Hi cazz,
On the server running the agent: (green only or green,red)
# config set fw_zabbix service status enabled TCPPort 10050 access green
# signal-event firewall-adjust
# cat /etc/shorewall/rules | grep 1005*
ACCEPT loc $FW tcp 10050
# config show fw_zabbix
fw_zabbix=service
TCPPort=10050
access=green
status=enabled
Also: IP address of Zabbix server (mine is at 10.10.10.75) on the server running the agent, maybe no /24 but the exact address
# cat /etc/zabbix/zabbix_agentd.conf | grep ^Server
Server=10.10.10.75
ServerActive=10.10.10.75
Have a look at: https://www.micronator.org/affaires/produit/nethserver-401-cahier-03-zabbix-agents/
As usual Google translate is your friend !
If you don’t use discovery, you have to create the server on the Zabbix server. Look at page 25. BackupPC is the server running the agent.
