SOCKS Server and Library for Java. Support for versions 4 and 5 of SOCKS protocol. Designed to be easily expandable to support different encryption/authentication/authorization methods. Sample server and client are available.
This project intends to make a SOCKS compatible tunnel proxy which communicates to the server part, running on your nameserver, over standard DNS (UDP) protocol. That way you can bypass network firewalls allowing no other IP traffic but DNS.
