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 alter the +<code>server_name</code> 's https server to serve the <code>/.well-known/matrix/server</code> +URL. Having an active server (with a valid TLS certificate) serving your +<code>server_name</code> domain is out of the scope of this documentation.</p> +<p>The URL <code>https://<server_name>/.well-known/matrix/server</code> should +return a JSON structure containing the key <code>m.server</code> like so:</p> +<pre><code class="language-json">{ + "m.server": "<synapse.server.name>[:<yourport>]" +} +</code></pre> +<p>In our example, this would mean that URL <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> +<p>With .well-known delegation, federating servers will check for a valid TLS +certificate for the delegated hostname (in our example: <code>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 +considered an advanced topic since it's a bit complex to set up, and <code>.well-known</code> +delegation is already enough in most cases.</p> +<p>However, if you really need it, you can find some documentation on how 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="do-you-still-recommend-against-using-a-reverse-proxy-on-the-federation-port"><a class="header" href="#do-you-still-recommend-against-using-a-reverse-proxy-on-the-federation-port">Do you still recommend against using a reverse proxy on the federation port?</a></h3> +<p>We no longer actively recommend against using a reverse proxy.

If you are using a reverse proxy for all of your +TLS traffic, then you can set <code>no_tls: True</code> in the Synapse config.</p> +<p>In that case, the only reason Synapse needs the certificate is to populate a legacy +<code>tls_fingerprints</code> field in the federation API. This is ignored by Synapse 0.99.0 +and later, and the only time pre-0.99 Synapses will check it is when attempting to +fetch the server keys - and generally this is delegated via <code>matrix.org</code>, which +is running a modern version of Synapse.</p> +<h3 id="do-i-need-the-same-certificate-for-the-client-and-federation-port"><a class="header" href="#do-i-need-the-same-certificate-for-the-client-and-federation-port">Do I need the same certificate for the client and federation port?</a></h3> +<p>No. There is nothing stopping you from using different certificates, +particularly if you are using a reverse proxy.</p> + + </main> + + <nav class="nav-wrapper" aria-label="Page navigation"> + <!-- Mobile navigation buttons --> + + <a rel="prev" href="turn-howto.html" class="mobile-nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + + + + <a rel="next" href="upgrade.html" class="mobile-nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + + + <div style="clear: both"></div> + </nav> + </div> + </div> + + <nav class="nav-wide-wrapper" aria-label="Page navigation"> + + <a rel="prev" href="turn-howto.html" class="nav-chapters previous" title="Previous chapter" aria-label="Previous chapter" aria-keyshortcuts="Left"> + <i class="fa fa-angle-left"></i> + </a> + + + + <a rel="next" href="upgrade.html" class="nav-chapters next" title="Next chapter" aria-label="Next chapter" aria-keyshortcuts="Right"> + <i class="fa fa-angle-right"></i> + </a> + + </nav> + + </div> + + + + + + + + + <script type="text/javascript"> + window.playground_copyable = true; + </script> + + + + + + <script src="elasticlunr.min.js" type="text/javascript" charset="utf-8"></script> + <script src="mark.min.js" type="text/javascript" charset="utf-8"></script> + <script src="searcher.js" type="text/javascript" charset="utf-8"></script> + + + <script src="clipboard.min.js" type="text/javascript" charset="utf-8"></script> + <script src="highlight.js" type="text/javascript" charset="utf-8"></script> + <script src="book.js" type="text/javascript" charset="utf-8"></script> + + <!-- Custom JS scripts --> + + <script type="text/javascript" src="docs/website_files/table-of-contents.js"></script> + + + + + </body> +</html> \ No newline at end of file |
