Primary DNS Server Configuration Part-3

Step-6: Copy, rename & change the ownership & permission of  localhost.zone file  for Forward lookup zone.

[root@ns1 ~]# cd /var/named/chroot/var/named/

[root@ns1 named]# cp localhost.zone alphabd.fz

[root@ns1 named]# chown root:named alphabd.fz

[root@ns1 named]# chmod 777 alphabd.fz

[root@ns1 named]# vi alphabd.fz

Original File:  localhost.zone

                           42         ; serial (d. adams)

                           3H         ; refresh

                           15M        ; retry

                           1W         ; expiry

                           1D )       ; minimum

           IN NS @

           IN AAAA         ::1

$TTL 86400

@          IN SOA     ns1.alphabd.net.       root.alphabd.net. (

                           2011022500 ; serial (d. adams)

                           3H         ; refresh

                           15M        ; retry

                           1W         ; expiry

                           1D )       ; minimum

         IN NS     ns1.alphabd.net.

ns1      IN A       210.207.201.1

Step-7: copy & rename the alphabd.fz  file  for Reverse lookup zone.

[root@ns1 named]# cp alphabd.fz alphabd.rz

[root@ns1 named]# vi alphabd.rz

Original File:  alphabd.fz

$TTL 86400

@          IN SOA     ns1.alphabd.net.       root.alphabd.net. (

                           2011022500 ; serial (d. adams)

                           3H         ; refresh

                           15M        ; retry

                           1W         ; expiry

                           1D )       ; minimum

           IN NS     ns1.alphabd.net.

ns1      IN A       210.207.201.1

Modified File:  alphabd.rz

$TTL 86400

@          IN SOA     ns1.alphabd.net.       root.alphabd.net. (

                           2011022500 ; serial (d. adams)

                           3H         ; refresh

                           15M        ; retry

                           1W         ; expiry

                           1D )       ; minimum

           IN NS     ns1.alphabd.net.

1        IN PTR     ns1.alphabd.net.

Step-8:  Edit the resolv.conf file by following this command

[root@ns1 named]# vi /etc/resolv.conf

search alphabd.net

nameserver 210.207.201.1

Step-9:    Check the named.conf & zone file by following this commands,

[root@ns1 ~]# named-checkconf  /var/named/chroot/etc/named.conf 

[root@ns1 ~]# named-checkzone  alphabd.net  /var/named/chroot/var/named/

alphabd.fz

[root@ns1 ~]# named-checkzone  alphabd.net   /var/named/chroot/var/named/

alphabd.rz

Step-10: DNS check

[root@ns1 ~]# service iptables stop

[root@ns1 ~]# service network restart

[root@ns1 ~]# chkconfig named on

[root@ns1 ~]# service named restart/status/start/stop/configtest

[root@ns1 ~]# host 210.207.201.1

[root@ns1 ~]# host ns1.alphabd.net

[root@ns1 ~]# Ping ns1.alphabd.net

[root@ns1 ~]# nslookup ns1.alphabd.net

[root@ns1 ~]# nslookup 210.207.201.1

[root@ns1 ~]# dig ns1.alphabd.net

[root@ns1 ~]# dig –x 210.207.201.1

[root@ns1 ~]# dig –x ns1.alphabd.net

[root@ns1 ~]# dig –t SOA alphabd.net

[root@ns1 ~]# dig –t axfr alphabd.net
