VirtualBox allows you to run virtual machines on your computer that share the computer's hardware resources with the host operating system. VirtualBox also provides the ability to use dynamically growing storage, which allows you to create drives that are (virtually) the same fixed size inside, but the physical image files themselves are only a few megabytes in size when created and grow depending on the amount of data loaded. This is unfortunately not true backwards, so if you delete something from the virtual machine, for example, the size of the physical image file on the virtual storage device will unfortunately not be reduced. In this description, we will look at how to manually shrink the dynamically growing image files of our VirtualBox virtual machines to the size actually used on Linux and Windows systems.

If you often work on remote file systems, it is a good idea to mount them on your own file system so that you do not have to log on to another machine or connect to any server every time, but use that storage as if it were your local directory.

In this tutorial, you will learn about KeePass, which provides a high level of security for our passwords and other access information on Windows, Linux, and Android systems. After installing the program on a Linux computer and an Android mobile device, we will review the key features of the password management system: We will create a new database and create basic structures by creating groups and entries.

This tutorial describes how to access SSH / SFTP file systems on remote Linux servers via an encrypted channel on your home computer.

In this tutorial I will show you how to create and prepare a virtual machine for a Linux guest system in VirtualBox.
