proxy chains - redirect connections through proxy servers

 Proxy chains force any tcp connection made by any given tcp client
 to follow through proxy (or proxy chain). It is a kind of proxifier.
 It acts like sockscap / premeo / eborder driver ( intercepts TCP calls )
 .
 This version supports SOCKS4, SOCKS5 and HTTP CONNECT proxy servers.
 Different proxy types can be mixed in the same chain.
 .
