+
+ <p><a href="https://github.com/coturn/coturn">Coturn</a> is a libre <strong>STUN</strong> and <strong>TURN</strong> server software that allows users of chat protcols (Such as <a href="xmpp.html">XMPP</a> and <a href="matrix.html">Matrix</a>) to perform WebRTC <strong>voice and video calls</strong> despite them being behind NATs.</p>
+
+ <p>Almost every self-hosted voice and video conferencing program (such as <a href="jitsi.html">Jitsi</a> and <a href="nextcloud.html">Nextcloud's</a> Talk app) will <strong>require</strong> Coturn or some other equivalent turnserver to function properly.</p>
+
+ <h2>Installation</h2>
+
+ <p>Coturn is available in the Debian repositories:</p>
+
+ <pre><code>apt install coturn</code></pre>
+
+ <h2>Configuration</h2>
+
+ <h3>Base configuration</h3>
+
+ <p>Coturn's configuration file is <code>/etc/turnserver.conf</code>. There are a few aspects that need to be changed in order to get a fully-functioning turnserver.</p>
+
+ <p>Here is an example of some sane defaults:</p>
+
+ <pre><code>server-name=<strong>turn.example.org</strong>
+realm=<strong>turn.example.org</strong>
+listening-ip=<strong>your_public_ip</strong>
+
+listening-port=3478
+min-port=10000
+max-port=20000
+
+## The "verbose" option is useful for debugging issues
+verbose</code></pre>
+
+ <h3>Authentication</h3>
+
+ <p>There are two options for authentication on a turnserver:</p>
+ <ol>
+ <li><strong>Usernames</strong> and <strong>passwords,</strong></li>
+ <li>or <strong>authentication secrets.</strong></li>
+ </ol>
+
+ <p>Depending on what self-hosted service is being used in conjunction with Coturn, you may need one or the other of these two options.</p>
+
+ <h4>Usernames and Passwords</h4>
+
+ <p>To utilize username and password authentication with Coturn, add the following configuration in <code>turnserver.conf</code>:</p>
+
+ <pre><code>lt-cred-mech
+user=<strong>username</strong>:<strong>password</strong></code></pre>
+
+ <h4>Authentication Secrets</h4>
+
+ <p>To utilize authentication secrets with Coturn, add the following configuration in <code>turnserver.conf</code>:</p>
+
+ <pre><code>use-auth-secret
+static-auth-secret=<strong>your_auth_secret</strong></code></pre>
+
+ <h2>TURNS (TLS Encryption)</h2>
+
+ <p>Some self-hosted services (such as Matrix and XMPP) may support the use of <strong>TURNS:</strong> An encrypted version of TURN, which allows for WebRTC connections to be established with the use of an encrypted TLS tunnel, just like HTTPS allows for encrypted viewing of websites.</p>
+
+ <p>To utilize TURNS, certificates need to be declared for <strong>turn.example.org</strong> in <code>turnserver.conf</code>:
+ <pre><code>cert=/etc/letsencrypt/live/<strong>turn.example.org</strong>/fullchain.pem
+pkey=/etc/letsencrypt/live/<strong>turn.example.org</strong>/privkey.pem</pre></code>
+
+ <h2>Starting Coturn</h2>
+
+ <p>After all configuration changes are complete, Coturn can be started with its systemd daemon:</p>
+
+ <pre><code>systemctl restart coturn</code></pre>
+
+ <p>Congratulations! You've successfully setup a Coturn server!</p>

+
+ <img class=titleimg src="pix/xmpp.svg" alt="XMPP logo and icon">
+
+ <p>
+ <a href="https://ejabberd.im">Ejabberd</a> is a server for the XMPP protocol written in Erlang.
+ It's easier to configure and setup than <a href="xmpp.html">Prosody</a> due to having most of its modules built-in and pre-configured by default.
+ </p>
+
+ <h2>Prerequisites</h2>
+ <h3>Subdomains</h3>
+ <p>
+ Ejabberd presumes that you have already created all the <strong>required and optional subdomains</strong> for its operation prior to running it.
+ </p>
+
+ <p>Depending on the usecase, you may need any or all of the following domains for XMPP functionality:<p>
+ <ul>
+ <li><strong>example.org</strong> - Your XMPP hostname</li>
+ <li><strong>conference.example.org</strong> - For Multi User Chats (MUCs)</li>
+ <li><strong>upload.example.org</strong> - For file upload support</li>
+ <li><strong>proxy.example.org</strong> - For SOCKS5 proxy support</li>
+ <li><strong>pubsub.example.org</strong> - For publish-subscribe support</li>
+ </ul>
+
+ <p>This guide will assume <strong>all these subdomains</strong> have been created.</p>
+
+ <h2>Installation</h2>
+ <p>Ejabberd is available in the Debian repositories:</p>
+ <pre><code>apt install ejabberd</code></pre>
+
+ <h2>Configuration</h2>
+ <p>The ejabberd server is configured in <code>/etc/ejabberd/ejabberd.yml</code>. Changes are only applied by restarting the ejabberd daemon in systemd:</p>
+ <pre><code>systemctl restart ejabberd</code></pre>
+
+ <h3>Hostnames</h3>
+ <p>The <strong>XMPP hostname</strong> is specified in the <code>hosts</code> section of <code>ejabberd.yml</code>:</p>
+
+ <pre><code>hosts:
+ - <strong>example.org</strong></code></pre>
+
+ <h3>Certificates</h3>
+ <p>Unlike <a href="https://prosody.im">Prosody,</a> ejabberd doesn't come equipped with a script that can automatically copy over the relevant certificates to a directory where the ejabberd user can read them.</p>
+
+ <p>One way of organizing certificates for ejabberd is to have them stored in <code>/etc/ejabberd/certs</code>, with each domain having a separate directory for both the fullchain cert and private key.</p>
+
+ <p>Using certbot, this process can be easily automated with this one-liner:</p>
+ <pre><code>$DOMAIN=<strong>subdomain.example.org</strong>
+certbot --nginx -d $DOMAIN certonly; mkdir /etc/ejabberd/certs/$DOMAIN; cp /etc/letsencrypt/live/$DOMAIN/fullchain.pem /etc/ejabberd/certs/$DOMAIN; cp /etc/letsencrypt/live/$DOMAIN/privkey.pem /etc/ejabberd/certs/$DOMAIN</code></pre>
+
+ <p>This should be ran with your XMPP hostname <strong>(example.org)</strong> and repeated for all your desired subdomains.</p>
+
+ <p>To enable the use of all these certificates in ejabberd, the following configuration is necessary:</p>
+
+ <pre><code>certfiles:
+ - "/etc/ejabberd/certs/*/*.pem"</code></pre>
+
+ <h3>Admin User</h3>
+
+ <p>The <strong>admin user</strong> can be specified in <code>ejabberd.yml</code> under the <code>acl</code> section:</p>
+
+ <pre><code>acl:
+ admin:
+ user: <strong>admin</strong></code></pre>
+
+ <p>This would make <strong>admin@example.org</strong> the user with administrator privileges.</p>
+
+ <h3>Message Archives</h3>
+
+ <p>The ejabberd server supports keeping archives of messages through its <code>mod_mam</code> module. This can be enabled by uncommenting the following lines:</p>
+
+ <pre><code>mod_mam:
+ assume_mam_usage: true
+ default: always</code></pre>
+
+ <h2>Database</h2>
+ <h3>Why use a database?</h3>
+ <p>In the <code>mod_mam</code> section of the ejabberd config file, the following message is in comments:</p>
+
+ <pre><code>mod_mam:
+ ## Mnesia is limited to 2GB, better to use an <strong>SQL backend</strong>
+ ## For small servers SQLite is a good fit and is very easy
+ ## to configure. Uncomment this when you have SQL configured:
+ ## <strong>db_type: sql</strong></code></pre>
+
+ <p>As these comments imply, an <strong>SQL backend</strong> is strongly recommended if you wish to use your ejabberd server for anything more than just testing. Ejabberd supports <strong>MySQL, SQLite</strong> and <strong>PostgreSQL.</strong></p>
+
+ <p>While all of those are suitable choices, the best database system to use is PostgreSQL. It's the same database backend used by <a href="peertube.html">PeerTube</a> and <a href="matrix.html">Matrix,</a> making it the most convenient option if you're already running those too.</p>
+
+ <h3>Installing PostgreSQL</h3>
+
+ <p>PostgreSQL is available in the Debian repositories:</p>
+ <pre><code>apt install postgresql</code></pre>
+
+ <p>Start the PostgreSQL daemon to begin using it:</p>
+ <pre><code>systemctl start postgresql</code></pre>
+
+ <h3>Creating the Database</h3>
+ <p>To create the database, first create a PostgreSQL user for ejabberd:</p>
+
+ <pre><code>su -c "createuser --pwprompt ejabberd" postgres</code></pre>
+
+ <p>Then, create the database and make <code>ejabberd</code> its owner:</p>
+
+ <pre><code>su -c "psql -c 'CREATE DATABASE ejabberd OWNER ejabberd;'" postgres</code></pre>
+
+ <h3>Importing Database Scheme</h3>
+
+ <p>Ejabberd doesn't create the database scheme by default; It has to be imported into the database before use.</p>
+
+ <pre><code>su -c "curl -s https://raw.githubusercontent.com/processone/ejabberd/master/sql/pg.sql | psql ejabberd" postgres</code></pre>
+
+ <h3>Configuring ejabberd to use PostgreSQL</h3>
+ <p>Finally, add the following configuration to <code>ejabberd.yml</code>:</p>
+
+ <pre><code>sql_type: pgsql
+sql_server: "localhost"
+sql_database: <strong>"ejabberd"</strong>
+sql_username: <strong>"ejabberd"</strong>
+sql_password: <strong>"psql_password"</strong></code></pre>
+
+ <p>Once you've ensured your database name, username and password are all correct, enable SQL storage for <code>mod_mam</code>:</p>
+
+ <pre><code>mod_mam:
+ ## (Other parameters)
+ db_type: <strong>sql</strong></code></pre>
+
+ <h2>Using ejabberd</h2>
+ <h3>Registering the Admin User</h3>
+ <p>To begin using ejabberd, firstly start the ejabberd daemon:</p>
+
+ <pre><code>systemctl restart ejabberd</code></pre>
+
+ <p>Then, using <code>ejabberdctl</code> as the ejabberd user, register the admin user which is set in <code>ejabberd.yml</code>:</p>
+
+ <pre><code>su -c "ejabberdctl register <strong>admin example.org password</strong>" ejabberd</code></pre>
+
+ <p>This will create the user <strong>admin@example.org.</strong></p>
+
+ <h3>Using the Web Interface</h3>
+
+ <p>By default, ejabberd has a web interface accessible from <strong>http://example.org:5280/admin</strong>. When accessing this interface, you will be prompted for the admin credentials:</p>
+
+ <img src="pix/ejabberd-login.jpg" height="260px">
+
+ <p>After signing in with the admin credentials, you will be able to manage your ejabberd server from this web interface:</p>
+
+ <img src="pix/ejabberd-admin.jpg" height="300px">
+
+ <h2>TURN & STUN for Calls</h2>
+
+ <p>Ejabberd supports the <strong>TURN</strong> and <strong>STUN</strong> protocols to allow internet users behind NATs to perform voice and video calls with other XMPP users.</p>
+
+ <p>Firstly, setup a TURN and STUN server with <a href="coturn.html">Coturn,</a> using an <strong>authentication secret.</strong></p>
+
+ <p>Then, edit <code>mod_stun_disco</code> to contain the appropriate information for your turnserver:</p>
+
+ <pre><code> mod_stun_disco:
+ secret: <strong>"your_auth_secret"</strong>
+ services:
+ -
+ host: <strong>turn.example.org</strong>
+ type: stun
+ -
+ host: <strong>turn.example.org</strong>
+ type: turn</code></pre>
+
+<p>And with that, you've successfully setup your ejabberd XMPP server!</p>
