DNS Server Configuration

Below steps were executed on real server. I have mentioned only the important commands/entries required to setup DNS server. In this scenario, there is only 1 client is configured to test the setup. 

[root@server etc]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=server.example.com


[root@server etc]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.10 server.example.com server
192.168.0.12 client1.example.com client1

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


#cat named.conf
options {
        listen-on port 53 { 127.0.0.1; 192.168.0.10;};
        #listen-on-v6 port 53 { ::1; };


allow-query     { any;};


include "/etc/named.rfc1912.zones";
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

#cat /etc/named.rfc1912.zones

zone "example.com" IN {
        type master;
        file "forward.zone";
        allow-update { none; };
};

zone "0.168.192.in-addr.arpa" IN {
        type master;
        file "reverse.zone";
        allow-update { none; };

};
