Linux dns

DNS are the servers that translate domain names to IP addresses.

Setup - Ubuntu

It seems the default application for DNS is bind or bind9.

Install it:

 sudo apt-get intstall bind9

Stop/Start/Restart

 sudo services bind9 restart

Setup your own naming

You need to create a zone file. This tells the DNS what to do.

1. Create the initialize of the zone file.

 sudo vi named.conf.local

2. Add your own full qualified name to the file.

the zone is the name, file points to the config file for this name.

 zone "example.com" {
      type master;
      file "/etc/bind/db.example.com";
 }

3. Create the config file.

Create the config file by using the empty scaffolding file bind gives you.

 sudo cp db.empty db.example.com

4. Edit the new file

 ;
 ; BIND data file for local loopback interface
 ;
 $TTL     604800
 @        IN      SOA      example.com.    root.example.com.   (
                                 5            ; Serial
                            604800            ; Refresh
                             86400            ; Retry
                           2419200            ; Expire
                            604800 )          ; Negative Cache TTL
 ;
           IN     A        192.168.1.1
 @         IN     NS       localhost.
 www       IN     CNAME    example.com.
