NetworkManager uses PolicyKit to protect various operations like this.
What you want to do is to ensure that the user cannot obtain these
permissions:
org.freedesktop.NetworkManager.enable-disable-wifi
org.freedesktop.NetworkManager.enable-disable-wwan
which you'd do by writing some PolicyKit rules to deny that user these
two permissons. Rules are just files that get dropped
into /etc/polkit-1/rules.d and look like this:
polkit.addRule(function(action, subject) {
if (action.id == "org.freedesktop.NetworkManager.enable-disable-wifi" ||
action.id == "org.freedesktop.NetworkManager.enable-disable-wwan") {
if (subject.isInGroup("wheel")) {
return polkit.Result.YES;
} else {
return polkit.Result.NO;
}
}
});
(or something along those lines) which will deny this permission
completely to any user who is not in the Unix 'wheel' group. There
should be a good bit of info out there on writing policykit rules.
Hope this helps,
Dan
