gnugk - Open H323 Gatekeeper - The GNU Gatekeeper


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


The GNU Gatekeeper is an open-source project that implements a H.323 gatekeeper. A H323 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 configurations at runtime and traverse NAT.


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. Fl h -help
 Show all available options and quit the program.  Fl c -config Ar filename Specify the configuration file to use. Fl s -section Ar section Specify which main section to use in the configuration file. The default is [Gatekeeper::Main]. Fl i -interface Ar 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. Fl l -timetolive Ar 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. Fl b -bandwidth Ar n Specify the total bandwidth available for the gatekeeper. Without specifying this option, bandwidth management is disabled by default. Fl -pid Ar filename Specify the pid file. Only valid for Unix version. Fl u -user Ar name Run the gatekeeper process as this user. Only valid for Unix versions. Fl -core Ar 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.
