    No establece conexión de angente Zabbix en un Centos 7

    Hola , buenas a todos, he instalado el agente de Zabbix en un Centos 7 y he iniciado el servicio una vez configurado, pero tengo el problema que al iniciarlo no conecta con el servidor de Ubuntu que es donde tengo la web de Zabbix.

    [root@localhost etc]# service zabbix-agent status
    Redirecting to /bin/systemctl status zabbix-agent.service
    zabbix-agent.service - Zabbix Monitor Agent
    Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; enabled)

    ¿me podéis indicar que paso me falta para que pueda establecerse la conexión entre ambos? He desactivado la IPtables y el Firewall pero aun así no termina de completarse ni establecerse la conexión.
    Un saludo.

      Hola amigo,

      Creo que es un problem de conectividad, mira el servicio firewalld en CentOS 7 y haga los comandos a partir del server Zabbix.

      - para saber si el firewalld esta running

      firewall-cmd --state

      - para si hay conectividad.

      telnet 192.168.xxx.xxx 10050

      nc -n -v 192.168.xxx.xxx 10050
