Membuat Proxy Dengan Squid3 (debian)

Fungsi:
1.Menyimpan cache tampilan halaman web
2.Mengatur bandwidth internet ke client
3.Mengontrol aktivitas client (misalnya hak akses situs tertentu, melihat situs-situs yang dikunjungi client).

Bahan Membuat proxy:
1.Komputer minimal 2 lan card.
2.Komputer client
3.Sambungan internet

Langkah-langkah membuat proxy:
1.Setting ip server
#vim /etc/network/interfaces
iface eth0 inet static
address 192.168.2.35
netmask 255.255.255.192
network 192.168.2.0
broadcast 192.168.2.63
gateway 192.168.2.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 202.134.0.155
dns-search smkn1-tuban.sch.id
esc:wq
/etc/init.d/networking restart ->>merestrat lan card

2.install packet squid3
#apt-get install squid3

3.membuat partisi squid
#squid3 -z

4.Melakukan konfigurasi squid
Perhatian: untuk keamanan sebelum dilakukan konfigurasi sebaiknya file configurasi asli squid
disimpan dulu.
#cp /etc/squid3/squid.conf /etc/squid3/squid.conf_asli
#vim /etc/squid3/squid.conf
acl our_networks src 192.168.1.0/28 192.168.2.0/25 172.16.2.0/24
http_access allow our_networks
http_access allow localhost

#untuk melakukan blokir
acl backlist url_regex -i "/usr/share/backlist"
http_access deny backlist

esc:wq

5.Merestart squid
#/etc/init.d/squid3 restart

6.Setting client
