Hope this helps... - Jy@ I've seen people use .logout scripts and also run a cron job once a day (during non-peak hours) to kill all processes associated with a username that isn't connected to the machine remotely (telnet/ssh) or sitting at the console. .logout scripts seem to work 99.9% of the time, since most users (including myself) are inept. The Sun machines at school don't let you remove the .logout scripts or in case of the Linux boxen they just re-add them on deletion somehow. I haven't got the foggiest idea what they did to do this. -Brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
