You may get an error like this while configuring nrpe with nagios
root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H x.x.x.x
CHECK_NRPE: Error - Could not complete SSL handshake.
root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H localhost
CHECK_NRPE: Error - Could not complete SSL handshake.

The problem is you didnt give the ip address in /etc/xinetd.d/nrpe

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# vi /etc/xinetd.d/nrpe

# default: on

# description: NRPE (Nagios Remote Plugin Executor)

service nrpe

{

        flags           = REUSE

        socket_type     = stream

        port            = 5666

        wait            = no

        user            = nagios

        group           = nagios

        server          = /usr/local/nagios/bin/nrpe

        server_args     = -c /usr/local/nagios/etc/nrpe.cfg --inetd

        log_on_failure  += USERID

        disable         = no

#       only_from       = 127.0.0.1

        only_from       = x.x.x.x 127.0.0.1  #give ip address of the server here(nagios server) and localhost

}

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# 

Now restart and check

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# vi /etc/xinetd.d/nrpe

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]#  service xinetd restart

Stopping xinetd:                                           [  OK  ]

Starting xinetd:                                           [  OK  ]

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H localhost

NRPE v2.12

root@server1 [/opt/Nagios/Nagios_NRPE/nrpe-2.12]#
