why? ...
I think it 's easier to edit the standard files than having to deal with yet another MadManInTheMiddle Madness :)
I am kidding NetworkManager is cool ... but I cannot stand it.
Check NetworkManager Status
# nmcli nm RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running connected enabled enabled enabled disabled # nmcli dev DEVICE TYPE STATE eth0 802-3-ethernet connected
Stop Network Manager
# /etc/init.d/network-manager stop [ ok ] Stopping network connection manager: NetworkManager.
Remove Network Manager init script links
# update-rc.d network-manager remove update-rc.d: using dependency based boot sequencing
From
# man NetworkManager.conf
[ifupdown]
This section contains ifupdown-specific options and thus only has effect when using ifupdown plugin.
managed=false | true
Controls whether interfaces listed in the 'interfaces' file are managed by NetworkManager. If set to true, then interfaces listed in /etc/network/interfaces are managed by NetworkManager. If set to false, then any interface listed in /etc/network/interfaces will be ignored by NetworkManager.
so something like the following should work
# cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile [ifupdown] managed=false
Edit /etc/network/interfaces eg:
# cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback auto eth0 allow-hotplug eth0 iface eth0 inet static address 10.2.24.50 netmask 255.255.255.128 gateway 10.2.24.125
Set nameserver
# echo "nameserver 10.2.24.4" > /etc/resolv.conf
Restart networking
# /etc/init.d/networking restart [warn] Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces ... (warning). [ ok ] Reconfiguring network interfaces...done.
and check with
# ifconfig
Restart the system to check
# shutdown -r now
OK, it works.
Disable the NetworkManager in Debian
