RESOLVED: jumpstart client: bootparam authentication error

Date: Thu Dec 10 1998 - 21:49:01 CST

Many thanks to those that replied with helpful suggestions.

The problem turned out to be, believe it or not, an "NT" server configured
to do remote backups (nobody picked that as a likely cause - but then I
didn't mention we had NT boxen on the network ;-). It appears that the NT
box responds aggressively to RPC calls arising from machines it doesn't know
about, rather than just ignoring them. A colleague eventually caught it by
setting up a jumpstart client and another Solaris machine on the same hub,
using the "other" machine to snoop all ethernet activity. This very quickly
revealed the "Authorization error" being sent from the NT server. Our
"production" network is switched, so we didn't see these responses directed
toward the jumpstart client in previous uses of snoop ( e.g. on our
jumpstart server, all we could see were the broadcast requests, and the
responses from the jumpstart server).

Well there you go. A lesson learnt, and a week mostly lost, but that goes
down to "experience". Thanks again for the positive responses. Although not
useful in this instance,it was pleasing to see so many people taking the
time to respond.

Cheers, Jeff
