Re: Unable to connect to host error

I downloaded this file:
https://github.com/nagios-plugins/nagio ... 3.3.tar.gz
In the "tools" folder, this is what I see:
build_perl_modules build_perl_modules.in tinderbox_build

Re: Unable to connect to host error

In the instructions for compile+ install, one of the steps is as follows: "./tools/setup". But I don't see the setup file in the tar.gz in the tools folder.

Re: Unable to connect to host error

For some reason I see two configuration files:
/etc/nagios/nrpe.cfg
/etc/nrpe/nrpe.cfg

Which one do I want to update? Why are there two?

Re: Unable to connect to host error

I am not sure about that - how would I be able to tell? Let's do some troubleshooting. Run the following commands from the command line, and show the output: On the client (remote host): ip addr netstat -apn | grep 5666 /path/to/nrpe -H 127.0.0.1 -c check_procs -a '-w 400 -c 500' cat /etc/xinetd.d/...

Re: Unable to connect to host error

This seems to have fixed it for this one host. I then applied the fix for another host, and it is still broken. Here is the output of the command:
