Installation af DNS

Instruktioner

Installer DNS Server

sudo apt-get install bind9

configure DNS (Bind)

Vi skal bruge 5 filer.

We will edit 3 files.

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

We will create 2 files.

  1. /etc/bind/zones/dka.local.db
  2. /etc/bind/zones/rev.0.0.10.in-addr.arpa.db

First step: add domain zone – dka.local

  • sudo vi /etc/bind/named.conf.local
# Our Domain zone
zone "dka.local." {
        type master;
        file "/etc/bind/zones/dka.local.db";
};

# For reverse DNS
zone "0.0.10.in-addr.arpa" {
        type master;
        file "/etc/bind/zones/rev.0.0.10.in-addr.arpa.db";
};

Secund step: Add the DNS servers from your ISP

  1. Sudo vi /etc/bind/named.conf.options
        forwarders {
                172.16.4.66;
         };

        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
        listen-on { any; };

allow-query { 127.0.0.1; 172.16.4.66/24; 10.0.0.0/24;};
};

Third step: Modify the resolv.conf file

$ Sudo vi /etc/resolve.conf - Version 12.04 skal man ændre nano /etc/resolvconf/resolv.conf.d/base 

nameserver 10.0.0.1
domain dka.local
search dka.local

Fourth step: Define zones

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

; BIND data file for local loopback interface
;
$TTL    604800
@       IN      SOA     ns.dka.local. root.dka.local. (
                              8         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      ns.dka.local.
ns      IN      A       10.0.0.1
ubuntu  IN      A       10.0.0.21



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.0.0.10.in-addr.arpa” file for reverse lookup

Sudo nano /etc/bind/zones/rev.0.0.10.in-addr.arpa.db 

$TTL 3D
@       IN      SOA     ns.dka.local. admin.dka.local. (
                2007062001
                28800
                604800
                604800
                86400
)
        IN      NS      ns.dka.local.
2       IN      PTR     ubuntu.dka.local

Step seks: Test vores nye domæne og DNS entries

Dig 

$ dig dka.local

Nslookup 

nslookup ns
