So, first we need to download and extract dnrd:
# wget http://downloads.sourceforge.net/dnrd/dnrd-2.20.3.tar.gz
# tar xvfz dnrd-2.20.3.tar.gz
Next, install a compiler:
# apt-get install gcc
# apt-get install g++
# apt-get install make
Next, configure the package:
# ./configure
Compile and install the package:
# make
# make install
Create a startup script (/etc/init.d/dnrd)
#! /bin/sh
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="Domain Name Relay Daemon"
NAME=dnrd
DAEMON=/usr/local/sbin/$NAME
PIDFILE=/var/run/$NAME.pid
OPTIONS="-s 195.130.131.10 -s 195.130.130.5 -a 192.168.1.254"
# Gracefully exit if the package has been removed.
test -x $DAEMON || exit 0
#
# Function that starts the daemon/service.
#
d_start() {
start-stop-daemon --start --quiet --pidfile $PIDFILE \
--exec $DAEMON -- $OPTIONS
}
#
# Function that stops the daemon/service.
#
d_stop() {
start-stop-daemon --stop --quiet --pidfile $PIDFILE \
--name $NAME
}
#
# Function that sends a SIGHUP to the daemon/service.
#
d_reload() {
start-stop-daemon --stop --quiet --pidfile $PIDFILE \
--name $NAME --signal 1
}
case "$1" in

echo -n "Starting $DESC: $NAME"
d_start
echo "."

stop)
echo -n "Stopping $DESC: $NAME"
d_stop

echo -n "Restarting $DESC: $NAME"

sleep 1

# echo "Usage: $SCRIPTNAME {start|stop|restart|reload|force-reload}" >&2
echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
exit 1

exit 0
Add a user for dnrd
# adduser --system dnrd
Configure dnrd; create and edit /usr/local/etc/dnrd/master
domain earth
192.168.1.1 localhostname
192.168.1.254 firewyse
Start dnrd using the script we created earlier:
/etc/init.d/dnrd
Test your nameserver:
# nslookup firewyse
Server: 192.168.1.254
Address: 192.168.1.254#53
Non-authoritative answer:
Name: firewyse.earth
Address: 192.168.1.254
As you can see, dnrd is able to resolve the earth domain. Adding additional hosts from your local network is accomplished by adding additional entries in the /usr/local/etc/dnrd/master file. All you need to do is maintain one single configuration file. Configuring bind to do this, requires a lot more additional steps and configuration files.
Finally, we need to make sure dnrd starts when the system is booted:
# update-rc.d dnrd defaults
Adding system startup for /etc/init.d/dnrd ...
/etc/rc0.d/K20dnrd -> ../init.d/dnrd
/etc/rc1.d/K20dnrd -> ../init.d/dnrd
/etc/rc6.d/K20dnrd -> ../init.d/dnrd
/etc/rc2.d/S20dnrd -> ../init.d/dnrd
/etc/rc3.d/S20dnrd -> ../init.d/dnrd
/etc/rc4.d/S20dnrd -> ../init.d/dnrd
/etc/rc5.d/S20dnrd -> ../init.d/dnrd
