Dear all, I have installed nrpe on my nagios host and one client host. On Nagios Host: 1.)I compiled nrpe and copied the check_nrpe plugin to /usr/local/nagios/libexec/ directory On client host: 1.)I compiled the nrpe and then copied the nrpe.cfg in /etc/ 2.)Also placed /etc/xinetd.d/nrpe and placed the user as root in it and the allowed hosts as the Nagios host 3.)Started the xinetd daemon Now i noticed two things: Firstly when i try to telnet client_host 5666 from nagios_host it gives following ################ [root@nagios libexec]# telnet 203.187.192.44 5666 Trying 203.187.192.44... Connected to 203.187.192.44 (203.187.192.44). Escape character is '^]'. Connection closed by foreign host. ################ Secondly when i try to run the check_nrpe daemon from within the /usr/local/nagios/libexec/ directory in Nagios_host it gives: ################ ./check_nrpe -H 203.187.192.44 -c check_load CHECK_NRPE: Error - Could not complete SSL handshake. ############### The copy of nrpe.cfg in client host is as follows: ################################# server_port=5666 command_timeout=60 # The following examples use hardcoded command arguments... command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10 command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20 command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p /dev/hda1 command[check_disk2]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p /dev/hdb1 command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200 ################################## The rest of the parameters in nrpe.cfg file are either not applicable b'cos i am using /etc/xinetd.d/nrpe or they are commented. Pls suggest. Thanks.
