Hello, I am trying to implement the check_tcp command to monitor if a specific port is closed on a host, and not open. This page https://www.monitoring-plugins.org/doc/man/check_tcp.html has a few options which I've tried, with zero success, including:
-r and -M and -e Basically, if the check can not connect to the port, that is the intended result. I am getting socket timeouts when I try the following from the nagios box itself to the host: ./check_tcp -H $HOST -p 8079 -r crit CRITICAL - Socket timeout after 10 seconds ./check_tcp -H $HOST -p 8079 -e "CRITICAL - Socket timeout after 10 seconds" CRITICAL - Socket timeout after 10 seconds ./check_tcp -H $HOST -p 8079 -M crit Can you put me in the right direction for getting this to work? Thank you, Brandon
