I need a hint for my usage of debian wheezy 7.8 (desktop Kernel 3.2.0-4 and Gnome) to finally edit one specific file with nano. It is about choosing one DNS in the network manager. Therefore I read to edit the following file
/etc/NetworkManager/system-connections# Wired connections 1
By typing as root # cat Wired connections 1
there is literally an empty terminal. Looking at it, I already changed the rights with chmod -R, just to be sure it is writable, there still is an empty screen in the root terminal when typing
nano Wired connections 1
It ain't empty, thats for sure.
With gedit I can see what I'd like to change, the following line from the file mentioned above
[ipv4] method=auto dns=123.456.78.90; ignore-auto-dns=true may-fail=false
I want to change
But as nano shows me just nothing, cat does the same, I can't figure out how to get it done, without creating much trouble.
Anyone who got a hint how to do this? Thanks in advance. Still looking for clues. And yes, package python-dbus is installed.
Have a little mercy for the missing code-quotes, they did not result in the desired output here, thats why I put them in bold letters. Excuse me.
