Setting disk ratios and monitoring bandwith usage.

Hi there,
I have a small project for which I need to create accounts on my
computer and for each accounts, I'll need to set a disk space the
account can use (should give an error like "Disk quota exceeded" if
the user go beyond that limit) and I would like to monitor the usage
of the internet per users.
For the bandwith, I was thinking on setting a simple firewall rule
that would log every packets for a specific IP (each account should
have a diff IP) and there should be a program, reading the firewall
logs, every day and summarise the usage on a daily basis.

Then for the disk, who do we setup quotas for the space?

Also, is it possible to set the /home/ directory to be unreadable?
That the user could only read what is inside /home/user/ for
example...

Thanks a lot!

Ok, I check this out and actually, this doesn't seem like a good
solution. After thinking a bit, I figured I might have to drop some
packets to avoid DOS and such, but I'd still need to know how much
trafic goes to a specific IP on my host. I've heard about QoS, but
I'm wondering if that's windows oriented, I'm using Redhat 9 or so...

That's alright, I found the quota Howto! So I'll be able to play with
it a little.

And for this well, I guess what I'm looking for is to make some sort
of Virtual private networking. But I'll do some tests...

Thanks,

If each user is going to have a separate IP, download a program like
mrtg and get it to track the bandwidth statistics for you.

Good, if they do not have different IP addresses, what could be done?

Thankx,
