Ethernet not working

I am using Beagleboard xm.
I followed the instructions on this site: http://elinux.org/BeagleBoardUbuntu#Demo_Image
to install Maverik on the board.
The board boots up, but I am not able to configure my network (in
order to install the GUI)

I use:
sudo ifconfig -a and sudo dhclient usb1

by running ifconfig, i see lo, usb0 and usb1.

by using dhclient usb1, i get:
No DHCPOFFERS received.
No working leases in persistent database -sleeping.

Please help me!!

Now that's a first..

I'd almost want to blame your dhcp server... Any errors seen thru
dmesg? "dmesg | pastebinit"

Regards,

dmesg | pastebinit gives:

IOError: [Errno socket error] [Errno -3] Temporary failure in name
resolution

Yeah i realized after i sent that message, it would probably be
impossible as pastebinit requires a network connection... I kinda
figured you'd had figured that out and just copied dmesg to another
computer and upload from there..

so do:

sudo ifconfig -a
sudo dhclient usb1 (let it fail)

dmesg > log.txt

copy log.txt from sd card to computer, upload to pastebin.com

This looks like a router problem.. Are you by chance on a campus the
limits internet connections via MAC address's?

I see nothing else in the log that would point to anything.. It works
here on my xM C..
