<span style="color:red;">'''ATTENTION''': This tutorial will provide additional '''practice''' with some interesting system administration skills. This does not provide any practice for your '''assignments''' relates to an interest topic and is not NOT worth marks.</span><br><br>
In this investigation, you will first ''download'' and ''install'' the '''VirtualBox''' VM application on your home computer,<br>then you will then ''download'' and unzip the '''Knoppix Live Distribution VM''' file to your computer.
# Launch the '''Knoppix''' Linux distribution by clicking the '''Launch''' button.<br><br>''''''NOTE:'''''' Your '''file manager''' will open and display both the '''Knoppix virtual machine icon''' and a '''Knoppix Installation ISO file'''. You will be launching the Knoppix Virtual machine in the '''Virtualbox''' application.<br><br>
# '''Double-click''' on the icon Knoppix.vbox in the Virtualbox menu.<br><br>
# Another dialog box will appear. '''Double-click''' on the '''Switch''' button when prompted to enter '''scale mode'''or '''Switch''' to scale mode.<br><br>'''NOTE:''' You should notice that you can switch between your Knoppix VM and your Windows computer which is referred to as the '''host machine'''.<br><br>

# Open a '''File Manager''' application and '''navigate''' to directory that the '''Knoppix.zip''' file<br>was downloaded (eg. '''Downloads''').<br><br>[[Image:knoppix-file.png|thumb|right|280px|Knoppix VM file contained in the zipped file. '''Double-click''' '''Knoppix.vbox''' file to launch the '''Knoppix Live Linux''' Distribution.]]
# '''Unzip''' the downloaded zip file (In MS Windows: ''Right click'' and Select "''Extract All''" )<br><br>'''NOTE:''' The contents of this zipped file should appear in another file manager window.<br><br>
# Navigate to the folder containing the ''extracted zipped files'' and '''double-click''' the file called '''Knoppix.vbox''' to launch the Knoppix VM.<br><br>'''NOTE:''' By '''double-clicking''' on this file (even if the VirtualBox application is not running)<br>it will launch the VirtualBox application and start the Knoppix virtual machine.<br><br>'''For Mac Users:''' If you experience an error message regarding the Kernel extension,<br>click on '''System Preferences''', select '''Security and Privacy'''<br>and click to '''allow Oracle''' service extensions to run on your machine.<br><br>If you have difficulty running Knoppix on your home machine/laptop you may ask your <br>'''Learning Centre ULG leaders''' for additional help in troubleshooting why Knoppix<br>is not working on your home machine/laptop.<br><br><table align="right"><tr valign="top"><td>[[Image:knoppix-start-menu.png|thumb|right|150px|'''Knoppix Start button''' (icon on the '''left''').]]</td><td>[[Image:knoppix-desktop.png|thumb|right|280px|The '''Knoppix Linux desktop environment''' has a similar look as the MS Windows desktop environment.

This is a '''graphical Linux distribution''' which will start-up in a desktop environment.<br><br>'''NOTE:''' You are '''NOT''' prompted for a ''username'' and ''password'' because this is a Linux Live distribution and you have been assigned a '''generic account'''.<br><br>'''NOTE:''' If you are using MS Windows, press the '''RIGHT CTRL''' key to change to other applications by pressing '''ALT-TAB'''.<br>When you want to use Graphical Linux (i.e. Knoppix screen), click in the screen to focus and use that screen.<br><br>
# '''Click''' the '''Knoppix Start button''' (refer to <u>left</u> icon in diagram on right). In the '''Knoppix menu''', select '''System Tools'''<br><br>[[Image:xterm.png|thumb|right|280px|The '''Konsole''' application will display the Bash shell to issue Linux commands.]]
# In the '''system tools''' menu, and select '''Konsole''' to launch a terminal application.<br><br>'''FYI:''' To '''increase''' font size, press '''ctrl+''' to '''reduce''' font size, press '''ctrl-'''.<br>You can drag the Konsole terminal window from the bottom-right corner<br>to increase the window size.<br><br>
# When prompted, enter your '''password''' (remember that password does not "echo-back").<br><br>Were you able to connect to your Matrix account?<br><br>
# Confirm that you are in <u>your</u> '''home''' directory on your Matrix account.<br><br>
# Use a '''text editor''' (''nano'' or ''vi'') to create a file in your current directory called '''myvm.txt'''<br>and enter the following text displayed below. Make certain there are ONLY 3 lines:<br><br><span style="font-family:courier;font-weight:bold">This is line 1<br>This is line 2<br>This is line 3</span><br><br>
# '''Save''' editing changes and '''exit''' the text editor.<br><br>
# Confirm that you created this file and confirm that the contents of this file are correct.<br><br>Let's run a <b>shell script</b> to check that you created the '''myvm.txt''' file (with correct file contents) in your home directory.<br><br>
# Use the ''Knoppix start menu'' to '''launch''' a '''<u>graphical</u> file manager'''<br>('''Hint:''' ''Accessories'' -> ''Files'').<br><br>
# In the file manager, search for your word processing document file and your downloaded shell script that were contained on your home directory.<br><br>Does your word processing document or your downloaded shell script exist?<br>If not, why?<br><br>[[Image:frozen-bubble.png|thumb|right|200px|The '''Frozen-Bubble''' arcade game.]]
# Open the ''Knoppix start menu'', select '''games''' and try running a few games<br>(a few recommendations are: '''Frozen Bubble''', and '''Extreme Tux Racer''' and '''Open Arena''').<br><br>Now that you have had an opportunity to use your Knoppix Linux Live distribution,<br>let's shutdown the VM and move onto the practice questions at the bottom of this tutorial.<br><br>
# Open the ''Knoppix start menu'' and select '''logout''' and '''shutdown''' to end your Knoppix Live session.<br><br>
