making secure limitations for non-root users

[Tyler Littlefield]

Hello,
I've got a quick couple of questions:
First, I'd like to allow users to connect and host a mud on my system.
I would, however like to limit them in disk space (I can figure that one out), in port usage (not sure how to do this one, would like to limit what ports they can open), programs they can run, and also what they can view on the system.
Any ideas?


Thanks,
