Name
rwhod
Synopsis
rwhod [options]TCP/IP command. System-status server that maintains the database used by the rwho and ruptime programs. Its operation is predicated on the ability to broadcast messages on a network. As a producer of information, rwhod periodically queries the state of the system and constructs status messages, which are broadcast on a network. As a consumer of information, it listens for other rwhod servers’ status messages, validates them, then records them in a collection of files located in the directory /var/spool/rwho. Messages received by the rwhod server are discarded unless they originated at an rwhod server’s port. Status messages are generated approximately once every three minutes.
Options

Use both broadcast and point-to-point interfaces. This is the default.
- -b

- -p
