I have installed crunchbang statler which is based on debian squeeze.
By default there is network-manager-gnome 0.8.1 (/usr/bin/nm-applet I believe) running with an icon near the clock/tray area.
I can add, edit and delete new connections there, but I cannot delete or change the existing one. There is a popup telling me I have insufficient privileges.
Coming from debian servers and little experience with linux desktops and gnome, I have only heard of the default unix permission system.
But I am not sure if this is the permission system in effect here?
What would be the steps to have full control over the existing connections (that were added by the installer?) using the network-manager-gnome "applet"?
I am in the group "netdev" already.
EDIT: I tried the following:
killall nm-applet sudo nm-applet&
Now I could change and also save the settings, but I have now multiple connections and cannot remove the old ones. On startup the old one gets active.
