Latihan DNS Server

DNS Server

Virtual Box 

PC Virtual =debianServer01
adapter1 -> host Only
adapter2 -> NAT

konfigurasi DASAR

a. Konfigurasi Interface
   
   root@debian:~# nano /etc/network/interfaces
 
   konfigurasi sebagai berikut 

   #Primary network interface
    auto eth0
    iface eth0 inet static
 address 192.168.200.1
 netmask 255.255.255.0


   #Secondary network interface
    auto eth1
    iface eth1 inet dhcp


   restart fungsi networking -> /etc/init.d/networking restart

   konfigurasi PC HOST agar dapat berkomunikasi dng PC Virtual melalui "VirtualBox Host-Only Adapter"

b. mengganti HOSTNAME
   root@debian:~# nano /etc/hostname
   
   smk00

c. mengganti informasi pada /etc/hosts

   root@debian:~# nano /etc/hosts



Konfigurasi DNS Server - BIND9
Fungsi DNS Server ? menerjemahkan alamat nama domain ke alamat IP Address.

1. File Record  ? daftar nama2 domain yg dicatat pada DNS Server "/etc/bind/named.conf.local"
2. File Forward ? daftar terjemahan nama domain ke alamat IP address contoh = "/etc/bind/db.local"
3. File Reverse ? daftar terjemahan alamat IP address suatu domain   contoh = "/etc/bind/db.127"
4. File Resolve ? daftar IP DNS Server lainnya selain IP DNS Server lokal.
                  (jika lokal DNS Server tdk kenal, maka akan ditanyakan ke DNS Server lainnya)




Instal Bind9

root@smk:~#apt-get install bind9

file record
konfigurasi File record
root@smk:~#cd /etc/bind9
root@smk:/etc/bind~# nano named.conf.local

   zone "smk.net" {
        type master;
        file "db.smk";
        };

   zone "168.192.in-addr.arpa" {
        type master;
        file "db.192";
        };


file forward&reverse
duplikat file forward dan reverse milik localhost

root@smk:/etc/bind~#cp db.local /var/cache/bind/db.smk
root@smk:/etc/bind~#cp db.127 /var/cache/bind/db.192

edit file Forward
root@smk:/etc/bind~#cd /var/cache/bind
root@smk:/var/cache/bind~#nano db.smk

  ;
  ; BIND data file for local loopback interface
  ;
  $TTL    604800
  @       IN      SOA     smk.net. root.smk.net. (
                                  2         ; Serial
                             604800         ; Refresh
                              86400         ; Retry
                            2419200         ; Expire
                             604800 )       ; Negative Cache TTL
  ;
  @       IN      NS      smk.net.
  @       IN      A       192.168.200.1
  ns      IN      A       192.168.200.1
  @       IN      AAAA    ::1



edit file reverse
root@smk:/var/cache/bind~#nano db.192


  ;
  ; BIND reverse data file for local loopback interface
  ;
  $TTL    604800
  @       IN      SOA     smk.net. root.smk.net. (
                                1         ; Serial
                           604800         ; Refresh
                            86400         ; Retry
                          2419200         ; Expire
                           604800 )       ; Negative Cache TTL
  ;
  @       IN      NS      smk.net.
  1.200   IN      PTR     smk.net.
  1.200   IN      PTR     smk.net.

file resolver
edit file resolver untuk meletakkan alamat IP DNS Lokal pada bagian atas file resolver
root@smk:/var/cache/bind~#nano /etc/resolv.conf

  nameserver 192.168.200.1  
  nameserver 172.20.1.1
  nameserver 208.67.222.222
  nameserver 202.134.1.10
  nameserver 202.134.2.5
  nameserver 8.8.8.8
  nameserver 8.8.4.4
  nameserver 192.168.200.1

restart fungsi DNS Server
root@smk:/var/cache/bind~#/etc/init.d/bind9 restart

Lakukan pengujian dengan nslookup
root@smk00:~# nslookup
> smk.net
Server:         192.168.200.1
Address:        192.168.200.1#53

Name:   smk.net
Address: 192.168.200.1
> 192.168.200.1
Server:         192.168.200.1
Address:        192.168.200.1#53

1.200.168.192.in-addr.arpa      name = smk.net.
