Python Network Programming

By: Abhishek Ratan, Eric Chou, Pradeeban Kathiravelu, Dr. M. O. Faruque Sarker

Overview of this book

This Learning Path highlights major aspects of Python network programming such as writing simple networking clients, creating and deploying SDN and NFV systems, and extending your network with Mininet. You’ll also learn how to automate legacy and the latest network devices. As you progress through the chapters, you’ll use Python for DevOps and open source tools to test, secure, and analyze your network. Toward the end, you'll develop client-side applications, such as web API clients, email clients, SSH, and FTP, using socket programming. By the end of this Learning Path, you will have learned how to analyze a network's security vulnerabilities using advanced network packet capture and analysis techniques. This Learning Path includes content from the following Packt products: • Practical Network Automation by Abhishek Ratan • Mastering Python Networking by Eric Chou • Python Network Programming Cookbook, Second Edition by Pradeeban Kathiravelu, Dr. M. O. Faruque Sarker

Installing a Python package remotely


While dealing with the remote host in the previous recipes, you may have noticed that we need to do a lot of stuff related to the connection setup. For efficient execution, it is desirable that they become abstract and only the relevant high-level part is exposed to the programmers. It is cumbersome and slow to always explicitly set up connections to execute commands remotely.

Fabric (http://fabfile.org/), a third-party Python module, solves this problem. It only exposes as many APIs as can be used to efficiently interact with remote machines.

In this recipe, a simple example of using Fabric will be shown.

Getting ready

We need Fabric to be installed first. You can install Fabric using the Python packing tools, pip or easy_install, as shown in the following command. Fabric relies on the paramiko module, which will be installed automatically:

$ pip install fabric

Currently the default Fabric does not seem to support Python 3. You may install fabric3 to fix this...
