Setting up a gateway server with bandwidth monitoring?

critical · 03-26-2006, 11:12 PM

Howdy,

I'm setting up a ubuntu machine as an internet gateway,

I've set one up previous using iptables & firestarter which was fairly straight forward,

A couple of things I would like to do

- Monitor monthly bandwidth usage based on lan ip
- Restrict bandwidth on certain ips? maybe even restrict bandwidth during certain times?

I don't nessessarily need a step by step guide, just a point in the right direction and I should be able to figure out the rest

(I've looked into solutions which turn the machine into a dedicated gateway however that doesn't really work for me)

(Also the reason why this isn't in the ubuntu thread is because I'm considering doing this in either debian or freebsd)

Cheers!

well you could look into a program called squish, i've writtern a how-to about it on my website using pam auth, i think it can be used with IP addresses instead of usernames

Looks like Squish is used for a proxy server however unfortunately my gateway users need all types of internet access

what do you mean all types? any type of interent access is not offered by a proxy server?

for some reason your squish howto does'nt work on my setup (Fedora Core 3 and squid with proxy_auth (pam_auth) and dansguardian). I thought of alternate way since i only want per user bandwidth limiting. I modified the squish perl script to echo the offending users to a file in /etc/security/squish and then add this line in /etc/pam.d/squid:

Quote:

auth required pam_listfile.so item=user sense=deny file=/etc/security/squished onerr=succeed

hope that makes sense
