<p class=MsoNormal>Hi there, <o:p></o:p></p>
<p class=MsoNormal>I’m having issues when trying to check a plugin via
NRPE…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Whenever I run the check command, NRPE returns:<o:p></o:p></p>
<p class=MsoNormal>Unable to read output.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m lost… <o:p></o:p></p>
<p class=MsoNormal>The file permissions are correct, it’s executable and
owned by the Nagios user… <o:p></o:p></p>
<p class=MsoNormal>The script runs fine locally.<o:p></o:p></p>
<p class=MsoNormal>I have double and triple checked the command definition, and
that’s fine… <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For reference, here’s some output.<o:p></o:p></p>
