rwho(1c)
NAME
rwho − who’s logged in on local machines
SYNTAX
rwho [ −ah ]
DESCRIPTION
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 5 minutes, then rwho assumes that 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 an hour or more, then the user will be omitted from the output of rwho.
OPTIONS
−aNormally, rwho omits users who have not typed to the system for an hour or more. If the −a flag is specified, these users will be listed.
−hNormally, rwho prints its output sorted by user name. If the −h flag is specified, than the results will be sorted by host name.
RESTRICTIONS
If a system exceeds 40 users logged in at once, the output of the rwho command will be incomplete. Users who login to a machine after that point will fail to appear in the output of the rwho command. This is due to the maximum size limit of an Ethernet packet, which is 1500 bytes, and the fact that the rwho daemon must broadcast its information in a single packet.
