Hi,
I installed the nsclient++ (NSCP-0.5.0.62-x64) on a host (windows server) I want to monitor.
Here's my problem when I run check_nrpe from Nagioserver
Code: Select all
[root@nagiosxi ~]# /usr/local/nagios/libexec/check_nrpe -H 172.16.12.14 -n
connect to address 172.16.12.14 port 5666: Connection refused
connect to host 172.16.12.14 port 5666: Connection refused
Port 5666 is opened on host's firewall
Please find attached the nsclient.ini
Please help me.
Frederic

You are passing "-n" flag to check_nrpe, basically saying "Do not use SSL"... In this case, you should change this line:
to this:
in the nsclient.ini, and restart NSClient++ service.
Let us know if this helped.

Hi,
Thanks, but sorry, that doesn't solve my problem.
/usr/local/nagios/libexec/check_nrpe -H 172.16.12.14 -n or not gives the same error

I took a look as the nsclient.ini file and it looks like the the Windows server had an older version of the NSClient and then the newer one was installed over it.
Well, it looks like the upgrade corrupted the settings in nsclient.ini file.
I suggest uninstalling the NSClient++ agent from the server and deleting the files leftover in the following folder.
Then reinstall the NSCLient++ agent by following these instructions.

When you do reinstall it, you will have to check the box next to the "Enable NRPE server" option so it will enable it on the server.

Hi,
Thanks, I solved my problem by :
1) Uninstalling my nsclient ++
2) Install and configure nsclient++ using :
