<p>This section contains server level settings that, in general, do not need to be changed.  Only modify this section if you are know what you are doing.

<h4>clients</h4>
<div class=indentedbox>
vanguardist's avatar
vanguardist committed
41
Total number of concurrent clients supported by the server.  Listeners are considered clients, but so is accesses to any static content (i.e. fileserved content) and also any requests to gather stats.  These are max *concurrent* connections for the entire server (not per mountpoint).
42 43 44
</div>
<h4>sources</h4>
<div class=indentedbox>
vanguardist's avatar
vanguardist committed
45
Maximum number of connected sources supported by the server.
46 47 48 49 50 51 52 53 54 55 56 57 58 59 60
</div>
<h4>threadpool</h4>
<div class=indentedbox>
This is the number of threads that are started to handle client connections.  You may need to increase this value if you are running a high traffic stream.  This recommended value is for a small to medium traffic server.
</div>
<h4>queue-size</h4>
<div class=indentedbox>
This is the maximum size (in bytes) of a client (listener) queue.  A listener may temporarily lag behind due to network congestion and in this case an internal queue is maintained for each listener.  If the queue grows larger than this config value, then the listener will be removed from the stream.
</div>
<h4>client-timeout</h4>
<div class=indentedbox>
This does not seem to be used.
</div>
<h4>header-timeout</h4>
<div class=indentedbox>
vanguardist's avatar
vanguardist committed
61
The maximum time (in seconds) to wait for a request to come in once the client has made a connection to the server.  In general this value should not need to be tweaked.
62 63 64 65 66
</div>
<h4>source-timeout</h4>
<div class=indentedbox>
If a connected source does not send any data within this timeout period (in seconds), then the source connection will be removed from the server.
</div>
67 68 69 70
<h4>burst-on-connect</h4>
<div class=indentedbox>
With this enabled, a connecting client will be sent a burst of audio data from the stream.  This will have the effect of reducing the startup time for the stream from the perspective of the listener.  This is due to the fact that most media players have local buffers that must be filled before the stream begins to play.  This may introduce a small latency in the stream (difference in time between when the source plays a clip and the listener hears a clip).  If this latency is important to you, then you can disable this feature.  The latency is bitrate-dependent, but as an example, for a 128kbps stream, the latency between the source and the player is ~ 1.5 secs WITHOUT burst on connect, and WITH burst on connect the latency is 3 secs.

<p>This section contains the server's relay settings. There are two types of relays: a "Master server relay" or a "Specific Mountpoint relay."  A Master server relay is only supported between icecast2 servers and is used to relays all mountpoints on a remote icecast2 server.

<h3>Master Relay</h3>

The following diagram shows the basics of doing a Master relay.  Note that Server 1 is configured with the &lt;master-server&gt;, &lt;master-server-port&gt;, etc settings and Server 2 is the server from which Server 1 will pull all attached mountpoints and relay them.  Using a Master Server relay, ALL mountpoints on Server 2 will be relayed.  If only specific mountpoints need to be relayed, then you must configure Server 1 as a "Specific Mountpoint Relay".  Both Master server relays and Specific Mountpoint relays begin their "relaying" when the Server is started.

A server is configured as a Master Server relay by specifying the &lt;master-server&gt;, &lt;master-server-port&gt;,&lt;master-update-interval&gt;,&lt;master-password&gt; values in the config file.  The server that is being relayed does not need any special configuration.

<h3>Specific Mountpoint Relay</h3>

The following diagram shows the basics of doing a Specific Mountpoint relay.  Note that Server 1 is configured with the &lt;relay&gt; settings and Server 2 is the server from which Server 1 will pull the specified mountpoint(s) and relay them.  Using a Specific Mountpoint Relay, only those mountpoints specified on Server 1 will be relayed from Server 2.

     settings 

</pre>

Specific Mountpoint Relays can be configured to relay from an Icecast 2 server, as well as Icecast 1.x and Shoutcast.
A server is configured as a Specific Mountpoint Server relay by specifying a &lt;relay&gt; XML chunk in the config file for each mountpoint to be relayed.  The server that is being relayed does not need any special configuration.

        &lt;server&gt;127.0.0.1&lt;server&gt;

If you are relaying a Shoutcast stream, you need to specify this indicator to also relay the metadata (song titles) that is part of the Shoutcast stream (1=enabled, 0=disabled).

This specifies a mountpoint that is used in the case of a source disconnect.  If listeners are connected to the mount specified by the &lt;mount-name&gt; config value, then if the source is disconnected; all currently connected clients will be moved to the fallback-mount.

<h4>pidfile</h4>

<h4>webroot</h4>
<div class=indentedbox>
This path specifies the base directory used for all static file requests.  This directory can contain all standard file types (including mp3s and ogg vorbis files).  For example, if webroot is set to /var/share/icecast2, and a request for http://server:port/mp3/stuff.mp3 comes in, then the file /var/share/icecast2/mp3/stuff.mp3 will be served.
</div>
<h4>adminroot</h4>
<div class=indentedbox>
This path specifies the base directory used for all admin requests.  More specifically, this is used to hold the XSLT scripts used for the web-based admin interface.  The admin directory contained within the icecast distribution contains these files.
</div>
<h4>alias source="/foo" dest="/bar"</h4>

Aliases are used to provide a way to create multiple mountpoints that refer to the same mountpoint.

<p>This section contains information relating to logging within icecast.  There are two logfiles currently generated by icecast, an error.log (where all log messages are placed) and an access.log (where all stream/admin/http requests are logged).
</p>
<p>Note that on non-win32 platforms, a HUP signal can be sent to icecast in which the log files are re-opened for appending giving the ability move/remove the log files.
<h4>accesslog</h4>
<div class=indentedbox>
Into this file, all requests made to the icecast2 will be logged.  This file is relative to the path specified by the &lt;logdir&gt; config value.
</div>
<h4>errorlog</h4>
<div class=indentedbox>
All icecast generated log messages will be written to this file.  If the loglevel is set too high (Debug for instance) then this file can grow fairly large over time.  Currently, there is no log-rotation implemented.
</div>
<h4>loglevel</h4>
<div class=indentedbox>
Indicates what messages are logged by icecast.  Log messages are categorized into one of 4 types, Debug, Info, Warn, and Error.<br><br>The following mapping can be used to set the appropraite value :
</div>
<br>
<br>
<li>loglevel = 4 - Debug, Info, Warn, Error messages are printed
<li>loglevel = 3 - Info, Warn, Error messages are printed
<li>loglevel = 2 - Warn, Error messages are printed
