The subject is actually not very appropriate....
I should have used "how to find a "jumpstart client" ethernet address?"

The answer was
- Read it on the box"
- STOP-A the machine on poweron, but before boot"

well, thanx... the first answer works when I have the box....which is not
always the case for me unfortunatly.....
and the second works when you actually CAN send a stop-A to the machine... I
sometimes spend
alot of time playing with keyborads, cables and VTs... and that really
sucks....

as for the snoop comand, I found out I need not run it indefinitly... I could
use the -c parameter
to tell it to just find one rarp packet then stop... which is just fine with
me....

Thanx all,
mohamed.
