This is what happens in my case: 1) Change MAC address of an existing connection named Auto eth0 2) Network Manager will create a new connection named Auto Ethernet 3) Network Manager will automatically connect via Auto Ethernet
No matter what I do, Network Manager won't allow me to connect via Auto eth0 Here's my workaround 1) sudo update-rc.d -f NetworkManager remove or sudo update-rc.d -f network-manager remove (on Lucid) 2) uncheck Network Manager from System > Preferences > Startup Applications 3) edit /etc/resolv.conf nameserver 8.8.8.8 nameserver 8.8.4.4 4) edit /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.15.220 netmask 255.255.252.0 gateway 192.168.13.1 # this is the non-default mac address hwaddress ether 00:11:95:60:A4:A4 5) sudo /etc/init.d/NetworkManager stop 6) kill network manager applet 7) restart networking: sudo /etc/init.d/networking restart sudo service networking restart 8) or reboot as an alternative to steps 5-7 -- Network manager doesn't change the MAC address of the ethernet card https://bugs.launchpad.net/bugs/570632 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
