I'm hacking on the CMU version of Netwatch, and wondered if anyone could help me out. I'm looking for a good basic primer on ethernet protocols, including TCP/IP. I'm also looking to find a list of the "vendor prefixes" for various card manufacturers, ie - the three high order bytes of the ethernet address which identify the vendor. I want to modify the program to recognize more vendors. Finally, I am looking for information about multicasts - does anyone have a good explanation of how I can distinguish them? Oops, almost forgot - also, does anyone know what "type" 3COM and U/B and Novell use for their ethernet packets. My version of netwatch now recognizes Banyan packets, many other DECnet packets, plus the original IP packet types. I'm also modifying the filters to be more flexible (AND, OR, and NOT on address or type, or specific bytes in the packet, or particular sizes, etc), and to allow an option to save a session. Anyone have anything else they'd like to see while I'm at it? Thanks a bunch. -- =============================================================================== Scott A.

_An Introduction to TCP/IP_ by John Davidson is a new (1988) book published by Springer-Verlag. I found it very informative, although I was a little disappointed that it only discussed TCP/IP over Ethernet and not over token ring or anything else. However, since you're only interested in Ethernet, this shouldn't matter. The ISBN is 0-387-96651-X. The bad news: for being less than 100 pages, it's UNGODLY expensive at $25.

I have done a good deal of similar hacking to CMU PCIP and netwatch
in particular. I plan to post the whole thing for anonymous ftp
in the next few days. At that time I will say more about what I have
done to netwatch, which is one of my favorite toys.
