Linux - Anonymous proxy server using Anon Proxy for your linux box

Anon proxy is a free open source proxy server, all configuration are done using web based interface. It's come with built in Documentation for installing and using, really nice software for a new Linux user.

Anonymous proxy server. Supports http, https, socks. Can be used as a normal proxy or as a p2p anonymous proxy. Web based drag and drop access configuration. Works with windows, linux. IE, firefox, etc.

But only TCP connects are supported so far. Seems to be enough to run most Instant Messaging programs. User authentication is not supported in socks. You can disable access to socks by adding a "block" rule with "url" "is" "socks://".
