Tools available for..

[Jeff Davis <jdavis@wasabimg.com>]

I am trying to set up a server, and I would like to know about some of
the tools I should be using for the following tasks:

Bandwidth monitoring/restriction on a per-user basis

Traffic (total data transfered per time unit) monitoring/restriction on
a per-user basis

CPU & RAM would also be nice, but I assume linux won't let a user
totally take over the machine's resources with default options.

port forwarding (I tried this one already, but had a tough time, perhaps
just direction to some good tools or docs).

I also plan to set up disk quotas (as you may have guessed), but from
the documnetation it looks straightforward.

I would appreciate any advice. I am refering to Debian 2.2.

Thanks,
Jeff Davis
