Redsocks is a daemon running on the local system, that will transparently
tunnel any TCP connection via a remote SOCKS4, SOCKS5 or HTTP proxy server. It
uses the system firewall's redirection facility to intercept TCP connections,
thus the redirection is system-wide, with fine-grained control, and does
not depend on LD_PRELOAD libraries.
