pear install Numbers_Roman
pear install Numbers_Words-0.18.1
pear install Image_Canvas-0.3.5
pear install Image_Graph-0.8.0
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 snort-common snort-common-libraries snort-rules-default

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
