Djbdns not included in Debian archives, but you can install djbdns - tinydns with following procedure:
Install the required daemontools, daemontools-run and ucspi-tcp packages first:
apt install daemontools daemontools-run ucspi-tcp
If you don’t have compiler toolchain, install it before going into djbdns compilation stage:
apt install build-essential
Now download djbdns source and build it:
wget http://cr.yp.to/djbdns/djbdns-1.05.tar.gz
tar xf djbdns-1.05.tar.gz
cd djbdns-1.05/
echo gcc -O2 -include /usr/include/errno.h > conf-cc
make
make setup check
Create the required users for tinydns and dnslog:
useradd --no-create-home --shell /bin/false Gtinydns
useradd --no-create-home --shell /bin/false Gdnslog
Create initial tinydns configuration:
tinydns-conf Gtinydns Gdnslog /etc/tinydns [DNS-SERVER-IP]
ln -s /etc/tinydns /etc/service
That’s all, it’s working:
ps uax | grep tinydns
