I am running nagios 3.2.1 on debian squeeze. I am succesfully executing /usr/lib/nagios/plugins/check_http --ssl -H xxx.xxx.xx.xxx -I xxx.xxx.xx.xxx -N form machine that . However, when I used the same on the server, I get

I am succesfully executing /usr/lib/nagios/plugins/check_http --ssl -H xxx.xxx.xx.xxx -I xxx.xxx.xx.xxx -N form machine that . However, when I used the same on the server, I get

This does not make much sense, in which case is this plugin working and in which case is it not? What is the difference?

I didn't mention the topology

iis server =============== sonicwall firewall ============ WAN =============== cisco firewall ================== debian squeeze running nagios

From debian squeeze's command line I am successfully executing /usr/lib/nagios/plugins/check_http --ssl -H xxx.xxx.xx.xxx -I xxx.xxx.xx.xxx -N

However, from the same machine, based on the configuration the same command is not successful. I looked at debug and it appears nagios3 is trying to ping the machine. I am not sure why as all I want to do is check_http.

sorry for the bother.

I figured out the problem. It appears that nagios check the status of a host by default by pinging it. After changing the check command everything is working.
