library/logging.config.html#configuration-dictionary-schema).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
log_config: "CONFDIR/SERVERNAME.log.config"
|
|
```
|
|
---
|
|
## Ratelimiting
|
|
Options related to ratelimiting in Synapse.
|
|
|
|
Each ratelimiting configuration is made of two parameters:
|
|
- `per_second`: number of requests a client can send per second.
|
|
- `burst_count`: number of requests a client can send before being throttled.
|
|
---
|
|
### `rc_message`
|
|
|
|
|
|
Ratelimiting settings for client messaging.
|
|
|
|
This is a ratelimiting option for messages that ratelimits sending based on the account the client
|
|
is using. It defaults to: `per_second: 0.2`, `burst_count: 10`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_message:
|
|
per_second: 0.5
|
|
burst_count: 15
|
|
```
|
|
---
|
|
### `rc_registration`
|
|
|
|
This option ratelimits registration requests based on the client's IP address.
|
|
It defaults to `per_second: 0.17`, `burst_count: 3`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_registration:
|
|
per_second: 0.15
|
|
burst_count: 2
|
|
```
|
|
---
|
|
### `rc_registration_token_validity`
|
|
|
|
This option checks the validity of registration tokens that ratelimits requests based on
|
|
the client's IP address.
|
|
Defaults to `per_second: 0.1`, `burst_count: 5`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_registration_token_validity:
|
|
per_second: 0.3
|
|
burst_count: 6
|
|
```
|
|
---
|
|
### `rc_login`
|
|
|
|
This option specifies several limits for login:
|
|
* `address` ratelimits login requests based on the client's IP
|
|
address. Defaults to `per_second: 0.003`, `burst_count: 5`.
|
|
|
|
* `account` ratelimits login requests based on the account the
|
|
client is attempting to log into. Defaults to `per_second: 0.003`,
|
|
`burst_count: 5`.
|
|
|
|
* `failed_attempts` ratelimits login requests based on the account the
|
|
client is attempting to log into, based on the amount of failed login
|
|
attempts for this account. Defaults to `per_second: 0.17`, `burst_count: 3`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_login:
|
|
address:
|
|
per_second: 0.15
|
|
burst_count: 5
|
|
account:
|
|
per_second: 0.18
|
|
burst_count: 4
|
|
failed_attempts:
|
|
per_second: 0.19
|
|
burst_count: 7
|
|
```
|
|
---
|
|
### `rc_admin_redaction`
|
|
|
|
This option sets ratelimiting redactions by room admins. If this is not explicitly
|
|
set then it uses the same ratelimiting as per `rc_message`. This is useful
|
|
to allow room admins to deal with abuse quickly.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_admin_redaction:
|
|
per_second: 1
|
|
burst_count: 50
|
|
```
|
|
---
|
|
### `rc_joins`
|
|
|
|
This option allows for ratelimiting number of rooms a user can join. This setting has the following sub-options:
|
|
|
|
* `local`: ratelimits when users are joining rooms the server is already in.
|
|
Defaults to `per_second: 0.1`, `burst_count: 10`.
|
|
|
|
* `remote`: ratelimits when users are trying to join rooms not on the server (which
|
|
can be more computationally expensive than restricting locally). Defaults to
|
|
`per_second: 0.01`, `burst_count: 10`
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_joins:
|
|
local:
|
|
per_second: 0.2
|
|
burst_count: 15
|
|
remote:
|
|
per_second: 0.03
|
|
burst_count: 12
|
|
```
|
|
---
|
|
### `rc_joins_per_room`
|
|
|
|
This option allows admins to ratelimit joins to a room based on the number of recent
|
|
joins (local or remote) to that room. It is intended to mitigate mass-join spam
|
|
waves which target multiple homeservers.
|
|
|
|
By default, one join is permitted to a room every second, with an accumulating
|
|
buffer of up to ten instantaneous joins.
|
|
|
|
Example configuration (default values):
|
|
```yaml
|
|
rc_joins_per_room:
|
|
per_second: 1
|
|
burst_count: 10
|
|
```
|
|
|
|
_Added in Synapse 1.64.0._
|
|
|
|
---
|
|
### `rc_3pid_validation`
|
|
|
|
This option ratelimits how often a user or IP can attempt to validate a 3PID.
|
|
Defaults to `per_second: 0.003`, `burst_count: 5`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_3pid_validation:
|
|
per_second: 0.003
|
|
burst_count: 5
|
|
```
|
|
---
|
|
### `rc_invites`
|
|
|
|
This option sets ratelimiting how often invites can be sent in a room or to a
|
|
specific user. `per_room` defaults to `per_second: 0.3`, `burst_count: 10`,
|
|
`per_user` defaults to `per_second: 0.003`, `burst_count: 5`, and `per_issuer`
|
|
defaults to `per_second: 0.3`, `burst_count: 10`.
|
|
|
|
Client requests that invite user(s) when [creating a
|
|
room](https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3createroom)
|
|
will count against the `rc_invites.per_room` limit, whereas
|
|
client requests to [invite a single user to a
|
|
room](https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3roomsroomidinvite)
|
|
will count against both the `rc_invites.per_user` and `rc_invites.per_room` limits.
|
|
|
|
Federation requests to invite a user will count against the `rc_invites.per_user`
|
|
limit only, as Synapse presumes ratelimiting by room will be done by the sending server.
|
|
|
|
The `rc_invites.per_user` limit applies to the *receiver* of the invite, rather than the
|
|
sender, meaning that a `rc_invite.per_user.burst_count` of 5 mandates that a single user
|
|
cannot *receive* more than a burst of 5 invites at a time.
|
|
|
|
In contrast, the `rc_invites.per_issuer` limit applies to the *issuer* of the invite, meaning that a `rc_invite.per_issuer.burst_count` of 5 mandates that single user cannot *send* more than a burst of 5 invites at a time.
|
|
|
|
_Changed in version 1.63:_ added the `per_issuer` limit.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_invites:
|
|
per_room:
|
|
per_second: 0.5
|
|
burst_count: 5
|
|
per_user:
|
|
per_second: 0.004
|
|
burst_count: 3
|
|
per_issuer:
|
|
per_second: 0.5
|
|
burst_count: 5
|
|
```
|
|
|
|
---
|
|
### `rc_third_party_invite`
|
|
|
|
This option ratelimits 3PID invites (i.e. invites sent to a third-party ID
|
|
such as an email address or a phone number) based on the account that's
|
|
sending the invite. Defaults to `per_second: 0.2`, `burst_count: 10`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_third_party_invite:
|
|
per_second: 0.2
|
|
burst_count: 10
|
|
```
|
|
---
|
|
### `rc_media_create`
|
|
|
|
This option ratelimits creation of MXC URIs via the `/_matrix/media/v1/create`
|
|
endpoint based on the account that's creating the media. Defaults to
|
|
`per_second: 10`, `burst_count: 50`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_media_create:
|
|
per_second: 10
|
|
burst_count: 50
|
|
```
|
|
---
|
|
### `rc_federation`
|
|
|
|
Defines limits on federation requests.
|
|
|
|
The `rc_federation` configuration has the following sub-options:
|
|
* `window_size`: window size in milliseconds. Defaults to 1000.
|
|
* `sleep_limit`: number of federation requests from a single server in
|
|
a window before the server will delay processing the request. Defaults to 10.
|
|
* `sleep_delay`: duration in milliseconds to delay processing events
|
|
from remote servers by if they go over the sleep limit. Defaults to 500.
|
|
* `reject_limit`: maximum number of concurrent federation requests
|
|
allowed from a single server. Defaults to 50.
|
|
* `concurrent`: number of federation requests to concurrently process
|
|
from a single server. Defaults to 3.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
rc_federation:
|
|
window_size: 750
|
|
sleep_limit: 15
|
|
sleep_delay: 400
|
|
reject_limit: 40
|
|
concurrent: 5
|
|
```
|
|
---
|
|
### `federation_rr_transactions_per_room_per_second`
|
|
|
|
Sets outgoing federation transaction frequency for sending read-receipts,
|
|
per-room.
|
|
|
|
If we end up trying to send out more read-receipts, they will get buffered up
|
|
into fewer transactions. Defaults to 50.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
federation_rr_transactions_per_room_per_second: 40
|
|
```
|
|
---
|
|
## Media Store
|
|
Config options related to Synapse's media store.
|
|
|
|
---
|
|
### `enable_authenticated_media`
|
|
|
|
When set to true, all subsequent media uploads will be marked as authenticated, and will not be available over legacy
|
|
unauthenticated media endpoints (`/_matrix/media/(r0|v3|v1)/download` and `/_matrix/media/(r0|v3|v1)/thumbnail`) - requests for authenticated media over these endpoints will result in a 404. All media, including authenticated media, will be available over the authenticated media endpoints `_matrix/client/v1/media/download` and `_matrix/client/v1/media/thumbnail`. Media uploaded prior to setting this option to true will still be available over the legacy endpoints. Note if the setting is switched to false
|
|
after enabling, media marked as authenticated will be available over legacy endpoints. Defaults to false, but
|
|
this will change to true in a future Synapse release.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_authenticated_media: true
|
|
```
|
|
---
|
|
### `enable_media_repo`
|
|
|
|
Enable the media store service in the Synapse master. Defaults to true.
|
|
Set to false if you are using a separate media store worker.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_media_repo: false
|
|
```
|
|
---
|
|
### `media_store_path`
|
|
|
|
Directory where uploaded images and attachments are stored.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
media_store_path: "DATADIR/media_store"
|
|
```
|
|
---
|
|
### `max_pending_media_uploads`
|
|
|
|
How many *pending media uploads* can a given user have? A pending media upload
|
|
is a created MXC URI that (a) is not expired (the `unused_expires_at` timestamp
|
|
has not passed) and (b) the media has not yet been uploaded for. Defaults to 5.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_pending_media_uploads: 5
|
|
```
|
|
---
|
|
### `unused_expiration_time`
|
|
|
|
How long to wait in milliseconds before expiring created media IDs. Defaults to
|
|
"24h"
|
|
|
|
Example configuration:
|
|
```yaml
|
|
unused_expiration_time: "1h"
|
|
```
|
|
---
|
|
### `media_storage_providers`
|
|
|
|
Media storage providers allow media to be stored in different
|
|
locations. Defaults to none. Associated sub-options are:
|
|
* `module`: type of resource, e.g. `file_system`.
|
|
* `store_local`: whether to store newly uploaded local files
|
|
* `store_remote`: whether to store newly downloaded local files
|
|
* `store_synchronous`: whether to wait for successful storage for local uploads
|
|
* `config`: sets a path to the resource through the `directory` option
|
|
|
|
Example configuration:
|
|
```yaml
|
|
media_storage_providers:
|
|
- module: file_system
|
|
store_local: false
|
|
store_remote: false
|
|
store_synchronous: false
|
|
config:
|
|
directory: /mnt/some/other/directory
|
|
```
|
|
---
|
|
### `max_upload_size`
|
|
|
|
The largest allowed upload size in bytes.
|
|
|
|
If you are using a reverse proxy you may also need to set this value in
|
|
your reverse proxy's config. Defaults to 50M. Notably Nginx has a small max body size by default.
|
|
See [here](../../reverse_proxy.md) for more on using a reverse proxy with Synapse.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_upload_size: 60M
|
|
```
|
|
---
|
|
### `max_image_pixels`
|
|
|
|
Maximum number of pixels that will be thumbnailed. Defaults to 32M.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_image_pixels: 35M
|
|
```
|
|
---
|
|
### `remote_media_download_burst_count`
|
|
|
|
Remote media downloads are ratelimited using a [leaky bucket algorithm](https://en.wikipedia.org/wiki/Leaky_bucket), where a given "bucket" is keyed to the IP address of the requester when requesting remote media downloads. This configuration option sets the size of the bucket against which the size in bytes of downloads are penalized - if the bucket is full, ie a given number of bytes have already been downloaded, further downloads will be denied until the bucket drains. Defaults to 500MiB. See also `remote_media_download_per_second` which determines the rate at which the "bucket" is emptied and thus has available space to authorize new requests.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
remote_media_download_burst_count: 200M
|
|
```
|
|
---
|
|
### `remote_media_download_per_second`
|
|
|
|
Works in conjunction with `remote_media_download_burst_count` to ratelimit remote media downloads - this configuration option determines the rate at which the "bucket" (see above) leaks in bytes per second. As requests are made to download remote media, the size of those requests in bytes is added to the bucket, and once the bucket has reached it's capacity, no more requests will be allowed until a number of bytes has "drained" from the bucket. This setting determines the rate at which bytes drain from the bucket, with the practical effect that the larger the number, the faster the bucket leaks, allowing for more bytes downloaded over a shorter period of time. Defaults to 87KiB per second. See also `remote_media_download_burst_count`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
remote_media_download_per_second: 40K
|
|
```
|
|
---
|
|
### `prevent_media_downloads_from`
|
|
|
|
A list of domains to never download media from. Media from these
|
|
domains that is already downloaded will not be deleted, but will be
|
|
inaccessible to users. This option does not affect admin APIs trying
|
|
to download/operate on media.
|
|
|
|
This will not prevent the listed domains from accessing media themselves.
|
|
It simply prevents users on this server from downloading media originating
|
|
from the listed servers.
|
|
|
|
This will have no effect on media originating from the local server. This only
|
|
affects media downloaded from other Matrix servers, to control URL previews see
|
|
[`url_preview_ip_range_blacklist`](#url_preview_ip_range_blacklist) or
|
|
[`url_preview_url_blacklist`](#url_preview_url_blacklist).
|
|
|
|
Defaults to an empty list (nothing blocked).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
prevent_media_downloads_from:
|
|
- evil.example.org
|
|
- evil2.example.org
|
|
```

|
### `dynamic_thumbnails`
|
|
|
|
Whether to generate new thumbnails on the fly to precisely match
|
|
the resolution requested by the client. If true then whenever
|
|
a new resolution is requested by the client the server will
|
|
generate a new thumbnail. If false the server will pick a thumbnail
|
|
from a precalculated list. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
dynamic_thumbnails: true
|
|
```
|
|
---
|
|
### `thumbnail_sizes`
|
|
|
|
List of thumbnails to precalculate when an image is uploaded. Associated sub-options are:
|
|
* `width`
|
|
* `height`
|
|
* `method`: i.e. `crop`, `scale`, etc.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
thumbnail_sizes:
|
|
- width: 32
|
|
height: 32
|
|
method: crop
|
|
- width: 96
|
|
height: 96
|
|
method: crop
|
|
- width: 320
|
|
height: 240
|
|
method: scale
|
|
- width: 640
|
|
height: 480
|
|
method: scale
|
|
- width: 800
|
|
height: 600
|
|
method: scale
|
|
```
|

|
|
### `media_retention`
|
|
|
|
Controls whether local media and entries in the remote media cache
|
|
(media that is downloaded from other homeservers) should be removed
|
|
under certain conditions, typically for the purpose of saving space.
|
|
|
|
Purging media files will be the carried out by the media worker
|
|
(that is, the worker that has the `enable_media_repo` homeserver config
|
|
option set to 'true'). This may be the main process.
|
|
|
|
The `media_retention.local_media_lifetime` and
|
|
`media_retention.remote_media_lifetime` config options control whether
|
|
media will be purged if it has not been accessed in a given amount of
|
|
time. Note that media is 'accessed' when loaded in a room in a client, or
|
|
otherwise downloaded by a local or remote user. If the media has never
|
|
been accessed, the media's creation time is used instead. Both thumbnails
|
|
and the original media will be removed. If either of these options are unset,
|
|
then media of that type will not be purged.
|
|
|
|
Local or cached remote media that has been
|
|
[quarantined](../../admin_api/media_admin_api.md#quarantining-media-in-a-room)
|
|
will not be deleted. Similarly, local media that has been marked as
|
|
[protected from quarantine](../../admin_api/media_admin_api.md#protecting-media-from-being-quarantined)
|
|
will not be deleted.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
media_retention:
|
|
local_media_lifetime: 90d
|
|
remote_media_lifetime: 14d
|
|
```
|

|
|
### `url_preview_enabled`
|
|
|
|
This setting determines whether the preview URL API is enabled.
|
|
It is disabled by default. Set to true to enable. If enabled you must specify a
|
|
`url_preview_ip_range_blacklist` blacklist.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
url_preview_enabled: true
|
|
```
|
|
---
|
|
### `url_preview_ip_range_blacklist`
|
|
|
|
List of IP address CIDR ranges that the URL preview spider is denied
|
|
from accessing. There are no defaults: you must explicitly
|
|
specify a list for URL previewing to work. You should specify any
|
|
internal services in your network that you do not want synapse to try
|
|
to connect to, otherwise anyone in any Matrix room could cause your
|
|
synapse to issue arbitrary GET requests to your internal services,
|
|
causing serious security issues.
|
|
|
|
(0.0.0.0 and :: are always blacklisted, whether or not they are explicitly
|
|
listed here, since they correspond to unroutable addresses.)
|
|
|
|
This must be specified if `url_preview_enabled` is set. It is recommended that
|
|
you use the following example list as a starting point.
|
|
|
|
Note: The value is ignored when an HTTP proxy is in use.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
url_preview_ip_range_blacklist:
|
|
- '127.0.0.0/8'
|
|
- '10.0.0.0/8'
|
|
- '172.16.0.0/12'
|
|
- '192.168.0.0/16'
|
|
- '100.64.0.0/10'
|
|
- '192.0.0.0/24'
|
|
- '169.254.0.0/16'
|
|
- '192.88.99.0/24'
|
|
- '198.18.0.0/15'
|
|
- '192.0.2.0/24'
|
|
- '198.51.100.0/24'
|
|
- '203.0.113.0/24'
|
|
- '224.0.0.0/4'
|
|
- '::1/128'
|
|
- 'fe80::/10'
|
|
- 'fc00::/7'
|
|
- '2001:db8::/32'
|
|
- 'ff00::/8'
|
|
- 'fec0::/10'
|
|
```
|
|
---
|
|
### `url_preview_ip_range_whitelist`
|
|
|
|
This option sets a list of IP address CIDR ranges that the URL preview spider is allowed
|
|
to access even if they are specified in `url_preview_ip_range_blacklist`.
|
|
This is useful for specifying exceptions to wide-ranging blacklisted
|
|
target IP ranges - e.g. for enabling URL previews for a specific private
|
|
website only visible in your network. Defaults to none.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
url_preview_ip_range_whitelist:
|
|
- '192.168.1.1'
|
|
```
|
|
---
|
|
### `url_preview_url_blacklist`
|
|
|
|
Optional list of URL matches that the URL preview spider is denied from
|
|
accessing. This is a usability feature, not a security one. You should use
|
|
`url_preview_ip_range_blacklist` in preference to this, otherwise someone could
|
|
define a public DNS entry that points to a private IP address and circumvent
|
|
the blacklist. Applications that perform redirects or serve different content
|
|
when detecting that Synapse is accessing them can also bypass the blacklist.
|
|
This is more useful if you know there is an entire shape of URL that you know
|
|
that you do not want Synapse to preview.
|
|
|
|
Each list entry is a dictionary of url component attributes as returned
|
|
by urlparse.urlsplit as applied to the absolute form of the URL. See
|
|
[here](https://docs.python.org/2/library/urlparse.html#urlparse.urlsplit) for more
|
|
information. Some examples are:
|
|
|
|
* `username`
|
|
* `netloc`
|
|
* `scheme`
|
|
* `path`
|
|
|
|
The values of the dictionary are treated as a filename match pattern
|
|
applied to that component of URLs, unless they start with a ^ in which
|
|
case they are treated as a regular expression match. If all the
|
|
specified component matches for a given list item succeed, the URL is
|
|
blacklisted.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
url_preview_url_blacklist:
|
|
# blacklist any URL with a username in its URI
|
|
- username: '*'
|
|
|
|
# blacklist all *.google.com URLs
|
|
- netloc: 'google.com'
|
|
- netloc: '*.google.com'
|
|
|
|
# blacklist all plain HTTP URLs
|
|
- scheme: 'http'
|
|
|
|
# blacklist http(s)://www.acme.com/foo
|
|
- netloc: 'www.acme.com'
|
|
path: '/foo'
|
|
|
|
# blacklist any URL with a literal IPv4 address
|
|
- netloc: '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$'
|
|
```
|
|
---
|
|
### `max_spider_size`
|
|
|
|
The largest allowed URL preview spidering size in bytes. Defaults to 10M.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
max_spider_size: 8M
|
|
```
|
|
---
|
|
### `url_preview_accept_language`
|
|
|
|
A list of values for the Accept-Language HTTP header used when
|
|
downloading webpages during URL preview generation. This allows
|
|
Synapse to specify the preferred languages that URL previews should
|
|
be in when communicating with remote servers.
|
|
|
|
Each value is a IETF language tag; a 2-3 letter identifier for a
|
|
language, optionally followed by subtags separated by '-', specifying
|
|
a country or region variant.
|
|
|
|
Multiple values can be provided, and a weight can be added to each by
|
|
using quality value syntax (;q=). '*' translates to any language.
|
|
|
|
Defaults to "en".
|
|
|
|
Example configuration:
|
|
```yaml
|
|
url_preview_accept_language:
|
|
- 'en-UK'
|
|
- 'en-US;q=0.9'
|
|
- 'fr;q=0.8'
|
|
- '*;q=0.7'
|
|
```
|
|
---
|
|
### `oembed`
|
|
|
|
oEmbed allows for easier embedding content from a website. It can be
|
|
used for generating URLs previews of services which support it. A default list of oEmbed providers
|
|
is included with Synapse. Set `disable_default_providers` to true to disable using
|
|
these default oEmbed URLs. Use `additional_providers` to specify additional files with oEmbed configuration (each
|
|
should be in the form of providers.json). By default this list is empty.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
oembed:
|
|
disable_default_providers: true
|
|
additional_providers:
|
|
- oembed/my_providers.json
|
|
```
|

|
|
## Captcha
|
|
|
|
See [here](../../CAPTCHA_SETUP.md) for full details on setting up captcha.
|
|
|
|
---
|
|
### `recaptcha_public_key`
|
|
|
|
This homeserver's ReCAPTCHA public key. Must be specified if
|
|
[`enable_registration_captcha`](#enable_registration_captcha) is enabled.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
recaptcha_public_key: "YOUR_PUBLIC_KEY"
|
|
```
|
|
---
|
|
### `recaptcha_private_key`
|
|
|
|
This homeserver's ReCAPTCHA private key. Must be specified if
|
|
[`enable_registration_captcha`](#enable_registration_captcha) is
|
|
enabled.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
recaptcha_private_key: "YOUR_PRIVATE_KEY"
|
|
```
|
|
---
|
|
### `enable_registration_captcha`
|
|
|
|
Set to `true` to require users to complete a CAPTCHA test when registering an account.
|
|
Requires a valid ReCaptcha public/private key.
|
|
Defaults to `false`.
|
|
|
|
Note that [`enable_registration`](#enable_registration) must also be set to allow account registration.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_registration_captcha: true
|
|
```
|
|
---
|
|
### `recaptcha_siteverify_api`
|
|
|
|
The API endpoint to use for verifying `m.login.recaptcha` responses.
|
|
Defaults to `https://www.recaptcha.net/recaptcha/api/siteverify`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
recaptcha_siteverify_api: "https://my.recaptcha.site"
|
|
```
|
|
---
|
|
## TURN
|
|
Options related to adding a TURN server to Synapse.
|
|
|
|
---
|
|
### `turn_uris`
|
|
|
|
The public URIs of the TURN server to give to clients.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
turn_uris: [turn:example.org]
|
|
```
|
|
---
|
|
### `turn_shared_secret`
|
|
|
|
The shared secret used to compute passwords for the TURN server.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
turn_shared_secret: "YOUR_SHARED_SECRET"
|
|
```
|
|
---
|
|
### `turn_username` and `turn_password`
|
|
|
|
The Username and password if the TURN server needs them and does not use a token.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
turn_username: "TURNSERVER_USERNAME"
|
|
turn_password: "TURNSERVER_PASSWORD"
|
|
```
|
|
---
|
|
### `turn_user_lifetime`
|
|
|
|
How long generated TURN credentials last. Defaults to 1h.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
turn_user_lifetime: 2h
|
|
```
|
|
---
|
|
### `turn_allow_guests`
|
|
|
|
Whether guests should be allowed to use the TURN server. This defaults to true, otherwise
|
|
VoIP will be unreliable for guests. However, it does introduce a slight security risk as
|
|
it allows users to connect to arbitrary endpoints without having first signed up for a valid account (e.g. by passing a CAPTCHA).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
turn_allow_guests: false
|
|
```
|
|
---
|
|
## Registration ##
|
|
|
|
Registration can be rate-limited using the parameters in the [Ratelimiting](#ratelimiting) section of this manual.
|
|
|
|
---
|
|
### `enable_registration`
|
|
|
|
Enable registration for new users. Defaults to `false`.
|
|
|
|
It is highly recommended that if you enable registration, you set one or more
|
|
or the following options, to avoid abuse of your server by "bots":
|
|
|
|
* [`enable_registration_captcha`](#enable_registration_captcha)
|
|
* [`registrations_require_3pid`](#registrations_require_3pid)
|
|
* [`registration_requires_token`](#registration_requires_token)
|
|
|
|
(In order to enable registration without any verification, you must also set
|
|
[`enable_registration_without_verification`](#enable_registration_without_verification).)
|
|
|
|
Note that even if this setting is disabled, new accounts can still be created
|
|
via the admin API if
|
|
[`registration_shared_secret`](#registration_shared_secret) is set.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_registration: true
|
|
```
|
|
---
|
|
### `enable_registration_without_verification`
|
|
|
|
Enable registration without email or captcha verification. Note: this option is *not* recommended,
|
|
as registration without verification is a known vector for spam and abuse. Defaults to `false`. Has no effect
|
|
unless [`enable_registration`](#enable_registration) is also enabled.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_registration_without_verification: true
|
|
```
|
|
---
|
|
### `registrations_require_3pid`
|
|
|
|
If this is set, users must provide all of the specified types of 3PID when registering an account.
|
|
|
|
Note that [`enable_registration`](#enable_registration) must also be set to allow account registration.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
registrations_require_3pid:
|
|
- email
|
|
- msisdn
|
|
```
|
|
---
|
|
### `disable_msisdn_registration`
|
|
|
|
Explicitly disable asking for MSISDNs from the registration
|
|
flow (overrides `registrations_require_3pid` if MSISDNs are set as required).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
disable_msisdn_registration: true
|
|
```
|
|
---
|
|
### `allowed_local_3pids`
|
|
|
|
Mandate that users are only allowed to associate certain formats of
|
|
3PIDs with accounts on this server, as specified by the `medium` and `pattern` sub-options.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allowed_local_3pids:
|
|
- medium: email
|
|
pattern: '^[^@]+@matrix\.org$'
|
|
- medium: email
|
|
pattern: '^[^@]+@vector\.im$'
|
|
- medium: msisdn
|
|
pattern: '\+44'
|
|
```
|
|
---
|
|
### `enable_3pid_lookup`
|
|
|
|
Enable 3PIDs lookup requests to identity servers from this server. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_3pid_lookup: false
|
|
```
|
|
---
|
|
### `registration_requires_token`
|
|
|
|
Require users to submit a token during registration.
|
|
Tokens can be managed using the admin [API](../administration/admin_api/registration_tokens.md).
|
|
Disabling this option will not delete any tokens previously generated.
|
|
Defaults to `false`. Set to `true` to enable.
|
|
|
|
|
|
Note that [`enable_registration`](#enable_registration) must also be set to allow account registration.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
registration_requires_token: true
|
|
```
|
|
---
|
|
### `registration_shared_secret`
|
|
|
|
If set, allows registration of standard or admin accounts by anyone who has the
|
|
shared secret, even if [`enable_registration`](#enable_registration) is not
|
|
set.
|
|
|
|
This is primarily intended for use with the `register_new_matrix_user` script
|
|
(see [Registering a user](../../setup/installation.md#registering-a-user));
|
|
however, the interface is [documented](../../admin_api/register_api.html).
|
|
|
|
See also [`registration_shared_secret_path`](#registration_shared_secret_path).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
registration_shared_secret: <PRIVATE STRING>
|
|
```
|
|
|
|
---
|
|
### `registration_shared_secret_path`
|
|
|
|
An alternative to [`registration_shared_secret`](#registration_shared_secret):
|
|
allows the shared secret to be specified in an external file.
|
|
|
|
The file should be a plain text file, containing only the shared secret.
|
|
|
|
If this file does not exist, Synapse will create a new shared
|
|
secret on startup and store it in this file.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
registration_shared_secret_path: /path/to/secrets/file
|
|
```
|
|
|
|
_Added in Synapse 1.67.0._
|
|
|
|
---
|
|
### `bcrypt_rounds`
|
|
|
|
Set the number of bcrypt rounds used to generate password hash.
|
|
Larger numbers increase the work factor needed to generate the hash.
|
|
The default number is 12 (which equates to 2^12 rounds).
|
|
N.B. that increasing this will exponentially increase the time required
|
|
to register or login - e.g. 24 => 2^24 rounds which will take >20 mins.
|
|
Example configuration:
|
|
```yaml
|
|
bcrypt_rounds: 14
|
|
```
|
|
---
|
|
### `allow_guest_access`
|
|
|
|
Allows users to register as guests without a password/email/etc, and
|
|
participate in rooms hosted on this server which have been made
|
|
accessible to anonymous users. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
allow_guest_access: true
|
|
```
|
|
---
|
|
### `default_identity_server`
|
|
|
|
The identity server which we suggest that clients should use when users log
|
|
in on this server.
|
|
|
|
(By default, no suggestion is made, so it is left up to the client.
|
|
This setting is ignored unless `public_baseurl` is also explicitly set.)
|
|
|
|
Example configuration:
|
|
```yaml
|
|
default_identity_server: https://matrix.org
|
|
```
|
|
---
|
|
### `account_threepid_delegates`
|
|
|
|
Delegate verification of phone numbers to an identity server.
|
|
|
|
When a user wishes to add a phone number to their account, we need to verify that they
|
|
actually own that phone number, which requires sending them a text message (SMS).
|
|
Currently Synapse does not support sending those texts itself and instead delegates the
|
|
task to an identity server. The base URI for the identity server to be used is
|
|
specified by the `account_threepid_delegates.msisdn` option.
|
|
|
|
If this is left unspecified, Synapse will not allow users to add phone numbers to
|
|
their account.
|
|
|
|
(Servers handling the these requests must answer the `/requestToken` endpoints defined
|
|
by the Matrix Identity Service API
|
|
[specification](https://matrix.org/docs/spec/identity_service/latest).)
|
|
|
|
*Deprecated in Synapse 1.64.0*: The `email` option is deprecated.
|
|
|
|
*Removed in Synapse 1.66.0*: The `email` option has been removed.
|
|
If present, Synapse will report a configuration error on startup.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
account_threepid_delegates:
|
|
msisdn: http://localhost:8090 # Delegate SMS sending to this local process
|
|
```
|
|
---
|
|
### `enable_set_displayname`
|
|
|
|
Whether users are allowed to change their displayname after it has
|
|
been initially set. Useful when provisioning users based on the
|
|
contents of a third-party directory.
|
|
|
|
Does not apply to server administrators. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_set_displayname: false
|
|
```
|
|
---
|
|
### `enable_set_avatar_url`
|
|
|
|
Whether users are allowed to change their avatar after it has been
|
|
initially set. Useful when provisioning users based on the contents
|
|
of a third-party directory.
|
|
|
|
Does not apply to server administrators. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_set_avatar_url: false
|
|
```
|
|
---
|
|
### `enable_3pid_changes`
|
|
|
|
Whether users can change the third-party IDs associated with their accounts
|
|
(email address and msisdn).
|
|
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_3pid_changes: false
|
|
```
|
|
---
|
|
### `auto_join_rooms`
|
|
|
|
Users who register on this homeserver will automatically be joined
|
|
to the rooms listed under this option.
|
|
|
|
By default, any room aliases included in this list will be created
|
|
as a publicly joinable room when the first user registers for the
|
|
homeserver. If the room already exists, make certain it is a publicly joinable
|
|
room, i.e. the join rule of the room must be set to 'public'. You can find more options
|
|
relating to auto-joining rooms below.
|
|
|
|
As Spaces are just rooms under the hood, Space aliases may also be
|
|
used.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
auto_join_rooms:
|
|
- "#exampleroom:example.com"
|
|
- "#anotherexampleroom:example.com"
|
|
```
|
|
---
|
|
### `autocreate_auto_join_rooms`
|
|
|
|
Where `auto_join_rooms` are specified, setting this flag ensures that
|
|
the rooms exist by creating them when the first user on the
|
|
homeserver registers. This option will not create Spaces.
|
|
|
|
By default the auto-created rooms are publicly joinable from any federated
|
|
server. Use the `autocreate_auto_join_rooms_federated` and
|
|
`autocreate_auto_join_room_preset` settings to customise this behaviour.
|
|
|
|
Setting to false means that if the rooms are not manually created,
|
|
users cannot be auto-joined since they do not exist.
|
|
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
autocreate_auto_join_rooms: false
|
|
```
|
|
---
|
|
### `autocreate_auto_join_rooms_federated`
|
|
|
|
Whether the rooms listed in `auto_join_rooms` that are auto-created are available
|
|
via federation. Only has an effect if `autocreate_auto_join_rooms` is true.
|
|
|
|
Note that whether a room is federated cannot be modified after
|
|
creation.
|
|
|
|
Defaults to true: the room will be joinable from other servers.
|
|
Set to false to prevent users from other homeservers from
|
|
joining these rooms.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
autocreate_auto_join_rooms_federated: false
|
|
```
|
|
---
|
|
### `autocreate_auto_join_room_preset`
|
|
|
|
The room preset to use when auto-creating one of `auto_join_rooms`. Only has an
|
|
effect if `autocreate_auto_join_rooms` is true.
|
|
|
|
Possible values for this option are:
|
|
* "public_chat": the room is joinable by anyone, including
|
|
federated servers if `autocreate_auto_join_rooms_federated` is true (the default).
|
|
* "private_chat": an invitation is required to join these rooms.
|
|
* "trusted_private_chat": an invitation is required to join this room and the invitee is
|
|
assigned a power level of 100 upon joining the room.
|
|
|
|
Each preset will set up a room in the same manner as if it were provided as the `preset` parameter when
|
|
calling the
|
|
[`POST /_matrix/client/v3/createRoom`](https://spec.matrix.org/latest/client-server-api/#post_matrixclientv3createroom)
|
|
Client-Server API endpoint.
|
|
|
|
If a value of "private_chat" or "trusted_private_chat" is used then
|
|
`auto_join_mxid_localpart` must also be configured.
|
|
|
|
Defaults to "public_chat".
|
|
|
|
Example configuration:
|
|
```yaml
|
|
autocreate_auto_join_room_preset: private_chat
|
|
```
|
|
---
|
|
### `auto_join_mxid_localpart`
|
|
|
|
The local part of the user id which is used to create `auto_join_rooms` if
|
|
`autocreate_auto_join_rooms` is true. If this is not provided then the
|
|
initial user account that registers will be used to create the rooms.
|
|
|
|
The user id is also used to invite new users to any auto-join rooms which
|
|
are set to invite-only.
|
|
|
|
It *must* be configured if `autocreate_auto_join_room_preset` is set to
|
|
"private_chat" or "trusted_private_chat".
|
|
|
|
Note that this must be specified in order for new users to be correctly
|
|
invited to any auto-join rooms which have been set to invite-only (either
|
|
at the time of creation or subsequently).
|
|
|
|
Note that, if the room already exists, this user must be joined and
|
|
have the appropriate permissions to invite new members.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
auto_join_mxid_localpart: system
|
|
```
|
|
---
|
|
### `auto_join_rooms_for_guests`
|
|
|
|
When `auto_join_rooms` is specified, setting this flag to false prevents
|
|
guest accounts from being automatically joined to the rooms.
|
|
|
|
Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
auto_join_rooms_for_guests: false
|
|
```
|
|
---
|
|
### `inhibit_user_in_use_error`
|
|
|
|
Whether to inhibit errors raised when registering a new account if the user ID
|
|
already exists. If turned on, requests to `/register/available` will always
|
|
show a user ID as available, and Synapse won't raise an error when starting
|
|
a registration with a user ID that already exists. However, Synapse will still
|
|
raise an error if the registration completes and the username conflicts.
|
|
|
|
Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
inhibit_user_in_use_error: true
|
|
```
|
|
---
|
|
## User session management
|
|
---
|
|
### `session_lifetime`
|
|
|
|
Time that a user's session remains valid for, after they log in.
|
|
|
|
Note that this is not currently compatible with guest logins.
|
|
|
|
Note also that this is calculated at login time: changes are not applied retrospectively to users who have already
|
|
logged in.
|
|
|
|
By default, this is infinite.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
session_lifetime: 24h
|
|
```
|
|
---
|
|
### `refreshable_access_token_lifetime`
|
|
|
|
Time that an access token remains valid for, if the session is using refresh tokens.
|
|
|
|
For more information about refresh tokens, please see the [manual](user_authentication/refresh_tokens.md).
|
|
|
|
Note that this only applies to clients which advertise support for refresh tokens.
|
|
|
|
Note also that this is calculated at login time and refresh time: changes are not applied to
|
|
existing sessions until they are refreshed.
|
|
|
|
By default, this is 5 minutes.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
refreshable_access_token_lifetime: 10m
|
|
```
|
|
---
|
|
### `refresh_token_lifetime`
|
|
|
|
Time that a refresh token remains valid for (provided that it is not
|
|
exchanged for another one first).
|
|
This option can be used to automatically log-out inactive sessions.
|
|
Please see the manual for more information.
|
|
|
|
Note also that this is calculated at login time and refresh time:
|
|
changes are not applied to existing sessions until they are refreshed.
|
|
|
|
By default, this is infinite.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
refresh_token_lifetime: 24h
|
|
```
|
|
---
|
|
### `nonrefreshable_access_token_lifetime`
|
|
|
|
Time that an access token remains valid for, if the session is NOT
|
|
using refresh tokens.
|
|
|
|
Please note that not all clients support refresh tokens, so setting
|
|
this to a short value may be inconvenient for some users who will
|
|
then be logged out frequently.
|
|
|
|
Note also that this is calculated at login time: changes are not applied
|
|
retrospectively to existing sessions for users that have already logged in.
|
|
|
|
By default, this is infinite.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
nonrefreshable_access_token_lifetime: 24h
|
|
```
|
|
---
|
|
### `ui_auth`
|
|
|
|
The amount of time to allow a user-interactive authentication session to be active.
|
|
|
|
This defaults to 0, meaning the user is queried for their credentials
|
|
before every action, but this can be overridden to allow a single
|
|
validation to be re-used. This weakens the protections afforded by
|
|
the user-interactive authentication process, by allowing for multiple
|
|
(and potentially different) operations to use the same validation session.
|
|
|
|
This is ignored for potentially "dangerous" operations (including
|
|
deactivating an account, modifying an account password, adding a 3PID,
|
|
and minting additional login tokens).
|
|
|
|
Use the `session_timeout` sub-option here to change the time allowed for credential validation.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
ui_auth:
|
|
session_timeout: "15s"
|
|
```
|
|
---
|
|
### `login_via_existing_session`
|
|
|
|
Matrix supports the ability of an existing session to mint a login token for
|
|
another client.
|
|
|
|
Synapse disables this by default as it has security ramifications -- a malicious
|
|
client could use the mechanism to spawn more than one session.
|
|
|
|
The duration of time the generated token is valid for can be configured with the
|
|
`token_timeout` sub-option.
|
|
|
|
User-interactive authentication is required when this is enabled unless the
|
|
`require_ui_auth` sub-option is set to `False`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
login_via_existing_session:
|
|
enabled: true
|
|
require_ui_auth: false
|
|
token_timeout: "5m"
|
|
```
|
|
---
|
|
## Metrics
|
|
Config options related to metrics.
|
|
|
|
---
|
|
### `enable_metrics`
|
|
|
|
Set to true to enable collection and rendering of performance metrics.
|
|
Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_metrics: true
|
|
```
|
|
---
|
|
### `sentry`
|
|
|
|
Use this option to enable sentry integration. Provide the DSN assigned to you by sentry
|
|
with the `dsn` setting.
|
|
|
|
An optional `environment` field can be used to specify an environment. This allows
|
|
for log maintenance based on different environments, ensuring better organization
|
|
and analysis..
|
|
|
|
NOTE: While attempts are made to ensure that the logs don't contain
|
|
any sensitive information, this cannot be guaranteed. By enabling
|
|
this option the sentry server may therefore receive sensitive
|
|
information, and it in turn may then disseminate sensitive information
|
|
through insecure notification channels if so configured.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
sentry:
|
|
environment: "production"
|
|
dsn: "..."
|
|
```
|
|
---
|
|
### `metrics_flags`
|
|
|
|
Flags to enable Prometheus metrics which are not suitable to be
|
|
enabled by default, either for performance reasons or limited use.
|
|
Currently the only option is `known_servers`, which publishes
|
|
`synapse_federation_known_servers`, a gauge of the number of
|
|
servers this homeserver knows about, including itself. May cause
|
|
performance problems on large homeservers.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
metrics_flags:
|
|
known_servers: true
|
|
```
|
|
---
|
|
### `report_stats`
|
|
|
|
Whether or not to report homeserver usage statistics. This is originally
|
|
set when generating the config. Set this option to true or false to change the current
|
|
behavior. See
|
|
[Reporting Homeserver Usage Statistics](../administration/monitoring/reporting_homeserver_usage_statistics.md)
|
|
for information on what data is reported.
|
|
|
|
Statistics will be reported 5 minutes after Synapse starts, and then every 3 hours
|
|
after that.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
report_stats: true
|
|
```
|
|
---
|
|
### `report_stats_endpoint`
|
|
|
|
The endpoint to report homeserver usage statistics to.
|
|
Defaults to https://matrix.org/report-usage-stats/push
|
|
|
|
Example configuration:
|
|
```yaml
|
|
report_stats_endpoint: https://example.com/report-usage-stats/push
|
|
```
|
|
---
|
|
## API Configuration
|
|
Config settings related to the client/server API
|
|
|
|
---
|
|
### `room_prejoin_state`
|
|
|
|
This setting controls the state that is shared with users upon receiving an
|
|
invite to a room, or in reply to a knock on a room. By default, the following
|
|
state events are shared with users:
|
|
|
|
- `m.room.join_rules`
|
|
- `m.room.canonical_alias`
|
|
- `m.room.avatar`
|
|
- `m.room.encryption`
|
|
- `m.room.name`
|
|
- `m.room.create`
|
|
- `m.room.topic`
|
|
|
|
To change the default behavior, use the following sub-options:
|
|
* `disable_default_event_types`: boolean. Set to `true` to disable the above
|
|
defaults. If this is enabled, only the event types listed in
|
|
`additional_event_types` are shared. Defaults to `false`.
|
|
* `additional_event_types`: A list of additional state events to include in the
|
|
events to be shared. By default, this list is empty (so only the default event
|
|
types are shared).
|
|
|
|
Each entry in this list should be either a single string or a list of two
|
|
strings.
|
|
* A standalone string `t` represents all events with type `t` (i.e.
|
|
with no restrictions on state keys).
|
|
* A pair of strings `[t, s]` represents a single event with type `t` and
|
|
state key `s`. The same type can appear in two entries with different state
|
|
keys: in this situation, both state keys are included in prejoin state.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
room_prejoin_state:
|
|
disable_default_event_types: false
|
|
additional_event_types:
|
|
# Share all events of type `org.example.custom.event.typeA`
|
|
- org.example.custom.event.typeA
|
|
# Share only events of type `org.example.custom.event.typeB` whose
|
|
# state_key is "foo"
|
|
- ["org.example.custom.event.typeB", "foo"]
|
|
# Share only events of type `org.example.custom.event.typeC` whose
|
|
# state_key is "bar" or "baz"
|
|
- ["org.example.custom.event.typeC", "bar"]
|
|
- ["org.example.custom.event.typeC", "baz"]
|
|
```
|
|
|
|
*Changed in Synapse 1.74:* admins can filter the events in prejoin state based
|
|
on their state key.
|
|
|
|
---
|
|
### `track_puppeted_user_ips`
|
|
|
|
We record the IP address of clients used to access the API for various
|
|
reasons, including displaying it to the user in the "Where you're signed in"
|
|
dialog.
|
|
|
|
By default, when puppeting another user via the admin API, the client IP
|
|
address is recorded against the user who created the access token (ie, the
|
|
admin user), and *not* the puppeted user.
|
|
|
|
Set this option to true to also record the IP address against the puppeted
|
|
user. (This also means that the puppeted user will count as an "active" user
|
|
for the purpose of monthly active user tracking - see `limit_usage_by_mau` etc
|
|
above.)
|
|
|
|
Example configuration:
|
|
```yaml
|
|
track_puppeted_user_ips: true
|
|
```
|
|
---
|
|
### `app_service_config_files`
|
|
|
|
A list of application service config files to use.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
app_service_config_files:
|
|
- app_service_1.yaml
|
|
- app_service_2.yaml
|
|
```
|
|
---
|
|
### `track_appservice_user_ips`
|
|
|
|
Defaults to false. Set to true to enable tracking of application service IP addresses.
|
|
Implicitly enables MAU tracking for application service users.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
track_appservice_user_ips: true
|
|
```
|
|
---
|
|
### `use_appservice_legacy_authorization`
|
|
|
|
Whether to send the application service access tokens via the `access_token` query parameter
|
|
per older versions of the Matrix specification. Defaults to false. Set to true to enable sending
|
|
access tokens via a query parameter.
|
|
|
|
**Enabling this option is considered insecure and is not recommended. **
|
|
|
|
Example configuration:
|
|
```yaml
|
|
use_appservice_legacy_authorization: true
|
|
```
|
|
|
|
---
|
|
### `macaroon_secret_key`
|
|
|
|
A secret which is used to sign
|
|
- access token for guest users,
|
|
- short-term login token used during SSO logins (OIDC or SAML2) and
|
|
- token used for unsubscribing from email notifications.
|
|
|
|
If none is specified, the `registration_shared_secret` is used, if one is given;
|
|
otherwise, a secret key is derived from the signing key.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
macaroon_secret_key: <PRIVATE STRING>
|
|
```
|
|
---
|
|
### `form_secret`
|
|
|
|
A secret which is used to calculate HMACs for form values, to stop
|
|
falsification of values. Must be specified for the User Consent
|
|
forms to work.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
form_secret: <PRIVATE STRING>
|
|
```
|
|
---
|
|
## Signing Keys
|
|
Config options relating to signing keys
|
|
|
|
---
|
|
### `signing_key_path`
|
|
|
|
Path to the signing key to sign events and federation requests with.
|
|
|
|
*New in Synapse 1.67*: If this file does not exist, Synapse will create a new signing
|
|
key on startup and store it in this file.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
signing_key_path: "CONFDIR/SERVERNAME.signing.key"
|
|
```
|
|
---
|
|
### `old_signing_keys`
|
|
|
|
The keys that the server used to sign messages with but won't use
|
|
to sign new messages. For each key, `key` should be the base64-encoded public key, and
|
|
`expired_ts`should be the time (in milliseconds since the unix epoch) that
|
|
it was last used.
|
|
|
|
It is possible to build an entry from an old `signing.key` file using the
|
|
`export_signing_key` script which is provided with synapse.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
old_signing_keys:
|
|
"ed25519:id": { key: "base64string", expired_ts: 123456789123 }
|
|
```
|
|
---
|
|
### `key_refresh_interval`
|
|
|
|
How long key response published by this server is valid for.
|
|
Used to set the `valid_until_ts` in `/key/v2` APIs.
|
|
Determines how quickly servers will query to check which keys
|
|
are still valid. Defaults to 1d.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
key_refresh_interval: 2d
|
|
```
|
|
---
|
|
### `trusted_key_servers`
|
|
|
|
The trusted servers to download signing keys from.
|
|
|
|
When we need to fetch a signing key, each server is tried in parallel.
|
|
|
|
Normally, the connection to the key server is validated via TLS certificates.
|
|
Additional security can be provided by configuring a `verify key`, which
|
|
will make synapse check that the response is signed by that key.
|
|
|
|
This setting supersedes an older setting named `perspectives`. The old format
|
|
is still supported for backwards-compatibility, but it is deprecated.
|
|
|
|
`trusted_key_servers` defaults to matrix.org, but using it will generate a
|
|
warning on start-up. To suppress this warning, set
|
|
`suppress_key_server_warning` to true.
|
|
|
|
If the use of a trusted key server has to be deactivated, e.g. in a private
|
|
federation or for privacy reasons, this can be realised by setting
|
|
an empty array (`trusted_key_servers: []`). Then Synapse will request the keys
|
|
directly from the server that owns the keys. If Synapse does not get keys directly
|
|
from the server, the events of this server will be rejected.
|
|
|
|
Options for each entry in the list include:
|
|
* `server_name`: the name of the server. Required.
|
|
* `verify_keys`: an optional map from key id to base64-encoded public key.
|
|
If specified, we will check that the response is signed by at least
|
|
one of the given keys.
|
|
* `accept_keys_insecurely`: a boolean. Normally, if `verify_keys` is unset,
|
|
and `federation_verify_certificates` is not `true`, synapse will refuse
|
|
to start, because this would allow anyone who can spoof DNS responses
|
|
to masquerade as the trusted key server. If you know what you are doing
|
|
and are sure that your network environment provides a secure connection
|
|
to the key server, you can set this to `true` to override this behaviour.
|
|
|
|
Example configuration #1:
|
|
```yaml
|
|
trusted_key_servers:
|
|
- server_name: "my_trusted_server.example.com"
|
|
verify_keys:
|
|
"ed25519:auto": "abcdefghijklmnopqrstuvwxyzabcdefghijklmopqr"
|
|
- server_name: "my_other_trusted_server.example.com"
|
|
```
|
|
Example configuration #2:
|
|
```yaml
|
|
trusted_key_servers:
|
|
- server_name: "matrix.org"
|
|
```
|
|
---
|
|
### `suppress_key_server_warning`
|
|
|
|
Set the following to true to disable the warning that is emitted when the
|
|
`trusted_key_servers` include 'matrix.org'. See above.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
suppress_key_server_warning: true
|
|
```
|
|
---
|
|
### `key_server_signing_keys_path`
|
|
|
|
The signing keys to use when acting as a trusted key server. If not specified
|
|
defaults to the server signing key.
|
|
|
|
Can contain multiple keys, one per line.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
key_server_signing_keys_path: "key_server_signing_keys.key"
|
|
```
|
|
---
|
|
## Single sign-on integration
|
|
|
|
The following settings can be used to make Synapse use a single sign-on
|
|
provider for authentication, instead of its internal password database.
|
|
|
|
You will probably also want to set the following options to `false` to
|
|
disable the regular login/registration flows:
|
|
* [`enable_registration`](#enable_registration)
|
|
* [`password_config.enabled`](#password_config)
|
|
|
|
---
|
|
### `saml2_config`
|
|
|
|
Enable SAML2 for registration and login. Uses pysaml2. To learn more about pysaml and
|
|
to find a full list options for configuring pysaml, read the docs [here](https://pysaml2.readthedocs.io/en/latest/).
|
|
|
|
At least one of `sp_config` or `config_path` must be set in this section to
|
|
enable SAML login. You can either put your entire pysaml config inline using the `sp_config`
|
|
option, or you can specify a path to a psyaml config file with the sub-option `config_path`.
|
|
This setting has the following sub-options:
|
|
|
|
* `idp_name`: A user-facing name for this identity provider, which is used to
|
|
offer the user a choice of login mechanisms.
|
|
* `idp_icon`: An optional icon for this identity provider, which is presented
|
|
by clients and Synapse's own IdP picker page. If given, must be an
|
|
MXC URI of the format `mxc://<server-name>/<media-id>`. (An easy way to
|
|
obtain such an MXC URI is to upload an image to an (unencrypted) room
|
|
and then copy the "url" from the source of the event.)
|
|
* `idp_brand`: An optional brand for this identity provider, allowing clients
|
|
to style the login flow according to the identity provider in question.
|
|
See the [spec](https://spec.matrix.org/latest/) for possible options here.
|
|
* `sp_config`: the configuration for the pysaml2 Service Provider. See pysaml2 docs for format of config.
|
|
Default values will be used for the `entityid` and `service` settings,
|
|
so it is not normally necessary to specify them unless you need to
|
|
override them. Here are a few useful sub-options for configuring pysaml:
|
|
* `metadata`: Point this to the IdP's metadata. You must provide either a local
|
|
file via the `local` attribute or (preferably) a URL via the
|
|
`remote` attribute.
|
|
* `accepted_time_diff: 3`: Allowed clock difference in seconds between the homeserver and IdP.
|
|
Defaults to 0.
|
|
* `service`: By default, the user has to go to our login page first. If you'd like
|
|
to allow IdP-initiated login, set `allow_unsolicited` to true under `sp` in the `service`
|
|
section.
|
|
* `config_path`: specify a separate pysaml2 configuration file thusly:
|
|
`config_path: "CONFDIR/sp_conf.py"`
|
|
* `saml_session_lifetime`: The lifetime of a SAML session. This defines how long a user has to
|
|
complete the authentication process, if `allow_unsolicited` is unset. The default is 15 minutes.
|
|
* `user_mapping_provider`: Using this option, an external module can be provided as a
|
|
custom solution to mapping attributes returned from a saml provider onto a matrix user. The
|
|
`user_mapping_provider` has the following attributes:
|
|
* `module`: The custom module's class.
|
|
* `config`: Custom configuration values for the module. Use the values provided in the
|
|
example if you are using the built-in user_mapping_provider, or provide your own
|
|
config values for a custom class if you are using one. This section will be passed as a Python
|
|
dictionary to the module's `parse_config` method. The built-in provider takes the following two
|
|
options:
|
|
* `mxid_source_attribute`: The SAML attribute (after mapping via the attribute maps) to use
|
|
to derive the Matrix ID from. It is 'uid' by default. Note: This used to be configured by the
|
|
`saml2_config.mxid_source_attribute option`. If that is still defined, its value will be used instead.
|
|
* `mxid_mapping`: The mapping system to use for mapping the saml attribute onto a
|
|
matrix ID. Options include: `hexencode` (which maps unpermitted characters to '=xx')
|
|
and `dotreplace` (which replaces unpermitted characters with '.').
|
|
The default is `hexencode`. Note: This used to be configured by the
|
|
`saml2_config.mxid_mapping option`. If that is still defined, its value will be used instead.
|
|
* `grandfathered_mxid_source_attribute`: In previous versions of synapse, the mapping from SAML attribute to
|
|
MXID was always calculated dynamically rather than stored in a table. For backwards- compatibility, we will look for `user_ids`
|
|
matching such a pattern before creating a new account. This setting controls the SAML attribute which will be used for this
|
|
backwards-compatibility lookup. Typically it should be 'uid', but if the attribute maps are changed, it may be necessary to change it.
|
|
The default is 'uid'.
|
|
* `attribute_requirements`: It is possible to configure Synapse to only allow logins if SAML attributes
|
|
match particular values. The requirements can be listed under
|
|
`attribute_requirements` as shown in the example. All of the listed attributes must
|
|
match for the login to be permitted.
|
|
* `idp_entityid`: If the metadata XML contains multiple IdP entities then the `idp_entityid`
|
|
option must be set to the entity to redirect users to.
|
|
Most deployments only have a single IdP entity and so should omit this option.
|
|
|
|
|
|
Once SAML support is enabled, a metadata file will be exposed at
|
|
`https://<server>:<port>/_synapse/client/saml2/metadata.xml`, which you may be able to
|
|
use to configure your SAML IdP with. Alternatively, you can manually configure
|
|
the IdP to use an ACS location of
|
|
`https://<server>:<port>/_synapse/client/saml2/authn_response`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
saml2_config:
|
|
sp_config:
|
|
metadata:
|
|
local: ["saml2/idp.xml"]
|
|
remote:
|
|
- url: https://our_idp/metadata.xml
|
|
accepted_time_diff: 3
|
|
|
|
service:
|
|
sp:
|
|
allow_unsolicited: true
|
|
|
|
# The examples below are just used to generate our metadata xml, and you
|
|
# may well not need them, depending on your setup. Alternatively you
|
|
# may need a whole lot more detail - see the pysaml2 docs!

### `oidc_providers`
|
|
|
|
List of OpenID Connect (OIDC) / OAuth 2.0 identity providers, for registration
|
|
and login. See [here](../../openid.md)
|
|
for information on how to configure these options.
|
|
|
|
For backwards compatibility, it is also possible to configure a single OIDC
|
|
provider via an `oidc_config` setting. This is now deprecated and admins are
|
|
advised to migrate to the `oidc_providers` format. (When doing that migration,
|
|
use `oidc` for the `idp_id` to ensure that existing users continue to be
|
|
recognised.)
|
|
|
|
Options for each entry include:
|
|
* `idp_id`: a unique identifier for this identity provider. Used internally
|
|
by Synapse; should be a single word such as 'github'.
|
|
Note that, if this is changed, users authenticating via that provider
|
|
will no longer be recognised as the same user!
|
|
(Use "oidc" here if you are migrating from an old `oidc_config` configuration.)
|
|
|
|
* `idp_name`: A user-facing name for this identity provider, which is used to
|
|
offer the user a choice of login mechanisms.
|
|
|
|
* `idp_icon`: An optional icon for this identity provider, which is presented
|
|
by clients and Synapse's own IdP picker page. If given, must be an
|
|
MXC URI of the format `mxc://<server-name>/<media-id>`. (An easy way to
|
|
obtain such an MXC URI is to upload an image to an (unencrypted) room
|
|
and then copy the "url" from the source of the event.)
|
|
|
|
* `idp_brand`: An optional brand for this identity provider, allowing clients
|
|
to style the login flow according to the identity provider in question.
|
|
See the [spec](https://spec.matrix.org/latest/) for possible options here.
|
|
|
|
* `discover`: set to false to disable the use of the OIDC discovery mechanism
|
|
to discover endpoints. Defaults to true.
|
|
|
|
* `issuer`: Required. The OIDC issuer. Used to validate tokens and (if discovery
|
|
is enabled) to discover the provider's endpoints.
|
|
|
|
* `client_id`: Required. oauth2 client id to use.
|
|
|
|
* `client_secret`: oauth2 client secret to use. May be omitted if
|
|
`client_secret_jwt_key` is given, or if `client_auth_method` is 'none'.
|
|
Must be omitted if `client_secret_path` is specified.
|
|
|
|
* `client_secret_path`: path to the oauth2 client secret to use. With that
|
|
it's not necessary to leak secrets into the config file itself.
|
|
Mutually exclusive with `client_secret`. Can be omitted if
|
|
`client_secret_jwt_key` is specified.
|
|
|
|
*Added in Synapse 1.91.0.*
|
|
|
|
* `client_secret_jwt_key`: Alternative to client_secret: details of a key used
|
|
to create a JSON Web Token to be used as an OAuth2 client secret. If
|
|
given, must be a dictionary with the following properties:
|
|
|
|
* `key`: a pem-encoded signing key. Must be a suitable key for the
|
|
algorithm specified. Required unless `key_file` is given.
|
|
|
|
* `key_file`: the path to file containing a pem-encoded signing key file.
|
|
Required unless `key` is given.
|
|
|
|
* `jwt_header`: a dictionary giving properties to include in the JWT
|
|
header. Must include the key `alg`, giving the algorithm used to
|
|
sign the JWT, such as "ES256", using the JWA identifiers in
|
|
RFC7518.
|
|
|
|
* `jwt_payload`: an optional dictionary giving properties to include in
|
|
the JWT payload. Normally this should include an `iss` key.
|
|
|
|
* `client_auth_method`: auth method to use when exchanging the token. Valid
|
|
values are `client_secret_basic` (default), `client_secret_post` and
|
|
`none`.
|
|
|
|
* `pkce_method`: Whether to use proof key for code exchange when requesting
|
|
and exchanging the token. Valid values are: `auto`, `always`, or `never`. Defaults
|
|
to `auto`, which uses PKCE if supported during metadata discovery. Set to `always`
|
|
to force enable PKCE or `never` to force disable PKCE.
|
|
|
|
* `scopes`: list of scopes to request. This should normally include the "openid"
|
|
scope. Defaults to `["openid"]`.
|
|
|
|
* `authorization_endpoint`: the oauth2 authorization endpoint. Required if
|
|
provider discovery is disabled.
|
|
|
|
* `token_endpoint`: the oauth2 token endpoint. Required if provider discovery is
|
|
disabled.
|
|
|
|
* `userinfo_endpoint`: the OIDC userinfo endpoint. Required if discovery is
|
|
disabled and the 'openid' scope is not requested.
|
|
|
|
* `jwks_uri`: URI where to fetch the JWKS. Required if discovery is disabled and
|
|
the 'openid' scope is used.
|
|
|
|
* `skip_verification`: set to 'true' to skip metadata verification. Use this if
|
|
you are connecting to a provider that is not OpenID Connect compliant.
|
|
Defaults to false. Avoid this in production.
|
|
|
|
* `user_profile_method`: Whether to fetch the user profile from the userinfo
|
|
endpoint, or to rely on the data returned in the id_token from the `token_endpoint`.
|
|
Valid values are: `auto` or `userinfo_endpoint`.
|
|
Defaults to `auto`, which uses the userinfo endpoint if `openid` is
|
|
not included in `scopes`. Set to `userinfo_endpoint` to always use the
|
|
userinfo endpoint.
|
|
|
|
* `additional_authorization_parameters`: String to string dictionary that will be passed as
|
|
additional parameters to the authorization grant URL.
|
|
|
|
* `allow_existing_users`: set to true to allow a user logging in via OIDC to
|
|
match a pre-existing account instead of failing. This could be used if
|
|
switching from password logins to OIDC. Defaults to false.
|
|
|
|
* `enable_registration`: set to 'false' to disable automatic registration of new
|
|
users. This allows the OIDC SSO flow to be limited to sign in only, rather than
|
|
automatically registering users that have a valid SSO login but do not have
|
|
a pre-registered account. Defaults to true.
|
|
|
|
* `user_mapping_provider`: Configuration for how attributes returned from a OIDC
|
|
provider are mapped onto a matrix user. This setting has the following
|
|
sub-properties:
|
|
|
|
* `module`: The class name of a custom mapping module. Default is
|
|
`synapse.handlers.oidc.JinjaOidcMappingProvider`.
|
|
See [OpenID Mapping Providers](../../sso_mapping_providers.md#openid-mapping-providers)
|
|
for information on implementing a custom mapping provider.
|
|
|
|
* `config`: Configuration for the mapping provider module. This section will
|
|
be passed as a Python dictionary to the user mapping provider
|
|
module's `parse_config` method.
|
|
|
|
For the default provider, the following settings are available:
|
|
|
|
* `subject_template`: Jinja2 template for a unique identifier for the user.
|
|
Defaults to `{{ user.sub }}`, which OpenID Connect compliant providers should provide.
|
|
|
|
This replaces and overrides `subject_claim`.
|
|
|
|
* `subject_claim`: name of the claim containing a unique identifier
|
|
for the user. Defaults to 'sub', which OpenID Connect
|
|
compliant providers should provide.
|
|
|
|
*Deprecated in Synapse v1.75.0.*
|
|
|
|
* `picture_template`: Jinja2 template for an url for the user's profile picture.
|
|
Defaults to `{{ user.picture }}`, which OpenID Connect compliant providers should
|
|
provide and has to refer to a direct image file such as PNG, JPEG, or GIF image file.
|
|
|
|
This replaces and overrides `picture_claim`.
|
|
|
|
Currently only supported in monolithic (single-process) server configurations
|
|
where the media repository runs within the Synapse process.
|
|
|
|
* `picture_claim`: name of the claim containing an url for the user's profile picture.
|
|
Defaults to 'picture', which OpenID Connect compliant providers should provide
|
|
and has to refer to a direct image file such as PNG, JPEG, or GIF image file.
|
|
|
|
Currently only supported in monolithic (single-process) server configurations
|
|
where the media repository runs within the Synapse process.
|
|
|
|
*Deprecated in Synapse v1.75.0.*
|
|
|
|
* `localpart_template`: Jinja2 template for the localpart of the MXID.
|
|
If this is not set, the user will be prompted to choose their
|
|
own username (see the documentation for the `sso_auth_account_details.html`
|
|
template). This template can use the `localpart_from_email` filter.
|
|
|
|
* `confirm_localpart`: Whether to prompt the user to validate (or
|
|
change) the generated localpart (see the documentation for the
|
|
'sso_auth_account_details.html' template), instead of
|
|
registering the account right away.
|
|
|
|
* `display_name_template`: Jinja2 template for the display name to set
|
|
on first login. If unset, no displayname will be set.
|
|
|
|
* `email_template`: Jinja2 template for the email address of the user.
|
|
If unset, no email address will be added to the account.
|
|
|
|
* `extra_attributes`: a map of Jinja2 templates for extra attributes
|
|
to send back to the client during login. Note that these are non-standard and clients will ignore them
|
|
without modifications.
|
|
|
|
When rendering, the Jinja2 templates are given a 'user' variable,
|
|
which is set to the claims returned by the UserInfo Endpoint and/or
|
|
in the ID Token.
|
|
|
|
* `backchannel_logout_enabled`: set to `true` to process OIDC Back-Channel Logout notifications.
|
|
Those notifications are expected to be received on `/_synapse/client/oidc/backchannel_logout`.
|
|
Defaults to `false`.
|
|
|
|
* `backchannel_logout_ignore_sub`: by default, the OIDC Back-Channel Logout feature checks that the
|
|
`sub` claim matches the subject claim received during login. This check can be disabled by setting
|
|
this to `true`. Defaults to `false`.
|
|
|
|
You might want to disable this if the `subject_claim` returned by the mapping provider is not `sub`.
|
|
|
|
It is possible to configure Synapse to only allow logins if certain attributes
|
|
match particular values in the OIDC userinfo. The requirements can be listed under
|
|
`attribute_requirements` as shown here:
|
|
```yaml
|
|
attribute_requirements:
|
|
- attribute: family_name
|
|
value: "Stephensson"
|
|
- attribute: groups
|
|
value: "admin"
|
|
```
|
|
All of the listed attributes must match for the login to be permitted. Additional attributes can be added to
|
|
userinfo by expanding the `scopes` section of the OIDC config to retrieve
|
|
additional information from the OIDC provider.
|
|
|
|
If the OIDC claim is a list, then the attribute must match any value in the list.
|
|
Otherwise, it must exactly match the value of the claim. Using the example
|
|
above, the `family_name` claim MUST be "Stephensson", but the `groups`
|
|
claim MUST contain "admin".
|
|
|
|

|
|
```yaml
|
|

|
|
* `enabled`: Set this to true to enable authorization against a CAS server.
|
|
Defaults to false.
|
|
* `idp_name`: A user-facing name for this identity provider, which is used to
|
|
offer the user a choice of login mechanisms.
|
|
* `idp_icon`: An optional icon for this identity provider, which is presented
|
|
by clients and Synapse's own IdP picker page. If given, must be an
|
|
MXC URI of the format `mxc://<server-name>/<media-id>`. (An easy way to
|
|
obtain such an MXC URI is to upload an image to an (unencrypted) room
|
|
and then copy the "url" from the source of the event.)
|
|
* `idp_brand`: An optional brand for this identity provider, allowing clients
|
|
to style the login flow according to the identity provider in question.
|
|
See the [spec](https://spec.matrix.org/latest/) for possible options here.
|
|
* `server_url`: The URL of the CAS authorization endpoint.
|
|
* `protocol_version`: The CAS protocol version, defaults to none (version 3 is required if you want to use "required_attributes").
|
|
* `displayname_attribute`: The attribute of the CAS response to use as the display name.
|
|
If no name is given here, no displayname will be set.
|
|
* `required_attributes`: It is possible to configure Synapse to only allow logins if CAS attributes
|
|
match particular values. All of the keys given below must exist
|
|
and the values must match the given value. Alternately if the given value
|
|
is `None` then any value is allowed (the attribute just must exist).
|
|
All of the listed attributes must match for the login to be permitted.
|
|
* `enable_registration`: set to 'false' to disable automatic registration of new
|
|
users. This allows the CAS SSO flow to be limited to sign in only, rather than
|
|
automatically registering users that have a valid SSO login but do not have
|
|
a pre-registered account. Defaults to true.
|
|
* `allow_numeric_ids`: set to 'true' allow numeric user IDs (default false).
|
|
This allows CAS SSO flow to provide user IDs composed of numbers only.
|
|
These identifiers will be prefixed by the letter "u" by default.
|
|
The prefix can be configured using the "numeric_ids_prefix" option.
|
|
Be careful to choose the prefix correctly to avoid any possible conflicts
|
|
(e.g. user 1234 becomes u1234 when a user u1234 already exists).
|
|
* `numeric_ids_prefix`: the prefix you wish to add in front of a numeric user ID
|
|
when the "allow_numeric_ids" option is set to "true".
|
|
By default, the prefix is the letter "u" and only alphanumeric characters are allowed.
|
|
|
|
*Added in Synapse 1.93.0.*
|
|
|
|
Example configuration:
|
|
```yaml
|
|
cas_config:
|
|
enabled: true
|
|
server_url: "https://cas-server.com"
|
|
protocol_version: 3
|
|
displayname_attribute: name
|
|
required_attributes:
|
|
userGroup: "staff"
|
|
department: None
|
|
enable_registration: true
|
|
allow_numeric_ids: true
|
|
numeric_ids_prefix: "numericuser"
|
|
```
|

|
### `sso`
|
|
|
|
Additional settings to use with single-sign on systems such as OpenID Connect,
|
|
SAML2 and CAS.
|
|
|
|
Server admins can configure custom templates for pages related to SSO. See
|
|
[here](../../templates.md) for more information.
|
|
|
|
Options include:
|
|
* `client_whitelist`: A list of client URLs which are whitelisted so that the user does not
|
|
have to confirm giving access to their account to the URL. Any client
|
|
whose URL starts with an entry in the following list will not be subject
|
|
to an additional confirmation step after the SSO login is completed.
|
|
WARNING: An entry such as "https://my.client" is insecure, because it
|
|
will also match "https://my.client.evil.site", exposing your users to
|
|
phishing attacks from evil.site. To avoid this, include a slash after the
|
|
hostname: "https://my.client/".
|
|
The login fallback page (used by clients that don't natively support the
|
|
required login flows) is whitelisted in addition to any URLs in this list.
|
|
By default, this list contains only the login fallback page.
|
|
* `update_profile_information`: Use this setting to keep a user's profile fields in sync with information from
|
|
the identity provider. Currently only syncing the displayname is supported. Fields
|
|
are checked on every SSO login, and are updated if necessary.
|
|
Note that enabling this option will override user profile information,
|
|
regardless of whether users have opted-out of syncing that
|
|
information when first signing in. Defaults to false.
|
|
|
|
|
|
Example configuration:
|
|
```yaml
|
|
sso:
|
|
client_whitelist:
|
|
- https://riot.im/develop
|
|
- https://my.custom.client/
|
|
update_profile_information: true
|
|
```
|
|
---
|
|
### `jwt_config`
|
|
|
|
JSON web token integration. The following settings can be used to make
|
|
Synapse JSON web tokens for authentication, instead of its internal
|
|
password database.
|
|
|
|
Each JSON Web Token needs to contain a "sub" (subject) claim, which is
|
|
used as the localpart of the mxid.
|
|
|
|
Additionally, the expiration time ("exp"), not before time ("nbf"),
|
|
and issued at ("iat") claims are validated if present.
|
|
|
|
Note that this is a non-standard login type and client support is
|
|
expected to be non-existent.
|
|
|
|
See [here](../../jwt.md) for more.
|
|
|
|
Additional sub-options for this setting include:
|
|
* `enabled`: Set to true to enable authorization using JSON web
|
|
tokens. Defaults to false.
|
|
* `secret`: This is either the private shared secret or the public key used to
|
|
decode the contents of the JSON web token. Required if `enabled` is set to true.
|
|
* `algorithm`: The algorithm used to sign (or HMAC) the JSON web token.
|
|
Supported algorithms are listed
|
|
[here (section JWS)](https://docs.authlib.org/en/latest/specs/rfc7518.html).
|
|
Required if `enabled` is set to true.
|
|
* `subject_claim`: Name of the claim containing a unique identifier for the user.
|
|
Optional, defaults to `sub`.
|
|
* `issuer`: The issuer to validate the "iss" claim against. Optional. If provided the
|
|
"iss" claim will be required and validated for all JSON web tokens.
|
|
* `audiences`: A list of audiences to validate the "aud" claim against. Optional.
|
|
If provided the "aud" claim will be required and validated for all JSON web tokens.
|
|
Note that if the "aud" claim is included in a JSON web token then
|
|
validation will fail without configuring audiences.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
jwt_config:
|
|
enabled: true
|
|
secret: "provided-by-your-issuer"
|
|
algorithm: "provided-by-your-issuer"
|
|
subject_claim: "name_of_claim"
|
|
issuer: "provided-by-your-issuer"
|
|
audiences:
|
|
- "provided-by-your-issuer"
|
|
```
|
|

|
|
### `password_config`
|
|
|
|
Use this setting to enable password-based logins.
|
|
|
|
This setting has the following sub-options:
|
|
* `enabled`: Defaults to true.
|
|
Set to false to disable password authentication.
|
|
Set to `only_for_reauth` to allow users with existing passwords to use them
|
|
to reauthenticate (not log in), whilst preventing new users from setting passwords.
|
|
* `localdb_enabled`: Set to false to disable authentication against the local password
|
|
database. This is ignored if `enabled` is false, and is only useful
|
|
if you have other `password_providers`. Defaults to true.
|
|
* `pepper`: Set the value here to a secret random string for extra security.
|
|
DO NOT CHANGE THIS AFTER INITIAL SETUP!
|
|
* `policy`: Define and enforce a password policy, such as minimum lengths for passwords, etc.
|
|
Each parameter is optional. This is an implementation of MSC2000. Parameters are as follows:
|
|
* `enabled`: Defaults to false. Set to true to enable.
|
|
* `minimum_length`: Minimum accepted length for a password. Defaults to 0.
|
|
* `require_digit`: Whether a password must contain at least one digit.
|
|
Defaults to false.
|
|
* `require_symbol`: Whether a password must contain at least one symbol.
|
|
A symbol is any character that's not a number or a letter. Defaults to false.
|
|
* `require_lowercase`: Whether a password must contain at least one lowercase letter.
|
|
Defaults to false.
|
|
* `require_uppercase`: Whether a password must contain at least one uppercase letter.
|
|
Defaults to false.
|
|
|
|
|
|
Example configuration:
|
|
```yaml
|
|
password_config:
|
|
enabled: false
|
|
localdb_enabled: false
|
|
pepper: "EVEN_MORE_SECRET"
|
|
|
|
policy:
|
|
enabled: true
|
|
minimum_length: 15
|
|
require_digit: true
|
|
require_symbol: true
|
|
require_lowercase: true
|
|
require_uppercase: true
|
|
```
|

|
|
## Push
|
|
Configuration settings related to push notifications
|
|
|
|
---
|
|
### `push`
|
|
|
|
This setting defines options for push notifications.
|
|
|
|
This option has a number of sub-options. They are as follows:
|
|
* `enabled`: Enables or disables push notification calculation. Note, disabling this will also
|
|
stop unread counts being calculated for rooms. This mode of operation is intended
|
|
for homeservers which may only have bots or appservice users connected, or are otherwise
|
|
not interested in push/unread counters. This is enabled by default.
|
|
* `include_content`: Clients requesting push notifications can either have the body of
|
|
the message sent in the notification poke along with other details
|
|
like the sender, or just the event ID and room ID (`event_id_only`).
|
|
If clients choose the to have the body sent, this option controls whether the
|
|
notification request includes the content of the event (other details
|
|
like the sender are still included). If `event_id_only` is enabled, it
|
|
has no effect.
|
|
For modern android devices the notification content will still appear
|
|
because it is loaded by the app. iPhone, however will send a
|
|
notification saying only that a message arrived and who it came from.
|
|
Defaults to true. Set to false to only include the event ID and room ID in push notification payloads.
|
|
* `group_unread_count_by_room: false`: When a push notification is received, an unread count is also sent.
|
|
This number can either be calculated as the number of unread messages for the user, or the number of *rooms* the
|
|
user has unread messages in. Defaults to true, meaning push clients will see the number of
|
|
rooms with unread messages in them. Set to false to instead send the number
|
|
of unread messages.
|
|
* `jitter_delay`: Delays push notifications by a random amount up to the given
|
|
duration. Useful for mitigating timing attacks. Optional, defaults to no
|
|
delay. _Added in Synapse 1.84.0._
|
|
|
|
Example configuration:
|
|
```yaml
|
|
push:
|
|
enabled: true
|
|
include_content: false
|
|
group_unread_count_by_room: false
|
|
jitter_delay: "10s"
|
|
```
|
|
---
|
|
## Rooms
|
|
Config options relating to rooms.
|
|
|
|
---
|
|
### `encryption_enabled_by_default_for_room_type`
|
|
|
|
Controls whether locally-created rooms should be end-to-end encrypted by
|
|
default.
|
|
|
|
Possible options are "all", "invite", and "off". They are defined as:
|
|
|
|
* "all": any locally-created room
|
|
* "invite": any room created with the `private_chat` or `trusted_private_chat`
|
|
room creation presets
|
|
* "off": this option will take no effect
|
|
|
|
The default value is "off".
|
|
|
|
Note that this option will only affect rooms created after it is set. It
|
|
will also not affect rooms created by other servers.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
encryption_enabled_by_default_for_room_type: invite
|
|
```
|
|
---
|
|
### `user_directory`
|
|
|
|
This setting defines options related to the user directory.
|
|
|
|
This option has the following sub-options:
|
|
* `enabled`: Defines whether users can search the user directory. If false then
|
|
empty responses are returned to all queries. Defaults to true.
|
|
* `search_all_users`: Defines whether to search all users visible to your homeserver at the time the search is performed.
|
|
If set to true, will return all users known to the homeserver matching the search query.
|
|
If false, search results will only contain users
|
|
visible in public rooms and users sharing a room with the requester.
|
|
Defaults to false.
|
|
|
|
NB. If you set this to true, and the last time the user_directory search
|
|
indexes were (re)built was before Synapse 1.44, you'll have to
|
|
rebuild the indexes in order to search through all known users.
|
|
|
|
These indexes are built the first time Synapse starts; admins can
|
|
manually trigger a rebuild via the API following the instructions
|
|
[for running background updates](../administration/admin_api/background_updates.md#run),
|
|
set to true to return search results containing all known users, even if that
|
|
user does not share a room with the requester.
|
|
* `prefer_local_users`: Defines whether to prefer local users in search query results.
|
|
If set to true, local users are more likely to appear above remote users when searching the
|
|
user directory. Defaults to false.
|
|
* `show_locked_users`: Defines whether to show locked users in search query results. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
user_directory:
|
|
enabled: false
|
|
search_all_users: true
|
|
prefer_local_users: true
|
|
show_locked_users: true
|
|
```
|
|
---
|
|
### `user_consent`
|
|
|
|
For detailed instructions on user consent configuration, see [here](../../consent_tracking.md).
|
|
|
|
Parts of this section are required if enabling the `consent` resource under
|
|
[`listeners`](#listeners), in particular `template_dir` and `version`.
|
|
|
|
* `template_dir`: gives the location of the templates for the HTML forms.
|
|
This directory should contain one subdirectory per language (eg, `en`, `fr`),
|
|
and each language directory should contain the policy document (named as
|
|
<version>.html) and a success page (success.html).
|
|
|
|
* `version`: specifies the 'current' version of the policy document. It defines
|
|
the version to be served by the consent resource if there is no 'v'
|
|
parameter.
|
|
|
|
* `server_notice_content`: if enabled, will send a user a "Server Notice"
|
|
asking them to consent to the privacy policy. The [`server_notices` section](#server_notices)
|
|
must also be configured for this to work. Notices will *not* be sent to
|
|
guest users unless `send_server_notice_to_guests` is set to true.
|
|
|
|
* `block_events_error`, if set, will block any attempts to send events
|
|
until the user consents to the privacy policy. The value of the setting is
|
|
used as the text of the error.
|
|
|
|
* `require_at_registration`, if enabled, will add a step to the registration
|
|
process, similar to how captcha works. Users will be required to accept the
|
|
policy before their account is created.
|
|
|
|
* `policy_name` is the display name of the policy users will see when registering
|
|
for an account. Has no effect unless `require_at_registration` is enabled.
|
|
Defaults to "Privacy Policy".
|
|
|
|
Example configuration:
|
|
```yaml
|
|
user_consent:
|
|
template_dir: res/templates/privacy
|
|
version: 1.0
|
|
server_notice_content:
|
|
msgtype: m.text
|
|
body: >-
|
|
To continue using this homeserver you must review and agree to the
|
|
terms and conditions at %(consent_uri)s
|
|
send_server_notice_to_guests: true
|
|
block_events_error: >-
|
|
To continue using this homeserver you must review and agree to the
|
|
terms and conditions at %(consent_uri)s
|
|
require_at_registration: false
|
|
policy_name: Privacy Policy
|
|
```
|
|
---
|
|
### `stats`
|
|
|
|
Settings for local room and user statistics collection. See [here](../../room_and_user_statistics.md)
|
|
for more.
|
|
|
|
* `enabled`: Set to false to disable room and user statistics. Note that doing
|
|
so may cause certain features (such as the room directory) not to work
|
|
correctly. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
stats:
|
|
enabled: false
|
|
```
|
|
---
|
|
### `server_notices`
|
|
|
|
Use this setting to enable a room which can be used to send notices
|
|
from the server to users. It is a special room which users cannot leave; notices
|
|
in the room come from a special "notices" user id.
|
|
|
|
If you use this setting, you *must* define the `system_mxid_localpart`
|
|
sub-setting, which defines the id of the user which will be used to send the
|
|
notices.
|
|
|
|
Sub-options for this setting include:
|
|
* `system_mxid_display_name`: set the display name of the "notices" user
|
|
* `system_mxid_avatar_url`: set the avatar for the "notices" user
|
|
* `room_name`: set the room name of the server notices room
|
|
* `room_avatar_url`: optional string. The room avatar to use for server notice rooms. If set to the empty string `""`, notice rooms will not be given an avatar. Defaults to the empty string. _Added in Synapse 1.99.0._
|
|
* `room_topic`: optional string. The topic to use for server notice rooms. If set to the empty string `""`, notice rooms will not be given a topic. Defaults to the empty string. _Added in Synapse 1.99.0._
|
|
* `auto_join`: boolean. If true, the user will be automatically joined to the room instead of being invited.
|
|
Defaults to false. _Added in Synapse 1.98.0._
|
|
|
|
Note that the name, topic and avatar of existing server notice rooms will only be updated when a new notice event is sent.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
server_notices:
|
|
system_mxid_localpart: notices
|
|
system_mxid_display_name: "Server Notices"
|
|
system_mxid_avatar_url: "mxc://example.com/oumMVlgDnLYFaPVkExemNVVZ"
|
|
room_name: "Server Notices"
|
|
room_avatar_url: "mxc://example.com/oumMVlgDnLYFaPVkExemNVVZ"
|
|
room_topic: "Room used by your server admin to notice you of important information"
|
|
auto_join: true
|
|
```
|
|
---
|
|
### `enable_room_list_search`
|
|
|
|
Set to false to disable searching the public room list. When disabled
|
|
blocks searching local and remote room lists for local and remote
|
|
users by always returning an empty list for all queries. Defaults to true.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
enable_room_list_search: false
|
|
```
|
|
---
|
|
### `alias_creation_rules`
|
|
|
|
The `alias_creation_rules` option allows server admins to prevent unwanted
|
|
alias creation on this server.
|
|
|
|
This setting is an optional list of 0 or more rules. By default, no list is
|
|
provided, meaning that all alias creations are permitted.
|
|
|
|
Otherwise, requests to create aliases are matched against each rule in order.
|
|
The first rule that matches decides if the request is allowed or denied. If no
|
|
rule matches, the request is denied. In particular, this means that configuring
|
|
an empty list of rules will deny every alias creation request.
|
|
|
|
Each rule is a YAML object containing four fields, each of which is an optional string:
|
|
|
|
* `user_id`: a glob pattern that matches against the creator of the alias.
|
|
* `alias`: a glob pattern that matches against the alias being created.
|
|
* `room_id`: a glob pattern that matches against the room ID the alias is being pointed at.
|
|
* `action`: either `allow` or `deny`. What to do with the request if the rule matches. Defaults to `allow`.
|
|
|
|
Each of the glob patterns is optional, defaulting to `*` ("match anything").
|
|
Note that the patterns match against fully qualified IDs, e.g. against
|
|
`@alice:example.com`, `#room:example.com` and `!abcdefghijk:example.com` instead
|
|
of `alice`, `room` and `abcedgghijk`.
|
|
|
|
Example configuration:
|
|
|
|
```yaml
|
|
# No rule list specified. All alias creations are allowed.
|
|
# This is the default behaviour.
|
|
alias_creation_rules:
|
|
```
|
|
|
|
```yaml
|
|
# A list of one rule which allows everything.
|
|
# This has the same effect as the previous example.
|
|
alias_creation_rules:
|
|
- "action": "allow"
|
|
```
|
|
|
|
```yaml
|
|
# An empty list of rules. All alias creations are denied.
|
|
alias_creation_rules: []
|
|
```
|
|
|
|
```yaml
|
|
# A list of one rule which denies everything.
|
|
# This has the same effect as the previous example.
|
|
alias_creation_rules:
|
|
- "action": "deny"
|
|
```
|
|
|
|
```yaml
|
|
# Prevent a specific user from creating aliases.
|
|
# Allow other users to create any alias
|
|
alias_creation_rules:
|
|
- user_id: "@bad_user:example.com"
|
|
action: deny
|
|
|
|
- action: allow
|
|
```
|
|
|
|
```yaml
|
|
# Prevent aliases being created which point to a specific room.
|
|
alias_creation_rules:
|
|
- room_id: "!forbiddenRoom:example.com"
|
|
action: deny
|
|
|
|
- action: allow
|
|
```
|
|
|
|
---
|
|
### `room_list_publication_rules`
|
|
|
|
The `room_list_publication_rules` option allows server admins to prevent
|
|
unwanted entries from being published in the public room list.
|
|
|
|
The format of this option is the same as that for
|
|
[`alias_creation_rules`](#alias_creation_rules): an optional list of 0 or more
|
|
rules. By default, no list is provided, meaning that all rooms may be
|
|
published to the room list.
|
|
|
|
Otherwise, requests to publish a room are matched against each rule in order.
|
|
The first rule that matches decides if the request is allowed or denied. If no
|
|
rule matches, the request is denied. In particular, this means that configuring
|
|
an empty list of rules will deny every alias creation request.
|
|
|
|
Requests to create a public (public as in published to the room directory) room which violates
|
|
the configured rules will result in the room being created but not published to the room directory.
|
|
|
|
Each rule is a YAML object containing four fields, each of which is an optional string:
|
|
|
|
* `user_id`: a glob pattern that matches against the user publishing the room.
|
|
* `alias`: a glob pattern that matches against one of published room's aliases.
|
|
- If the room has no aliases, the alias match fails unless `alias` is unspecified or `*`.
|
|
- If the room has exactly one alias, the alias match succeeds if the `alias` pattern matches that alias.
|
|
- If the room has two or more aliases, the alias match succeeds if the pattern matches at least one of the aliases.
|
|
* `room_id`: a glob pattern that matches against the room ID of the room being published.
|
|
* `action`: either `allow` or `deny`. What to do with the request if the rule matches. Defaults to `allow`.
|
|
|
|
Each of the glob patterns is optional, defaulting to `*` ("match anything").
|
|
Note that the patterns match against fully qualified IDs, e.g. against
|
|
`@alice:example.com`, `#room:example.com` and `!abcdefghijk:example.com` instead
|
|
of `alice`, `room` and `abcedgghijk`.
|
|
|
|
|
|
Example configuration:
|
|
|
|
```yaml
|
|
# No rule list specified. Anyone may publish any room to the public list.
|
|
# This is the default behaviour.
|
|
room_list_publication_rules:
|
|
```
|
|
|
|
```yaml
|
|
# A list of one rule which allows everything.
|
|
# This has the same effect as the previous example.
|
|
room_list_publication_rules:
|
|
- "action": "allow"
|
|
```
|
|
|
|
```yaml
|
|
# An empty list of rules. No-one may publish to the room list.
|
|
room_list_publication_rules: []
|
|
```
|
|
|
|
```yaml
|
|
# A list of one rule which denies everything.
|
|
# This has the same effect as the previous example.
|
|
room_list_publication_rules:
|
|
- "action": "deny"
|
|
```
|
|
|
|
```yaml
|
|
# Prevent a specific user from publishing rooms.
|
|
# Allow other users to publish anything.
|
|
room_list_publication_rules:
|
|
- user_id: "@bad_user:example.com"
|
|
action: deny
|
|
|
|
- action: allow
|
|
```
|
|
|
|
```yaml
|
|
# Prevent publication of a specific room.
|
|
room_list_publication_rules:
|
|
- room_id: "!forbiddenRoom:example.com"
|
|
action: deny
|
|
|
|
- action: allow
|
|
```
|
|
|
|
```yaml
|
|
# Prevent publication of rooms with at least one alias containing the word "potato".
|
|
room_list_publication_rules:
|
|
- alias: "#*potato*:example.com"
|
|
action: deny
|
|
|
|
- action: allow
|
|
```
|

|
### `default_power_level_content_override`
|
|
|
|
The `default_power_level_content_override` option controls the default power
|
|
levels for rooms.
|
|
|
|
Useful if you know that your users need special permissions in rooms
|
|
that they create (e.g. to send particular types of state events without
|
|
needing an elevated power level). This takes the same shape as the
|
|
`power_level_content_override` parameter in the /createRoom API, but
|
|
is applied before that parameter.
|
|
|
|
Note that each key provided inside a preset (for example `events` in the example
|
|
below) will overwrite all existing defaults inside that key. So in the example
|
|
below, newly-created private_chat rooms will have no rules for any event types
|
|
except `com.example.foo`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
default_power_level_content_override:
|
|
private_chat: { "events": { "com.example.foo" : 0 } }
|
|
trusted_private_chat: null
|
|
public_chat: null
|
|
```
|
|
|
|
The default power levels for each preset are:
|
|
```yaml
|
|
"m.room.name": 50
|
|
"m.room.power_levels": 100
|
|
"m.room.history_visibility": 100
|
|
"m.room.canonical_alias": 50
|
|
"m.room.avatar": 50
|
|
"m.room.tombstone": 100
|
|
"m.room.server_acl": 100
|
|
"m.room.encryption": 100
|
|
```
|
|
|
|
So a complete example where the default power-levels for a preset are maintained
|
|
but the power level for a new key is set is:
|
|
```yaml
|
|
default_power_level_content_override:
|
|
private_chat:
|
|
events:
|
|
"com.example.foo": 0
|
|
"m.room.name": 50
|
|
"m.room.power_levels": 100
|
|
"m.room.history_visibility": 100
|
|
"m.room.canonical_alias": 50
|
|
"m.room.avatar": 50
|
|
"m.room.tombstone": 100
|
|
"m.room.server_acl": 100
|
|
"m.room.encryption": 100
|
|
trusted_private_chat: null
|
|
public_chat: null
|
|
```
|
|
|
|

|
|
### `forget_rooms_on_leave`
|
|
|
|
Set to true to automatically forget rooms for users when they leave them, either
|
|
normally or via a kick or ban. Defaults to false.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
forget_rooms_on_leave: false
|
|
```
|
|
---
|
|
### `exclude_rooms_from_sync`
|
|
A list of rooms to exclude from sync responses. This is useful for server
|
|
administrators wishing to group users into a room without these users being able
|
|
to see it from their client.
|
|
|
|
By default, no room is excluded.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
exclude_rooms_from_sync:
|
|
- "!foo:example.com"
|
|
```
|
|
|
|
---
|
|
## Opentracing
|
|
Configuration options related to Opentracing support.
|
|
|
|
---
|
|
### `opentracing`
|
|
|
|
These settings enable and configure opentracing, which implements distributed tracing.
|
|
This allows you to observe the causal chains of events across servers
|
|
including requests, key lookups etc., across any server running
|
|
synapse or any other services which support opentracing
|
|
(specifically those implemented with Jaeger).
|
|
|
|
Sub-options include:
|
|
* `enabled`: whether tracing is enabled. Set to true to enable. Disabled by default.
|
|
* `homeserver_whitelist`: The list of homeservers we wish to send and receive span contexts and span baggage.
|
|
See [here](../../opentracing.md) for more.
|
|
This is a list of regexes which are matched against the `server_name` of the homeserver.
|
|
By default, it is empty, so no servers are matched.
|
|
* `force_tracing_for_users`: # A list of the matrix IDs of users whose requests will always be traced,
|
|
even if the tracing system would otherwise drop the traces due to probabilistic sampling.
|
|
By default, the list is empty.
|
|
* `jaeger_config`: Jaeger can be configured to sample traces at different rates.
|
|
All configuration options provided by Jaeger can be set here. Jaeger's configuration is
|
|
mostly related to trace sampling which is documented [here](https://www.jaegertracing.io/docs/latest/sampling/).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
opentracing:
|
|
enabled: true
|
|
homeserver_whitelist:
|
|
- ".*"
|
|
force_tracing_for_users:
|
|
- "@user1:server_name"
|
|
- "@user2:server_name"
|
|
|
|
jaeger_config:
|
|
sampler:
|
|
type: const
|
|
param: 1
|
|
logging:
|
|
false
|
|
```
|
|
---
|
|
## Coordinating workers
|
|
Configuration options related to workers which belong in the main config file
|
|
(usually called `homeserver.yaml`).
|
|
A Synapse deployment can scale horizontally by running multiple Synapse processes
|
|
called _workers_. Incoming requests are distributed between workers to handle higher
|
|
loads. Some workers are privileged and can accept requests from other workers.
|
|
|
|
As a result, the worker configuration is divided into two parts.
|
|
|
|
1. The first part (in this section of the manual) defines which shardable tasks
|
|
are delegated to privileged workers. This allows unprivileged workers to make
|
|
requests to a privileged worker to act on their behalf.
|
|
1. [The second part](#individual-worker-configuration)
|
|
controls the behaviour of individual workers in isolation.
|
|
|
|
For guidance on setting up workers, see the [worker documentation](../../workers.md).
|
|
|
|
---
|
|
### `worker_replication_secret`
|
|
|
|
A shared secret used by the replication APIs on the main process to authenticate
|
|
HTTP requests from workers.
|
|
|
|
The default, this value is omitted (equivalently `null`), which means that
|
|
traffic between the workers and the main process is not authenticated.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_replication_secret: "secret_secret"
|
|
```
|
|
---
|
|
### `start_pushers`
|
|
|
|
Unnecessary to set if using [`pusher_instances`](#pusher_instances) with [`generic_workers`](../../workers.md#synapseappgeneric_worker).
|
|
|
|
Controls sending of push notifications on the main process. Set to `false`
|
|
if using a [pusher worker](../../workers.md#synapseapppusher). Defaults to `true`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
start_pushers: false
|
|
```
|
|
---
|
|
### `pusher_instances`
|
|
|
|
It is possible to scale the processes that handle sending push notifications to [sygnal](https://github.com/matrix-org/sygnal)
|
|
and email by running a [`generic_worker`](../../workers.md#synapseappgeneric_worker) and adding it's [`worker_name`](#worker_name) to
|
|
a `pusher_instances` map. Doing so will remove handling of this function from the main
|
|
process. Multiple workers can be added to this map, in which case the work is balanced
|
|
across them. Ensure the main process and all pusher workers are restarted after changing
|
|
this option.
|
|
|
|
Example configuration for a single worker:
|
|
```yaml
|
|
pusher_instances:
|
|
- pusher_worker1
|
|
```
|
|
And for multiple workers:
|
|
```yaml
|
|
pusher_instances:
|
|
- pusher_worker1
|
|
- pusher_worker2
|
|
```
|
|
|
|
---
|
|
### `send_federation`
|
|
|
|
Unnecessary to set if using [`federation_sender_instances`](#federation_sender_instances) with [`generic_workers`](../../workers.md#synapseappgeneric_worker).
|
|
|
|
Controls sending of outbound federation transactions on the main process.
|
|
Set to `false` if using a [federation sender worker](../../workers.md#synapseappfederation_sender).
|
|
Defaults to `true`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
send_federation: false
|
|
```
|
|
---
|
|
### `federation_sender_instances`
|
|
|
|
It is possible to scale the processes that handle sending outbound federation requests
|
|
by running a [`generic_worker`](../../workers.md#synapseappgeneric_worker) and adding it's [`worker_name`](#worker_name) to
|
|
a `federation_sender_instances` map. Doing so will remove handling of this function from
|
|
the main process. Multiple workers can be added to this map, in which case the work is
|
|
balanced across them.
|
|
|
|
This configuration setting must be shared between all workers handling federation
|
|
sending, and if changed all federation sender workers must be stopped at the same time
|
|
and then started, to ensure that all instances are running with the same config (otherwise
|
|
events may be dropped).
|
|
|
|
Example configuration for a single worker:
|
|
```yaml
|
|
federation_sender_instances:
|
|
- federation_sender1
|
|
```
|
|
And for multiple workers:
|
|
```yaml
|
|
federation_sender_instances:
|
|
- federation_sender1
|
|
- federation_sender2
|
|
```
|
|
---
|
|
### `instance_map`
|
|
|
|
When using workers this should be a map from [`worker_name`](#worker_name) to the HTTP
|
|
replication listener of the worker, if configured, and to the main process. Each worker
|
|
declared under [`stream_writers`](../../workers.md#stream-writers) and
|
|
[`outbound_federation_restricted_to`](#outbound_federation_restricted_to) needs a HTTP
|
|
replication listener, and that listener should be included in the `instance_map`. The
|
|
main process also needs an entry on the `instance_map`, and it should be listed under
|
|
`main` **if even one other worker exists**. Ensure the port matches with what is
|
|
declared inside the `listener` block for a `replication` listener.
|
|
|
|
|
|
Example configuration:
|
|
```yaml
|
|
instance_map:
|
|
main:
|
|
host: localhost
|
|
port: 8030
|
|
worker1:
|
|
host: localhost
|
|
port: 8034
|
|
```
|
|
Example configuration(#2, for UNIX sockets):
|
|
```yaml
|
|
instance_map:
|
|
main:
|
|
path: /run/synapse/main_replication.sock
|
|
worker1:
|
|
path: /run/synapse/worker1_replication.sock
|
|
```
|
|
---
|
|
### `stream_writers`
|
|
|
|
Experimental: When using workers you can define which workers should
|
|
handle writing to streams such as event persistence and typing notifications.
|
|
Any worker specified here must also be in the [`instance_map`](#instance_map).
|
|
|
|
See the list of available streams in the
|
|
[worker documentation](../../workers.md#stream-writers).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
stream_writers:
|
|
events: worker1
|
|
typing: worker1
|
|
```
|
|
---
|
|
### `outbound_federation_restricted_to`
|
|
|
|
When using workers, you can restrict outbound federation traffic to only go through a
|
|
specific subset of workers. Any worker specified here must also be in the
|
|
[`instance_map`](#instance_map).
|
|
[`worker_replication_secret`](#worker_replication_secret) must also be configured to
|
|
authorize inter-worker communication.
|
|
|
|
```yaml
|
|
outbound_federation_restricted_to:
|
|
- federation_sender1
|
|
- federation_sender2
|
|
```
|
|
|
|
Also see the [worker
|
|
documentation](../../workers.md#restrict-outbound-federation-traffic-to-a-specific-set-of-workers)
|
|
for more info.
|
|
|
|
_Added in Synapse 1.89.0._
|
|
|
|
---
|
|
### `run_background_tasks_on`
|
|
|
|
The [worker](../../workers.md#background-tasks) that is used to run
|
|
background tasks (e.g. cleaning up expired data). If not provided this
|
|
defaults to the main process.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
run_background_tasks_on: worker1
|
|
```
|
|
---
|
|
### `update_user_directory_from_worker`
|
|
|
|
The [worker](../../workers.md#updating-the-user-directory) that is used to
|
|
update the user directory. If not provided this defaults to the main process.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
update_user_directory_from_worker: worker1
|
|
```
|
|
|
|
_Added in Synapse 1.59.0._
|
|
|
|
---
|
|
### `notify_appservices_from_worker`
|
|
|
|
The [worker](../../workers.md#notifying-application-services) that is used to
|
|
send output traffic to Application Services. If not provided this defaults
|
|
to the main process.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
notify_appservices_from_worker: worker1
|
|
```
|
|
|
|
_Added in Synapse 1.59.0._
|
|
|
|
---
|
|
### `media_instance_running_background_jobs`
|
|
|
|
The [worker](../../workers.md#synapseappmedia_repository) that is used to run
|
|
background tasks for media repository. If running multiple media repositories
|
|
you must configure a single instance to run the background tasks. If not provided
|
|
this defaults to the main process or your single `media_repository` worker.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
media_instance_running_background_jobs: worker1
|
|
```
|
|
|
|
_Added in Synapse 1.16.0._
|
|
|
|
---
|
|
### `redis`
|
|
|
|
Configuration for Redis when using workers. This *must* be enabled when using workers.
|
|
This setting has the following sub-options:
|
|
* `enabled`: whether to use Redis support. Defaults to false.
|
|
* `host` and `port`: Optional host and port to use to connect to redis. Defaults to
|
|
localhost and 6379
|
|
* `path`: The full path to a local Unix socket file. **If this is used, `host` and
|
|
`port` are ignored.** Defaults to `/tmp/redis.sock'
|
|
* `password`: Optional password if configured on the Redis instance.
|
|
* `dbid`: Optional redis dbid if needs to connect to specific redis logical db.
|
|
* `use_tls`: Whether to use tls connection. Defaults to false.
|
|
* `certificate_file`: Optional path to the certificate file
|
|
* `private_key_file`: Optional path to the private key file
|
|
* `ca_file`: Optional path to the CA certificate file. Use this one or:
|
|
* `ca_path`: Optional path to the folder containing the CA certificate file
|
|
|
|
_Added in Synapse 1.78.0._
|
|
|
|
_Changed in Synapse 1.84.0: Added use\_tls, certificate\_file, private\_key\_file, ca\_file and ca\_path attributes_
|
|
|
|
_Changed in Synapse 1.85.0: Added path option to use a local Unix socket_
|
|
|
|
Example configuration:
|
|
```yaml

|
#ca_file: <path_to_the_ca_certificate_file>
|
|
```

|
|
## Individual worker configuration
|
|
These options configure an individual worker, in its worker configuration file.
|
|
They should be not be provided when configuring the main process.
|
|
|
|
Note also the configuration above for
|
|
[coordinating a cluster of workers](#coordinating-workers).
|
|
|
|
For guidance on setting up workers, see the [worker documentation](../../workers.md).
|
|
|
|
---
|
|
### `worker_app`
|
|
|
|
The type of worker. The currently available worker applications are listed
|
|
in [worker documentation](../../workers.md#available-worker-applications).
|
|
|
|
The most common worker is the
|
|
[`synapse.app.generic_worker`](../../workers.md#synapseappgeneric_worker).
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_app: synapse.app.generic_worker
|
|
```
|
|
---
|
|
### `worker_name`
|
|
|
|
A unique name for the worker. The worker needs a name to be addressed in
|
|
further parameters and identification in log files. We strongly recommend
|
|
giving each worker a unique `worker_name`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_name: generic_worker1
|
|
```
|
|
---
|
|
### `worker_listeners`
|
|
|
|
A worker can handle HTTP requests. To do so, a `worker_listeners` option
|
|
must be declared, in the same way as the [`listeners` option](#listeners)
|
|
in the shared config.
|
|
|
|
Workers declared in [`stream_writers`](#stream_writers) and [`instance_map`](#instance_map)
|
|
will need to include a `replication` listener here, in order to accept internal HTTP
|
|
requests from other workers.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_listeners:
|
|
- type: http
|
|
port: 8083
|
|
resources:
|
|
- names: [client, federation]
|
|
```
|
|
Example configuration(#2, using UNIX sockets with a `replication` listener):
|
|
```yaml
|
|
worker_listeners:
|
|
- type: http
|
|
path: /run/synapse/worker_replication.sock
|
|
resources:
|
|
- names: [replication]
|
|
- type: http
|
|
path: /run/synapse/worker_public.sock
|
|
resources:
|
|
- names: [client, federation]
|
|
```
|
|
---
|
|
### `worker_manhole`
|
|
|
|
A worker may have a listener for [`manhole`](../../manhole.md).
|
|
It allows server administrators to access a Python shell on the worker.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_manhole: 9000
|
|
```
|
|
|
|
This is a short form for:
|
|
```yaml
|
|
worker_listeners:
|
|
- port: 9000
|
|
bind_addresses: ['127.0.0.1']
|
|
type: manhole
|
|
```
|
|
|
|
It needs also an additional [`manhole_settings`](#manhole_settings) configuration.

### `worker_daemonize`
|
|
|
|
Specifies whether the worker should be started as a daemon process.
|
|
If Synapse is being managed by [systemd](../../systemd-with-workers/), this option
|
|
must be omitted or set to `false`.
|
|
|
|
Defaults to `false`.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_daemonize: true
|
|
```
|
|
---
|
|
### `worker_pid_file`
|
|
|
|
When running a worker as a daemon, we need a place to store the
|
|
[PID](https://en.wikipedia.org/wiki/Process_identifier) of the worker.
|
|
This option defines the location of that "pid file".
|
|
|
|
This option is required if `worker_daemonize` is `true` and ignored
|
|
otherwise. It has no default.
|
|
|
|
See also the [`pid_file` option](#pid_file) option for the main Synapse process.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_pid_file: DATADIR/generic_worker1.pid
|
|
```
|

|
|
### `worker_log_config`
|
|
|
|
This option specifies a yaml python logging config file as described
|
|
[here](https://docs.python.org/3/library/logging.config.html#configuration-dictionary-schema).
|
|
See also the [`log_config` option](#log_config) option for the main Synapse process.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
worker_log_config: /etc/matrix-synapse/generic-worker-log.yaml
|
|
```

## Background Updates
|
|
Configuration settings related to background updates.
|
|
|
|
---
|
|
### `background_updates`
|
|
|
|
Background updates are database updates that are run in the background in batches.
|
|
The duration, minimum batch size, default batch size, whether to sleep between batches and if so, how long to
|
|
sleep can all be configured. This is helpful to speed up or slow down the updates.
|
|
This setting has the following sub-options:
|
|
* `background_update_duration_ms`: How long in milliseconds to run a batch of background updates for. Defaults to 100.
|
|
Set a different time to change the default.
|
|
* `sleep_enabled`: Whether to sleep between updates. Defaults to true. Set to false to change the default.
|
|
* `sleep_duration_ms`: If sleeping between updates, how long in milliseconds to sleep for. Defaults to 1000.
|
|
Set a duration to change the default.
|
|
* `min_batch_size`: Minimum size a batch of background updates can be. Must be greater than 0. Defaults to 1.
|
|
Set a size to change the default.
|
|
* `default_batch_size`: The batch size to use for the first iteration of a new background update. The default is 100.
|
|
Set a size to change the default.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
background_updates:
|
|
background_update_duration_ms: 500
|
|
sleep_enabled: false
|
|
sleep_duration_ms: 300
|
|
min_batch_size: 10
|
|
default_batch_size: 50
|
|
```

|
## Auto Accept Invites
|
|
Configuration settings related to automatically accepting invites.
|
|
|
|
---
|
|
### `auto_accept_invites`
|
|
|
|
Automatically accepting invites controls whether users are presented with an invite request or if they
|
|
are instead automatically joined to a room when receiving an invite. Set the `enabled` sub-option to true to
|
|
enable auto-accepting invites. Defaults to false.
|
|
This setting has the following sub-options:
|
|
* `enabled`: Whether to run the auto-accept invites logic. Defaults to false.
|
|
* `only_for_direct_messages`: Whether invites should be automatically accepted for all room types, or only
|
|
for direct messages. Defaults to false.
|
|
* `only_from_local_users`: Whether to only automatically accept invites from users on this homeserver. Defaults to false.
|
|
* `worker_to_run_on`: Which worker to run this module on. This must match the "worker_name".
|
|
|
|
NOTE: Care should be taken not to enable this setting if the `synapse_auto_accept_invite` module is enabled and installed.
|
|
The two modules will compete to perform the same task and may result in undesired behaviour. For example, multiple join
|
|
events could be generated from a single invite.
|
|
|
|
Example configuration:
|
|
```yaml
|
|
auto_accept_invites:
|
|
enabled: true
|
|
only_for_direct_messages: true
|
|
only_from_local_users: true
|
|
worker_to_run_on: "worker_1"
|
|
```
