Restricting Internet access for Windows users using Ubuntu Server + Webmin

Question

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

Answer 1

This may sound rude, but avoid Webmin. Only if you intend NOT to learn something, you should use Webmin.

So all your requirements can easily be done with Squid

Answer 2

I don't know much about webmin, but I am pretty sure that squid can do what you want.
