My workaround nowadays is to go to the Network Manager icon and edit the connection to put my desired MAC address as the 'cloned address'. When i start the computer back up, it's once again got a different MAC address and eth* number but i can change it to the current one - which is a tiny bit faster than typing console commands but still not a fix.
The relevant content of /etc/udev/rules.d/70-persistent-net.rules shows: # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:51:81:06:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:c0:1f:39:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:53:52:6a:f2", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:30:42:91:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:37:3c:c9:f2", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:8c:0b:a6:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:4a:73:92:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth6" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:e9:61:8b:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth7" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:70:69:3d:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth8" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:32:ff:77:fa", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth9" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:c7:1c:0c:f5", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth10" # USB device 0x148f:0x2870 (usb) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="80:1f:02:06:1f:11", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan1" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:5f:5f:a4:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth11" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:fc:d3:bc:f2", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth12" # PCI device 0x1969:0x1026 (ATL1E) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:00:fc:4d:b7:f3", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth13" Why does it keep getting a new address, hence a new eth number assigned? Is this a driver fault or a bug in an ubuntu config file? And more importantly, is there a way to fix this? :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/919504 Title: Recurring MAC address problem with ATL1E Driver after suspend/shutdown/restart/ethernet cable removal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/919504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
