vpn connection disconnecting when idle

[Emil]

Here's my situation.



I have a database app that connects to a remote database.

They have a secure network so the users need to connect using a VPN
connection



When the PDA is idle for a long period of time the VPN connection is dropped
and the exe produces an error when accessed.



How can I disable the VPN from disconnecting? Is there a way I can "trick"
the PDA from going to an idle status? I tried to call a dummy stored
procedure every five seconds so it thought there was activity but that did
not work. it seems that the idea status is related to hardware, when a key
is struck.



Is there a way I can make my app automatically dial a VPN connection if it
knows that a connection is not active?



any clues?

If the problem is related to power-down, try Alex Feinman's
http://www.alexfeinman.com/dow­nload.asp?doc=PowerAwareApp.zi­p.

If it is related to the connection timing out, try sending a dummy
packet to the server every 10 minutes or so.

To automatically dial, P/Invoke RasDial and look in the serial classes
of OpenNETCF.

If you have administrator access to the VPN server, and it's a Windows
machine, you change/disable the amount of time the server waits before
disconnecting. You probably do the same thing with a Linux box, but I don't
know. If you need instructions on how to do it for a Windows 2003, let me
know.
