I use a VPN tunnel in order to connect to my work LAN.
As long as the tunnel is active it works well, but now and then I'm "thrown off" the tunnel. It happens without any warning, so there is a severe risk of loosing unsaved changes.
I would really like to fix whatever error causes the tunnel breakdown.
The tunnel is started through the NetworkManager.
Any of you have an idea for how to debug this further?
Best regards,
Kenneth
Below is a paste of my /var/log/messages (the "pretty" time 09:45:00 is a coincidence):
