Block Bittorrent Traffic Dengan IPtables

IPTABLES adalah program aplikasi user-space yang memungkinkan administrator sistem untuk mengkonfigurasi tabel yang disediakan oleh firewall kernel Linux (diimplementasikan sebagai modul Netfilter yang berbeda) rantai dan aturan ini menyimpan.

Untuk memblokir lalu lintas Bittorrent dengan IPTABLES Anda dapat mengedit / etc / sysconfig / iptables (CentOS):
nano /etc/sysconfig/iptables


Pertama Anda akan ingin menambahkan mata rantai tepat di atas aturan pertama

:RH-Firewall-1-INPUT - [0:0]

Kemudian tambahkan berikut di atas COMMIT line

# Torrent ALGO Strings using Boyer-Moore
