Question #51238 on Ubuntu Eee changed:

    Status: Open => Answered

Jonathon Hodges proposed the following answer:
Hi Trewornan,
That's interesting.  Ok, well I found this for you:

Open a terminal and type:
ifconfig

That'll give you a report of the current configuration of your network
devices.  Perhaps take a note of your original MAC address from there.
I assume you're trying to reconfigure your wired connection rather than
wifi card.  If so, then type the following:

sudo ifconfig eth0 down
[This will bring down (stop) your network card so you can edit its config.]

ifconfig eth0 hw ether xx :xx :xx :xx :xx :xx
[This will change your mac address to the one that the college has given you, change the xx: for the address they gave you]

sudo ifconfig eth0 up
[Brings your ethernet card back up (restarts it)]

The advice came originally from here:

I can't tell if the change is persistent, I'd be interested to find out.  I think the macchange app in the other method mentioned in the other launchpad article is for getting a fresh new mac address each time you login.  That wouldn't help you if it is.

Another way around your problem would be to use a hardware router (any
wifi router should do) and change the mac address in the router
configuration to the one college gave you.  You might find that simpler
because it's a graphical user interface, but then where's the fun in
that?  Always satisfying to have a bit of a go in the terminal...

Let me know how you get on.

Jon
