Hi

Wanted find out from the fundies here if it's possible to track internet usage on a local network at the school I work at. We suspect one of the teachers or learners are abusing the uncapped internet we have, causing our ISP to start throttling us within a couple of days within our monthly usage as we are apparently breaking the fair usage policy of our ISP.

Is there no way to track who is using the internet, and even better, what sites they are using?
 
Have you got any sort of server setup? or is your LAN running through switches etc? How many client pc's?
 
You should have a proxy server setup at the school where all internet traffic goes through, it will be easy to manage and keep track of usage on any PC on the local network
 
Depends on your network setup.

Personally would use a proxy server, firewall or similar to track and control.
 
Yup.
Authenticating proxy, with nothing allowed out to the internet except the proxy itself.
 
Think the last one I used was smoothwall and it was quite good for the price (free) :D

Smoothwall.
URL Filter (blocks porn and other naughty sites)
SARG (Squid Analysis Report Generator) gives you a break down of sites visited, how long was the visit, and popular sites.
 
I am in the same situation. I use Untangle with the Captive Portal app.

Works well and you can integrate it with your ADDS as well (and works with nComputing terminals to boot)
 
Wow, thanks for the great response from everyone.

Our system works as follows:

ADSL -> 4-Port Wireless Router with about 8 laptops connected -> 16-Port Switch with about 12 Desktops connected

We don't have our own server.

Surely you guys have a PC lying around you can use as a server, just needs two LAN cards. You will also require another AP or ADSL Modem

ADSL -> 4-Port Wireless Router -> Firewall/Proxy Server -> 16-Port Switch with about 12 Desktops connected + AP for laptops

or

ADSL -> ADSL Modem -> Firewall/Proxy Server handling PPPoE as well -> 16-Port Switch with about 12 Desktops connected + 4-Port Wireless Router for laptops
