Unpack it and <code>cd</code> into the directory.</p> +</li> +<li> +<p>Configure it:</p> +<pre><code>./configure +</code></pre> +<p>You may need to install <code>libevent2</code>: if so, you should do so in +the way recommended by your operating system. You can ignore +warnings about lack of database support: a database is unnecessary +for this purpose.</p> +</li> +<li> +<p>Build and install it:</p> +<pre><code>make +make install +</code></pre> +</li> +</ol> +<h3 id="configuration"><a class="header" href="#configuration">Configuration</a></h3> +<ol> +<li> +<p>Create or edit the config file in <code>/etc/turnserver.conf</code>. The relevant +lines, with example values, are:</p> +<pre><code>use-auth-secret +static-auth-secret=[your secret key here] +realm=turn.myserver.org +</code></pre> +<p>See <code>turnserver.conf</code> for explanations of the options. One way to generate +the <code>static-auth-secret</code> is with <code>pwgen</code>:</p> +<pre><code>pwgen -s 64 1 +</code></pre> +<p>A <code>realm</code> must be specified, but its value is somewhat arbitrary. (It is +sent to clients as part of the authentication flow.) It is conventional to +set it to be your server name.</p> +</li> +<li> +<p>You will most likely want to configure coturn to write logs somewhere. The +easiest way is normally to send them to the syslog:</p> +<pre><code>syslog +</code></pre> +<p>(in which case, the logs will be available via <code>journalctl -u coturn</code> on a +systemd system). Alternatively, coturn can be configured to write to a +logfile - check the example config file supplied with coturn.</p> +</li> +<li> +<p>Consider your security settings. TURN lets users request a relay which will +connect to arbitrary IP addresses and ports. The following configuration is +suggested as a minimum starting point:</p> +<pre><code># VoIP traffic is all UDP. There is no reason to let users connect to arbitrary TCP endpoints via the relay. +no-tcp-relay + +# don't let the relay ever try to connect to private IP address ranges within your network (if any) +# given the turn server is likely behind your firewall, remember to include any privileged public IPs too. +denied-peer-ip=10.0.0.0-10.255.255.255 +denied-peer-ip=192.168.0.0-192.168.255.255 +denied-peer-ip=172.16.0.0-172.31.255.255 + +# special case the turn server itself so that client->TURN->TURN->client flows work +allowed-peer-ip=10.0.0.1 + +# consider whether you want to limit the quota of relayed streams per user (or total) to avoid risk of DoS. +user-quota=12 # 4 streams per video call, so 12 streams = 3 simultaneous relayed calls per user. +total-quota=1200 +</code></pre> +</li> +<li> +<p>Also consider supporting TLS/DTLS. To do this, add the following settings +to <code>turnserver.conf</code>:</p> +<pre><code># TLS certificates, including intermediate certs. +# For Let's Encrypt certificates, use `fullchain.pem` here. +cert=/path/to/fullchain.pem + +# TLS private key file +pkey=/path/to/privkey.pem +</code></pre> +<p>In this case, replace the <code>turn:</code> schemes in the <code>turn_uri</code> settings below +with <code>turns:</code>.</p> +<p>We recommend that you only try to set up TLS/DTLS once you have set up a +basic installation and got it working.</p> +</li> +<li> +<p>Ensure your firewall allows traffic into the TURN server on the ports +you've configured it to listen on (By default: 3478 and 5349 for TURN +traffic (remember to allow both TCP and UDP traffic), and ports 49152-65535 +for the UDP relay.)</p> +</li> +<li> +<p>We do not recommend running a TURN server behind NAT, and are not aware of +anyone doing so successfully.</p> +<p>If you want to try it anyway, you will at least need to tell coturn its +external IP address:</p> +<pre><code>external-ip=192.88.99.1 +</code></pre> +<p>... and your NAT gateway must forward all of the relayed ports directly +(eg, port 56789 on the external IP must be always be forwarded to port +56789 on the internal IP).</p> +<p>If you get this working, let us know!</p> +</li> +<li> +<p>(Re)start the turn server:</p> +<ul> +<li> +<p>If you used the Debian package (or have set up a systemd unit yourself):</p> +<pre><code class="language-sh">systemctl restart coturn +</code></pre> +</li> +<li> +<p>If you installed from source:</p> +<pre><code class="language-sh">bin/turnserver -o +</code></pre> +</li> +</ul> +</li> +</ol> +<h2 id="synapse-setup"><a class="header" href="#synapse-setup">Synapse setup</a></h2> +<p>Your home server configuration file needs the following extra keys:</p> +<ol> +<li>"<code>turn_uris</code>": This needs to be a yaml list of public-facing URIs +for your TURN server to be given out to your clients. Add separate +entries for each transport your TURN server supports.</li> +<li>"<code>turn_shared_secret</code>": This is the secret shared between your +Home server and your TURN server, so you should set it to the same +string you used in turnserver.conf.</li> +<li>"<code>turn_user_lifetime</code>": This is the amount of time credentials +generated by your Home Server are valid for (in milliseconds). +Shorter times offer less potential for abuse at the expense of +increased traffic between web clients and your home server to +refresh credentials.

This is enabled by default, as otherwise VoIP will +not work reliably for guests.

The +<code>turn_uris</code> are appropriate for TURN servers listening on the default ports, with no TLS.</p> +<pre><code>turn_uris: [ "turn:turn.matrix.org?transport=udp", "turn:turn.matrix.org?transport=tcp" ] +turn_shared_secret: "n0t4ctuAllymatr1Xd0TorgSshar3d5ecret4obvIousreAsons" +turn_user_lifetime: 86400000 +turn_allow_guests: True +</code></pre> +<p>After updating the homeserver configuration, you must restart synapse:</p> +<ul> +<li>If you use synctl: +<pre><code class="language-sh">cd /where/you/run/synapse +./synctl restart +</code></pre> +</li> +<li>If you use systemd: +<pre><code>systemctl restart matrix-synapse.service +</code></pre> +</li> +</ul> +<p>... and then reload any clients (or wait an hour for them to refresh their +settings).</p> +<h2 id="troubleshooting"><a class="header" href="#troubleshooting">Troubleshooting</a></h2> +<p>The normal symptoms of a misconfigured TURN server are that calls between +devices on different networks ring, but get stuck at "call +connecting". Unfortunately, troubleshooting this can be tricky.</p> +<p>Here are a few things to try:</p> +<ul> +<li> +<p>Check that your TURN server is not behind NAT. As above, we're not aware of +anyone who has successfully set this up.</p> +</li> +<li> +<p>Check that you have opened your firewall to allow TCP and UDP traffic to the +TURN ports (normally 3478 and 5479).</p> +</li> +<li> +<p>Check that you have opened your firewall to allow UDP traffic to the UDP +relay ports (49152-65535 by default).</p> +</li> +<li> +<p>Some WebRTC implementations (notably, that of Google Chrome) appear to get +confused by TURN servers which are reachable over IPv6 (this appears to be +an unexpected side-effect of its handling of multiple IP addresses as +defined by +<a href="https://tools.ietf.org/html/draft-ietf-rtcweb-ip-handling-12"><code>draft-ietf-rtcweb-ip-handling</code></a>).</p> +<p>Try removing any AAAA records for your TURN server, so that it is only +reachable over IPv4.</p> +</li> +<li> +<p>Enable more verbose logging in coturn via the <code>verbose</code> setting:</p> +<pre><code>verbose +</code></pre> +<p>... and then see if there are any clues in its logs.</p> +</li> +<li> +<p>If you are using a browser-based client under Chrome, check +<code>chrome://webrtc-internals/</code> for insights into the internals of the +negotiation. On Firefox, check the "Connection Log" on <code>about:webrtc</code>.</p> +<p>(Understanding the output is beyond the scope of this document!)</p> +</li> +<li> +<p>You can test your Matrix homeserver TURN setup with https://test.voip.librepush.net/. +Note that this test is not fully reliable yet, so don't be discouraged if +the test fails. +<a href="https://github.com/matrix-org/voip-tester">Here</a> is the github repo of the +source of the tester, where you can file bug reports.</p> +</li> +<li> +<p>There is a WebRTC test tool at +https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/. To +use it, you will need a username/password for your TURN server. You can +either:</p> +<ul> +<li> +<p>look for the <code>GET /_matrix/client/r0/voip/turnServer</code> request made by a +matrix client to your homeserver in your browser's network inspector. In +the response you should see <code>username</code> and <code>password</code>. Or:</p> +</li> +<li> +<p>Use the following shell commands:</p> +<pre><code class="language-sh">secret=staticAuthSecretHere + +u=$((`date +%s` + 3600)):test +p=$(echo -n $u | openssl dgst -hmac $secret -sha1 -binary | base64) +echo -e "username: $u\npassword: $p" +</code></pre> +<p>Or:</p> +</li> +<li> +<p>Temporarily configure coturn to accept a static username/password.
