JAM WIFI NETWORK IN UBUNTU & BACKTRACK

We see WiFi where in these days. the use of WiFi is now growing day by day because of smartphones. people wants to crack WiFi password. cracking WiFi password is easy. but now instead of WiFi cracking many peoples are searching WiFi jamming. so this article is about how to jam a WiFi network easily for this you need a Linux OS i.e Ubuntu and Backtrack. so lets start

If you have UBUNTU or BACK TRACK installed ,then you can start from step 7 directly you can skip first six step. If you have windows user start from here.

Step 1: Download Backtrack 5 R2 here as .iso for 32 bit:
and 64 bit

Step 2: Download UNetbootin for Windows
Step 3: Insert your FAT32 formatted flash/hard drive and open UNetbootin.

Step 4: At the bottom of UNetbootin you'll see it says Disc Image. Select ISO and find your file.
             Type: USB-drive.
             Letter: H:\ or whatever your computer says.
             Then press on OK and let it finish.

Step 5: When it's done, press on Reboot now and when you're booting, remember to boot on your                    flash/hard drive. I use F12 when I'm booting to change, but it depends on each computer.
Step 6: Select Default, and wait for it to boot. When it's done booting, write "startx" in the console so              it will start your desktop.

Step 7: Connect to your favorite WiFi network. Go to the "start icon" in Backtrack, go to Network                  and find "Wicd Network Manager". Connect to your wireless.

Step 8: Open Terminal and write:
wget http://wifijammer.googlecode.com/files/wifijammer_0.1.sh

After the transfer has completed you now type:
chmod +x wifijammer_0.1.sh

Now you write:
sudo ./wifijammer_0.1.sh wlan0

When that's done, you type in "scan" when it asks you to.

Step 9: You will see a lot of text when it scans. It will look like this:

You can see it says "CH" in the window. That means channel. On the picture, the ESSID is the WiFi's name. As you can see, the network with ESSID "openn" is on channel 9.

Wait for the scan to complete, and then (in this example) type in "9" for channel 9.

It will now jam all connections on channel 9, so that the WiFi "openn" will be unavailable. On the picture there's also a network with ESSID "Playh" on channel 9.. That one will also be unavailable.

In some cases, it might jam so hard, that laptops/WiFi searchers won't be able to scan for any WiFi signals at all.
