Konfigurasi DNS di Ubuntu 7.10 Menggunakan bind9

November 23rd, 2008 3 comments

Akhirnya berhasil juga setting DNS di Ubuntu Gutsy, walaupun harus bolak balik warnet dikarenakan saya nggak punya repositorinya. Kebetulan server inherent masih dalam proses perbaikan, makanya nggak bisa apt-get dari repositori lokal. Repot juga kalau nggak punya repositori, harus cari file-file dependensi yang dibutuhkan. Berikut yang dapat saya dokumentasikan.

Langkah-langkah setting DNS menggunakan bind9

1. Install bind9

root@komputer16-desktop:/home/komputer16/bind9# dpkg -i bind9_9.4.1-P1-3ubuntu2_i386.deb 
Selecting previously deselected package bind9.
(Reading database ... 89207 files and directories currently installed.)
Unpacking bind9 (from bind9_9.4.1-P1-3ubuntu2_i386.deb) ...
dpkg: dependency problems prevent configuration of bind9:
 bind9 depends on libdns32 (= 1:9.4.1-P1-3ubuntu2); however:
  Version of libdns32 on system is 1:9.4.1-P1-3.
 bind9 depends on libisccfg30 (= 1:9.4.1-P1-3ubuntu2); however:
  Version of libisccfg30 on system is 1:9.4.1-P1-3.
 bind9 depends on libisc32 (= 1:9.4.1-P1-3ubuntu2); however:
  Version of libisc32 on system is 1:9.4.1-P1-3.
 bind9 depends on libisccc30 (= 1:9.4.1-P1-3ubuntu2); however:
  Version of libisccc30 on system is 1:9.4.1-P1-3.
dpkg: error processing bind9 (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 bind9

Ternyata masih memerlukan file dependensi : libdns32, libisccfg30, libisc32, libisccc30. Cari di internet, download. Pastikan file dependensi tersebut untuk Ubuntu Gutsy Gibbon. Install file dependensi tersebut.

root@komputer16-desktop:/home/komputer16/bind9# dpkg -i libdns32_9.4.1-P1-3ubuntu2_i386.deb; dpkg -i libisccfg30_9.4.1-P1-3ubuntu2_i386.deb; dpkg -i libisc32_9.4.1-P1-3ubuntu2_i386.deb; dpkg -i libisccc30_9.4.1-P1-3ubuntu2_i386.deb

Proses installasi file dependensi selesai. Coba install lagi bind9

root@komputer16-desktop:/home/komputer16/bind9# dpkg -i bind9_9.4.1-P1-3ubuntu2_i386.deb

bind9 sudah diinstall.

Sudah terinstall. Kalau Anda punya repositorinya, bisa langsung pakai apt-get.

root@komputer16-desktop:/home/komputer16/bind9# apt-get install bind9

2. Pastikan bind9 sudah terinstall. Coba cek. Cuma untuk memastikan.

root@komputer16-desktop:/home/komputer16/bind9# dpkg -l | grep bind9
ii  bind9                                      1:9.4.1-P1-3ubuntu2           Internet Domain Name Server
ii  bind9-host                                 1:9.4.1-P1-3                  Version of 'host' bundled with BIND 9.X
ii  libbind9-30                                1:9.4.1-P1-3                  BIND9 Shared Library used by BIND

3. Edit file /etc/resolv.conf

root@komputer16-desktop:/home/komputer16/bind9# pico /etc/resolv.conf
domain enambelas.com
search enambelas.com
nameserver 192.168.1.16

4. Edit file /etc/bind/named.conf

root@komputer16-desktop:/home/komputer16/bind9# pico /etc/bind/named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include "/etc/bind/named.conf.options";

// 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

zone "localhost" {
        type master;
        file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
        type master;
        file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
	type master;
        file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
        type master;
        file "/etc/bind/db.255";
};

//tambahkan baris berikut
zone "enambelas.com" {
        type master;
        file "/etc/bind/db.enambelas.com";
};

zone "1.168.192.in-addr.arpa" {
	type master;
        file "/etc/bind/db.192.168.1";
};

// zone "com" { type delegation-only; };
// zone "net" { type delegation-only; };

// From the release notes:
//  Because many of our users are uncomfortable receiving undelegated answers
//  from root or top level domains, other than a few for whom that behaviour
//  has been trusted and expected for quite some length of time, we have now
//  introduced the "root-delegations-only" feature which applies delegation-only
//  logic to all top level domains, and to the root domain.  An exception list
//  should be specified, including "MUSEUM" and "DE", and any other top level
//  domains from whom undelegated responses are expected and trusted.
include "/etc/bind/named.conf.local";

5. Buat file /etc/bind/db.enambelas.com

root@komputer16-desktop:/home/komputer16/bind9# pico /etc/bind/db.enambelas.com
$TTL    86400

@       IN      SOA     enambelas.com.  root.enambelas.com.   (
                        20081122        ;Serial
                        604800          ;Refresh
                        86400           ;Retry
                        2419200         ;Expire
                        604800 )        ; Negative Cache TTL

@       IN      NS      enambelas.com.
@       IN      A       192.168.1.16

6. Buat file /etc/bind/db.192.168.1

root@komputer16-desktop:/home/komputer16/bind9# pico /etc/bind/db.192.168.1
$TTL    86400

@       IN      SOA     enambelas.com.  root.enambelas.com.   (
                        20081122        ;Serial
                        604800          ;Refresh
                        86400           ;Retry
                        2419200         ;Expire
                        604800)         ; Negative Cache TTL
;
        IN      NS      enambelas.com.
        IN      PTR     www.enambelas.com.

7. Cek apakah settingan file db.enambelas.com sudah benar?

root@komputer16-desktop:/home# named-checkzone enambelas.com /etc/bind/db.enambelas.com
zone enambelas.com/IN: loaded serial 20081122
OK

8. Cek apakah settingan file db.192.168.1 sudah benar?

root@komputer16-desktop:/home# named-checkzone 192.168.1 /etc/bind/db.192.168.1
zone 192.168.1/IN: loaded serial 20081122
OK

9. Restart service DNS

root@komputer16-desktop:/home/komputer16/bind9# /etc/init.d/bind9 restart
 * Stopping domain name service... bind                                                                                                              [ OK ]
 * Starting domain name service... bind                                                                                                              [ OK ]
 

10. Sudah selesai, sekarang tes dengan perintah dig atau ping

root@komputer16-desktop:/home/komputer16/bind9# dig enambelas.com
