Nagios Support Forum

HI Support,

I have 2 main issues with NRPE one is

I. I have successfully installed Nagios Core ver 4.0.4 in CentOS 6.6 64-bit server, which working properly. Now I want to add a new linux host for monitoring. As per the articles, I think its need NRPE plugin for adding linux host to Nagios core server. I have installed the NRPE plugin in remote host as per the article https://assets.nagios.com/downloads/nag ... _Agent.pdf .

Then tried to check whether it is working by passing the command in remote host ie /usr/local/nagios/libexec/check_nrpe -H localhost. Here i got one error which is
check_nrpe error - could not complete ssl handshake localhost . Nrpe working under xinetd. Xinetd service is still running. 5666 port already opened in iptables. nrpe is in listening mode also.

II . I have installed NRPE plugin in Nagios server through binary file which is downloaded from here; http://liquidtelecom.dl.sourceforge.net ... .15.tar.gz . I can successfully ran configure & make commands without any fail. after then am ran the same command for checking (/usr/local/nagios/libexec/check_nrpe -H localhost). Here also I am getting another error

-bash: /usr/local/nagios/libexec/check_nrpe: No such file or directory because of these errors still i cant able to add a single linux host to our monitoring system.

Your suggestions are very helpful to me... Kindly advice me the correct way to install and configure this and adding linux remote host.

Very very thanks in advance.

Just to clarify - are we talking about two different systems here?

1. Please run /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 and /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -n and post the result.

2. Where did you set your compile directory to when you installed NRPE? Did you install the Nagios Plugins?
