Installation af DNS

Instructions

Install DNS sserver software

sudo apt-get install bind9

configure DNS (Bind)

We need to touch 5 files.

We will edit 3 files.

  1. /etc/bind/named.conf.local
  2. /etc/bind/named.conf.options
  3. /etc/resolv.conf

We will create 2 files.

  1. /etc/bind/zones/mydomain.com.db
  2. /etc/bind/zones/rev.0.168.192.in-addr.arpa

First step: add domain zone – mydomain.com

  • sudo vi /etc/bind/named.conf.local
# Our domain zone
zone "mydomain.com" {
   type master;
   file "/etc/bind/zones/mydomain.com.db";
}
 
# For reverse DNS 
zone "0.168.192.in-addr.arpa" {
   type master;
   file "/etc/bind/zones/rev.0.168.192.in-addr.arpa";
}

Secund step: Add the DNS servers from your ISP

  1. Sudo vi /etc/bind/named.conf.options
Forwarders {
 x.x.x.x
};

===Third step: Modify the resolv.conf file

$ Sudo vi /etc/resolve.conf 

search dka.dk.
nameserver 10.0.0.1

Fourth step: Define zones

Sudo mkdir /etc/bind/zones Sudo vi /etc/bind/zones/dka.dk.db 

$TTL 3D
@ IN SOA ns.mydomain.com. admin.mydomain.com. (
   2007062001
   28800
   3600
   604800
   38400
);
mydomain.com.  IN      NS         ns.mydomain.com.
ubuntudesktop  IN      A          192.168.0.10
www            IN      CNAME      ubuntudesktop
pc             IN      A          192.168.0.11
gw             IN      A          192.168.0.1
                       TXT        "Network Gateway"



The TTL or time to live is set for 3 days The ns.mydomain.com nameserver is defined ubuntudesktop, pc and gateway are entered as an A record An alias of www is assigned to ubuntudesktop using CNAME

Step five: Create a “rev.0.168.192.in-addr.arpa” file for reverse lookup

Sudo vi /tec/bind/zones/rev.0.168.192.in-addr.arpa 

$TTL 3D
@       IN      SOA     ns.mydomain.com. admin.mydomain.com. (
                2007062001
                28800
                604800
                604800
                86400
)
        IN      NS      ns.mydomain.com.
1       IN      PTR     gw.mydomain.com.
10      IN      PTR     ubuntudesktop.mydomain.com.
11      IN      PTR     pc.mydomain.com.
