[ubuntu] Ubu Server 10 connection problem

Hi all.

The network was running fine yesterday, but today it's not doing anything productive. I don't know what the problem could be.
The network card is detected and shows up with lspci, and eth0 is up, but doesn't appear to be 'running'.

ifconfig shows:

Code:

eth0 Link encap:Etheet HWaddr 00:10:18:2c:13:b7 inet addr:10.4.56.3 Bcast:10.4.56.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:16
route shows:

Code:

Destination Gateway Genmask Flags Metric Ref Use Iface
localnet * 255.255.255.0 U 0 0 0 eth0
default 10.4.56.11 0.0.0.0 UG 100 0 0 eth0
It can only ping itself, and not other networked computers nor inteet sites.
I tried 'sudo dhclient eth0' and after a while, it told me 'No DCHPOFFERS received'. The etheet cable seems fine because the lights are on.

Anyone know what all this could mean?

P.S. Sorry for the odd formatting. And I'll try a live-cd to make sure the card is working properly.
