From time to time, I experiment with different tools. In order to have the same environment and to keep my working machine clean from the garbage left after such experiments, I do my investigations in a virtualized environment. Usually, my guest operating system (OS) is Ubuntu Server because I usually use this OS in the cloud. Thus, to completely resemble my experience in the cloud I should have terminal access to the guest operating system. Unfortunately, by default after you have installed a guest virtual machine (VM) you do not have network access to it. Therefore, in this article I will show how to configure VirtualBox and guest OSes so that you get access to your virtual machines from the host, e.g., through terminal.
