In the screen shot from your first post showing the errors is trying to use this IP address 192.168.1.23 and not the other 2 that you posted the information for.
Verify that it is the correct IP address you want to check and if so, post the output from the same commands you ran on the other 2 systems.

thanks tgriep.

what i provided yesterday is correct.

it 192.168.1.22 and 192.168.1.24.

I'm not understanding why 24 or 22 tells me that the other host is down.

***** Nagios XI Alert *****

If i click on "Force an immediate check" in the attached page, then it comes back with a green tick.

Similar for "Ping this host".

Can you login to the server at IP address 192.168.1.24, run the following command and post the output? For all of the other errors when running the NRPE checks, take a look at this guide for solutions to the errors you are having.

Can you post the configuration settings for the host check that is giving you the socket timeout after 10 seconds?
The command from my previous post, you could use for the host check and is should work for you.

From server 24 running the command.

We need to see the actual host / service definitions.
