Blok Established Connection di Server dengan Cutter

Baru dapet "ilmu" baru untuk ngedrop establised connection di server. Caranya dengan menggunakan aplikasi cutter.

Cara menggunakannya cukup mudah. Misalnya anda ingin memblok koneksi http (port 80) dari IP 10.0.0.21, cukup dengan:

#cutter 10.0.0.21 80 

Cukup mudah bukan! Ini ada contoh yang saya ambil langsung dari websitenya:

cutter ip-address

Example: "cutter 10.10.0.45"

Cuts all connections passing through the firewall between any ports on the specified ip-address (either a "private" or "public" address) and any other hosts. This can be used to close down all incoming connections to a particular server, all outgoing connections from a particular client or all outgoing connections to a server.
cutter ip-address port

Example: "cutter 200.1.2.3 80"

Cuts all connections to or from the specified ip-address/port pair. This allows the user to be a little more specific than the previous example and allows targetting of specific services on specific hosts.
cutter ip-address-1 port-1 ip-address-2

Example "cutter 200.1.2.3 22 10.10.0.45"

Cuts all connections between ip-address-2 and ip-address-1/port-1. This allows the user to cut connections between a specified "client" and a particular service on a specified host. Our example closes host 10.10.0.45's SSH connection to server  200.1.2.3.
cutter ip-address-1 port-1 ip-address-2 port-2

Example: "cutter 200.1.2.3 22 10.10.0.45 32451"

Cuts the specific connection between the two ip/port number pairs given.
