NAME

     gnugk -- The GNU Gatekeeper

SYNOPSIS

     gnugk [-hdrt] [-c filename] [-s section] [-i IP] [-l n] [-b n] [-u name] [-d name] [-rr] [-o filename] [--pid filename] [--core n]

DESCRIPTION

     The GNU Gatekeeper is an open-source project that implements a H.323 gatekeeper. A H.323 gatekeeper controls all H.323 clients in its zone.
     It allows you, among other things, to register devices, make calls, perform AAA (Authentication, Authorization and Auditing), manage configu-
     rations at runtime and traverse NAT.

OPTIONS

     The behavior of the gatekeeper is determined through command line options and the configuration file. Some command line options may override
     settings found in the configuration file. For example, the option -l overrides the setting "TimeToLive" in the configuration file.  Almost
     every option has a short and a long format, e.g., -c is the same as --config.

     -h --help
	      Show all available options and quit the program.

     -c --config filename
	     Specify the configuration file to use.

     -s --section section
	     Specify which main section to use in the configuration file. The default is [Gatekeeper::Main].

     -i --interface IP
	     Specify the IP address 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 to bind to a specified IP.

     -l --timetolive n
	     Specify the time-to-live timer (in seconds) for endpoint registration. This overrides the setting "TimeToLive" in the configuration
	     file. A detailed explanation can be found in the manual.

     -b --bandwidth n
	     Specify the total bandwidth available for the gatekeeper. Without specifying this option, bandwidth management is disabled by
	     default.

     --pid filename
	     Specify the pid file.  Only valid for Unix version.

     -u --user name
	     Run the gatekeeper process as this user. Only valid for Unix versions.

     --core n
	     (Unix only) Enable writing core dump files when the application crashes. A core dump file will not exceed n bytes in size. A special
	     constant "unlimited" may also be specified.

   Gatekeeper Mode
     The options in this subsection override the settings in the [RoutedMode] section of the configuration file.

     -d --direct
	     Use direct endpoint call signaling.

     -r --routed
	     Use gatekeeper routed call signaling.

     -rr --h245routed
	     Use gatekeeper routed call signaling and H.245 control channel.

   Debug Information
     -o --output filename
	     Write trace log to the specified file.

     -t --trace
	     Set trace verbosity. The more -t you add, the more verbose to output. For example, use -ttttt to set the trace level to 5.
