Port 8008 is +configured without TLS; it should be behind a reverse proxy for TLS/SSL +termination on port 443 which in turn should be used for clients. Port 8448 +is configured to use TLS for Federation with a self-signed or verified +certificate, but please be aware that a valid certificate will be required in +Synapse v1.0. + +If you would like to use your own certificates, you can do so by changing +`tls_certificate_path` and `tls_private_key_path` in `homeserver.yaml`; +alternatively, you can use a reverse-proxy. Apart from port 8448 using TLS, +both ports are the same in the default configuration. + +### ACME setup + +Synapse v1.0 will require valid TLS certificates for communication between servers +(port `8448` by default) in addition to those that are client-facing (port +`443`). In the case that your `server_name` config variable is the same as +the hostname that the client connects to, then the same certificate can be +used between client and federation ports without issue. Synapse v0.99.0+ +**will provision server-to-server certificates automatically for you for +free** through [Let's Encrypt](https://letsencrypt.org/) if you tell it to. + +In order for Synapse to complete the ACME challenge to provision a +certificate, it needs access to port 80. Typically listening on port 80 is +only granted to applications running as root. There are thus two solutions to +this problem. + +#### Using a reverse proxy + +A reverse proxy such as Apache or nginx allows a single process (the web +server) to listen on port 80 and proxy traffic to the appropriate program +running on your server. It is the recommended method for setting up ACME as +it allows you to use your existing webserver while also allowing Synapse to +provision certificates as needed. + +For nginx users, add the following line to your existing `server` block: + +``` +location /.well-known/acme-challenge { + proxy_pass http://localhost:8009/; +} +``` + +For Apache, add the following to your existing webserver config:: + +``` +ProxyPass /.well-known/acme-challenge http://localhost:8009/.well-known/acme-challenge +``` + +Make sure to restart/reload your webserver after making changes. + + +#### Authbind + +`authbind` allows a program which does not run as root to bind to +low-numbered ports in a controlled way. The setup is simpler, but requires a +webserver not to already be running on port 80. **This includes every time +Synapse renews a certificate**, which may be cumbersome if you usually run a +web server on port 80. Nevertheless, if you're sure port 80 is not being used +for any other purpose then all that is necessary is the following: + +Install `authbind`. For example, on Debian/Ubuntu: + +``` +sudo apt-get install authbind +``` + +Allow `authbind` to bind port 80: + +``` +sudo touch /etc/authbind/byport/80 +sudo chmod 777 /etc/authbind/byport/80 +``` + +When Synapse is started, use the following syntax:: + +``` +authbind --deep +``` + +Finally, once Synapse is able to listen on port 80 for ACME challenge +requests, it must be told to perform ACME provisioning by setting `enabled` +to true under the `acme` section in `homeserver.yaml`: + +``` +acme: + enabled: true +``` + +## Registering a user + +You will need at least one user on your server in order to use a Matrix +client. Users can be registered either via a Matrix client, or via a +commandline script. + +To get started, it is easiest to use the command line to register new +users. This can be done as follows: + +``` +$ source ~/synapse/env/bin/activate +$ synctl start # if not already running +$ register_new_matrix_user -c homeserver.yaml https://localhost:8448 +New user localpart: erikj +Password: +Confirm password: +Make admin [no]: +Success! +``` + +This process uses a setting ``registration_shared_secret`` in +``homeserver.yaml``, which is shared between Synapse itself and the +``register_new_matrix_user`` script. It doesn't matter what it is (a random +value is generated by ``--generate-config``), but it should be kept secret, as +anyone with knowledge of it can register users on your server even if +``enable_registration`` is ``false``. + +## Setting up a TURN server + +For reliable VoIP calls to be routed via this homeserver, you MUST configure +a TURN server. See [docs/turn-howto.rst](docs/turn-howto.rst) for details. + +## URL previews + +Synapse includes support for previewing URLs, which is disabled by default. To +turn it on you must enable the ``url_preview_enabled: True`` config parameter +and explicitly specify the IP ranges that Synapse is not allowed to spider for +previewing in the ``url_preview_ip_range_blacklist`` configuration parameter. +This is critical from a security perspective to stop arbitrary Matrix users +spidering 'internal' URLs on your network. At the very least we recommend that +your loopback and RFC1918 IP addresses are blacklisted. + +This also requires the optional lxml and netaddr python dependencies to be +installed. This in turn requires the libxml2 library to be available - on +Debian/Ubuntu this means ``apt-get install libxml2-dev``, or equivalent for +your OS. diff --git a/README.rst b/README.rst index 9e3d85de4c..8c5220be88 100644 --- a/README.rst +++ b/README.rst @@ -81,261 +81,8 @@ Thanks for using Matrix!
