The
rwho
command produces output similar to
who(1),
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 user 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.
The
rwho
protocol only supports up to eight character login names even though
OpenBSD
supports much longer ones.
Long login names will be truncated.
rwho
is unwieldy when the number of machines on the local net is large.
