FreeBSD DJBDNS: Create Secondary TinyDNS Server

To create a secondary TinyDNS server using DJBDNS on a FreeBSD system, you will need to do the following:

1. Install DJBDNS on your FreeBSD system. You can install DJBDNS using the pkg package manager:

# pkg install djbdns

2. Create a user and group for the TinyDNS server to run under. You can do this using the pw command:

# pw groupadd tinydns
# pw useradd tinydns -g tinydns -d /usr/local/tinydns -s /nonexistent -w no

3. Set up the directories and configuration files for TinyDNS. Run the following commands to create the necessary directories and files:

# mkdir -p /usr/local/tinydns/secondary/data
# mkdir /usr/local/tinydns/secondary/log
# cd /usr/local/tinydns/secondary
# touch log/main
# touch log/status
# touch data/data.cdb
# cp /usr/local/djbdns/tinydns-data/secondary/Makefile .

4. Set up the DNS data for TinyDNS. You will need to create a DNS data file that specifies the DNS records for your domain. This file should be in a specific format, as described in the TinyDNS documentation. You can use the tinydns-data utility to generate this file from a template.

5. Run the make command to compile the DNS data file and create the necessary database files:

# cd /usr/local/tinydns/secondary
# make

6. Set up the TinyDNS daemon to start at boot time. You can do this by adding the following line to the /etc/rc.conf file:

tinydns_secondary_enable="YES"

7. Start the TinyDNS daemon:

# service tinydns-secondary start

8. Test the configuration by querying the TinyDNS server using the dig command:

# dig @localhost example.com

This should return the DNS records for the domain example.com.
