Hi,
Hope you are having a good day.
Yes, just as I suspected. Your "nrpe" is installed at a different location.

Please run the below command on your "nrpe" agent machine as "root":

Code: Select all

ln -s /etc/nagios/nrpe.cfg /usr/local/nagios/etc/nrpe.cfg

ln -s /usr/sbin/nrpe /usr/local/nagios/bin/nrpe

Please edit the "/etc/nagios/nrpe.cfg" file.
Change:

Code: Select all

nrpe_user=nrpe

nrpe_group=nrpe

To:

Code: Select all

nrpe_user=nagios

nrpe_group=nagios

Now, restart xinetd:

Code: Select all

systemctl restart xinetd

Now, see if your "nrpe" is listening at port "5666":

Code: Select all

ss -na | grep 5666

Best Regards,
Vinh
