Testimonials

Bruce Wilson

Like all other courses I've taken from David his attention to detail and explanation of the technologies are excellent! I would definitely recommend this course to a colleague looking to skill up and build on networking concepts!!!!

Kevin McFarland

I like the way that David reinforces through multiple show commands. Which enforces a habit to continually verify your configurations each step of the way... and not to assume everything is correct, only to discover later that mistakes were made, which can become a major frustration!

Daniel Tecle

Great voice, straight forward. Answers common questions during the lecture. Of all the Python dabbling I have done, this is the course that got me moving. In fact I have uploaded my first very simple Python script to GitHub, after many iterations.

Shailesh Patel

This is the best series on python and networking i have seen. author is A+++++++ please keep it up as you are really great in helping others start and accelerate learning all the best
