Install menggunakan perintah 

sudo apt-get install libpcre3 libpcre3-dev libpcrecpp0 libpcap0.8 libpcap0.8-dev \
mysql-server libmysqlclient15-dev libphp-adodb libgd2-xpm libgd2-xpm-dev php5-mysql \
php5-gd php-pear apache2 php5 php5-xmlrpc php5-mysql php5-gd php5-cli php5-curl \
mysql-client libdumbnet1 libdumbnet-dev php-pear

pear install Numbers_Roman-1.0.2
pear install Numbers_Words-0.16.2
pear install Image_Canvas-0.3.2
pear install Image_Graph-0.7.2
pear install --alldeps mail

Konfigurasi database 

mysql -u root -p123456

create database snort;
grant ALL on root.* to snort@localhost;
grant ALL on snort.* to snort@localhost IDENTIFIED BY 'snort' ;
grant ALL on snort.* to snort IDENTIFIED BY 'snort' ;
exit

Instal SNORT 

apt-get install snort-mysql snort-rules-default acidbase

Masukan 

Address range for the local network:  192.168.0.0/16
mysql password : snort

Konfigurasi database 

cd /usr/share/doc/snort-mysql/                                             
zcat create_mysql.gz | mysql -u <user> -h <host> -p <databasename>

Jika sedang belajar 

cd /usr/share/doc/snort-mysql/                                             
zcat create_mysql.gz | mysql -u root -h localhost -p123456 snort

Konfigurasi SNORT 

vi /etc/snort/database.conf

output database: alert, mysql, user=snort password=snort dbname=snort host=localhost
output database: log, mysql, user=snort password=snort dbname=snort host=localhost

Cek juga snort.conf harusnya OK 

vi /etc/snort/snort.conf

# dibagian output database masukan
include database.conf


Buang db-pending-config 

rm /etc/snort/db-pending-config

jika di perlukan 

dpkg-reconfigure -plow snort-mysql


Konfigurasi BASE 

vi /etc/acidbase/database.php 

$alert_user='snort';
$alert_password='snort';
$basepath='/acidbase';
$alert_dbname='snort';
$alert_host='localhost';
$alert_port=;
$DBtype='mysql';

Restart APACHE dan SNORT

/etc/init.d/apache2 restart
/etc/init.d/snort restart

Tampaknya snort bisa di jalankan menggunakan perintah 

/usr/sbin/snort -m 027 -D -d -l /var/log/snort -u snort -g snort -c /etc/snort/snort.conf -S HOME_NET=[192.168.0.0/16] -i eth0

Akses ke 

http://localhost/acidbase


Beberapa ERROR

Pada masa lalu kita menjalankan snort menggunakan 

snort -dev -c /etc/snort/snort.conf -D

jika terjadi fatal error seperti 

ERROR: Failed to initialize dynamic preprocessor: SF_SMTP version 1.1.8

Sebaiknya jalankan snort menggunakan perintah 

/etc/init.d/snort restart

Perbaiki Rules

Jalankan 

snort -dev -c /etc/snort/snort.conf

Akan keluar error seperti 

Warning: /etc/snort/rules/dos.rules(42) => threshold (in rule) is deprecated; use detection_filter instead.
ERROR: /etc/snort/rules/community-smtp.rules(13) => !any is not allowed
Fatal Error, Quitting..

Perbaiki line yang error misalnya 

vi /etc/snort/rules/dos.rules

delete line 42


Ijin Akses Non Localhost

Pada saat belajar, agar mesin non-localhost dapat mengakses kita perlu mengedit 

vi /etc/acidbase/apache.conf

Tambahkan 

<DirectoryMatch /usr/share/acidbase/>
  ...
  allow from 127.0.0.0/255.0.0.0
  allow from 0.0.0.0/0.0.0.0
  ...
</DirectoryMatch>

Restart Web Server 

/etc/init.d/apache2 restart
