Open Source Free Proxy with content/site blocking??

Hey all,

Does anyone know of a free Linux based proxy server that has content blocking available so I can ban certain content/categories or use a whitelist and blacklist of sites sort of thing?

Its a small project I am working on and don't want to pay for any software or buy a router with it built in but I know there must be something out there capable of this?

Cheers for any help guys

 

Can you not pipe it through http://www.opendns.com/ and filter bits out, I'm pretty sure we did that for an client at my previous IT Support job. Was for a kids home to stop them getting on porn and vpns to get around the blocks to get to porn.

Little devils. lol

 

Thanks mate, I have heard of it but thought you had to pay to use it, will go and have a butchers at it now

 

I havent used it myself, but you could look into squid.

Seems to do what you want.

 

Try http://www.smoothwall.org if you have a old crappy PC you can run it on.
