|
||
<p>The following sections describe how to install <a href="https://github.com/processone/eturnal">eturnal</a>
|
||
(which implements the TURN REST API).</p>
|
||
<h2 id="eturnal-setup"><a class="header" href="#eturnal-setup"><code>eturnal</code> setup</a></h2>
|
||
<h3 id="initial-installation"><a class="header" href="#initial-installation">Initial installation</a></h3>
|
||
<p>The <code>eturnal</code> TURN server implementation is available from a variety of sources
|
||
such as native package managers, binary packages, installation from source or
|
||
<a href="https://eturnal.net/documentation/code/docker.html">container image</a>. They are
|
||
all described <a href="https://github.com/processone/eturnal#installation">here</a>.</p>
|
||
<p>Quick-Test instructions in a <a href="https://github.com/processone/eturnal/blob/master/QUICK-TEST.md">Linux Shell</a>
|
||
or with <a href="https://github.com/processone/eturnal/blob/master/docker-k8s/QUICK-TEST.md">Docker</a>
|
||
are available as well.</p>
|
||
<h3 id="configuration"><a class="header" href="#configuration">Configuration</a></h3>
|
||
<p>After installation, <code>eturnal</code> usually ships a <a href="https://github.com/processone/eturnal/blob/master/config/eturnal.yml">default configuration file</a>
|
||
here: <code>/etc/eturnal.yml</code> (and, if not found there, there is a backup file here:
|
||
<code>/opt/eturnal/etc/eturnal.yml</code>). 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.

- recommended # Expands to a number of networks recommended to be

|
||
</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. This
|
||
currently includes Element Android & iOS; for more details, see their
|
||
<a href="https://github.com/vector-im/element-android/issues/1533">respective</a>
|
||
<a href="https://github.com/vector-im/element-ios/issues/2712">issues</a> as well as the underlying
|
||
<a href="https://bugs.chromium.org/p/webrtc/issues/detail?id=11710">WebRTC issue</a>.
|
||
Consider using a ZeroSSL certificate for your TURN server as a working alternative.</p>
|
||
</li>
|
||
<li>
|
||
<p>Firewall</p>
|
||
<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>Reload/ restarting <code>eturnal</code></p>
|
||
<p>Changes in the configuration file require <code>eturnal</code> to reload/ restart, this
|
||
can be achieved by:</p>
|
||
<pre><code class="language-sh">eturnalctl reload
|
||
</code></pre>
|
||
<p><code>eturnal</code> performs a configuration check before actually reloading/ restarting
|
||
and provides hints, if something is not correctly configured.</p>
|
||
</li>
|
||
</ol>
|
||
<h3 id="eturnalctl-opterations-script"><a class="header" href="#eturnalctl-opterations-script">eturnalctl opterations script</a></h3>
|
||
<p><code>eturnal</code> offers a handy <a href="https://eturnal.net/documentation/#Operation">operations script</a>
|
||
which can be called e.g. to check, whether the service is up, to restart the service,
|
||
to query how many active sessions exist, to change logging behaviour and so on.</p>
|
||
<p>Hint: If <code>eturnalctl</code> is not part of your <code>$PATH</code>, consider either sym-linking it (e.g. ´ln -s /opt/eturnal/bin/eturnalctl /usr/local/bin/eturnalctl´) or call it from the default <code>eturnal</code> directory directly: e.g. <code>/opt/eturnal/bin/eturnalctl info</code></p>
