How can i monitor(analyze) all data packages between these

I have a question.Can you help me?
Question is: Data packages are sent or received between two computers. the
computers run qnx4.25 OS. their net protocol is ethernet 8802.3. How can i
monitor(analyze) all data packages between these computers?
Thank you!

Check out tcpdump. I believe it’s on the 3rd party disk. I have used it
quite effectivly. NOTE: the card/driver must be in promiscuous mode for
this to work.

In fact I capture my packets with tcpdump and write them to a file. Then I
display them with my own filtering/formatting program. This way you can
interpret any propritary application data packages that you have.
