sorting data from who by IP
Hello. I have an RS/6000 running AIX 4 and I need to be able to see if there are any users that are logged on more than once from the same terminal so I can kick them off to make room for other terminals. 64 connections is the limit. Currently I am doing this:
who | more
and then manually looking for duplicate IP's and then doing
ps -t pts/whatever or tty
to find the PID then killing the PID. Is there an easier and faster way of doing this? Thanks
-paul

rusers
RUSERS(1) BSD General Commands Manual RUSERS(1)
NAME
rusers -- who is logged in to machines on local network
SYNOPSIS
rusers [-al] [host ...]
DESCRIPTION
The rusers command produces output similar to who(1), but for the list of hosts or all machines on the local network. For each host respond-
ing to the rusers query, the hostname with the names of the users currently logged on is printed on each line. The rusers command will wait
for one minute to catch late responders.
The following options are available:
-a Print all machines responding even if no one is currently logged in.
-l Print a long format listing. This includes the user name, host name, tty that the user is logged in to, the date and time the user
logged in, the amount of time since the user typed on the keyboard, and the remote host they logged in from (if applicable).
DIAGNOSTICS
rusers: RPC: Program not registered The rpc.rusersd(8) daemon has not been started on the remote host.
rusers: RPC: Timed out A communication error occurred. Either the network is excessively congested, or the rpc.rusersd(8) daemon has termi-
nated on the remote host.
rusers: RPC: Port mapper failure - RPC: Timed out The remote host is not running the portmapper (see rpcbind(8)), and cannot accommodate any
RPC-based services. The host may be down.
SEE ALSO
rwho(1), users(1), who(1), rpc.rusersd(8), rpcbind(8)
HISTORY
The rusers command appeared in Sun-OS.
BUGS
The sorting options are not implemented.
