Thanks for the reply, I have pasted my complete routing table below.

Here is my complete route table:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
18.104.22.168 * 255.255.255.192 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default 22.214.171.124 0.0.0.0 UG 0 0 0 eth0
The big difference between mine and yours is that the 169.254.0.0 route
is showing up on eth0 - which is the only port connected. I can get into
the box, but the box can not get out to anyplace. I could be looking in
the wrong place for the solution, I figured that this looks wrong to
have this apparent self-assigned IP on my only active ethernet port.

This is my only active port. If I shut it down, the machine goes away.
