Hi there, we’ve installed Libreswan on a Rhel7 host and have the ipsec service running on UDP port 4500. Am trying to run a nagios check_udp command from another host to make sure it’s running. The check_udp command requires a send and an expect string. I’m not sure what those would be for this service and was hoping you could help me there? Thanks!
This is very tricky as it depends on configurations. For example, if you have a static IP to IP tunnel, the nagios server with a different IP will not be able to send anything and get a reliable response. You could try netcat/socat send a similar packet, although you would also clutter the logs with errors I would do something like "ssh root@ipserver ipsec status" as test.
