NAME

rwho − who’s logged in on local machines

SYNOPSIS

rwho [ −a ]

DESCRIPTION

The rwho command produces output similar to who(1), but for all machines on your network.  If no report has been received from a machine for 11 minutes, rwho assumes the machine is down, and does not report users last known to be logged into that machine. 

If a user has not typed to the system for a minute or more, rwho reports this idle time.  If a user has not typed to the system for an hour or more, the user is omitted from the output of rwho unless the −a flag is given. 

The −a option reports all users whether or not they have typed to the system in the past hour.

SEE ALSO

NOTES

Does not work through gateways. 

This is unwieldy when the number of machines on the local net is large. 

The rwho service daemon, rwhod(1M), must be enabled on the remote system to broadcast status packets every 1 -3 minutes, and on local system to maintain the data bases for this command to return useful results.
