Question

Where to locate the synced DNS zones from the Master DNS server?

Answer

The location of the DNS zone files depends on the Slave DNS server configuration and OS: the DNS zone files may be stored either in ordinary text files or in a database file.

For example:

• On RedHat/CentOS: if it’s installed the
bind-chroot package on the Slave DNS server, the BIND service will run in the
/var/named/chroot
environment and all configuration files will be there. As such, zone files can be found in
/var/named/chroot/var/named path.

• On Debian/Ubuntu: If it’s installed the bind9 package on the Slave DNS server, the BIND service will create database files in /var/cache/bind folder path. For example, to retireve the DNS zone from domain example.com and store its output in the file example.com.txt:

  # named-compilezone -f raw -F text -o example.com.txt example.com /var/cache/bind/example.com
  # cat example.com.txt
