rdc(1M)

Specifies that rdc does not change the kernel forwarding table while running ramd and routing daemons. This option is useful to test the daemons, when the daemons should operate as a route server that does not forward.

Suppresses the stderr messages of ramd and routing daemons. This option can be used to suppress informational messages that are normally printed to the standard output, and the log error messages through syslogd(1M).

Specifies the time in seconds for which rdc waits to start, stop, reconfigure and terminate daemons. By default, this value is set to 10 seconds.

Specifies the maximum size of a core dump produced by the routing daemons invoked using rdc.

Specifies the maximum size of a file produced or created by the routing daemons invoked using rdc.

Sends an abort signal to the requested daemon and terminates the daemon with a core dump. The core files are generated in the file /var/tmp/*/core, where * can be ramd, ripngd, bgpd or isisd.

Sends a signal to the requested daemon to dump its current state into the /var/tmp/*/*.dump, where * is one of the routing daemons.

Kills the daemon abruptly. This command is used when the daemon hangs.

Sends SIGHUP signal to the requested daemon to reread its configuration file and reconfigure its current state.

Sends SIGTERM signal to the requested daemon to terminate gracefully.

Sends SIGUSR1 signal to the daemon to toggle the trace. If tracing is enabled, this command causes tracing to be suspended and the trace file to be closed. If tracing is disabled, the trace file is reopened and tracing initiated. This is useful to move the trace files. If ramd or the routing daemon tracing is modified using this command and the daemons are reconfigured with the trace options, the effect on tracing is with respect to the configuration file.

Sends SIGUSR2 signal to ramd to recheck the interface configuration. ramd periodically checks the kernel interface configuration for any changes. This command can be used to force the daemon to check the interface status immediately. Currently, the only valid argument for this command is ram, for checking on ramd.

createconf command of rdc is used to create this configuration file.

When rdc must install a new configuration file using the createconf command, the existing /etc/ramd.conf file is renamed as /etc/ramd.conf.prev file.

When rdc creates a new configuration file, using the createconf command, the existing /etc/ramd.conf, file is renamed as /etc/ramd.conf.prev and the existing /etc/ramd.conf.prev is renamed as /etc/ramd.conf.prev.old file.

Checks /etc/ramd.conf for syntax errors. This is done after changes are made to the configuration file and before reconfiguring the routing daemons. The system administrator use this command to ensure that there are no syntax errors in the configuration file, which can otherwise terminate the daemons on reconfiguration.

Checks the /etc/ramd.conf.new file for syntax errors.

Renames the /etc/ramd.conf.new file to /etc/ramd.conf, retaining the older versions of the configuration files. This operation fails if /etc/ramd.conf.new does not exist.

Replaces the old configuration file /etc/ramd.conf.old to /etc/ramd.conf. This command fails, if the /etc/ramd.conf.old file does not exist or if the file /etc/ramd.conf.old is of zero length, or if the backout command deletes an existing, non-zero length /etc/ramd.conf.new file.

Performs a backout operation even if the /etc/ramd.conf.new file exists and is of non-zero length.

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

Creates a new configuration file, /etc/ramd.conf.new with zero length. The file mode is set to 664, owner root and group trusted non-root user. This allows a trusted non-root user to install a new configuration file.

Starts ramd. The command returns an error if ramd is already running. It invokes ramd and waits for the time period specified with -t option. 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. Starting ramd invokes all the configured protocols in the configuration file of ramd.

Determines if daemons are currently running. rdc exits with a zero status if the daemon is running and with a non-zero value if the daemons are not running.

Stops the requested routing daemon gracefully. Stopping ramd stops all the daemons.

Restarts the requested daemon. rdc reports an error, if there is a failure.
