<sect>Basic Gatekeeper Configuration
<p>
The behavior of the gatekeeper is completely determined by the command line
options and configuration file. Some command line options may override
the setting of the configuration file.
For example, the option <tt/-l/ overrides the setting <tt/TimeToLive/
in the configuration file.

<sect1>Command Line Options
<label id="commandline">
<p>
Almost every option has a short and a long format, e.g.,
<tt/-c/ is the same as <tt/--config/.
<p>
<sect2>Basic
<p>
<descrip>
<tag/<tt/-h  --help//
Show all available options and quit the program.
<tag/<tt/-c  --config filename//
Specify the configuration file to use.
<tag/<tt/-s  --section section//
Specify which main section to use in the configuration file. The default is [Gatekeeper::Main].
<tag/<tt/-i  --interface IP//
Specify the interface (IP number) that the gatekeeper listens to.
You should leave out this option to let the gatekeeper automatically determine
the IP it listens to, unless you want the gatekeeper only binds to
a specified IP.
<tag/<tt/-l  --timetolive n//
Specify the time-to-live timer (in seconds) for endpoint registration.
It overrides the setting <tt/TimeToLive/ in the configuration file.
See <ref id="ttl" name="there"> for detailed explanations.
<tag/<tt/-b  --bandwidth n//
Specify the total bandwidth available for the gatekeeper.
Without specifying this option, the bandwidth management
is disable by default.
<tag/<tt/--pid filename//
Specify the pid file, only valid for Unix version.
<tag/<tt/-u  --user name//
Run the gatekeeper process as this user. Only valid for Unix versions.
<tag/<tt/--core n//
(Unix only) Enable writting core dump files when the application crashes. A core
dump file will not exceed n bytes in size. A special constant "unlimited"
may be used to not enforce any particular limit.
</descrip>

<sect2>Gatekeeper Mode
<p>
The options in this subsection override the settings in the
<ref id="routed" name="[RoutedMode] section"> of the configuration file.
<descrip>
<tag/<tt/-d  --direct//
Use direct endpoint call signalling.
<tag/<tt/-r  --routed//
Use gatekeeper routed call signalling.
<tag/<tt/-rr  --h245routed//
Use gatekeeper routed call signalling and H.245 control channel.
</descrip>

<sect2>Debug Information
<p>
<descrip>
<tag/<tt/-o  --output filename//
Write trace log to the specified file.
<tag/<tt/-t  --trace//
Set trace verbosity. The more <tt/-t/ you add, the more verbose to output.
For example, use <tt/-ttttt/ to set the trace level to 5.
</descrip>
