Learn Network Programmability and Network Automation using GNS3 and Python version 3.

This course is based on Python 3.

Want to program networks using Python, but not sure where to start? Well, this course will show you how you can start programming Cisco networks within 20 minutes.

This course was created for network engineers. There are too many other Python courses out there that try to make network engineers software developers. Instead of teaching network automation, they teach you Python theory. This course is different. 

This course is practical. I won't talk about programming in abstract terms and make you wait before you can start automating networks. I will show you how you can quickly and easily start network programming by using GNS3, Cisco IOS and Python.

You will see demonstrations of the configuration of both Cisco routers and switches in GNS3. For example, how to configure multiple VLANs on a multiple switches, or how to configure OSPF on a router and more.

This course shows you practical examples of using Python to programmatically configure Cisco network devices rather then just talking about it.

The days of configuring Cisco networks only with the command line interface (CLI) are drawing to a close. You need to add network programmability using Python and APIs to your skill set.

Learn how to automate networks using:

- Telnet

- SSH

- Paramiko

Netmiko

NAPALM

Tools such as NAPALM and Netmiko make it easy to configure and interact with network devices using an API such as NETCONF or using SSH. Don't reinvent the wheel. Use the tools available to you to quickly and easily automate your networks.

Some comments about the course:

"Knowing the material from just the first video would have saved me hours of work and rework in the past." 

"It's the easiest, most fun, and most valuable course I've completed yet on Python Programming for Networking. Love it! Thanks again David!!!" 

"Excellent course on Network Programming using Python with lot's of practical network configuration examples."

"Great way of explanation.Nice video and inspiring words! Thank you so much David. You are genius."

"I've been doing network automation for a while, even so, I've learned new things through this course. The instructor start from a basic example, adding improvements in each step. It's a skill that's worth it."

"A must for all network engineers who want to learn python!!! I had very "very" basic programming skills, and couldn't just get the bridge between network and programming (mainly Python - since that's where the hype is now), this course was amazing, I have never been glued to a training course since I can remember. The couple of things I loved the most about this course: 1- David's clear voice. 2- Real world application, not only will David interduce different real-world practical modules that you can import and use, but he shows you how to apply them on ios devices."

"Excellent course on Network Programming using Python with lot's of practical network configuration examples. High quality content."

The world is becoming interconnected on an unprecedented scale with more services being provided on the Internet. Applications ranging from business transactions to embedded applications, such as those found in refrigerators, are connecting to the Internet. With isolated applications no longer being the norm, it is becoming increasingly important for applications to be network enabled. The goal of this course is to provide the student with the necessary skills to develop Java applications that connect and work with other applications and services across a network. You will be introduced to a wide range of networking options that are available using Java, which will enable you to develop applications using the appropriate technology for the task at hand.

The first 1st,2nd and 3rd section of this course is to introduce the network principles and associated terminology with which the student will need to be familiar in order to make sense of the later sections and lectures of this course. The first section of this course is entirely generic (as far as any programming language is concerned) and it is not until the next sections that we will begin to consider how Java may be used in network programming. If the meaning of any term covered here is not clear when that term is later encountered in lecture, the student should refer back to previous lecture to refresh his/her memory.

Clients and Servers in Java Network Programming

The most common categories of network software nowadays are clients and servers. These two categories have a symbiotic relationship and the term client/server programming has become very widely used in recent years. It is important to distinguish firstly between a server and the machine upon which the server is running (called the host machine), since I.T. workers often refer loosely to the host machine as ‘the server’. Though this common usage has no detrimental practical effects for the majority of I.T. tasks, those I.T. personnel who are unaware of the distinction and subsequently undertake network programming are likely to be caused a significant amount of conceptual confusion until this distinction is made known to them.

Ports and Sockets in Java Network Programming

These entities lie at the heart of network communications. For anybody not already familiar with the use of these terms in a network programming context, the two words very probably conjure up images of hardware components. However, although they are closely associated with the hardware communication links between computers within a network, ports and sockets are not themselves hardware elements, but abstract concepts that allow the programmer to make use of those communication links.

What others have to say about this course?

"I have been programming since 1978 and wanted to learn python. I have had no java or OOP experience, and I tried several 'paper' tutorials but got little out of them. The first part of this course is a steady walk through the Python language at just the right speed. The instructor seems to touch all the basis in a logical and methodical way while providing examples and explanations. I can only conclude the instructor is a professional educator who spent considerable time structuring and organizing the course. The result is evident. THIS IS A GREAT WAY TO LEARN PYTHON!" by Larry Laswell

"I've tried learning from the books & multiple videos - most were too basic to make a practical app. Some books were too thick and made me sleep. But still none of the materials had the perfect balance like this course where all the basics were covered, instructions were concise, and Mihai walks you through how to create 7 practical apps step by step. I've also tried reading some advanced python book which didn't make sense because it was too advanced. Let me tell you, this is hands down "that course that takes you up to beyond the basics" to bridge you to the advance topics. Right now I'm hitting the advanced topics and it finally makes sense..." by Joon Park

"Usually I'm not doing courses review but this time I will make an exception. During time I took a lot of trainings but very few provided by Udemy proved as having the right approach in teaching the audience. I will mark this one as being one of my personal top three best trainings as content's quality, technical explanations, and additional learning materials perspective. Long story short this course is a very simple, straight forward way of learning Python for managing IT networks." by Johnny Stanescu

"This is a great course for network engineers who would like to start automating their tasks. Geared towards beginners, this course teaches the fundamentals of programming and applying those concepts to networking. There is a lot of fluff about python on the internet, however the instructor managed to put together the necessary information to start automating the network. A working knowledge of TCP/IP is needed to get the most out of this course. Should you understand every lecture, you will be ready to start writing your own scripts according to your needs. In particular, I loved the use of scapy, an amazing tool which should be in the arsenal of anyone working with TCP/IP." by Costin-Alin Neacsu

"I've seen the blueprint and some demo videos and I was convinced right away. Without a doubt, it's one of the best trainings a network engineer can have. It gives you actual valuable and marketable skills that you can use in your daily job. Mihai explains the topics really well, with practical examples making it a fun way to learn. Highly recommended." by Vlad Vlaicu

This course is about strengthening the Networking concepts and fundamentals with assignments side by side with theory. Through this course you will be able to :

1. Understand the Functioning of TCP/IP Stack (OSI Model). Understand the function of each layer in TCP/IP stack in good detail.

2. Explain the L2 routing concepts - Mac Addresses and ARP

3Explain the L3 routing concepts - IP Addresses and IP protocol

4. Understand the procedure of Dynamic construction of L3 Routing Table

5. Understand various ways to design a Linux TCP/UDP server program in C

6. Understand Socket programming in C 

7. Understand the Networking devices functioning - L2 switch and L3 router

8. Understand packet Journey through the layers of TCP/IP stack

9. Design and implement HTTP Webservers from scratch

10. Read and manufacture the network packets from scratch

11. Understand the concept of TLVs

12. Concept of packet Encapsulation

13. Understand Domain Name System (DNS)

14. Virtual LANs (VLANs) and Routing in VLANs

15. Broadcast Domain and Collision Domain

We Understand - Networking by its nature is inclined towards being a theoretical subject of study. To arouse the interest of the students ,we elaborate each and every topic of this course through an assignment or project.

This course is thorough. We explain the design, discuss the code flow and then guide the audience how to implement the particular concept design in detail in a step by step manner. All you need is a Linux OS running on your system to do this course.

Who should do this course ?

This course is meant for UG Computer science students, job seekers and professional developers. This is MUST do course for those who want to join MNCs as a developer. The topics covered in this course are of utmost importance from interviews aspects and students graduating in computer science and looking to seek an opportunity in MNCs as a developer should have Networking concepts at his/her finger tips. Better to have done Networking under graduate course, not mandatory. Job seekers trying for the position of Networking developers in product based MNCs System software development including Networking is an evergreen area. Internet will not going to be doomed ever.

Pre-requisite

There is no pre-requisite for this course, however, it shall be advantage if you know a little of C. We designed this course assuming student is a complete beginner in Networking and we raise the level of course gradually as we move from Basic to advance Networking concepts. 

Also, Please just do not sit and watch my codes. Write your own codes, even if it is same as mine !

We have a strong reasons to choose C as a language for this course:

1. The entire core networking development work is being done in C in industry. So, this reason alone is good enough that you should learn network development in C if you are aiming to join industry as a network protocol developer. 

2. Network equipment need to interact with underlying hardware - the ASIC chips. What could be a better language other than C when it comes to interact and program the hardware.

3. C is middle level language - not as low as assembly, neither as high as Java/Python. In C, its the programmer's responsibility to write every line of code to get the task done, unlike Java/Python which provides rich rest of libraries to do the most tasks for you. Using High Level Languages for learning network programming would obscure the low level details of networking - that is what is going behind the scenes. If you are are beginner in network programming, you must learn things from scratch and only C provides you the opportunity to do that. So, you must do all your assignments in C.

4. Networking is all about cooking up the packets and sending it out of wire. C will allow you to cook packets exactly the same way as you would like them to appear on wire. Lot of Bit level programming.  

5. If you are a beginner in Networking, pls refrain from learning network programming in High Level Languages such as Java Or Python. It is not job oriented thing to do in networking domain.

No Third Party libraries

Whatever logic you implement, you need to implement it from scratch. This course do not suggest taking help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third party libraries for commonly used data structures such as linked lists/Trees/Queues etc which saves a lot of time implementing these data structures.

What else along with the course ?

If you are aiming to become a developer, then, besides strong in Data structure and Algorithms, you should have clarity of concepts related to other Linux utilities. Networking is all about system programming, and you would be interested in learning other linux concepts of prime importance such as Inter Process Communication, Remote Procedure Calls etc. Please take a look at my other courses in this regard. These courses will summed you up as a more competitive developer in Networking & System Programming domain.

***** What a Fantastic Course!!! I really appreciate the efforts Abhishek has put in this course. He has put his sweat and heart into it. The way he explains things keeps you hooked on to this course. He directly gets TO THE POINT without beating around the bush. No author of any networking book can explain things like Abhishek is doing. What Abhishek is doing is that he is explaining the Meat of the subject. One would have to read 10 books to understand this. or perhaps more. There was a hunch in my heart that dont know networking clearly. This course meets my expectations with respect to content, clarity and teaching style with proper presentations. This course improves your understanding and removes the fear of not knowing...not only that, it injects a good amount of confidence about your knowledge of Networking...Thanks for coming up with such a course. Thanks Again.

***** Come across right course at right time. This course seems cover all important areas of networking. Author explains the topics in good detail and with good pace. This course looks like designed to beat technical interviews.

***** Great Course, instructor is very thorough and provide quick guidance and clear any doubts promptly with high availability. I really enjoyed this course. Networking has been a tough subject for me to learn, but this course has made it quite easy. I now have my concepts thoroughly clear ! Thanks Abhishek, and Udemy.

***** I am working as Firmware/Embedded engineer, and the courses from this guys are goddamn blessing. In the real industry, as he mentioned earlier, all network programming or Linux system programming must be implemented with C cuz C is a perfect language for accessing memory spaces and customizing serial communication with other chips. In the real industrial fields, no one is gonna teach you. You are the only one who needs to figure it out by yourself cuz everyone wishes you not to excel in workplace. Only one person can be a manager or supervisor. Take this guy's courses. Needless to say, quality guaranteed. If I could do hacking on this site, i am gonna crash his lectures. I do not want other people to get benefits from his lectures. It would be best if he makes a lecture for "making Operating System from scratch" :)

Course Description

With over 45 videos this online Java training course is designed to provide a solid foundation in Java network programming and network communication.

---------------------------------------------------------------

Learn something new

Network programming is one field which everybody uses but is still considered an advanced topic.

---------------------------------------------------------------

Open
Source Code

All
source code shown in this course is also available for download.
Students can create their own projects using
the downloaded java files.

---------------------------------------------------------------

Combine
theory with practice!

Each
chapter has an intro video to
cover basic theory needed to understand the rest of the material
covered.

In the first chapter you will learn the concept of network communication from the very basic fundamental level that needs to be understood by everyone.

Two other chapters are included in this course for those programmer who haven’t worked yet with java threads or java IO. These two are very important topics when you want to build a network application and I want to ensure that all students have the basics before we start to code Client – Server applications.

In the Socket (Java Socket programming) section you will start to write simple TCP servers or TCP clients. Also, you will learn how to create a multi-user or a multithreaded server and we are going to test each written application. We will connect multiple TCP clients to a multithreaded server and we will observe the TCP server behavior and how it makes to respond to multiple clients at the same time. 

In this chapter I will cover some other important network programming topics:

  • Scan a remote host for open ports

  • Get network interface hardware information

  • Validate an IP address in different ways

  • Ping a remote host address using java code

  • Browse internet using java code.

  • Web scrapping – get what data you want from a web page

UDP chapter focus on the difference between the most used Transport Layer protocols: TCP and UDP. We will write together an UDP server and an UDP client. The interesting part of this chapter comes after we will run the code. The next chapters present some useful applications:

  • Send an email

  • Transfer files between a server and a client using TCP sockets

  • A small web browser.

The code is explained in details, line by line. All the needed theory is presented in the application intro and we will test each application after the source code is explained.

So let’s start the interesting journey now!
