![]() ![]() ![]() Running a script will require a root (administrator) privileges because Scapy uses a privilege-restricted low-level calls to capture packets. Sniff(iface="eth0", prn=handler, store=0) ![]() Note that the name of network interface on your device may differ. This example script (sniffer.py) will print out a summary of each captured packet. Below you can find a minimal example you can run on your computer. You can write your own code that will sniff exactly what you need. What more, scapy provides a wide range of features that help you filter and decode packets. You can create a custom packet sniffer in just few lines of code. In short, that interesting tool makes a packet capturing really easy. For those who need analyze some raw bytes – no worries, the raw data are also accessible. So, it hides all unfortunately low-level abstraction which we don’t really like in Python. But, instead of that, you can just use a powerful Python library – Scapy (see documentation), which exposes a user-friendly high level API. The common method of making a packet sniffer in User-Space is to use low-level operations on RAW sockets.
