NRPE agent not working on Oracle Linux 7

[hkang]

I already corrected the typo. Still got the same message.

-bash: /usr/local/nagios/libexec/check_nrpe: No such file or directory

There is no check_nrpe in that dir.

[hsmith]

Can you show us the contents of that directory? Did you install the nagios-plugins? If you haven't done that, you're most likely going to want to.

[hkang]

I installed NRPE agent (linux-nrpe-agent.tar.gz). I guess it is different from NRPE plugin (nrpe-2.15.tar.gz).

Here are the contents in that dir:

[hsmith]

I'm surprised it's not in there. What's the output of a find / -name check_nrpe command?

[hkang]

Nothing is returned for that command.

[hsmith]

What is the output of the following command?

Code: Select all

ls -lR /usr/local/nagios

[hkang]

It's a long list:

What is the output of a netstat -pant | grep 5666 command?

[hkang]

Nothing was returned.

[hsmith]

I don't believe NRPE was fully installed, then. Do you still have the install.log file sitting around somewhere that we could review?
