Perlu diketahui bahwa paket DNS Server di Ubuntu bisa dipilih ketika pertama kali diinstall. Bisadiperiksa dengan mengetik :
sudo apt-cache policy bind9
contoh di sistem saya :
aspan@aspan-laptop:~$ sudo apt-cache policy bind9
[sudo] password for aspan:
bind9:
Installed: 1:9.7.0.dfsg.P1-1ubuntu0.1
Candidate: 1:9.7.0.dfsg.P1-1ubuntu0.1
Version table:
*** 1:9.7.0.dfsg.P1-1ubuntu0.1 0
100 /var/lib/dpkg/status
1:9.7.0.dfsg.P1-1 0
aspan@aspan-laptop:~$
Lihat baris Installed, berarti bind9 sudah terinstall di sistem saya.
Jika belum terinstall, lakukan install, update dulu ketik :
sudo apt-get update
lalu install ketik :
sudo nano apt-get install bind9
Setelah itu langsung saja disetting, masuk ke direktori bind untuk berkenalan dulu dengan file-file bind,
ketik :
cd /etc/bind/
ketik :
ls
contoh di sistem saya :
aspan@aspan-laptop:~$ cd /etc/bind
aspan@aspan-laptop:/etc/bind$ ls
bind.keys db.255 db.ip named.conf named.conf.options
db.0 db.coba db.local named.conf.default-zones rndc.key
db.127 db.empty db.root named.conf.local zones.rfc1918
aspan@aspan-laptop:/etc/bind$
perhatikan file yang bernama db.local. Copy file tersebut, ketik :
sudo cp db.local db.coba
tercipta sebuah file yang bernama db.coba, langsung saja diedit, ketik :
sudo nano db.coba
isinya kurang lebih seperti ini :
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA localhost. root.localhost. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
@ IN A 127.0.0.1
@ IN AAAA ::1
ubah menjadi seperti di bawah ini :
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.aspan.net. root.aspan.net. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
IN NS ns.aspan.net.
IN A 192.168.1.10
ns IN A 192.168.1.10
@ IN AAAA ::1
www IN CNAME ns
ftp IN CNAME ns
smtp IN CNAME ns
fulan IN CNAME ns
chat IN CNAME ns
Penjelasan :
No Asal Perubahan
localhost ns.aspan.net
root.localhost. ns.aspan.net
@ IN NS localhost. IN NS ns.aspan.net.
@ IN A 127.0.0.1 @ IN A 192.168.88.13
(tambahan) ns IN A 192.168.88.13
www IN CNAME ns
ftp IN CNAME ns
smtp IN CNAME ns
fulan IN CNAME ns
chat IN CNAME ns
copy file db.coba menjadi db.ip, ketik :
sudo cp db.coba db.ip
edit, ketik :
sudo nano db.ip
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.aspan.net. root.aspan.net. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.aspan.net.
13 IN PTR ns.aspan.net.
ns IN A 192.168.88.13
@ IN AAAA ::1
Penjelasan :
13 adalah host ID dari ip address DNS Server
kemudian edit file named.conf, ketik :
sudo nano named.conf
isinya kurang lebih seperti ini :
// prime the server with knowledge of the root servers
zone "." {
type hint;
file "/etc/bind/db.root";
};
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
;
$TTL 604800
@ IN SOA ns.aspan.net. root.aspan.net. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.aspan.net.
13 IN PTR ns.aspan.net.
ns IN A 192.168.88.13
@ IN AAAA ::1

zone "aspan.net" {
type master;
file "/etc/bind/db.coba";
};
zone "88.168.192.in-addr.arpa" {
type master;
file "/etc/bind/db.ip";
};
zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};
zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};
restart service bind9 ketik :
sudo /etc/init.d/bind9 restart
kemudian buat seluruh client menggunakan DNS yang telah kita buat. Jika di sistem Linux IP DNS
Server bisa kita masukan di file /etc/resolv.conf, ketik :
sudo nano /etc/resolv.conf
search aspan.net
nameserver 192.168.88.13
jika menggunakan network manager silakan lihat screenshot :
test domain dengan perintah :
dig -x aspan.net
; <<>> DiG 9.7.0-P1 <<>> -x aspan.net
