Usage: nrpe [-n] -c <config_file> [-4|-6] <mode>
Options:
-n = Do not use SSL
<config_file> = Name of config file to use
-4 = use ipv4 only
-6 = use ipv6 only
<mode> = One of the following operating modes:
-i = Run as a service under inetd or xinetd
-d = Run as a standalone daemon
-d -s = Run as a subsystem under AIX
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.
