tcptunnel is a simple TCP tunnel written in Perl.

Also is a versatile tcp tunnel. The tcptunnel uses:
- tunnelling through a firewall or proxy
- redirecting tcp connections to other ports or machines
- debugging tcp connections in-place
- packet sniffing

The tcptunnel listens on local port < port > and when a connection is made it connects the other end of the tunnel as follows:
a) With no proxy specified, it connects the other end
to < srvport > on < srv >.
b) With a proxy, it connects to < srvport > on < proxy >.
It then directs the proxy to telnet to < srv >, and then it connects the ends of the tunnel.
