Following is what you need for this book:

To get the most out of this book, some basic hands-on network operation knowledge and Python knowledge is recommended. Most of the chapters can be read in any order, except for Chapter 4 and Chapter 5, which introduce base technologies that will be used later in the book. Besides the basic software and hardware tools introduced at the beginning of the book, new tools relevant to each of the chapters will be introduced in the respective chapters. It is highly recommended to follow and practice the examples shown in your network lab.

Refer to the Errata for corrections of typos and other mistakes and improvements like refactoring code.

pyhnet: a high level python networking library

Goal: to make networking in python much easier than it currently is.

• An easier to use TCP socket that can do almost anything the standard socket could
• Consistent error messages between platforms
• Unblock blocking operations on .close()
• Easy multiplexing of streams
• Easy reply/wait for reply
• Optional automatic pickling of messages
• Remote proxy objects. you can send a proxy of a python object to the other side any methods called on the remote proxy will be sent through the connection and called on the local object. Any exceptions thrown in the call will be packaged up and sent back.

There are a couple examples in example.py that should get you going.

pyhnet starts with the plain python sockets (which have a quite varying behavior between platforms) and adds a simple wrapper around it that gives 98% of the functionality of the plain sockets, but is much easier to use and behaves consistently across platforms. Specifically, exceptions raised should always be the same for a given type of error and .close() will always unblock any blocking socket operations.

pyhnet provides several other wrappers than can be stacked together around the lower level byte stream to convert it to a packet stream, replyable packet stream or a pickled replyable packet stream. (the last, called HNetTCPSocket, is the default)

I’m planning on adding support for UDP eventually but haven’t gotten around to it yet. If you have a burning need for it let me know; it shouldn’t be very hard to add it.

Sorry the documentation is sparse, but the source is relatively readable (and short)

Mastering Python Networking. 4 Ed

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In Mastering Python Networking, Fourth edition, you’ll embark on a Python-based journey to transition from a traditional network engineer to a network developer ready for the next generation of networks.

This new edition is completely revised and updated to work with the latest Python features and DevOps frameworks. In addition to new chapters on introducing Docker containers and Python 3 Async IO for network engineers, each chapter is updated with the latest libraries with working examples to ensure compatibility and understanding of the concepts.

Starting with a basic overview of Python, the book teaches you how it can interact with both legacy and API-enabled network devices. You will learn to leverage high-level Python packages and frameworks to perform network automation tasks, monitoring, management, and enhanced network security, followed by AWS and Azure cloud networking. You will use Git for code management, GitLab for continuous integration, and Python-based testing tools to verify your network.

What you will learn

• Use Python to interact with network devices
• Understand Docker as a tool that you can use for the development and deployment
• Use Python and various other tools to obtain information from the network
• Learn how to use ELK for network data analysis
• Utilize Flask and construct high-level API to interact with in-house applications
• Discover the new AsyncIO feature and its concepts in Python 3
• Explore test-driven development concepts and use PyTest to drive code test coverage
• Understand how GitLab can be used with DevOps practices in networking

Who this book is for

Mastering Python Networking, Fourth edition is for network engineers, developers, and SREs who want to learn Python for network automation, programmability, monitoring, cloud, and data analysis. Network engineers who want to transition from manual to automation-based networks using the latest DevOps tools will also get a lot of useful information from this book.

Basic familiarity with Python programming and networking-related concepts such as Transmission Control Protocol/Internet Protocol (TCP/IP) will be helpful in getting the most out of this book.
