1. Get your IP numbers for Primary and Secondary DNS first.

2. Create a list of host names and correspondence IP addresses in /etc/hosts file

3. #mkdir /etc/named.data

4. #cd /etc/named.data

5. Create a file named param that will be used by hosts_to_named to create DNS data files
Ex. -d bootabc.com
-n 192.168.18
-z 192.168.18.15
-b /etc/named.boot
-s
(-d = domain name, -n = network number, -z = configuration file for secondary server and IP no. of
primary server to download data files, -b for boot files used by named process, -s adds a name server
(NS) resource record in configuration file.

6. #hosts_to_named –f param

7. download the db.cache file from internet copy it to /etc/named.data directory

8. Modify /etc/rc.config.d/namesvrs file (NAMED=1) to start named process automatically with m/c

#vi /etc/rc.config.d/namesvrs

NAMED=1

3. copy db.127.0.0 from the primary server to /etc/named.data directory

4. copy db.cache from the primary server to the /etc/named.data directory

5. if you want to create local database files download the remaining files from /etc/named.data from
primary server to local /etc/named.data directory.

#vi /etc/rc.config.d/namesvrs

NAMED=1

then sav and exit

7. start named using /sbin/init.d/named start
