In the case of a lost connection this is always the case, yes. That is not very common for me though, as I generally use a wired connection. I'm talking about the user asking NetworkManager to shut down the vpn (through the applet, in my case). I currently have to take the following steps to get work done, and I'm trying to automate it as much as possible: 1. connect to vpn 2. mount network drives with same username and password as the vpn 3. work 4. unmount network drives 5. disconnect vpn It does appear that there is no way to get notified by NetworkManager when I ask it to bring the vpn down (even by writing my own DBUS signal listener, which was easier than I expected it to be) in such a way that there is always enough time for my script to cleanly unmount the drive. This is something that could be fixed by waiting a short while between sending the notification and actually killing pppd. In any case, I have somewhat succeeded in automating the first two steps with the attached script. The way it works does make me rather uncomfortable, especially with nm-ppp-auth-dialog dumping passwords from the keyring to stdout. It also still requires me to run this script manually instead of using the applet. Regards, Ronald.
