Continuing with this debugging. I think I understand the point about needing a
shell permission to write output to the terminal window.
I've now replaced the shell on the remote host with /bin/false and eliminated
the password for the nagios user on the remote machine. If I leave the password
Thanks for the suggestion, gave that a try, or more precisely:
sudo su nagios -c more /proc/loadavg
after removing the password for user nagios and setting the shell to /bin/false.
This still produces no output.
Very peculiar. I guess there must be something wrong with the authentication or
so it seems that the check_load needs shell rights to show any output
what so ever also the --help stuff.
it's kind of understandable.

Yes, ls -l /proc/loadavg shows:
-r--r--r-- 1 root root
which I believe mean any user can read it.
Yet,
sudo su - nagios more /proc/loadavg
returns nothing when the nagios user has /bin/false for a shell, and returns
the expected output when the nagios user has /bin/bash for a shell.

Some more information and experimentation today.
After reading the NRPE manual, I noticed that they refer to being able to log
in as the nagios user and having a password.
The configuration which is established by the package installations under
ubuntu are to have the nagios user allowing
