Thanks for the detail mail. >Hello Mukund, >Have faced this problem a while back when I was working on an accounting >software which extracts user activity based on squid / sendmail logs.

And every time user logs in, 30 min are reduced from his total allowable time. But thats not the gentleman way out...;-) Regards, Mukund Deshmukh Beta Computronics Pvt. Ltd.
