I am new at Linux, but have installed Ubuntu 12.04. I have set up 1 x Administrator account and 3 x User accounts. Is there a way that prevents downloads from the internet for the user accounts.
...additionally you could do anything from using a transparent proxy to firewall rules that match user UIDs to removing any network connecting applications altogether (and yes, BASH understands TCP too ;-p), but what exactly would you like to accomplish?.. And would the machine still allow CD, DVD, USB, Bluetooth, eSATA, etc, etc?

What I am trying to do is save bandwidth, and prevent music and video downloads.
Policy routing does do just that: route traffic. On it's own it will accomplish nothing: it's where you route traffic to and how that'll be processed (say a caching or filtering proxy or a traffic shaping queue) that matters.

Saving bandwidth means mostly caching (repeated requests for static content), for dividing bandwidth between clients (equally or not so equal) there's QoS and bandwidth shaping (search for LARTs "wondershaper" for example) and for "stopping downloads" or filtering out unwanted content) you use a filtering proxy (Dans Guardian and to a lesser extent Privoxy).

Okay, thank you. We are restricted to 2GB a month on the internet
