Thanks Conrad. That doesn't seem to work. netdump -s reports "Failed to 
ARP server" then "failed to locate MAC address". Both systems are in the 
same local network and the system that crashed did have a network 
configured prior to crash. In fact, I was logged in over ssh in one of 
the terminals. I tried through a switch and when the network is 
connected directly. I tried to specify the interface and the client IP.

Is there a way to specify MAC directly?
