Bug Description

Binary package hint: network-manager-pptp

My employer's windows vpn server, from time to time, times out my connection after a period of being idle. When that happens pppd disconnects but network-manager nor nm-applet reflect this change. As far as they are concerned the connection is still alive. I am using Ubuntu 6.10.

The following is all that I find in my /var/log/messages file when this happens:

Dec 21 05:37:49 bordet pppd[26785]: Modem hangup
Dec 21 05:37:49 bordet pppd[26785]: Connect time 702.1 minutes.

Dec 21 05:37:49 bordet pppd[26785]: Connection terminated.
Dec 21 05:37:49 bordet pppd[26785]: Exit.

the following is from /var/log/debug

this from /var/log/daemon.log

I hope that my log excerpts are helpful. Either way it would be way cool and reliable feeling if the nm-applet reflected the fact that my vpn connection has given up the ghost.

Thanks,
David

I also see the same behavior. I have a VPN tunnel to my office from my home. My DSL connection to the Internet resets about once a day, and pppd sometimes drops its connection. NetworkManager never seems to find out about it (and knetworkmanager doesn't change its icons).

I would like to know what actually causes this. Is it that the network connection between here and the VPN server is bad? Because, strangely, I have this problem when at home, and I don't have it when I'm lurking at the university library (which provides official campus wifi).

Is there any settings that can be tweaked to prevent this?

This plugin must check connection status! I did it manually by checking /dev/ppp0 device presence. Why it can't be done by plugin itself?
