What is fw1vpntools
These are some little nifty helpers, which we are using for monitoring and
maintaing a bunch of VPN's terminated at two clustered Firewall at my
employer. Due to some strange SLA's we have to monitor the availabilty
of the affected VPN. Since the opposite side doesn't allow active monitoring
of resources on their site the check_vpn tool reads some CheckPoint FW-1 Tables
and checks for the IKE SA and in and outgoing SPI to the corresponding peers.
check_vpn
check_vpn is a monitoring plugin for Nagios (see http://www.nagios.org/).
check_vpn reads the VPN-1 Rulebase for list of monitored peers and checks
for all peers the presence of IKE SA's and In-/Outgoing SPI's in the VPN-1
tables. Since we have a setup with 2 Firewall Clusters with 4 Nodes
check_vpn is able to check all nodes at once.
vpnstatus
vpnstatus displays all VPN IKE SA and SPI's in human readable form.
the output contains the IP address, object name in the rulebase, monitoring
indicator, sum of IKE SA and SPI's on all firewall nodes, and the number of
IKE SA's and SPI's for each firewall node.
remarks
Both tools needs some time for processing, for our setup with 2 Firewall
Clusters with 4 Nodes and a Object-Database with about 500 Objects it takes
about 15 sec to get a result from the tools. 7 seconds are needed for reading
the Object database and the rest is needed for reading the tables from the
"fw tab" util.
