#1--------Before you type any other code, first you need to log on as SU:
fm@fm-vm:~$ sudo su
[sudo] password for fm:
#2--------After that update your system by typing this:
root@fm-vm:/home/fm# apt-get update
#3--------Ubuntu will check & install for updates, after finished updating then install apache2:
root@fm-vm:/home/fm# apt-get install apache2
#4--------After that install bind9:
root@fm-vm:/home/fm# apt-get install bind9
#5--------After installing bind9, now configure the ip address:
root@fm-vm:/home/fm# nano /etc/network/interfaces
#---------We will create 3 IP Address. In the nano, write down this code:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.100.1
netmask 255.255.255.0
gateway 192.168.100.1
network 192.168.100.0

#---------When finished modifying, hit CTRL+X, than hit Y, then hit ENTER
#6--------After that then restart the neworking, use this command:
root@fm-vm:/home/fm# sudo ifdown eth0 && sudo ifup eth0
root@fm-vm:/home/fm# sudo ifdown eth0:1 && sudo ifup eth0:1
root@fm-vm:/home/fm# sudo ifdown eth0:2 && sudo ifup eth0:2
#7------Or use this:
root@fm-vm:/home/fm# sudo service network-manager restart
#-------Now try to ping the 3 IP’s, you have to make sure all of it REPLAY.
#-------If one of them not replay then check your configuration.
#-------If your configuration was right, then restart your Ubuntu.
#8------After doing command above, configure the host file by typing:
root@fm-vm:/home/fm# nano /etc/hosts
#-------Write down this 3 lines script right under 127.0.1.1:
192.168.100.1 farihin.com
192.168.100.2 forum.farihin.com
192.168.100.3 mail.farihin.com
#9------Now go to “/etc/bind” directories and list the files, make sure you have named.conf.local file:
root@fm-vm:/home/fm# cd /etc/bind
root@fm-vm:/etc/bind# ls
bind.keys db.empty named.conf.default-zones zones.rfc1918
db.0 db.local named.conf.local
db.127 db.root named.conf.options
#10------We need to modify named.conf.local files, so open it with nano:
root@fm-vm:/etc/bind# nano named.conf.local
#---------Our goal is to create 3 zone for “farihin.com”, “forum.farihin.com”, and “mail.farihin.com”. On nano write this script:
//
// Do any local configuration here
//
// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "farihin.com" {
type master;
file "/etc/bind/db.farihin";
};
zone "forum.farihin.com" {
type master;
file "/etc/bind/db.forumfarihin";
};
zone "mail.farihin.com" {
type master;
file "/etc/bind/db.mailfarihin";
};
zone "100.168.192.in-addr.arpa" {
type master;
file "/etc/bind/db.farihin.rev";
};
#--------When finished, hit CTRL+X, than hit Y, then hit ENTER
#11-----In this stage we will create a db files that we declare on our zone. First let’s create db.farihin file. Now copy the “db.local” file to “db.yourname” file:
root@fm-vm:/etc/bind# cp db.local db.farihin
#--------Then open the “db.yourname” file with nano:
root@fm-vm:/etc/bind# nano db.farihin
#--------On nano write this script:
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA farihin.com. root.farihin.com. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS farihin.com.
@ IN A 192.168.100.1
farihin.com IN A 192.168.100.1
forum.farihin.com IN A 192.168.100.2
mail.farihin.com IN A 192.168.100.3
#12------Second we’ll create db.farihin.rev file. Now copy “db.yourname” to “db.yourname.rev”, and open it with nano:
root@fm-vm:/etc/bind# cp db.farihin db.farihin.rev
root@fm-vm:/etc/bind# nano db.farihin.rev
#--------On nano write this script:
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA farihin.com. root.farihin.com. (
2 ; Serial
604800 ; Refresh

100.168.192.in-addr.arpa. IN NS farihin.com.
1 IN PTR farihin.com.
2 IN PTR forum.farihin.com.
3 IN PTR mail.farihin.com.
#13-------Third, we’ll create db.forumfarihin and db.mailfarihin by copying and modifying from db.farihin’s file:
root@fm-vm:/etc/bind# cp db.farihin db.forumfarihin
root@fm-vm:/etc/bind# nano db.forumfarihin
#----------Change line 5 (SOA), line 12 (NS), line 13 (A)
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA forum.farihin.com. root.farihin.com. (

mail.farihin.com IN A 192.168.100.3
--------------------------------------------------------------------------------------------------------------------
root@fm-vm:/etc/bind# cp db.farihin db.mailfarihin
root@fm-vm:/etc/bind# nano db.mailfarihin

#14-----Now configure the “resolv.conf” file by opening it with nano:
root@fm-vm:/etc/bind# nano /etc/resolv.conf
#--------On nano write this script:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
domain farihin.com
search farihin.com
nameserver 192.168.100.1
#15--------Now restart the bind9:
root@fm-vm:/etc/bind# /etc/init.d/bind9 restart
#16--------After restarting, try to ping the domain and sub-domain:
root@fm-vm:/etc/bind# ping farihin.com
PING farihin.com (192.168.100.1) 56(84) bytes of data.
64 bytes from farihin.com (192.168.100.1): icmp_seq=1 ttl=64 time=0.014 ms
root@fm-vm:/etc/bind# ping forum.farihin.com
PING forum.farihin.com (192.168.100.2) 56(84) bytes of data.
64 bytes from forum.farihin.com (192.168.100.2): icmp_seq=1 ttl=64 time=0.015 ms
root@fm-vm:/etc/bind# ping mail.farihin.com

64 bytes from mail.farihin.com (192.168.100.3): icmp_seq=1 ttl=64 time=0.014 ms
#17--------And the last do the nslookup:
root@fm-vm:/etc/bind# nslookup farihin.com
Server: 192.168.100.1
Address: 192.168.100.1#53
Name: farihin.com
Address: 192.168.100.1
#--You now finished configuring DNS Server.
#--If there is REPLAY when you doing ping then your configuration was right, if it’s not then re-check your configuration. And if nslookup give a result you’re 100% DONE.
#--Another way to test the DNS Server go to your web browser and type farihin.com OR mail.farihin.com OR forum.farihin.com on the addressbar.
