Thanks smith!
Also, please show us the check_nrpe command you are running for Core along with the output.
It's possible you'll find

Okay, I will try that. I ran cat for /etc/passwd and nagios is listed as:
Code: Select all
nagios:x:123:131::/var/lib/nagios:/bin/false
^On the remote machine
Could this have any affect on the issue?

The following is the format I would like to see:
Code: Select all
root@nagios:/usr/local/nagios/libexec# ./check_nrpe -H REMOTEHOST -c inxi
output
Also, there's nothing referencing
inxi in your nrpe.cfg, so that will need to be corrected.
Yes, the nagios user should have /bin/bash (or wherever bash is installed).

I cannot su in the nagios user, after I entered its password I remain as the same user. Do I need to install Nagios Core on the remote machine? Or do I just need to add a user named nagios?
Also, is the line you created what I should have for the nagios command?

You need to change
nagios
123:131::/var/lib/nagios:/bin/false to
nagios123:131::/var/lib/nagios:/bin/bash, or, again, wherever bash is installed. What is the output of
which bash?

The output is /bin/bash
How would I go about changing nagios
123:131::/var/lib/nagios:/bin/false to nagios
123:131::/var/lib/nagios:/bin/bash?

You could run this command as root to change nagios login shell to /bin/bash.

Thanks
@tgriep, change successful.
@dwhitfield where do you want to see this?
Code: Select all
root@nagios:/usr/local/nagios/libexec# ./check_nrpe -H REMOTEHOST -c inxi
output

I think he wants you to run the command on the Nagios server and replace REMOTEHOST with the IP address on the system you want to run the inxi command.
One thing, I did not see the command defined in the nrpe.cfg file. Did you define it in another config file?

The inxi command is printing out different colors for the text and that is causing the issue.
Edit your command and add the following option to the command that is defined in nrpe and that should fix the issue.
The -c 0 option sets the color scheme to none.
123:131::/var/lib/nagios:/bin/false
