[Nagiosplug-help] (Return code of 127 is out of bounds - plugin may be missing)

[Grant Lowe]

Hi Andy,

Yes, I did those things.  Take a look:

nagios-test /usr2/glowe> locate check_nrpe
/usr/lib/nagios/plugins/check_nrpe
nagios-test /usr2/glowe> ls -l /usr/lib/nagios/plugins/check_nrpe
-rwxr-xr-x 1 root root 22064 May 16  2007 /usr/lib/nagios/plugins/check_nrpe*
nagios-test /usr2/glowe> 
/opt/csw> ps -ef | grep nrpe
   glowe 12374 11457  0 08:19:53 pts/4    0:00 grep nrpe
  nagios  6411     1  0   Oct 10 ?        0:00 /opt/csw/bin/nrpe -c /opt/csw/etc/nrpe.cfg -d
/opt/csw> 

Did I miss something?

Grant,

Have you checked the permissions of check_nrpe on your Nagios host as I 
suggested?  Also when running check_nrpe from the server's console, are 
you running it as the Nagios user?

Also check that the path to the plugin in Nagios is correct - return 
code 127 means the plugin doesn't exist, or cannot be executed (e.g. 
permissions.)
