One way to generate +the <code>static-auth-secret</code> is with <code>pwgen</code>:</p> +<pre><code class="language-sh">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 <code>coturn</code> to write logs somewhere. The +easiest way is normally to send them to the syslog:</p> +<pre><code class="language-sh">syslog +</code></pre> +<p>(in which case, the logs will be available via <code>journalctl -u coturn</code> on a +systemd system). Alternatively, <code>coturn</code> can be configured to write to a +logfile - check the example config file supplied with <code>coturn</code>.</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 + +# recommended additional local peers to block, to mitigate external access to internal services. +# https://www.rtcsec.com/article/slack-webrtc-turn-compromise-and-bug-bounty/#how-to-fix-an-open-turn-relay-to-address-this-vulnerability +no-multicast-peers +denied-peer-ip=0.0.0.0-0.255.255.255 +denied-peer-ip=100.64.0.0-100.127.255.255 +denied-peer-ip=127.0.0.0-127.255.255.255 +denied-peer-ip=169.254.0.0-169.254.255.255 +denied-peer-ip=192.0.0.0-192.0.0.255 +denied-peer-ip=192.0.2.0-192.0.2.255 +denied-peer-ip=192.88.99.0-192.88.99.255 +denied-peer-ip=198.18.0.0-198.19.255.255 +denied-peer-ip=198.51.100.0-198.51.100.255 +denied-peer-ip=203.0.113.0-203.0.113.255 +denied-peer-ip=240.0.0.0-255.255.255.255 + +# special case the turn server itself so that client->TURN->TURN->client flows work +# this should be one of the turn server's listening IPs +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.

It uses the (indentation-sensitive!) <a href="https://en.wikipedia.org/wiki/YAML">YAML</a> +format. The file contains further explanations.</p> +<p>Here are some hints how to configure eturnal on your <a href="https://github.com/processone/eturnal#configuration">host machine</a> +or when using e.g. <a href="https://eturnal.net/documentation/code/docker.html">Docker</a>. +You may also further deep dive into the <a href="https://eturnal.net/documentation/">reference documentation</a>.</p> +<p><code>eturnal</code> runs out of the box with the default configuration. To enable TURN and +to integrate it with your homeserver, some aspects in <code>eturnal</code>'s default configuration file +must be edited:</p> +<ol> +<li> +<p>Homeserver's <a href="../../usage/configuration/config_documentation.html#turn_shared_secret"><code>turn_shared_secret</code></a> +and eturnal's shared <code>secret</code> for authentication</p> +<p>Both need to have the same value. Uncomment and adjust this line in <code>eturnal</code>'s +configuration file:</p> +<pre><code class="language-yaml">secret: "long-and-cryptic" # Shared secret, CHANGE THIS. +</code></pre> +<p>One way to generate a <code>secret</code> is with <code>pwgen</code>:</p> +<pre><code class="language-sh">pwgen -s 64 1 +</code></pre> +</li> +<li> +<p>Public IP address</p> +<p>If your TURN server is behind NAT, the NAT gateway must have an external, +publicly-reachable IP address. <code>eturnal</code> tries to autodetect the public IP address, +however, it may also be configured by uncommenting and adjusting this line, so +<code>eturnal</code> advertises that address to connecting clients:</p> +<pre><code class="language-yaml">relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address. +</code></pre> +<p>If your NAT gateway is reachable over both IPv4 and IPv6, you may +configure <code>eturnal</code> to advertise each available address:</p> +<pre><code class="language-yaml">relay_ipv4_addr: "203.0.113.4" # The server's public IPv4 address. +relay_ipv6_addr: "2001:db8::4" # The server's public IPv6 address (optional). +</code></pre> +<p>When advertising an external IPv6 address, ensure that the firewall and +network settings of the system running your TURN server are configured to +accept IPv6 traffic, and that the TURN server is listening on the local +IPv6 address that is mapped by NAT to the external IPv6 address.</p> +</li> +<li> +<p>Logging</p> +<p>If <code>eturnal</code> was started by systemd, log files are written into the +<code>/var/log/eturnal</code> directory by default. In order to log to the <a href="https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html">journal</a> +instead, the <code>log_dir</code> option can be set to <code>stdout</code> in the configuration file.</p> +</li> +<li> +<p>Security considerations</p> +<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, <a href="https://eturnal.net/documentation/#blacklist">see also the official documentation</a>:</p> +<pre><code class="language-yaml">## Reject TURN relaying from/to the following addresses/networks: +blacklist: # This is the default blacklist. + - "127.0.0.0/8" # IPv4 loopback. + - "::1" # IPv6 loopback. + - recommended # Expands to a number of networks recommended to be + # blocked, but includes private networks. Those + # would have to be 'whitelist'ed if eturnal serves + # local clients/peers within such networks. +</code></pre> +<p>To whitelist IP addresses or specific (private) networks, you need to <strong>add</strong> a +whitelist part into the configuration file, e.g.:</p> +<pre><code class="language-yaml">whitelist: + - "192.168.0.0/16" + - "203.0.113.113" + - "2001:db8::/64" +</code></pre> +<p>The more specific, the better.</p> +</li> +<li> +<p>TURNS (TURN via TLS/DTLS)</p> +<p>Also consider supporting TLS/DTLS. To do this, adjust the following settings +in the <code>eturnal.yml</code> configuration file (TLS parts should not be commented anymore):</p> +<pre><code class="language-yaml">listen: + - ip: "::" + port: 3478 + transport: udp + - ip: "::" + port: 3478 + transport: tcp + - ip: "::" + port: 5349 + transport: tls + +## TLS certificate/key files (must be readable by 'eturnal' user!): +tls_crt_file: /etc/eturnal/tls/crt.pem +tls_key_file: /etc/eturnal/tls/key.pem +</code></pre> +<p>In this case, replace the <code>turn:</code> schemes in homeserver's <code>turn_uris</code> settings +with <code>turns:</code>. More is described <a href="../../usage/configuration/config_documentation.html#turn_uris">here</a>.</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> +<p>NB: If your TLS certificate was provided by Let's Encrypt, TLS/DTLS will +not work with any Matrix client that uses Chromium's WebRTC library.
