Look, only the loopback interface 'lo'!!!

Look, eth0 should be coming up, but it sure wasn't there in the ifconfig
output. When the box is on, check where the network cable plugs in and
see if you have blinky lights. What lights are there depends on the NIC,
but often you have a solid light for a link, and an intermittently
flashing activity light.

Also, try 'ifconfig eth0' and see if you get something, or if it
complains that there is no eth0. If it says Invalid Interface, or Are
You On Crack?, then it's likely your network card died. If it comes back
with words like 'DOWN' or 'NO LINK' then it sees the NIC but maybe
something's wrong with the cable or some such.
