The rwho Command
The rwho command displays who is logged in to the local system. rwho displays output
similar to the HP-UX who command for all the machines on the local network running
the rwho daemon. If rwhod does not receive a report from a machine for 11 minutes,
rwho assumes that the machine is down and does not report the information about
last known users.
rwho’s output contains fields for the user name, the machine name, the user’s terminal
line, the time the user logged in, and the time period for which the user is idle. The idle
time is shown as hours:minutes.
If a user is inactive for 1 minute, rwho reports this as idle time. If a user is inactive for
1 hour or more, the user is omitted from rwho’s output unless the -a flag is specified.
An example rwho output is as follows:
joe_user machine1:tty0p1 Sep 12 13:28 :11
The output line indicates that joe_user has:
• Logged in to machine1.
• Terminal line tty0p1.
• Been logged in since September 12
th
at 13:28.
• Not typed anything into the machine for 11 minutes.
For detailed information on rwho, type man 1 rwho at the HP-UX prompt.
The rwhod Program
rwhod is the server that maintains the database used by the rwho and ruptime
commands. rwhod sends and receives status information from other nodes running
the rwhod daemon on the local network.
rwhod performs the following functions as an information sender:
• Periodically queries the state of the system.
• Constructs status messages.
• Broadcasts the status messages on the network.
