Power DNS is an OpenSource DNS project that uses mysql and that can be found at www.powerdns.org.

We have two servers running power dns:
hpcfns1.hpcf.upr.edu primary 136.145.54.10
hpcfns2.hpcf.upr.edu secondary 136.145.54.11

Installing pdns

Power dns may be installed from an rpm or tar ball.
From rpm: rpm -Uvh pdns-x.x.rpm
From tar: ./configure ; make ; make install

Configuring pdns

Edit the file pdns.conf
Set in their respective sections
default-soa-name=hpcf.upr.edu   #Our soa name
disable-tcp=no                  #Allow TCP queries
local-address=136.145.54.10     #The ip hpcfns1 binds
local-port=53                   #Default dns port
master=yes                      #This is in the hpcfns1
recursor=136.145.54.100:5353    #The dns you want to be our recursor (See datails bellow)
smtpredirector=mail.hpcf.upr.edu #Our smtp server(mail server)

The recursor is a dns that resolve domain names from the outside word. We are running bind (named) in the master dns server in another port to have our recursor.
