How to complely automate jumpstart?
2007-12-25 10:14:00
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.
