Remove ifupdown(eth0) connection

  • 772

While I was installing Ubuntu 14.04 I had some issues with graphic card drivers so I needed to install drivers from root, I created adsl connection using pppoeconf. Now when I boot up my PC I have two connections, my regular connection which I use and ifupdown(eth0) which was created using pppoeconf.

How can I delete eth0 connection so it doesn't bothers me anymore?

    Open your file manager and go to /etc/network/. Once there, you have to edit the file interfaces like this:

      sudo gedit /etc/network/interfaces

    or 

      gksu mousepad /etc/network/interfaces

    and delete all entries in there except for auto lo / iface lo inet loopback.

    The following lines

       auto lo
   iface lo inet loopback

    have to be the only entries present in /etc/network/interfaces.

    Next you should edit a second file located in /etc/NetworkManager/NetworkManager.conf. Use this code in a terminal window:

       sudo gedit /etc/NetworkManager/NetworkManager.conf

    or 

       gksu mousepad /etc/NetworkManager/NetworkManager.conf

    Look for this entry [ifupdown] and edit the entry to look like this:

       [ifupdown]
   managed=false

    Reboot and reconfigure if necessary your network using the network applet from system tray.

  2. Open terminal and enable super user mode.

    nano /etc/NetworkManager/NetworkManager.conf

    The contents of the file will be like this:

    [main]
plugins=ifupdown,keyfile,ofono
dns=dnsmasq  
[ifupdown]  
managed=true

    Please change the plugins section to:

    plugins=keyfile,ofono

    Restart the network manager:

    service network-manager restart

    It worked for me, I hope it will work or you too.
