Jumpstart: RPC Authentication error
2007-12-24 19:13:00
I have a jumstart server that was connected to a test network and it was
working fine. I have now connected it to the rest of the lan and am
getting problems at the start of the jumpstart. If I connect the two
machines in a private network (crossover cable) it works fine. This leads
me to think that another machine on the network is cuasing problems.
Examining the output on the console (see below) and debug info from rarpd
and bootparamd show that the initial rarp requests go ok. The tftp for the
inetboot image is also successful. The path to the boot image is located.
It fails somewhere in the load of the kernel from the server.
Snooping the network shows that at the time of failure a rarp request from
an unknown IP (202.254.186.221) using the MAC address of the client occurs
(see snoop output below). The address 202.254.186.221 is not an address on
our local network. I have seen a similar thing summary about an SGI
machine interrupting the RPC calls and causing hassles but this isn't so
obvious as the IP is unknown and the only time this IP appears is on 1 line
in the snoop. Where did this IP come from!! It looks as though my machine
has been assigned a new IP somehow as there is not a duplicate MAC addres
problem (I've tried it on two other clients)
This is the output from the client console:

I've searched the archives and sunsolve but can't find any similar problems
let alone solutions!
Thanks,
