It's probably hard-wired the MAC into the udev rules. Move "/etc/udev/rules/70-persistent-net.rules" out and reboot (there's probably a way of regenerating it with udevadm but I don't know it). It'll be regenerated with your original MACs. You can diff the old and new to be sure. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
