But even without a firewall your Linux computer is remarkably safe compared to a Windows machine. I forget the web address, but sometime ago a security analysis site put a Mandrake computer with default settings on the web without a firewall, and invited all comers to try to crack it. It took over 6 months before anyone managed to find a way in. And before you ask, No you do not need any anti virus software in Linux. Effectively there are no Linux viruses. You are not going to get infected.

RE: [newbie] Logging off a user ?
kill -9 PID is the command you want to wipe out any task running. User ROOT can kill tasks not associated with this, so it woul d have to be a ROOT owned crontab entry. Also you may want to look at the grep piping into cut to get the acual PID's of the the output generated from the grep. Do a man on cut for the specifics. Lastly I wouldn't put cron entry to run every minute. Better yet is to have a shell script that runs the grep|cut as mentioned, sleeps for 1 minute, the loops back to the top. Use Cron to kickstart it for the first time, at 8:00pm or whatever once a day. The script can check to see if the script is already running, and if so, just exists gracefully so that you don't have a bunch of the same script running. Essentially use Cron as watchdog, but the script actually performs the work and goes to sleep and then works again. Cheers!
