Falko, This is an awesome guide that I will use to my advantage. I always wanted to manage my own DNS for my organization. However, I do have a few questions. When setting up Debian Perfect, will the hostnames be the usual server1 and server2.domain.com respectively and do they need to be a FQDN? When setting up ISPConfig, where it says: Please enter the host name: E.g. www Please enter the domain: E.g. xyz.de Dose the name need to be the same for both servers or should I use server1 and server2.domain.com respectively? I noticed that you're using 2 ISPConfig servers for this setup, one as Master DNS and the other as Slave. I understand that if one goes down, the other picks up. So this is a redundant setup, which I love. Is this redundancy only for DNS or does it apply to the entire ISPConfig data? If that's not the case, would I be able to apply your guide, Mirror Your Web Site With rsync and How To Set Up Database Replication In MySQL , to the ISPConfig servers? I would like to have a setup that does website/mysql replication also, therefore if one of my ISPConfig server should go down, the other will take over. This will do for a complete redundant setup. Is that possible?
