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

[Andy Shellam]

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.)
