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*.
