Yes, there are three: two with sequential MAC addresses (which coincidentally 
show
up as eth0 and eth1) and one with an out-of-sequence MAC addr (eth2 and the
AMT port).

Sorry for the confusion.

The only reason that the AMT landed on the same IP addr as the machine
is that eth1 (the "normal" port) and eth2 (the AMT port) both have the
same IP address. You should be able to fix this in your DHCP server
settings. (I did this for the huxelrebe1 AMT port to put it on a
different address than the normal linux port.)

Actually, this is because the ethernet cable is plugged into port 1 instead of
port 0 (not that they're labelled - in fact, *because* they aren't labelled).

I did this from newcastle. You might try that as a sanity check.
(On second notice, I'm assuming this was because of a typo in the password
I sent you.)
