We have 3com Ethernet boards in one of our Apollos. Can any kind
soul tell me, how I can get the Ethernet No. of one of these boards?

try 'arp <hostname>' where <hostname> is the name of the host you want
to know the ethernet address of.
See the man page for arp

3COM supplies diagnostics diskettes for its IBM PC XT/AT -slot
products that are in executable, 8086 code -- Among the things
this code (3C503.EXE) does is the reporting of the five hex
bytes of the ethernet address. It may seem like brute force, but
if you don't get help from 3COM (have you contacted them directly?)
you could slip the card into an IBM -- I have the software and
could e-mail it to you.

On the back of the board, there is a label in English that specifies the "NETWORK ADDRESS". This number has two parts; an assigned prefix that identifies the interface as being manufactured by 3com, and a unique part that identifies the specific board. This second part of the address is also located on the small prom chip that encodes the address. On a 3c505 card the first part of the address is 02.60.8C and the prom is at U17. A 3c503 card will have a similar set of lables. If the system is up and running you can find out the Ethernet address by using the arp command available under UNIX.

It may be a part of the tcp 3.x BSD stuff but I can't check it out. If it is included it should be in /etc (bsd4.2/etc). I know the BSD TCP 3.x release included ping and I thought arp as well but after a year the memory fades. (:-) But, I did remember another way to find out the ethernet address. When you start tcp_server give it a -d option. This will tell it to run in debug mode and the server will print the ethernet address of it's interface as a part of the startup in the window. I also belive the ether_diag program will print it, but not everyone has the ether_diag on their systems. (something about which release tape it was on) Anyway, I hope this is more helpful ( My apollo is still under water from the last time the basement flooded, so all I had to check with last time was my Sun) -- Steven E.

I seem to remember (it was some 2 years ago when I looked at it), that Apollo's PC/AT Eth boards are NOT the ones you can buy in a shop, due to a different ROM Apollo ships with them. Also, apparently Apollo overwrites the standard (3Com) eth address with Apollo's own address, that is 8:0:1e:??:??:??, where the last ??:??:?? stands for the hexadecimal nodeid of the machine. So the same eth board will have different h/w addresses depending on which node it is plugged in. I was checking that when first installed domain on eth and we wanted to know how much traffic was generated in, otherwise idle, conditions. Obviously it took a couple of hours to realize that the board address was overwritten :-) Achille Petrilli Cray and PWS operation
