So it still can stop the openvpn? Please attach your NetworkManager's log when it was failed. When i instruct knetworkmanager to disconnect from vpn, the tap device and it's routes are removed instantly. However, the error messages persist for several minutes and the half-dead openvpn process hangs around.

kill the NetworkManager then run 'NetworkManager --no-daemon' in terminal with root permission. Then try again.

Tried it, same behavior. (Btw knetworkmanager crashes when NetworkManager --no-daemon is started. Had to start knetworkmanager again) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
