Synopsis
rwhod
Description
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 3 minutes.
