Check SonicWALL VPN

Project Notes
This script will enumerate via SNMP the currently active VPN's. It will then test against the specified VPN name to see if the VPN is active or not. If it is, it will return OK otherwise it will return CRITICAL. This script also has the ability to list the currently active VPN's on the SonicWALL. Usage: check_vpn.pl -H host -C community -V vpn_name check_vpn.pl -H host -C community -V LIST_ALL_VPNS define command { command_name check_vpn command_line $USER1$/check_vpn.pl -H $HOSTADDRESS$ -C $ARG1$ -V "$ARG2$" } On a host: check_vpn!community!VPN

VPN name issue
by fongang_valery, March 31, 2012

Scripts works well except that there is a little issue in the code. As it is the script will be able to list VPNs correctly but when checking a given VPN connection name, it will report VPN down even when the VPN is up. The issue here is that in the script the is a space " " added to the name value you pass on command line. To solve this modifiy the script as follows: - search for: elsif ($name eq $vpn) - replace with: elsif ($name eq $vpn." ") It should just a single replacement somewhere at the end of the script.


Works, but...
by prestigetech, January 31, 2012

The plugin works, but seem quirky and can't figure out why. Also, had to install the Net::SNMP perl module which was a fairly straightforward process. The quirkiness seems to be related to the VPN name somehow. I had a VPN tunnel named after the peer VPN Sonicwall ID and the script gave me an error that "VPN 012A345B678D is DOWN" even though the tunnel was not down. I renamed the tunnel to "My Home" and it worked as expected. Very strange.
