While i was waiting for your answer, i tried also your guide "The Perfect Server - Debian Squeeze (Debian 6.0) With BIND & Dovecot [ISPConfig 3] ". Again a lot of problems. Then i found the cause - bad HDD. Changed it - Debian installed with no problem
Have another question dough:
i'm trying to set up slave DNS. I'm using "How To Run Your Own DNS Servers (Primary And Secondary) With ISPConfig 3 (Debian Squeeze)".
Should i follow instructions in the first guide also for slave up until ISPConfig3 installation and continue from second guide from "3 Setting Up server2.example.com (Secondary DNS)"?
What about forwarding?
Both, master and slave, would be on the same subnet. For master, i forwarded port 53 on my router to the master. Should i do the same for slave?
Last question: at the end there will be master dns with mail, mysql, ftp,... and slave that is a mirror of a master (but just DNS). What about mirroring other services (web pages, mail...)?
