I have just installed nagios from the HPUX Internet Express cd, where it comes
as a depot. Running it locally, it comes up as V2.12. I added it to the
inetd.conf and services and forced inetd to recheck its config.
bash-3.2# grep -i nrpe /etc/*
/etc/inetd.conf:nrpe stream tcp nowait nagios /usr/bin/nrpe -c
/opt/iexpress/nagios/etc/nrpe.cfg --inetd
/etc/services:nrpe 5666/tcp # NRPE
When I telnet to the machine on the port, it throws back as if I had entered
the command with no switches at the machine prompt (included at end).
If I run it locally
bash-3.2# /usr/libexec/check_nrpe -H localhost -p 5666
CHECK_NRPE: Error - Could not complete SSL handshake.
So I try without ssl (even though openssl is installed)
bash-3.2# /usr/libexec/check_nrpe -n -H localhost -p 5666
CHECK_NRPE: Error receiving data from daemon.
Because when I telnet its giving the nrpe command, am I right in thinking for
somereason its not loading the conf file? If not, how can I remedy this
situation?

Usage: nrpe [-n] -c <config_file> <mode>
Options:
-n = Do not use SSL

<mode> = One of the following two operating modes:
-i = Run as a service under inetd or xinetd
-d = Run as a standalone daemon
Notes:
This program is designed to process requests from the check_nrpe
plugin on the host(s) running Nagios. It can run as a service
under inetd or xinetd (read the docs for info on this), or as a
standalone daemon. Once a request is received from an authorized
host, NRPE will execute the command/plugin (as defined in the
config file) and return the plugin output and return code to the
check_nrpe plugin.
