(Paul, I'm resending this so it goes to the list.)
The interface is certainly up, because when I'm doing the traceroute
that gets the ENETDOWN, I'm SSH'ed into the box through eth0. And
other processes on the machines are running just fine.
And no, there are no messages in /var/log/* about eth0 that I've ever
seen. Everything works just fine except:
1. My desktop can't ping the box.
2. The box can't traceroute (but CAN ping!) my desktop.
