Cloned mac line take no effect according to ifconfig output. How to fix it? Is this a bug?
I’m not sure if this will help in your situation, but it’s worth a shot.
This is an excerpt from an askubuntu tagged hot answers post:
[quote]1: dhclient -r to release the dhcp lease
2: remove all the dhcp lease files from /var/lib/dhcp/
3: edit /etc/network/interfaces to change the hwaddress line to something random, restart network and repeat several times, then finally restore the cloned mac address and restart network.[/quote]

Of course not. This is not about how to change it actually. But how to make it works through NM. Because I remeber it had work not so long ago. Weird that this have no effect now.
