It appears at the ends of user ids, and tells +other homeservers where they can find your server.</p> +<p>By default, other homeservers will expect to be able to reach yours via +your <code>server_name</code>, on port 8448. For example, if you set your <code>server_name</code> +to <code>example.com</code> (so that your user names look like <code>@user:example.com</code>), +other servers will try to connect to yours at <code>https://example.com:8448/</code>.</p> +<p>Delegation is a Matrix feature allowing a homeserver admin to retain a +<code>server_name</code> of <code>example.com</code> so that user IDs, room aliases, etc continue +to look like <code>*:example.com</code>, whilst having federation traffic routed +to a different server and/or port (e.g. <code>synapse.example.com:443</code>).</p> +<h2 id="well-known-delegation"><a class="header" href="#well-known-delegation">.well-known delegation</a></h2> +<p>To use this method, you need to be able to configure the server at +<code>https://<server_name></code> to serve a file at +<code>https://<server_name>/.well-known/matrix/server</code>. There are two ways to do this, shown below.</p> +<p>Note that the <code>.well-known</code> file is hosted on the default port for <code>https</code> (port 443).</p> +<h3 id="external-server"><a class="header" href="#external-server">External server</a></h3> +<p>For maximum flexibility, you need to configure an external server such as nginx, Apache +or HAProxy to serve the <code>https://<server_name>/.well-known/matrix/server</code> file. Setting +up such a server is out of the scope of this documentation, but note that it is often +possible to configure your <a href="reverse_proxy.html">reverse proxy</a> for this.</p> +<p>The URL <code>https://<server_name>/.well-known/matrix/server</code> should be configured +return a JSON structure containing the key <code>m.server</code> like this:</p> +<pre><code class="language-json">{ + "m.server": "<synapse.server.name>[:<yourport>]" +} +</code></pre> +<p>In our example (where we want federation traffic to be routed to +<code>https://synapse.example.com</code>, on port 443), this would mean that +<code>https://example.com/.well-known/matrix/server</code> should return:</p> +<pre><code class="language-json">{ + "m.server": "synapse.example.com:443" +} +</code></pre> +<p>Note, specifying a port is optional. If no port is specified, then it defaults +to 8448.</p> +<h3 id="serving-a-well-knownmatrixserver-file-with-synapse"><a class="header" href="#serving-a-well-knownmatrixserver-file-with-synapse">Serving a <code>.well-known/matrix/server</code> file with Synapse</a></h3> +<p>If you are able to set up your domain so that <code>https://<server_name></code> is routed to +Synapse (i.e., the only change needed is to direct federation traffic to port 443 +instead of port 8448), then it is possible to configure Synapse to serve a suitable +<code>.well-known/matrix/server</code> file. To do so, add the following to your <code>homeserver.yaml</code> +file:</p> +<pre><code class="language-yaml">serve_server_wellknown: true +</code></pre> +<p><strong>Note</strong>: this <em>only</em> works if <code>https://<server_name></code> is routed to Synapse, so is +generally not suitable if Synapse is hosted at a subdomain such as +<code>https://synapse.example.com</code>.</p> +<h2 id="srv-dns-record-delegation"><a class="header" href="#srv-dns-record-delegation">SRV DNS record delegation</a></h2> +<p>It is also possible to do delegation using a SRV DNS record. However, that is generally +not recommended, as it can be difficult to configure the TLS certificates correctly in +this case, and it offers little advantage over <code>.well-known</code> delegation.</p> +<p>Please keep in mind that server delegation is a function of server-server communication, +and as such using SRV DNS records will not cover use cases involving client-server comms. +This means setting global client settings (such as a Jitsi endpoint, or disabling +creating new rooms as encrypted by default, etc) will still require that you serve a file +from the <code>https://<server_name>/.well-known/</code> endpoints defined in the spec! If you are +considering using SRV DNS delegation to avoid serving files from this endpoint, consider +the impact that you will not be able to change those client-based default values globally, +and will be relegated to the featureset of the configuration of each individual client.</p> +<p>However, if you really need it, you can find some documentation on what such a +record should look like and how Synapse will use it in <a href="https://matrix.org/docs/spec/server_server/latest#resolving-server-names">the Matrix +specification</a>.</p> +<h2 id="delegation-faq"><a class="header" href="#delegation-faq">Delegation FAQ</a></h2> +<h3 id="when-do-i-need-delegation"><a class="header" href="#when-do-i-need-delegation">When do I need delegation?</a></h3> +<p>If your homeserver's APIs are accessible on the default federation port (8448) +and the domain your <code>server_name</code> points to, you do not need any delegation.</p> +<p>For instance, if you registered <code>example.com</code> and pointed its DNS A record at a +fresh server, you could install Synapse on that host, giving it a <code>server_name</code> +of <code>example.com</code>, and once a reverse proxy has been set up to proxy all requests +sent to the port <code>8448</code> and serve TLS certificates for <code>example.com</code>, you +wouldn't need any delegation set up.</p> +<p><strong>However</strong>, if your homeserver's APIs aren't accessible on port 8448 and on the +domain <code>server_name</code> points to, you will need to let other servers know how to +find it using delegation.</p> +<h3 id="should-i-use-a-reverse-proxy-for-federation-traffic"><a class="header" href="#should-i-use-a-reverse-proxy-for-federation-traffic">Should I use a reverse proxy for federation traffic?</a></h3> +<p>Generally, using a reverse proxy for both the federation and client traffic is a good +idea, since it saves handling TLS traffic in Synapse.
