DJBDNS in 2 minutes!

Here's how to setup djbdns in 2 minutes:

On a machine that has a standard Linux installation like Fedora Core, run the following commands in a script with proper arguments:

#!/bin/bash
# $1 is this server's IP address
# $2 is slave server's IP address to which you want to allow AXFR
# $3 is the domain for which you want to allow AXFR

# Installs daemontools
mkdir -p /package
chmod 1755 /package
cd /package
echo " Getting daemontools-0.76 from cr.yp.to "
wget http://cr.yp.to/daemontools/daemontools-0.76.tar.gz
gunzip daemontools-0.76.tar
tar -xpf daemontools-0.76.tar
rm -f daemontools-0.76.tar
cd admin/daemontools-0.76
echo gcc -O2 -include /usr/include/errno.h > src/conf-cc
echo " Starting compilation and installation "
package/install
# Installs ucspi-tcp-0.88
mkdir -p /package
chmod 1755 /package
cd /package
echo " Getting ucspi-tcp-0.88 from cr.yp.to "
wget http://cr.yp.to/ucspi-tcp/ucspi-tcp-0.88.tar.gz
gunzip ucspi-tcp-0.88.tar
tar -xf ucspi-tcp-0.88.tar
rm -f ucspi-tcp-0.88.tar
cd ucspi-tcp-0.88
echo gcc -O2 -include /usr/include/errno.h > conf-cc
echo " Starting compilation and installation "
make
make setup check
# Installs djbdns
mkdir -p /package
chmod 1755 /package
cd /package
echo " Getting djbdns-1.05 from cr.yp.to "
wget http://cr.yp.to/djbdns/djbdns-1.05.tar.gz
gunzip djbdns-1.05.tar
tar -xf djbdns-1.05.tar
rm -f djbdns-1.05.tar
cd djbdns-1.05
echo gcc -O2 -include /usr/include/errno.h > conf-cc
echo " Starting compilation and installation "
make
make setup check
echo " Installations Done!"
echo " Configuring tinydns "
useradd -r -s /sbin/nologin -l -M Gtinydns
useradd -r -s /sbin/nologin -l -M Gdnslog
tinydns-conf Gtinydns Gdnslog /etc/tinydns $1
ln -s /etc/tinydns /service; sleep 5; svstat /service/tinydns
echo " Configuring axfrdns"
useradd -r -s /sbin/nologin -M -l Gaxfrdns
axfrdns-conf Gaxfrdns Gdnslog /etc/axfrdns /etc/tinydns $1
ln -s /etc/axfrdns /service; sleep 5; svstat /service/axfrdns
echo ':allow,AXFR=""' > /etc/axfrdns/tcp
echo $2':allow,AXFR="'$3'"' >> /etc/axfrdns/tcp
echo " Checking process "
ps fo pid,ppid,rss,bsdstart,etime,euser,args p `pgrep "svscan|multilog|tinydns|readproc|supervise|tcpserver" `
echo " Checking listening ports "
netstat -natunee  grep 53
echo " Completed! "

At the end you must see an output similar to this:

This indicates that your installation was successful. If there were any failures, let me know.

Viola, your server is up and running. It's rock solid and can easily handle lots and lots of requests and domain records.

You can install a web interface like vegadns that uses php/mysql to add/remove/modify records. But I recommend learning how to edit data file directly. It's very easy and quick to modify.
