Overview of this book

Python Network Programming Cookbook - Second Edition highlights the major aspects of network programming in Python, starting from writing simple networking clients to developing and deploying complex Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) systems. It creates the building blocks for many practical web and networking applications that rely on various networking protocols. It presents the power and beauty of Python to solve numerous real-world tasks in the area of network programming, network and system administration, network monitoring, and web-application development. In this edition, you will also be introduced to network modelling to build your own cloud network. You will learn about the concepts and fundamentals of SDN and then extend your network with Mininet. Next, you’ll find recipes on Authentication, Authorization, and Accounting (AAA) and open and proprietary SDN approaches and frameworks. You will also learn to configure the Linux Foundation networking ecosystem and deploy and automate your networks with Python in the cloud and the Internet scale. By the end of this book, you will be able to analyze your network security vulnerabilities using advanced network packet capture and analysis techniques.

Preface

Saving packets in the pcap format using the pcap dumper


The pcap format, abbreviated from packet capture, is a common file format for saving network data. More details on the pcap format can be found at http://wiki.wireshark.org/Development/LibpcapFileFormat.

If you want to save your captured network packets to a file and later reuse them for further processing, this recipe can be a working example for you.

How to do it...

In this recipe, we use the Scapy library to sniff packets and write to a file. All utility functions and definitions of Scapy can be imported using the wild card import, as shown in the following command:

from scapy.all import *

This is only for demonstration purposes and is not recommended for production code.

The sniff() function of Scapy takes the name of a callback function. Let's write a callback function that will write the packets onto a file.

Listing 8.2 gives the code for saving packets in the pcap format using the pcap dumper, as follows:

#!/usr/bin/env python 
# Python...
