Hi, I am trying to add a secondary server to my setup, and in this respect I followed this how-to http://www.virtualmin.com/documentation/dns/slave-configuration except it doesn't work and don't know why.
So, I have a master (Virtualmin) server wich runs everything and needed some redundancy. Installed on a backup system webmin and virtualmin gpl (and a fresh CentOS 6.3), changed the hostname (the hostname command shows the right name), registered the nameserver with my TLD, opened the ports 10001:10010, and the name resolves properly.
Now, when i try to add the slave server hostname to the master server in Webmin Servers Index this one doesn't let and keeps telling me "Error Failed to save server : Host does not exist". What is this non-sense of course it exists :) ?
If I add it with the IP it works, but it's useless for the later step of adding the slave to the Cluster Slave Servers... as it requires a hostname.
