hmm, i'm using nt at work, so i use putty.  i know there is a way to
specify destination port.  how do i specify source port (like ssh -P)?

also, as long as i use sshd and an ssh client to communicate back and
forth, does it matter which ports they use?  isn't one port as good as
another in this case, since the encryption is handled by the server and
client?  is it less secure because i am using port 23 instead of 22?
hope not.
