Hi Grant,

There must be some other issue that's causing the return code 127.  I'm 
not too familiar with the system you're using - is it Solaris?  Does the 
"*" next to check_nrpe in your "ls -l" output mean anything significant?

Also what are the permissions on /usr/lib/nagios/plugins and all parent 
directories?  What do you get if you "su nagios" (or whatever user your 
Nagios system runs as) and do "/usr/lib/nagios/plugins/check_nrpe --help" ?

Lastly, from the Nagios interface, select View Config and Commands - 
what is your check_nrpe command-line?  If it contains a $USERx$ macro, 
what's the value of that macro (in etc/resource.cfg) ?
