Beacontalk - Peer to peer chat-program that sends data over Wi-Fi without associations

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 install

Put your wireless card into monitor mode and pick a channel

$ ifconfig wlan0 down; iwconfig wlan0 mode monitor; iwconfig wlan0 channel 1; ifconfig wlan0 up

Run the program by doing

$ ./beacontalk wlan0

Look at the source on github, or download a tarball.
