&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Rivendell has several daemons that run in the background helping things work.  &lt;br /&gt;
&lt;br /&gt;
The daemons can either be started during system boot up, via the /etc/&amp;#039;&amp;#039;&amp;#039;init.d&amp;#039;&amp;#039;&amp;#039; script, or they can be started as needed by the Rivendell programs using [http://en.wikipedia.org/wiki/Pluggable_Authentication_Modules PAM].  In the latter case, where the daemons are started as needed, the &amp;#039;&amp;#039;&amp;#039;pam_rd&amp;#039;&amp;#039;&amp;#039; PAM module can be used to ensure any old instances of the daemons are cleared out when a user logs in.&lt;br /&gt;
&lt;br /&gt;
The order the daemons start is important, as they depend on one another.  Here they are listed with the top most items started first:&lt;br /&gt;
&lt;br /&gt;
* 1) &amp;#039;&amp;#039;&amp;#039;jackd&amp;#039;&amp;#039;&amp;#039; [&amp;#039;&amp;#039;&amp;#039;optional&amp;#039;&amp;#039;&amp;#039;] (the jack audio connection kit daemon which allows for routing of audio from one application to another, only used if using the jack audio subsystem)&lt;br /&gt;
* 2) &amp;#039;&amp;#039;&amp;#039;caed&amp;#039;&amp;#039;&amp;#039; (the core audio engine daemon, which reads the audio files and plays them to the sound card)&lt;br /&gt;
* 3) &amp;#039;&amp;#039;&amp;#039;ripcd&amp;#039;&amp;#039;&amp;#039; (the rivendell interprocess communication daemon)&lt;br /&gt;
* 4) &amp;#039;&amp;#039;&amp;#039;rdcatchd&amp;#039;&amp;#039;&amp;#039; (a daemon to run batch jobs capturing and sending out audio)&lt;br /&gt;
* And then finall the Rivendell Applications can start (ex: rdairplay, rdlibrary)&lt;br /&gt;
