I'm having trouble fully understanding how the DNS system works in general and with Virtualmin... in the past most of my sites have been hosted on shared hosting using cpanel or something similar. Iv not had to worry about setting up DNS all I had to do was add the domain on in cpanel and point my domain in godaddy to specified nameservers and it all worked fine and dandy!
Iv got a cheap VPS that's got Ubuntu 8.10 installed and updated and has two ip addresses. I basically got this VPS to play with a learn on before moving any live websites over to it.
So far iv managed to get virtualmin installed and working with the install script.
now comes the confusing bit for me.....
When setting this up it asked for a fully qualified domain name, does this mean it requires one of my actual registered domain names that I intended to use for a website? If so why?
I had planned to setup the VPS and host two completely separate sites each having its own IP address ( I know this isn't necessary) and domain name associated with it. But now Im not sure what to do, should I use the domain name of the main site as the host name? I'm kinda lost here...
can somebody explain to me in layman's terms how to set this up correctly, so that I will have working nameservers to point my individual domains names to that I will use for each virtual server.
