Download & Install Barnyard2
Barnyard2 akan memperbaiki efisiensi Snort dengan cara mengurangi beban dari engine deteksi utama. Barnyard2 akan membaca file keluaran logging snort dan memasukannya ke database. Jika database tidak tersedia, Barnyard2 akan memasukan data saat database kembali online sehingga tidak ada alert yang akan hilang.
Instalasi barnyard2,
cd /usr/local/src git clone http://github.com/firnsy/barnyard2.git barnyard2 cd barnyard2 autoreconf -fvi -I ./m4 ./configure -with-mysql -with-mysql-libraries=/usr/lib/x86_64-linux-gnu make make install cp etc/barnyard2.conf /usr/local/snort/etc mkdir /var/log/barnyard2 chmod 666 /var/log/barnyard2 touch /var/log/snort/barnyard2.waldo chown snort.snort /var/log/snort/barnyard2.waldo
Buat database untuk snort yang akan digunakan Barnyard untuk penyimpanan,
mysql –u root –p123456
create database snortdb; grant create, insert, select, delete, update on snortdb.* to snortuser@localhost identified by ‘3ngin33r'; flush privileges;
Buat Snort DB
mysql -u root -p -D snortdb < ./schemas/create_mysql
Modifikasi file konfigurasi Barnyard2 dengan perintah berikut:
vi /usr/local/snort/etc/barnyard2.conf
Set Values as given below:
config reference_file: /usr/local/snort/etc/reference.config config classification_file: /usr/local/snort/etc/classification.config config gen_file: /usr/local/snort/etc/gen-msg.map config sid_file: /usr/local/snort/etc/sid-msg.map config hostname: localhost config interface: eth0 output database: log, mysql, dbname=snortdb user=snortuser password=3ngin33r host=localhost
SAVE & Quit
12 - Barnyard2 ConfigChange Copy Required Files from Snort Source Directory:::

Testing Snort:
It’s time to test if Snort has been installed and configured correctly by using this command:
- /usr/local/snort/bin/snort -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth0
“Commencing packet processing” must be shown at the end of the execution of the command, this means Snort is Installed & configured correctly. 13 - Test Snort To set Snort to start automatically on your machine edit the rc.local file with the following command:
- vim /etc/rc.local
Add following lines before “exit” command.
ifconfig eth0 up
/usr/local/snort/bin/snort -D -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth0 /usr/local/bin/barnyard2 -c /usr/local/snort/etc/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard2.waldo -D
SAVE & Quit by :wq!
