Monitoring VPNS's

[bytesize]

Hi guys,

I have several remote agents running on servers in satellite offices, and I would like to be able to monitor whether there is VPN connectivity between the two agents on private network addresses adn then create a trigger when it goes down.

Is this possible?

Thanks!

Is your VPN server running on Linux? I run a Linux gateway with VPN connections. I would do something like that:

Write a small script, maybe:
ifconfig | grep 10.100.100.210 | wc -l
The IP is your VPN p-t-p IP for the remote server. The output of this line is 0 or 1. 0 means there is no connection to the server, 1 means connection is established. Set up an UserParameter that runs this script, and you get the result (0 or 1).

a simple ping to the remote device would probably be fine.

Hello,
I'm trying to find the correct OID to ask Cisco VPN router to tell me if the tunnel is up via SNMP. If I found something I'll post here.

that would be great but my research did not respond in great results... i looked into the MIBfile of Cisco and could not find anything releated to VPN tunnels...
