Scapy's primary purpose is to build and transmit arbitrary packets, so let's get started! ls() displays all of the available protocols and lsc() lists all of the scapy command functions.Īrpcachepoison : Poison target's cache with (your MAC,victim's IP) coupleĪrping : Send ARP who-has requests to determine which hosts are upīind_layers : Bind 2 layers on some specific fields' valuesĬorrupt_bits : Flip a given percentage or number of bits from a string These commands are actually Python functions, which is why they must be called with the ending parentheses. The two most important commands to remember for scapy are ls() and lsc(). You may see some warnings like the two above regarding absent optional dependencies or missing routes don't worry about them. Won't be able to use psdump() or pdfdump(). INFO: Can't import python gnuplot wrapper. Note that you'll need to invoke scapy with root or administrative rights in order to send or sniff packets. Launch the scapy executable to get started.

For a quick introduction to Python you can check out the official tutorial, but building packets with scapy requires only minimal Python knowledge. The examples here use scapy's shell, which is essentially a pre-configured Python environment. Scapy is typically used as an interactive Python interpreter, but its libraries can also be imported for use in your own code.

scapy is installed per the typical Python package installation mechanism on Linux: The most recent version of scapy at the time of writing is 2.1.0, and that's what the examples provided in this article use. The latest version of scapy is available for download here.

To run scapy, you'll need to have Python installed. I've used scapy in labs for my articles a few times before, but today we'll be looking at scapy itself and why it's an invaluable component of every networker's virtual toolbox. Scapy is a Python framework for crafting and transmitting arbitrary packets.
