NRPE no output returned from plugin

You could try these two tips from the faq to see if your configs have
errors:

Subject: [Nagios-users] NRPE no output returned from plugin

So I'm having a bit of trouble setting up NRPE for the first time.
I'm fairly certain things are working as intended on the remote host
because from the Nagios system I can do this:

$ /usr/lib/nagios/plugins/check_nrpe -H my.host.name -c check_disk_root
DISK OK - free space: / 14843 MB (50%);|

But when Nagios attempts to check this, it reports "(No output
returned from plugin)".

In my services.cfg file, I'm trying to use this service (copied from
other working services that only specify the "use", "host_name",
"service_description" and "check_command" lines):

define service{
    use             generic-service
    host_name           my.host.name
    service_description     / Free Space
    max_check_attempts      3
    normal_check_interval       5
    retry_check_interval        1
    check_command           check_nrpe!check_disk_root
    }

Nagios is running on an updated debian box with everything installed
via apt, but the remote system is running Red Hat Enterprise Linux 3,
and had NRPE and its dependencies installed via rpm.

Any suggestions for how I should go about troubleshooting something like
this?

I'd really appreciate any pointers that come to mind!  Thanks!

Tom
