?Familiarize yourself with the fundamentals and functionalities of SDN

?Improve your skills to become the next-gen network engineer by learning the various facets of Python programming

Description

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.

What you will learn

• Develop TCP/IP networking client/server applications

• Administer local machines IPv4/IPv6 network interfaces

• Write multi-purpose efficient web clients for HTTP and HTTPS protocols

• Perform remote system administration tasks over Telnet and SSH connections

• Interact with popular websites via web services such as XML-RPC, SOAP, and REST APIs

• Monitor and analyze major common network security vulnerabilities

• Develop Software-Defined Networks with Ryu, OpenDaylight, Floodlight, ONOS, and POX Controllers

• Emulate simple and complex networks with Mininet and its extensions for network and systems emulations

• Learn to configure and build network systems and Virtual Network Functions (VNF) in heterogeneous deployment environments

• Explore various Python modules to program the Internet

Have you ever read a networking textbook? Do you remember all the interesting protocols, SDN systems, network modeling, etc. that was discussed but which you never go to work with? Just kind of read about it and moved on?This is the first cookbook I found in any language that gives such a broad survey of networking. Why that is I don't really know. But show me a cookbook that covers all these topics:multiplexing servers, IPv6, UNIX domain sockets, network interfaces, FTP, CGI, POP3, IMAP, big/little Endian, advanced use of sockets, SMTP, remote shell scripting, SOAP, REST, XML-RPC, network modeling, Mininet, SDN, VMware, BGPThere's alot more advanced stuff I didn't mentionI see people complaining about the initial script. Well... I'd like to point out that the first script runs in Python2. It said run it in Python3, yes this was a mistake but it isn't something anyone that knows python should have any difficulty noticing. I didn't buy the book to complain, I bought it to learn something, and I learned alot from this book.It could have been written better, but the weird fact this sort of material is so hard to find cookbooks on, combined with the fact it's just basic information, is why I have given it 5 stars.

A lot of the time, you get trapped in the python's ecosystem of network-made-simple tools without any thought. Looking at things from a more broad perspective is always welcome for both teaching and practical purposes.

I'm getting sick of Packt books. In this one, the very first script is wrong: it left out parentheses and so an error occurs.Packt, a piece of advise: have someone half-way knowledgeable review your books before releasing them to the public.

H. S. Bassi Feb 24, 2018

first exercise does not work due to a bits of missing code:fyi: now not looking forward to other Packt pub books i bought due to this.import sockethost_name = socket.gethostname()ip_address = socket.gethostbyname(host_name)print"Host name: %s" %host_nameprint"ip address : %s" %ip_addresswith all these miss use of %s and % it makes so confusing how about making the code more cleaner so people can read it:here is a example of exercise 1.2 rewritten so its more easier to understand with out the fluf :)import socketremote_host = 'www.python.org'print("IP address of" + remote_host + socket.gethostbyname(remote_host))yes i removed the method "def" function as 1 this is not in a class and this code is only doing one function not many methods included in thisi also removed the "try" error handling module as there is no need for it as there is nothing to execute after should it failow and the %s have gone yes i removed the stringing crap out of the code as its confusing for people that want to understand how its working this method above makes it so much more cleaner for some one to read and understand on what the code is doing!PACKT pub please remove the fluf in your book no need for it. also try the exercises before publishing the books
