nrpe custom command problems

[Carroll, Jim P [Contractor]]

What user do you normally run nrpe from?  When you tested the plugin, did
you test it under that user?  Can you kick off your command from your Nagios
server using check_by_ssh?  (You'll need to set up a null passphrase in
order for this to work.)

What's the plugin written in?  If it's a /bin/bash script, try changing that
to /bin/sh .

Will the plugin run if invoked using 'at' or 'cron'?

Food for thought.
