James, thank you for the useful tip. The output of macchanger: |
33 |
|
34 |
# macchanger eth1 |
35 |
Current MAC: 00:15:17:1a:6e:6d (Intel Corporate) |
36 |
Faked MAC: 00:15:17:1a:6e:6e (Intel Corporate) |
37 |
|
38 |
|
39 |
# macchanger eth0 |
40 |
Current MAC: 00:15:17:1a:6e:6c (Intel Corporate) |
41 |
Faked MAC: 00:15:17:1a:6e:6d (Intel Corporate) |

45 |
'Faked MAC'? |
