Limit user connection

[Vogra]

Hi All.
how can I limit the number of connection by user at same time - HPUX10.20 ?
Thanx.

The only thing I can think of is to put something into one of the . files (.cshrc, .login, .profile, etc.) for each user and check to see if they are already logged in, if so, how many times. If they are logged in too many times, then tell them they aren't allowed any more logins and do an exit.

Something like this:

#!/bin/sh

user=`echo $LOGNAME`
num_logins=`who | grep $user | wc -l`

if ( $num_logins > 2 ) then
echo "You have already have 2 sessions. You can't login anymore"
sleep 15
exit
fi
