Here is a slide by slide guide on how to setup and create virtual machines, and even network them together. This is really useful to know about if you want to simulate setting up servers, networks, and various technologies and then test them. For those who are into cyber security you can safely practice your skills! You don't even need to spend money on a bunch of additional hardware!

Command Injection is a technique for gaining access, or getting a system to perform unauthorized actions. I've written up a tutorial/walk-through for a step by step lab on how to do this. It involves some setup with two virtual machines. Command Injection Walk Through Document HERE . Knowing a little bit about shells is also useful.
