system-connection for WWAN not working

[van Schelve <public van-schelve de>]

Hello.

I trying to create a system-connection for an internal wwan module under
ubuntu-karmic.

When configuring as a user connection I am able to use it for dial-up
later. Now I changed this connection and set the hook in "available to all
users" with the following results:

- I need to type in my login password again
- a new file is in /etc/NetworkManager/system-connections/:
root c399415:~# ls -l /etc/NetworkManager/system-connections/
-rw------- 1 root root 749 Nov 16 14:53 MyWWAN

- When trying to connect the pppd terminates with signal 15:

Nov 16 14:55:56 c399415 pppd[3491]: Plugin
/usr/lib/pppd/2.4.4/nm-pppd-plugin.so loaded.
Nov 16 14:55:56 c399415 pppd[3491]: pppd 2.4.5 started by root, uid 0
Nov 16 14:55:56 c399415 pppd[3491]: Removed stale lock on ttyUSB2 (pid
3362)
Nov 16 14:55:56 c399415 pppd[3491]: Using interface ppp0
Nov 16 14:55:56 c399415 pppd[3491]: Connect: ppp0 <--> /dev/ttyUSB2
Nov 16 14:55:56 c399415 pppd[3491]: CHAP authentication succeeded
Nov 16 14:55:56 c399415 pppd[3491]: CHAP authentication succeeded
Nov 16 14:56:16 c399415 pppd[3491]: Terminating on signal 15

- When trying to connect again the NM symbol rotates extremly fast in the
gnome-panel but no pppd comes up under the hood.


I also tried to create the connection from scratch with sudo
nm-connection-editor but the effect is the same.

The packages I'm using are the original versions from Karmic:

ii  network-manager                      
0.8~a~git.20091013t193206.679d548-0ubuntu1 network management framework
daemon
ii  network-manager-gnome                
0.8~a~git.20091014t134532.4033e62-0ubuntu1 network management framework
(GNOME frontend


Thank you for your help!
