I'm assuming you just want to forward ports on the same box, but if not,
these commands can be easily tweaked to forward information to other
hosts too.
I tried this first:
nc -l -p Y | nc localhost X
It forwards requests, but...
1. You don't get the response back.
2. netcat closes down after the first client disconnects (it seems)
Maybe try ssh tunneling instead? It's not that hard:
ssh -L X:localhost:Y localhost
Of course, you have to have sshd running on your box for this to work.
Also, add a -g if you want other hosts to be able to connect to your
machine, like this:
ssh -g -L X:localhost:Y localhost
Now you can connect from any outside machine (assuming you don't have a
firewall preventing it) to your machine on port X, and it will go to
port Y instead.
Good luck,
Phillip
