Beacontalk is a peer to peer chat-program that uses a method of sending data over Wi-Fi without associations. This program enables the user to send text to other in-range wireless devices also running the program. All received messages that are unique, are re-broadcast. This means that if nodes are places in a straight line, the data will be sent through a chain of nodes. Be wary of that this program is merely a proof of concept and does not use any encryption. Anyone with a package-sniffer will be able to decipher your messages.
To install the program
$ ./configure; make; make installPut your wireless card into monitor mode and pick a channel
$ ifconfig wlan0 down; iwconfig wlan0 mode monitor; iwconfig wlan0 channel 1; ifconfig wlan0 upRun the program by doing
$ ./beacontalk wlan0
