My users keep forgetting to logout their terminals and often stay logged in
to my RS6K server. Besides being a security risk, this is not allowing
backups to run at night.

Anybody knows a way to terminate AIX 4.3 telnet sessions after a certain
idle time?

Or, what would be the command to kill all non-root processes that can be
places in Cron before backup starts?

Thanks in advance.

this might help

Thanks Mark.. That was helpful. I'm not so good at scripts but I'll keep
trying.

I apreciate it.

You might want to do what some people do and have Cron restart the
machine and then do the backup. This will help if a session gets locked
up or is still running and not showing as being idle.

Mark,

export TMOUT=300 worked if a user was at a shell prompt, however, it
wouldn't if a program was left running on the user's telnet screen which is
the case in my situation.

Thanks anyway.

Thanks Michael, that's a good idea. would you know how crontabs should look
like for a reboot at say 10:00pm? I'll figure out loading programs at boot,
I guess.
I still have to kick users off the system during daytime when they're
inactive for over an hour for obvious security concerns. HR is not
cooperating :-(
Thanks once more.

You should just have to add a line to Cron with 'shutdown -Fr' to reboot
the system at the desired time. Then have another line in Cron that
starts your backup script about 10-15 minutes later.

Kills all users idle more that 45 minutes. Run it in cron.

my=`/usr/bin/who -u|/usr/bin/grep -v nppp|/usr/bin/awk '{ if($6>"0:45") print($
7)}'`
if [ "$my" ]
then
kill -1 $my >/dev/null 2>&1
sleep 10
my=`/usr/bin/who -u|/usr/bin/awk '{ if($6>"0:45") print($7)}'`
if [ "$my" ]
then
kill -9 $my >/dev/null 2>&1
fi
fi

Better VERY late than never? Our newsfeed has been down for quite a
while and I'm just catching up. Saw a number of good suggestions.
As was noted, TMOUT is good, but only for users at a shell prompt.
And a script based on "who -u" can be a problem: This command shows
terminal idle time but it WILL consider a user who is running a cpu
bound job (like a report) with no keyboard activity) to be idle. So
it could log them off in the middle of the report.

We wrote (and sell ;-) a product called LOGMON. This software monitors
the cpu usage for each user, and their child processes. That way we can
be sure the user really is idle. It can then send warnings and/or log
the user off. You can vary the inactivity time by user, time of day,
etc. For details, send a message to logmon@computron.com or visit
www.logmon.com

Thanks!
