When it comes to the most recent generation of computers, there is an option to start an operating system right from a USB stick, without an actual installation process. This may be an option to use or test a different operating system without affecting in any way the one that is already installed.

Starting from version 8.10, Ubuntu can be installed on a USB stick in a more easy way by every single user, regardless of their knowledge in Linux. To perform the installation, the user must have a version of 8.10 or later on CD and a USB stick with a capacity of at least 700 MB free space available, but this can vary according to the version of Ubuntu that you want to use for this process.

To install Ubuntu on the USB stick, you can simply boot the Live CD mode of Ubuntu or alternatively, if already installed on your on your system, you can follow the following simple procedure to do this, which is described in some basic steps below.

First of all, you need to access the Ubuntu menu bar, via System> Administration, choose Create a USB startup disk.

At this point, you will be asked to specify the source disk image of Ubuntu. If you have the Ubuntu CD in optical drive, it should appear in the list and will be selected. Otherwise, click Other and specify the location of the image. The .iso format will do it, but other versions may work as well.

When completed, you can use the stick on any computer that can boot from such units. Just tell the computer’s BIOS to use this option and restart the respective machine. The same procedure can be applied for the any distribution of Linux, so this is a helpful tutorial for everyone.

One of the great problems of interoperability between Linux and Windows has been the impossibility of Linux systems for joining a Microsoft Windows network. Subsequently, several standards to achieve this were developed over the years (see Samba), but they were far from offering normal user the chance to achieve this easily.
The infrastructure of many companies around the world, of all sizes, also relies on the use of a Windows domain. In all companies, one priority always stands out. That is to reduce information costs and expenses. Because of this, many of them have opted for the use of computers with Linux operating systems. But in many cases their integration into Active Directory environments was a problem.
Recently, a new tool was created to facilitate the full integration of a Linux system in an AD environment. And as far as today, it seems very promising. Thanks to likewise-Open5 (http://www.likewiseopen.org/), the difficulty of integration is almost null.

The following lines will illustrate the inclusion of Ubuntu in a Windows domain via likewise-Open5.

Installation

Likewise-Open5 Installation process is very simple. It can be done both through the graphical environment and command line. We will use the second variant. Therefore, a new terminal window must be open, in which you specify the following command:

sudo apt-get install likewise-open5

This command should resolve all the dependencies necessary to prepare the machine to be integrated in the Windows domain.

Adding a new machine

To actually add the machine, specify the following command in the terminal window:

sudo domainjoin-cli join domain used

Where DOMAIN is the area used for integrating the machine, and USER is the username that has the corresponding rights. You will be asked for your user password, and once successfully logged in, you are officially added the desired machine.
