Wrapper for the libtins library. Libtins can be used to sniff network packages, or to generate network pacakages yourself. See the tutorial section of libtins to see how more advanced uses
The addon currently implements a simple packet sniffer ofxSnifferSimple running in a background thread, and a http interpreter. This makes it super easy to sniff http traffic. But the addon can also be used just as a way to include the libtins library that has many many other uses.
Note: If you dont want to build the libraries yourself, then download the release instead
The static libraries are build with apothecary. After you have cloned the addon to your addons folder, run
cd scripts/apothecary
./apothecary update ofxSniffer
This will build libtins and libpcap. Currently only tested on mac os, but should work under linux and windows (with some modifications to the formula).
Permission denied opening dev/bpf0
In some cases you need to gain access to read from you network card. This might manifest itself on OS X as (cannot open BPF device) /dev/bpf0: Permission denied (See more on issue #2). You can fix this by running the command sudo chmod o+r /dev/bpf*.
This library will give you limited access to button presses from amazon dash buttons (limited as all it does is listen for the ARP request when you press the button and it turns on- still usefull and quite cheap for a long life battery powered wifi button for a more detailed and complicated hack see here http://hackaday.com/2015/08/12/amazon-dash-hack-it-to-run-your-own-code/).
To receive these button presses just follow the instructions here https://www.amazon.com/gp/help/customer/display.html?nodeId=201746340 but stop at part 4 of the isntructions (ie don't select a product to order with the dash). This setup will remember the wifi SSID and password you associated your button with. Repeat for as many buttons as you like. Once the buttons are associated with your network you can disconnect from the internet if you like.
Now you can run the example_amazon_dash, when you press the button it should give an arp request result and show the mac address of the button (it will also give a timestamp of the button press). To identify each button and separate it from other ARP requests on your network just check the mac address of the incoming request.
