< Back to the Title Topic

Create Zone files

Create forward and reverse zone files which we mentioned in the ‘/etc/named.conf’ file.

Step 1 – Create Forward Zone

Create forward.unixmen file in the ‘/var/named’ directory.

vi /var/named/forward.unixmen

Add the following lines:

$TTL 86400
@   IN  SOA     masterdns.unixmen.local. root.unixmen.local. (
        2011071001  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
@       IN  NS          masterdns.unixmen.local.
@       IN  NS          secondarydns.unixmen.local.
@       IN  A           192.168.1.101
@       IN  A           192.168.1.102
@       IN  A           192.168.1.103
masterdns       IN  A   192.168.1.101
secondarydns    IN  A   192.168.1.102
client          IN  A   192.168.1.103

Step 2 – Create Reverse Zone

Create reverse.unixmen file in the ‘/var/named’ directory.

vi /var/named/reverse.unixmen

Add the following lines:

 
 
$TTL 86400
@   IN  SOA     masterdns.unixmen.local. root.unixmen.local. (
        2011071001  ;Serial
        3600        ;Refresh
        1800        ;Retry
        604800      ;Expire
        86400       ;Minimum TTL
)
@       IN  NS          masterdns.unixmen.local.
@       IN  NS          secondarydns.unixmen.local.
@       IN  PTR         unixmen.local.
masterdns       IN  A   192.168.1.101
secondarydns    IN  A   192.168.1.102
client          IN  A   192.168.1.103
101     IN  PTR         masterdns.unixmen.local.
102     IN  PTR         secondarydns.unixmen.local.
103     IN  PTR         client.unixmen.local.
