and do a search on pcap or sniffer. There's 3 or 4 really good ones. One
is GTK based, one is QT based, and the remainder are curses or plain-text
based.

They might have it now. They're slowly working their way through the
entire linux app list and adding and testing and rating them as they go.

1. How to rewrite only the port on incoming/outgoing packets
I've got a client program that talks to one or more server programs. The
restriction being that each server program must run on the same tcp port or the
client won't communicate properly. When run from different machines, this works
fine. I'd like to run 2 servers from the same machine. One of the
possible ways I've figured to do this is: the servers are run from Netra T1
machines which have 2 ethernet interfaces. Is it possible to get some kind
of port redirection software for unix that can sit on the Netra and listen to
one of the interfaces and rewrite port calls to it? This way one of the servers
could run on 30000, and the other on 30001. Any traffic directed for one
interface on 30000 would remain the same and connect to the server on 30000.
Any traffic directed for the other interface on 30000 would get rewritten with
the destination port 30001 and passed in to the server at 30001. The same
would have to happen for outgoing packets. Is this possible or can you
think of another way to accomplish this?

13. PPP load balancing works for incoming but not outgoing???
