Setting DNS pada Ubuntu

Pada terminal, masukkan perintah berikut untuk menginstal dns:

$ sudo apt-get install bind9

Untuk pengujian dan troubleshooting masalah DNS adalah paket dnsutils. Untuk menginstal dnsutils masukkan berikut ini:

$ sudo apt-get install dnsutils

Edit /etc/bind/ named.conf.options : (tambahkan DNS IP ISP Anda)

$ sudo gedit /etc/bind/named.conf.options

directory “/var/cache/bind”;
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0′s placeholder.
// forwarders {
// 0.0.0.0;
// };
// Menambah IP DNS ISP Anda

forwarders {
202.155.0.10;
202.155.0.15;
};

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

Primary Master untuk domain wahcilik.com. Edit /etc/bind/named.conf.local:

$ sudo gedit /etc/bind/named.conf.local

//
// 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 “wahcilik.com” {
type master;
file “/etc/bind/db.wahcilik.com”;
};

Membuat file / etc / bind / db.wahcilik.com:

# sudo cp /etc/bind/db.local /etc/bind/db.wahcilik.com

Edit file /etc/bind/db.wahcilik.com

$ sudo gedit /etc/bind/db.wahcilik.com
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.wahcilik.com. root.wahcilik.com. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.wahcilik.com.
@ IN A 192.168.50.1
@ IN AAAA ::1
ns IN A 192.168.50.1
www IN A 192.168.50.1

Reverse Zone File
Edit /etc/bind/named.conf.local :

$ sudo gedit /etc/bind/named.conf.local
//
// 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 “wahcilik.com” {
type master;
file “/etc/bind/db.wahcilik.com”;
};

zone “50.168.192.in-addr.arpa” {
type master;
notify no;
file “/etc/bind/db.192″;
};

Sekarang buat file /etc/bind/db.192 :

$ sudo cp /etc/bind/db.127 /etc/bind/db.192

Edit /etc/bind/db.192 :

                    $ sudo gedit /etc/bind/db.192

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

restart BIND9:

$ sudo /etc/init.d/bind9 restart

Secondary Master
Untuk membuat DNS master dan Slave, contoh :
DNS Master IP Address 192.168.50.1
DNS Slave IP Address 192.168.50.111
Pada MASTER:
edit /etc/bind/named.conf.local:

zone “wahcilik.com” {
type master;
file “/etc/bind/db.wahcilik.com”;
allow-transfer { 192.168.50.111; };
};

zone “50.168.192.in-addr.arpa” {
type master;
notify no;
file “/etc/bind/db.192″;
allow-transfer { 192.168.50.111; };
};

Pada SLAVE :
Edit /etc/bind/named.conf.local :

zone “wahcilik.com” {
type slave;
file “db.wahcilik.com”;
masters { 192.168.50.1; };
};

zone “50.168.192.in-addr.arpa” {
type slave;
file “db.192″;
masters { 192.168.50.1; };
};

Restart BIND9

$ sudo /etc/init.d/bind9 restart

resolv.conf
edit /etc/resolv.conf :

                   $ sudo gedit /etc/resolv.conf

nameserver 192.168.50.1
nameserver 202.155.0.10
nameserver 202.155.0.15
