version 4.0.0: Warning: Return code of 13 for check of...

[Florin Andrei]

I've built RPM packages from 4.0.0 for core, plugins and NRPE, and I've installed them on Red Hat 5. I'm using a simple test configuration with a few hosts and services. This stuff used to work on 3.x. Now I get a whole lot of:

Code: Select all

[1381794997] Warning: Return code of 13 for check of host 'foo' was out of bounds.
[1381795002] Warning: Return code of 13 for check of host 'bar' was out of bounds.
[1381795007] Warning: Return code of 13 for check of host 'baz' was out of bounds.

And same code 13 for a few select services. Funny thing is, some services work just fine.

The check_command for hosts is check-host-alive, which is then defined as:

Code: Select all

command.cfg:command[check-host-alive]=/usr/lib/nagios/plugins/check_ping -H $HOSTADDRESS$ -w 5000,100% -c 5000,100% -p 1

If I run that thing manually, either as root or as nagios, it's fine.

I know it's supposed to be a matter of permissions, I just can't figure out what exactly. I've checked file ownership, it's nagios:nagios in most places in /var used by this service:

Code: Select all

SELinux is set to "permissive".

Any tips or clues? I've looked everywhere, I'm stumped.

What version of the plugins package did you install along side 4.0?

[Florin Andrei]

Code: Select all

# rpm -qa | grep -e nagios -e nrpe
nagios-4.0.0-2
nagios-plugins-1.4.16-1
nrpe-plugin-2.15-1
nagios-contrib-4.0.0-2

[Florin Andrei]

After quite a bit of difficulties (spec file is broken, there are many things not right about the whole package compiling here), I've managed to build an RPM package out of nagios-plugins-1.5. I've upgraded that package on the test server, restarted the nagios service, and I'm getting the same errors.

"Warning: Return code of 13 for check of host..."

Any suggestions would be appreciated.

Is this error only occurring on "check_ping" checks?

[Florin Andrei]

No, it's multiple plugins.

Meanwhile, I think I've found the problem. The spec files for the RPM packages, contained in the tarballs, are woefully out of date, and incompatible between nagios, nagios-plugins, and nrpe-plugin. Also, there are things such as 644 permissions on directories, etc. It's ugly.

I'll fix the specs and open a new thread, detailing my findings and the fixes. I'll link it here.

EDIT: Okay, I have what seem to be clean specs that build compatible packages. I'm a little busy now (Tue Oct 22 17:44:49 PDT 2013). I'll make a note to post my findings tomorrow.

EDIT2: I've posted all of my findings here:

Feel free to close this old topic, the new topic is much more extensive and also contains fixes.

Great, we will leave the thread open awaiting your final post.
