NetworkManager script dispatcher

[Paolo Bolzoni <paolo bolzoni brown gmail com>]

Dear list,
I am using a vpn and I setup a script that
connects automatically when I plug a usb
external ethernet device, the script also
reconnect if the vpn connection falls down.

Now, I have some problems. The script
reconnects also if I manually disconnect
(using nm-applet or nmcli) and it messes
up if I disconnect the cable.

Is there a way to "know more" in the script
what happened? Why the vpn falls down, if
the cable is still connected...

Thanks,
Paolo
