Nagios Support Forum

The IP address of the nagios server is in the allowed hots entry, I restarted the service anyway.

The commands were run:

[ronb@nagios ~]$ nmap 64.5.130.146 -p 5666

Starting Nmap 6.47 ( http://nmap.org ) at 2018-05-18 13:15 EDT

CHECK_NRPE: Socket timeout after 10 seconds.


I will have to wait until our web guy is back in the office and ask him to open the ports I need. I will update once these are successful.

Sounds good. Let us know what you found. We will keep the thread open for the time being.

Can you let me know what ports I need them to open, 5666 and there was a 12648 (something like that) for a windows server, not sure if that is needed on a linux box.

Thank you

For NSClient++ (Windows) you need to open 12489 (for check_nt) and 5666 (for check_nrpe). For the Linux box you only need to open 5666.

Thank you, I will report back when ports have been opened.

Noted.

We are going to get port 5666 opened today and I will report back if all is well. Fingers crossed.

Sure. Let us know how it went.
