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.
