unexplained disconnect of eth0 or vpn

[equaeghe]

Hi,

Everytime some time (order 30 minutes) after I start up my computer and network connections (eth0 to ADSL-modem, vpn connection using vpnc) (all at boot) the vpn connection goes down. Just restarting vpnc solves everything (afterwards, there is no more disconnection).

Already tried: continuous ping (once every minute or so) to the vpn server. No improvement.

Having to drop to a root terminal to type "/etc/init.d/vpnc restart" is starting to annoy me, so I have two questions:
1) How can I find out what the problem is and solve it? (Anyone encounter something similar?)
2) In the meantime, is there a way to automatically restart the vpnc-daemon when it goes down (e.g., if ping doesn't get a response after some time, trigger restart). Please be very verbose when explaining!

Thanks in advance,

Erik

Exactly the same here. There are lot of discussions in university groups but no one knows the reason of the disconnects.
