[ubuntu] Ubu Server 10 coection problem

Hi all.

The network was ruing 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 'ruing'.

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.
