How do I un-clone the MAC address on my NIC? This is driving me NUTS!
Using network manager I cloned a mac address (to try and sort out some network issues). I've since removed the entry in 'Cloned MAC address' and am left with two Wired connections:
Auto Ethernet, which still contains the cloned MAC
Auto eth0, which contains the device MAC
eth0 is not listed as an option to connect in nm-applet.
deleting 'Auto Ethernet' does not persist (restarting networking readds it).
ifconfig lists eth1 with the cloned MAC address.
I tried stopping network-manager ('service network-manager stop').
ifconfig -a still lists eth1 with the cloned MAC.
restarting networking ('/etc/init.d/networking restart') was no help (eth1 exists, no eth0).
Removing the module (r8169) then reinserting it, bring back eth1 (no eth0)
70-persistent-net.rules contains a line that remaps eth0 to eth1 and sets up the cloned address:
# PCI device 0x10ec:/sys/devices/pci0000:00/0000:00:1e.0/0000:07:01.0 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:00:00:00:00", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
If I remove the module, delete the line, and then re-add the module, udev re-adds the line.
How do I un-clone the MAC address and get back to just using the one from the device (and preferably get back eth0)?
Not
