I have a Zabbix configuration problem here in the company a few days ago. I'm having this error on the hosts page in the Settings portion. I have already done several tests, being:
- Agent and Server Ports Release (Firewall Disabled)
- I changed the settings of agent.config and server.config.
- I disabled SELINUX.
If you can help me thank you, I only need this communication so I can proceed with the finalization of the installation.
Error: Received empty response from Zabbix Agent at [X.X.X.X].
Assuming that agent dropped connection because of access permissions.
I already looked for solutions in google but I did not find answers
I noticed that the server apparently has some network problem. I have managed to install normal zabbix using yum in Centos 7. However, the server is taking too long to ping google.com and is missing the settings in the resolv.conf file.
I do not know what this network problem can be, I'm a beginner in linux and I'm having a bit of trouble correcting this without having to configure a new server.
I identified that the server did not contain the google DNS (126.96.36.199) configured in:
/etc/sysconfig/network-scripts/ifcfg-eth0 so I added this registry and it solved the network problem, now it's ping google.com , before of this was only the internal DNS of the company. But the initial problem still persists and I think there may be some relationship with network configurations
