My good friend Justin has released his second book on using Python called Black Hat Python (you should buy a copy or two from http://www.nostarch.com/blackhatpython).
I was fortunate to be a tech reviewer for the book. I learned so much from Justin and from the real tech reviewer, Dan during the development of the book. Thank you Justin and Dan.
For the section on Paramiko, I created a diagram to explain SSH tunnelling. Unfortunately, my original diagrams wouldn’t show up very well in printed format so I thought I would share them here.
