CHECK_NRPE: Error receiving data from daemon

[mesobranlaspalabras]

Hi guys,

I installed Nagios Core 4.3.2 server and client. In client when i try to execute this : /usr/local/nagios/libexec/check_nrpe -H localhot -n, the answer is this CHECK_NRPE: Error receiving data from daemon.

I have revised:

-firewall/iptables: it's desactivated

- nrpe.cfg:

#server_address=127.0.0.1
]nrpe_user=nagios
nrpe_group=nagios
allowed_hosts=127.0.0.1

- user and group

nagios500:500::/home/nagios:/bin/bash
nagios500:

drwxrwxr-x. 2 nagios nagios 4096 ago 10 13:41 libexec
drwxrwxr-x. 2 nagios nagios 4096 ago 10 13:52 etc
-rw-r--r--. 1 nagios nagios 7,9K ago 10 13:49 nrpe.cfg

-xinetd
[root@SrvNagiosCore-cliente xinetd.d]# cat nrpe.xinetd
# 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 = 127.0.0.1 192.168.100.67
}

I can't find the cause of problem.

Best regards!

Someone can help me?

Are you running nrpe as a daemon (service) or as a xinetd service?

try

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 127.0.0.1

This may be a dns resolution issue for localhost
