   netkit-rwho 0.17 (who is logged in on local machines)

   The rwho command produces output similar to who, but for all
   machines on the local network. If no report has been received from
   a machine for 11 minutes then rwho assumes the machine is down, and
   does not report users last known to be logged into that machine.
   If a users hasn't typed to the system for a minute or more, then
   rwho reports this idle time. If a user hasn't typed to the system
   for an hour or more, then the user will be omitted from the output
   of rwho unless the -a flag is given.
