puzzling no output from nrpe run of check_load

[Peter N. Steinmetz]

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 password-less login (a ! character for the password field in /etc/shadow), but the shell set to /bin/false, so no logins can take place. 

After setting a password for user nagios on both the server and the remote nrpe server, and setting a shell such as /bin/bash, the system seems to work. 

So why is it that proper functioning of the check_load plugin on the nrpe server requires a shell? and password for login? It does seem that the more correct method of operation is a non-login shell with permissions set appropriately in /etc/sudoers, but somehow that is not working.

thanks,
Peter
