I have two questions for you. 1. I have experienced a DoS attack by one of my users who has used 100% of the cpu. I do have limits, and the process was killed after consuming 1h of CPU time. is there any way to limit the process to CPU usage? 2. After I create a user, the mail box doesn't seem to work correctly. I try to run elm as a new user that I created and it is exiting with a signal 6 because it cannot read /var/mail/user. This is a printout of ll in that dir after that command has run: -r-------- 1 test mail 5 Mar 10 17:36 test.lock This is a normal users file: -rw------- 1 user users 0 Jan 29 18:29 user the problem seems to automatically fix itself after a while, or after someone sends a message to that mailbox. Is there any way to have this fixed automatically? Also, on another box I have seen that the files have the permission of user/mail. Is this because of security? And how can I impliment it like that if it is for security? Please help. --bhishan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
