Make my program listen on a port.

[Matthew Carpenter]

Another couple options for this, which is pertinent to the list:

inetd:  listen on another port and redirect from one to the other
iptables: iptables -t nat -I PREROUTING -p tcp --dport <origport> -j REDIRECT 
--to-ports <desiredport>
	You can also try using DNAT if this doesn't produce the desired results.

There are likely other port redirectors which would serve this purpose...  for 
testing, netcat is always fun to use for this.  netcat redirector:

# mknod backpipe p
# while true; do
> nc -l -p <desiredport>  0<backpipe | nc localhost <origport> >backpipe
> done

:)
Have a great day!

ps.  <OT> My team, "lastplace", is competing in DefCon 14 Capture the Flag, 
August 4-6.  If you guys will be there, drop me a note!  love to share a 
couple minutes over a cup of favorite beverage... what few moments I'll be 
able to spare.
