Duplicated MAC addresses

Had a fairly interesting one today, a client complained about the speed of their proxy server running squid.

This machine has two network interfaces and upon investigation it transpired by looking at their router logs that both had identical MAC addresses leading to all sorts of mayhem.

Disabling the second network interface (which was only in the machine as a 'hot spare' resolved the issue.
