RWHO(1) NetBSD General Commands Manual RWHO(1)
rwho -- who is logged in on local machines
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 the 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. -a Include all users. By default, if a user hasn't typed to the system for an hour or more, then the user will be omitted from the output. -H Write column headings above the regular output. -q ``Quick mode'': List only the names and the number of users currently logged on. When this option is used, all other options are ignored.

The rwho command appeared in 4.3BSD.
This is unwieldy when the number of machines on the local net is large. NetBSD 5.0_RC4 September 30, 2005 NetBSD 5.0_RC4
