Lima langkah mudah membuat Realtime DNS server untuk bisnis domain hosting dengan Mysql record sebagai zone record

Seringkali kita susah melakukan konfigurasi Name server bind dimana konfigurasinya adalah
file texts misalnya yang berada pada /var/named. Kasus lainnya adalah ketika melakukan perubahan pada record NS (misalnya pada sebuah environment DOmain Hosting) dimana reabilitas & realtime sangat perlu kita harus merestart DNS/nameserver kita, dan hal ini tentu saja membuat problem yang fatal misalnya saat kita melakukan restart DNS dan ketika itu ada query maka NDS tidak akan mereply query domain name, akibatnya error pointing domain atau alamat domain tidak diketahui.

DLZ (Dinamilcy Loadable Zone) merupakan solusi terbaik untuk saat ini untuk mengkonfigurasi sebuah nameserver dalam environtment domain hosting. Dengan menggunakan DLZ solusi baru didapat yaitu :

1. data NS record disimpan dalam database record (bukan test based)
2. perubahan terhadap record DNS dalam database mysql akan langsung diload oleh BIND tanpa perlu restart dns server.
3. pembuatan interface domain akan lebih mudah dicustomize sendiri karena hanya sebatas insert dan update record dalam database, sisanya akan dilakukan otomatis oleh BIND-DLZ

Untuk experiment ini saya memakai versi bind-9.4.1 dan dlz-patch versi DLZ-0.7 dan mysql versi 5.0.37 pada lingkungan zendwalk/zendcafe yang masih 1 jenis distro slackware dan kernel 2.6.21.3

Marilah langsung saja ke teknis instalasi:

##0.Download extrack source dari bind dan dlz misalnya ke home/compile, kemudian lakukan patch

mkdir /home/compile/
cd /home/compile/
wget http://ftp.isc.org/isc/bind/cur/9.4/bind-9.4.1.tar.gz
wget http://optusnet.dl.sourceforge.net/sourceforge/bind-dlz/DLZ-0.7.0.tar.gz
tar -xzf bind-9.4.1.tar.gz
cd bind-9.4.1
tar -xzf /home/compile/DLZ-0.7.0.tar.gz

##1. option compile bind
./configure --with-dlz-mysql=yes
make && make install

##2. tambahan untuk named.conf agar meload dlz
dlz "Mysql zone" {
     database "mysql
     {host=localhost dbname=dns user=dns pass=PasswordHere ssl=false port=3306 socket=/mysql/mysql.sock}
     {SELECT zone FROM resource_records WHERE zone = '%zone%'}
     {SELECT ttl, type, mx_priority, IF(type = 'TXT', CONCAT('\"',data,'\"'), data) AS data
      FROM resource_records
      WHERE zone = '%zone%' AND host = '%record%' AND type <> 'SOA' AND type <> 'NS'}
     {SELECT ttl, type, data, primary_ns, resp_contact, serial, refresh, retry, expire, minimum
      FROM resource_records
      WHERE zone = '%zone%' AND (type = 'SOA' OR type='NS')}
     {SELECT ttl, type, host, mx_priority, IF(type = 'TXT', CONCAT('\"',data,'\"'), data) AS data, resp_contact, serial, refresh, retry, expire, minimum
      FROM resource_records
      WHERE zone = '%zone%' AND type <> 'SOA' AND type <> 'NS'}";
};

###3. untuk memasukkan record 1 buah dns, nameserver ke mysql
mysql -u root -e "create database dns"
mysql -u root dns -e "
INSERT INTO dns.resource_records (   zone,
                        ttl,
                        type,
                        host,
                        primary_ns,
                        resp_contact,
                        serial,
                        refresh,
                        retry,
                        expire,
                        minimum ) VALUES (      'xmedia.com',
                                                86400,
                                                'SOA',
                                                '@',
                                                'ns1.xmedia.com.',
                                                'hostmaster.xmedia.com.',
                                                2007112201,
                                                10800,
                                                7200,
                                                604800,
                                                86400 );

INSERT INTO `resource_records` (`id`, `zone`, `ttl`, `type`, `host`, `mx_priority`, `data`, `primary_ns`, `resp_contact`, `serial`, `refresh`, `retry`, `expire`, `minimum`) VALUE (101, 'xmedia.com', 86400, 'NS', '@', NULL, 'ns1.xmedia.com.', NULL, NULL, NULL, NULL, NULL, NULL, NULL);
INSERT INTO `resource_records` (`id`, `zone`, `ttl`, `type`, `host`, `mx_priority`, `data`, `primary_ns`, `resp_contact`, `serial`, `refresh`, `retry`, `expire`, `minimum`) VALUE (102, 'xmedia.com', 86400, 'NS', '@', NULL, 'ns2.xmedia.com.', NULL, NULL, NULL, NULL, NULL, NULL, NULL);
INSERT INTO `resource_records` (`id`, `zone`, `ttl`, `type`, `host`, `mx_priority`, `data`, `primary_ns`, `resp_contact`, `serial`, `refresh`, `retry`, `expire`, `minimum`) VALUE (103, 'xmedia.com', 86400, 'MX', '@', 10, 'mail.xmedia.com.', NULL, NULL, NULL, NULL, NULL, NULL, NULL);
INSERT INTO `resource_records` (`id`, `zone`, `ttl`, `type`, `host`, `mx_priority`, `data`, `primary_ns`, `resp_contact`, `serial`, `refresh`, `retry`, `expire`, `minimum`) VALUE (104, 'xmedia.com', 86400, 'A', '@', NULL, '192.168.1.50', NULL, NULL, NULL, NULL, NULL, NULL, NULL);
INSERT INTO `resource_records` (`id`, `zone`, `ttl`, `type`, `host`, `mx_priority`, `data`, `primary_ns`, `resp_contact`, `serial`, `refresh`, `retry`, `expire`, `minimum`) VALUE (105, 'xmedia.com', 86400, 'A', 'www', NULL, '192.168.1.50', NULL, NULL, NULL, NULL, NULL, NULL, NULL);
"

###4. start dns dalam mode debug agar bisa dilihat errornya
killall named
named -c /var/named.conf -g

###testing nameserver , harusnya keluar jawaban alamat NS & IP dari host
dig soa xmedia.com @localhost
nslookup xmedia.com localhost

Install Freeradius Dialupadmin dan Mikrotik

Jun 29, '07 8:50 PM
for everyone

Last project for kampus sebelum hijrah yaitu menginstall freeradius untuk backend manajemen account user internet dan wifi hotspot serta dialupadmin untuk interface. Mikrotik digunakan sebagai server gateway semua pengguna. Untuk lebih praktisnya aku menggunakan debian linux (dalam hal ini aku pake aja kubuntu linux) dengan alasan efisiensi waktu, debian gampang banget cara nginstall dan nambain paketnya. nah caranya sbb:

1. install apache2 dan php5
bash#   apt-get install apache2 php5
( jalankan apache)
bash#   /etc/init.d/httpd start

2. install mysql & mysqlclient
bash#   apt-get install mysql mysql-client mysqlclient12-dev
bash#   /etc/init.d/mysqld start
bash#   mysql -u root

3. install freeradius & freeradius mysql
bash# apt-get install freeradius freeradius-mysql

4. download dialupadmin dari sourceforge dan extract di /usr/local
bash# cd /usr/local
bash# tar -xzf dialupadmin.xxx

5. pindah ke folder /var/www
bash# cd /var/www

6. buat simbolik link ke usr/local
bash# ln -s /usr/local/dialup_admin dialup_admin

7. setting folder dan file permision agar bisa execute
bash# chmod -R 755 dialup_admin
bash# chown apache.apache -R dialup_admin

8. setting account untuk freeradius
bash# cd /etc/freeradius
bash# vi users

tambahkan baris berikut dan simpan ( [ESC] + :wq )

"imam"    Auth-Type := Local, User-Password == "imam"

                 Reply-Message = "selamat datang %u"

                 Service-Type = Framed-User,

                 Framed-Routing = Broadcast-Listen,

                 Framed-Filter-Id = "20modun",

                 Fall-Through = Yes

9. setting clients.conf, tambahkan client untuk IP mikrotik

bash# vi /etc/freeradius/clients.conf

tambahkan baris berikut:

client 10.10.17.5 {
secret = rahasiadong
shortname = hotspot.unsoed.ac.id
}

ubah juga secret untuk 127.0.0.1 atau localhost (samin dengan secret code diatas) dan simpan.

10. testing radius (kalo bukan radiusd ya freeradius )

bash # radiusd -XXX -A

11. buka console yang laen dan testing login

bash # radtest imam imam localhost 0 rahasiadong

kalau berhasil harusnya muncul texts:
selamat datang imam

12. setting sql.conf

    server = "localhost"
        login = "root"
        password = ""

13. donload juga freeradius src
bash# apt-get source freeradius

14. buat database radius
bash# mysql -u root -e "create database radius"
bash# mysql -u root radius < /freeradius-0.5/src/modules/rlm_sql/drivers/rlm_sql_mysql/db_mysql.sql

kalo gak pake sql berikut:

create database if not exists radius;
use radius;

) ;

#

secret varchar(60) DEFAULT 'secret' NOT NULL,
community varchar(50),
description varchar(200) DEFAULT 'RADIUS Client',
PRIMARY KEY (id),

);

15. tambain user untuk radius

##contoh isian database

delete from radcheck;
INSERT INTO radcheck(UserName,Attribute,op,Value) VALUES
('user1','User-Password','==','password1'),
('user2','User-Password','==','password2');

delete from usergroup;
INSERT INTO usergroup(UserName, GroupName) VALUES
('user1', 'dynamic'),('user2', 'static');

INSERT INTO radreply(UserName, Attribute, op, value) VALUES
('user2', 'Cisco-Avpair',      ':=', 'throttle=yes'),
('user2', 'Framed-IP-Address', ':=', '10.10.16.80');

delete from radgroupreply;
INSERT INTO radgroupreply (GroupName, Attribute, op, Value) VALUES
                ('static', 'Cisco-Avpair',        ':=', 'throttle=no'),
                ('dynamic', 'Cisco-Avpair',       ':=', 'throttle=yes'),
                ('dynamic', 'Framed-Compression', ':=', 'Van-Jacobsen-TCP-IP'),
                ('dynamic', 'Framed-IP-Address', ':=', '255.255.255.254'),
                ('dynamic', 'Framed-MTU',         ':=', '1500'),
                ('dynamic', 'Framed-Protocol',    ':=', 'PPP'),
                ('dynamic', 'Framed-Route',       ':=', '10.10.16.80'),
                ('dynamic', 'Service-Type',       ':=', 'Framed-User');

16. setting radiusd.conf , aktifkan modul sql


authorize {
        sql
        files
        mschap
}

authenticate {
        mschap
}

accounting {
        unix
        sql
        radutmp
}


17. jalankan lagi radius mode debug
bash# killall radiusd
bash# radiusd -X -A


18. bersambung ke bagian 2 hehehee...panjang sekali sih 
males ngetiknya (contact 
iferianto@yahoo.com aja klo ada project ya. otre boz)
