This recipe requires installing the Scapy library (> 2.2), which can be obtained at http://www.secdev.org/projects/scapy/files/scapy-latest.zip.
At the time of writing, the default Scapy release works with Python 2, and does not support Python 3. You may download the Scapy for Python 3 from https://pypi.python.org/pypi/scapy-python3/0.20.
