ERROR: CHECK_NRPE: Socket timeout after 10 seconds

Question

getting following error :

# /usr/local/nagios/libexec/check_nrpe -H nagios-server-ip
CHECK_NRPE: Socket timeout after 10 seconds.

But it's working for localhost

# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.15

ps i have checked security groups as well as iptables

Also on Nagios server :

# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.13
[root@ADM-PROD-NAGIOS ec2-user]# /usr/local/nagios/libexec/check_nrpe -H monitoring-host-ip
NRPE v2.15

do you have nagios client running in the remote machine? Do you have opened 5666/tcp alllow Nagios IP in the AWS console firewall? — Rui F Ribeiro, Nov 25 '15 at 10:55
I guess # /usr/local/nagios/libexec/check_nrpe -H localhost NRPE v2.15 this on remote hosts proves nagios client is running on remote machine — Ashish Karpe, Nov 25 '15 at 10:59

There are two thing in nrpe.cfg.

allowed_hosts
server_address

In allowed_host we should mention public IP of Nagios server if it is outside the LAN.

In server_address we should mention the IP of the local machine which is to listen nrpe, because we might have multiple ethernet ports enabled and IPs associated with it.
