ProxyChain - Version 1 Fully-customizable system that allows you to connect to the Internet through multiple chains of proxy servers, thereby concealing your actual IP address. ProxyChain supports both HTTP and SOCKS4 protocols which makes it efficient enough to be used for web browsing, e-mail sending, FTP (file transfer protocol), and even chatting. When installed on a server, ProxyChain can act as a stand-alone HTTP or SOCKS4 proxy server.
