gdc(1M)

Run without changing the kernel forwarding table. Useful for testing, and when operating as a route server which does no forwarding.

Run quietly. With this option informational messages which are normally printed to the standard output are suppressed and error messages are logged via syslogd instead of being printed to the standard error output. This is often convenient when running gdc from a shell script.

Specifies the time in seconds which gdc will spend waiting for gated to complete certain operations, in particular at termination and startup. By default this value is set to 10 seconds.

Sets the maximum size of a core dump a gated started with gdc will produce. Useful on systems where the default maximum core dump size is too small for gated to produce a full core dump on errors.

Sets the maximum file size a gated started with gdc will produce. Useful on systems where the default maximum file dump size is too small for gated to produce a full state dump when requested.

Sets the maximum size of the data segment of a gated started with gdc. Useful on systems where the default data segment size is too small for gated to run.

Sets the maximum size of stack of a gated started with gdc. Useful on systems where the default maximum stack size is too small for gated to run.

Sends an abort signal to gated, causing it to terminate with a core dump.

Signal gated to dump its current state into the file /usr/tmp/gated_dump.

Signal gated to recheck the interface configuration. gated normally does this periodically in any event, but the facility can be used to force the daemon to check interface status immediately when changes are known to have occurred.

Cause gated to terminate ungracefully. Normally useful when the daemon has hung.

Signal gated to reread its configuration file, reconfiguring its current state as appropriate.

Signal gated to terminate after shutting down all operating routing protocols gracefully. Executing this command a second time should cause gated to terminate even if some protocols have not yet fully shut down.

If gated is currently tracing to a file, cause tracing to be suspended and the trace file to be closed. If gated tracing is current suspended, cause the trace file to be reopened and tracing initiated. This is useful for moving trace files.

The new configuration file. When gdc is requested to install a new configuration file, this file is renamed /etc/gated.conf.

The old configuration file. When gdc is requested to install a new configuration file, the previous /etc/gated.conf is renamed to this name.

The really old configuration file. gdc retains the previous old configuration file under this name.

Check /etc/gated.conf for syntax errors. This is usefully done after changes to the configuration file but before sending a reconfig signal to the currently running gated, to ensure that there are no errors in the configuration which would cause the running gated to terminate on reconfiguration. When this command is used, gdc issues an informational message indicating whether there were parse errors or not, and if so saves the error output in a file for inspection.

Like checkconf except that the new configuration file, /etc/gated.conf+, is checked instead.

Move the /etc/gated.conf+ file into place as /etc/gated.conf, retaining the older versions of the file as described above. gdc will decline to do anything when given this command if the new configuration file doesn't exist or otherwise looks suspect.

Rotate the configuration files in the newer direction, in effect moving the old configuration file to /etc/gated.conf. The command will decline to perform the operation if /etc/gated.conf- doesn't exist or is zero length, or if the operation would delete an existing, non-zero length /etc/gated.conf+ file.

Perform a backout operation even if /etc/gated.conf+ exists and is of non-zero length.

Set all configuration files to mode 664, owner root, group gdmaint. This allows a trusted non-root user to modify the configuration files.

If /etc/gated.conf+ does not exist, create a zero length file with the file mode set to 664, owner root, group gdmaint. This allows a trusted non-root user to install a new configuration file.

Determine if gated is currently running. This is done by checking to see if gated has a lock on the file containing its pid, if the pid in the file is sensible and if there is a running process with that pid. Exits with zero status if gated is running, non-zero otherwise.

Start gated. The command returns an error if gated is already running. Otherwise it executes the gated binary and waits for up to the delay interval (10 seconds by default, as set with the -t option otherwise) until the newly started process obtains a lock on the pid file. A non-zero exit status is returned if an error is detected while executing the binary, or if a lock is not obtained on the pid file within the specified wait time.

Stop gated, gracefully if possible, ungracefully if not. The command returns an error (with non-zero exit status) if gated is not currently running. Otherwise it sends a terminate signal to gated and waits for up to the delay interval (10 seconds by default, as specified with the -t option otherwise) for the process to exit. Should gated fail to exit within the delay interval it is then signaled again with a second terminate signal. Should it fail to exit by the end of the second delay interval it is signaled for a third time with a kill signal. This should force immediate termination unless something is very broken. The command terminates with zero exit status when it detects that gated has terminated, non-zero otherwise.

If gated is running it is terminated via the same procedure as is used for the stop command above. When the previous gated terminates, or if it was not running prior to command execution, a new gated process is executed using the procedures described for the start command above. A non-zero exit status is returned if any step in this procedure appears to have failed.
