Older versions of WinGate used to run a listener service on port 23
that would take a hostname and a port as input and connect to that.
Real easy to abuse, and also to DoS itself - let it connect to
localhost:23 a bunch of times and eventually Windows would run out
of clean winsocks, thus solving the problem for a little while.
