This is a TCP port redirector for UNIX. It can be run under inetd or as
standalone (in which case it handles multiple connections). It is 8 bit
clean, not limited to line mode, is small and lightweight. If you want
access control, run it under xinetd, or inetd with TCP wrappers.
Redir listens for TCP connections on a given port, and, when it receives
a connection, then connects to a given destination address:port, and
pass data between them. It finds most of its applications in traversing
firewalls, but, of course, there are other uses.
