AirHarvest

The Apple AirPlay and RAOP protocols are the foundation of AppleTV and all AirPlay compatible hardware. The two protocols are continuesly evolving and new features are added. Clément Vasseur did a fantastic job documenting most of the two protcols in 2012, but since then a lot have happended.

This project is a first step in trying to fully uncover the two protocols.

Installing an running this software on your computer will collect and send information about all AirPlay and RAOP compatible devices on your network to a public database. From this data and a lot of hard work it's my hope that we can reverse engineer the two protocols.

Installation

This is a Node.js module and requires the Node.js package manager to install.

npm install -g airharvest

Run it!

Just run the airharvest command from your command line :)

What does the collected data look like?

This is an example of what kind of RAOP data is collected:

{
    "type": "raop",
    "port": 5000,
    "txt": {
        "cn": "0,1,2,3",
        "da": "true",
        "et": "0,3,5",
        "ft": "0x5A7FFFF7,0xE",
        "md": "0,1,2",
        "am": "AppleTV3,1",
        "pk": "****************************************************************",
        "sf": "0x44",
        "tp": "UDP",
        "vn": "65537",
        "vs": "200.54",
        "vv": "2"
    }
}

This is an example of what kind of AirPlay data is collected:

{
    "type": "airplay",
    "port": 7000,
    "txt": {
        "deviceid": "***",
        "features": "0x5A7FFFF7,0xE",
        "flags": "0x44",
        "model": "AppleTV3,1",
        "pk": "****************************************************************",
        "srcvers": "200.54",
        "vv": "2"
    }
}
