*sigh* I must be going blind. I could have sworn I saw the same
Ethernet address.
Yes, it's a different system. And looking for that explained the
problem:
1. I reboot echunga, which should have a dhcp server, but it didn't
start.
2. My RS/6000 tries to connect to the dhcp server to get an IP
address, but it can't.
Sorry for the confusion.
