We wanted something a bit more user explicit (log out idle users but not the boss(s)). The list of users below are exempt. Set this script in crontab to run every 10 minutes. With an idle of time of 30, the idled sessions will be no more than 39 minutes idle. Here is our script;

#! /usr/bin/awk -f

BEGIN {
system("who -u | sort +5 > /tmp/loginfile");
system("echo User Sessions Killed > /tmp/killedlogins");
system("echo `date` >> /tmp/killedlogins");
while (getline = 1) || (timearray[2] >= 30)) &&
($1 != "root") &&
($1 != "user2") &&
($1 != "user2") &&
($1 != "user4") &&
($1 != "lastuser")) { {
system("ps -ef | grep " $1 " | awk '{print $2}' | xargs kill -KILL");
print $1, "[Idle " $6 "] Session terminated from " $8 >> "/tmp/killedlogins";
};
};
};
}
