Hans,

Make sure you have libpcap-devel installed. I'm not looking at the bridge code at the moment, but you'll obviously want to make sure that you are pointing to your libpcap libraries when you do the compile. 

$ rpm -qa |grep -i libpcap   # determine if packet cap libs are installed

Cheers,

Joe

Johnny, as soon as I've figured out how this works I'll write a manual for
you :-)
But you've got to guide me through the entire painful process first.
I had to shut down my Fedora 9 workstation because of the heat.
The error messages I got while attempting to compile the source were all
related to 'pcap'. Any suggestions?

Hans

PS
Later in the evening when the system is up again I'll post more information.

You don't need "your own" port number. You need a port number. You are
free to pick any that isn't used by something else on your system.

That said, 4744 works just as fine as anything else, including 4711. As
Sampsa pointed out, you can use 4711 as well, if you want to. It only
needs to be unique on your system. What ports I (or anyone else) is
using, does not affect you more than that you have to have that
information in your conf-file.

Your own port number is specified on the command line, as mentioned as well.

Oh, and the reason you haven't seen a manual about the bridge program is
because I've never written one. :-)
Feel free to contribute... ;-)
