Depends on what your users are supposed to be doing and what services you are supposed to be providing. In many cases, the answer is to limit everything to very small values and to gradually extend these for those users who complain and who show that they need more. In other circumstances, you give everybody the world and jump heavily on people who abuse the system. There's no best answer to this. -- Greg Black To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
