I want to restrict the Internet usage for a couple of Windows users on a network. The Server is a Ubuntu 10.04 Server running Webmin - all Windows users are setup as users on the Ubuntu server to authenticate to the Samba shares.
What I'd like to do is setup a proxy server on the Server that all users are routed through, and a few specific users would be restricted to access only a whitelist of websites, perhaps at specific times of the day.
What's a good way to achieve this using Ubuntu and Webmin?
Cheers,
Matt
