Originall posted in the wrong place. Reposting here: Followed the tutorial for Debian, couldn't find one for centos 7 on multiserver. I did the multiserver setup for the slave server. My primary server lists the secondary server in the drop down selectors. However I see nothing on the slave that indicates it is receiving data. I also have warnings at the top of ISPConfig: The following changes are not yet populated to all servers: datalog_status_i_dns_slave: 1 datalog_status_u_dns_slave: 2 datalog_status_i_firewall: 1 datalog_status_u_server: 3 Under system state on the primary both servers are listed. Showing no Errors. Not sure what i've done wrong. On the primary under System > Server Services the slave server is set to be a mirror for DNS and web. I do not see the one zone I have created on the primary, on the slave server.
