Linux - Tutorial how to undo pppoeconf settings

To undo the pppoeconf settings isn't very easy. If you use the pppoeconf settings you can connect to the Internet without connecting via network manager. So if there is a case that you want to undo this settings, without reinstalling the whole operating system, I have a little tutorial.

1) open console

2) get root:
sudo -s

3) edit nm-system-settings.conf
cd /etc/NetworkManager
ls -la
gedit ./nm-system-settings.conf

You have to write managed=true under [ifupdown]

4) edit interfaces
cd /etc/network
ls -la
gedit interfaces
This file must look like this:
auto lo
iface lo inet loopback

auto eth0
iface eth0 dhcp

5) Restart your computer

6) Finished.

PS: If there are some questions, make a comment.  


  1. I'm going to try it right now - thanks for your tutorial.

  2. thank much, worked great. only thing is now under my wired connections i have an entry for ifupdown(eth0), which i cannot delete.

    i assume it has something to do w/ my nm-system-settings.conf file, which looks like:




    can you tell me what to modify in there? does not seem to be causing any probs, but just want to know.
