Pastikan nama domain yang dikehendaki belum terdaftar di internet, untuk mengetahui nama domain tersebut sudah terdaftar atau belum bisa menggunakan bantuan dari website whois.net. Dalam kasus ini saya akan menggunakan nama domain “gudanghiburan.net”

Memeriksa nama domain tersebut sudah terdaftar atau belum dapat dilakukan dengan mengisi pada bagian “WHOIS Lookup“, dan hasil untuk nama domain “gudanghiburan.net” adalah “Domain name is not currently registered. Available for you now!“. Sip nama domain tersebut belum terdaftar. Lanjut ke konfigurasi Bind9.

Membuat Zone :
[root@proxy-xnet ~]# cd /etc/namedb
[root@proxy-xnet /etc/namedb]# nano named.conf
tambahkan baris dibawah ini :

//gudanghiburan.net
zone “gudanghiburan.net” {
type master;
file “/etc/namedb/master/gudanghiburan.net.db”;
};

zone “0.168.192.in-addr.arpa” {
type master;
file “/etc/namedb/master/192.168.0.db”;
};

Simpan kembali named.conf

Selanjutnya buat file Zone yaitu “gudanghiburan.net.db” dan “192.168.0.db” di dalam direktori “master”
[root@proxy-xnet /etc/namedb]# cd /master
[root@proxy-xnet /etc/namedb/master]#
[root@proxy-xnet /etc/namedb/master]# nano gudanghiburan.net.db
yang berisi :
$TTL 86400
@ IN SOA gudanghiburan.net. root.gudanghiburan.net. (
20081122 ;Serial
604800 ;Refresh
86400 ;Retry
2419200 ;Expire
604800 ) ; Negative Cache TTL
;
@ IN NS gudanghiburan.net.
@ IN A 192.168.0.101

[root@proxy-xnet /etc/namedb/master]# nano 192.168.0.db
yang berisi :
$TTL 86400
@ IN SOA gudanghiburan.net. root.gudanghiburan.net. (
20081122 ;Serial
604800 ;Refresh
86400 ;Retry
2419200 ;Expire
604800) ; Negative Cache TTL
;
IN NS gudanghiburan.net.
IN PTR www.gudanghiburan.net.

Selanjutnya cek konfigurasi :
[root@proxy-xnet /etc/namedb/master]# named-checkzone gudanghiburan.net /etc/nameedb/master/gudanghiburan.net.db
zone gudanghiburan.net/IN: loaded serial 20081122
OK

Restrat Bind9
[root@proxy-xnet /etc/namedb/master]# /etc/rc.d/named restart

Tes Konfigurasi :
[root@proxy-xnet /etc/namedb/master]# dig gudanghiburan.net

****  To setup dhcpd, you may have to copy /usr/local/etc/dhcpd.conf.sample
to /usr/local/etc/dhcpd.conf for editing.

Tambahkan di rc.conf :
[root@arema /home/arema]# nano /etc/rc.conf
dhcpd_enable=”YES”
dhcpd_ifaces=”xl0″

restart mesin……

lihat client yang aktif :
[root@arema /home/arema]# tail -f /var/db/dhcpd/dhcpd.leases

contoh hasilnya :

dah siap? yuk kita mulai

pertama pastikan anda talah mempunyai squid box, dan sudah running. sebab kalo mati sama.
pertama buat daftar situs yang mau di block, supaya lebih mudah nya ambil di sini
ftp://ftp.univ-tlse1.fr/pub/reseau/cache/squidguard_contrib/adult.tar.gz
kemudian di ekstrak jadikan txt, selanjutnya di simpan dalam squid box
parno.txt <<< nama file
/etc/squid <<< lokasi file. terserah mau ditaruh di mana sesuka anda

setting di squid
acl parno dstdomain “/etc/squid/parno.txt” <<< tambahkan acl-nya
http_access deny parno <<< tambahkan di bagian http_access paling atas. (ingat ditambahkan pada squid.conf)

nah sekarang tinggal restart squid nya dan coba akses salah satu alamat yang ada dalam file tadi.

biar lebih manis tambahkan skrip redirect
buka file ERR_ACCESS_DENIED
biasa nya terdapat pada /usr/local/squid/share/errors/English tambahkan kode dibawah ini :
<meta HTTP-EQUIV=”REFRESH” content=”0; url=http://www.google.com”>

dah siap sekarang restrat lagi biar mantab.

agar tidak lupa :

1. vote files = ekstensi file yang diblacklist
2. user name disesuaikan dengan user computer, bukan computer name
3. main level adalah root direktori, dimana semua direktori user terdapat di dalamnya
4. data user digunakan untuk akses read ke semua data user
5. kurang jelas baca manual http://us1.samba.org/samba/
