This simple script converts the content of tinydns' data file into separate zone files - one zone file per domain. The major conversion is done by the axfrdns program which is part of djbdns.

• Access to tinydns' data file - the script below assumes its location in /etc/tinydns/root. If it is located in a different path simply adjust the script.
• axfrdns program running

Use axfrdns-conf. Make sure that the user account gaxfrdns and the group gdnslog exists. The following lines will set up axfrdns to listen on 127.0.0.1 and to control the process via daemontools.

axfrdns-conf gaxfrdns gdnslog /etc/axfrdns /etc/tinydns 127.0.0.1
ln -s /etc/axfrdns /etc/service

#!/bin/bash

set -e
cd /etc/tinydns/root
