You can make nm to not handle interfaces listed in /etc/network/interfaces. Just ensure that /etc/Networkmanager/NetworkManager.conf contains: [main] plugins=ifupdown [ifupdown] managed=false I think this is default config anyway. Additionally there is a "keyfile" plugin which had a "unmanaged-devices" option. See manpage for details. -- gnuPG keyid: 8C2BAF51 fingerprint: 28EE 8438 E688 D992 3661 C753 90B3 BAAA 8C2B AF51
