James, thank you for the useful tip. The output of macchanger:
# macchanger eth1
Current MAC: 00:15:17:1a:6e:6d (Intel Corporate)
Faked MAC: 00:15:17:1a:6e:6e (Intel Corporate)
# macchanger eth0
Current MAC: 00:15:17:1a:6e:6c (Intel Corporate)
Faked MAC: 00:15:17:1a:6e:6d (Intel Corporate)
How is it possible? I thought NIC has one MAC only.What does mean
'Faked MAC'?
