Instalasi DansGuardian

Install SSH, Squid cache & DansGuardian

# apt-get install openssh-server squid dansguardian

Konfigurasi DansGuardian

# vi /etc/dansguardian/dansguardian.conf 

Lakukan

• Jika IP address Server adalah, 192.168.0.1. Ubah

accessdeniedaddress = 'http://YOURSERVER.YOURDOMAIN/cgi-bin/dansguardian.pl'

menjadi

accessdeniedaddress = 'http://192.168.0.1/cgi-bin/dansguardian.pl'

• Buang / comment kalimat "UNCONFIGURED - Please remove this line after configuration" setelah semua proses konfigurasi selesai.
• Ubah variabel 'virusscan' menjadi off, jika anda belum menyiapkan clamav untuk DansGuardian. Biasanya di Ubuntu clamav akan terinstall bersama DansGuardian.

Siapkan port ke Firewall. Bagian ini memang sifatnya optional, tapi sangat di sarankan. Copy perintah berikut ke file /etc/network/if-up.d/iptables-config

#!/bin/bash
iptables -F
# set the default policy for each of the pre-defined chains
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD DROP
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
# to allow incoming SSH and Proxy
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -m state --state NEW -p tcp -m tcp -s 127.0.0.1 --dport 3128 -j ACCEPT
iptables -A INPUT -m state --state NEW -p tcp -m tcp --dport 8080 -j ACCEPT
# drop everything else
iptables -A INPUT -i eth+ -p udp -j DROP
iptables -A INPUT -i eth+ -p tcp -m tcp --syn -j DROP

Pastikan iptables-config dapat di execute / jalankan

# chmod +x /etc/network/if-up.d/iptables-config

Aktifkan SSH, DansGuardian, & Squid cache saat startup

# update-rc.d ssh defaults 
# update-rc.d squid defaults 
# update-rc.d dansguardian defaults 

Restart

# /etc/init.d/networking restart
# /etc/init.d/squid restart
# /etc/init.d/dansguardian restart
