Hello  @stephanepainot 

Yes it’s linked.

On the central, you can try this command, after an export of the configuration:

systemctl restart cbd centengine gorgoned

And you read this article too: 

I tryed this command,  and exported  the configuration but the result is the same :” Not running”

I feel like I've tried everything...

Ok.
Did you read the article ?

Can you give the return of the latest /var/log/messages, /var/log/centreon-broker/central-broker-master.log ?

Yes I always read this article. It’s the same

I just extarct the last hour of log because it’s too long

/var/log/messages

Thank

Salut

Alors truc tout bête mais quand tu exporte la config du poller, il faut que tu t’assures que les cases soit cochées :

Et quels sont les status des 4 services que t’as listé Kriko ? 

EDIT: En tt cas tu est dans de bonnes mains avec Kriko :)

Peut être qeu cela peut aider :
 

Could you give me the output of the log /var/log/centreon-broker/central-rrd-master.log ?

Oui les cases sont bien cochées

et a priori sans erreur 

Concernant les services

What is the output of the following commands:

ss -plantu | egrep '(5669|5670)'
grep -ri segfault /var/log/messages
ps axuf | grep -i cbd

What is the result of 

systemctl status firewalld
getenforce
iptables -L

What is the hell.

Let’s me think twice.

Is it possible to give me the broker configuration ?

The files are /etc/centreon-broker/central-broker.json and /etc/centreon-broker/central-rrd.json

Ca me rassure

Problem solved:

there was not entry for localhost on 127.0.0.1

So localhost only resolv on ipv6 (::1).

And broker is configured to use ipv4 output.

We create a entry /etc/hosts for localhost on 127.0.0.1

I have edited the /etc/hosts file but I still have the same problem.

Which is the exact line did you add on hosts file? 

I put

127 0 0 1 local…host.

(that line with dots and second word all together)

and I have the same issue… No tcp connection to port 5670

Someone has any idea?

systemctl restart cbd centengine gorgoned

Thank you very much, that command solved our problem!!
