Authentication of canceling authentication attack in WLAN

platform for Linux, using software for Aircrack-ng.

Cancellation of authentication attacks and the principle of association: constantly on the user issued a certificate of unsuccessful packets, to the AP users want to disconnect the data packets to reach the user can not normally connect the effect of AP, due to a large number of packets to achieve, belong to a traditional LAN denial of service attacks.

First is the installation of Aircrack-ng, the general step is to download the source code, compile the installation, detailed steps see http://www.maybe520.net/blog/1744/Click to open the link

The next step is to implement the cancellation authentication attack:

First set the network card to listen mode (note and promiscuous mode difference), sudo airmon-ng start wlan0

On the channel where the AP is located, sudo airodump-ng mon0

You can see the channel where the AP you're connected to

Switch to the channel where the AP is located, sudo iwconfig mon0 channel num (channel number)

Final packet blocking authentication and association, sudo-0 10-a AP mac-c user's Mac Mon0

You can see that this machine is in the contract, while the user disconnects and cannot connect to the AP, if the local packet is terminated, you can see the user can connect to the AP again.
