In this assignment you will create ONE virtual machine and install a GUI version of Linux.
1. VM Setup
Download this worksheet VM_Worksheet
Log into http://vm.cs.dixie.edu
You can download instructions containing pictures here: VM_Bionic_GUI_Install_Notes.pdf
Find and notate your
base allocated ip - it will be the first one in the ip range list. The base ip will begin with 144.38. Make sure to write down your ip addresses on the worksheet.
Create yourself a new virtual machine using the following settings and click the plus sign:
- 2048 MB RAM - 2 CPU - 16 GB Hard Drive
Start your new virtual machine by selecting D drive and bionic_desktop installation image disk. Click the green button.
If your machine won’t start - you may have to delete the machine and create a new one. Sometimes the machines don’t create correctly.
To Delete your Virtual Machine:
- click the red button on the right to turn off your VM. - After it shuts down - click the trashcan on the left to delete the machine.
1a. VNC Viewer
Create a tunnel and Open your VNC Viewer - Written instructions provided for your OS in Canvas under VNC Connect From Home
Some options are:
- TightVNC : Windows - Chicken of the VNC : Mac - GTK VNC Viewer : Linux - Vinagre : Linux - Remmina : Linux
2. Complete The Installation
During the install Use these settings
- Click Continue on default English install - Choose Minimal intallation - Erase the disk and install Ubuntu - Write the changes - Denver timezone - Hostname will be the name of your computer. Choose a good one such as <username>-Linux-GUI - Username should be your CIT username - Password should be your CIT password - Require Password at login
After the installation finishes, restart the server by clicking the RED Power Button in vm.cs.dixie.edu. Wait for the machine to enter the red zone, then click the GREEN power button using C drive and no installation disk.
Issues with the VM GUI are because everyone is creating these machines at once in the VM Farm in many different classes. GUI’s take resources, so we get to share. The issues are NOT part of the Linux GUI.
2a. Connect your VM to the internet
In your Virtual Machine that you see in the VNC Viewer
- Click the wi-fi or internet symbol in the upper right-hand corner. You may have to increase the window size or scroll up to find the symbol. - Select Wired Connected - Select Wiered Settings - Click on the settings wheel for Wired - Click on IP4 settings and Select Manual Method
Now Enter your Network with the following information (This should be on your VM_Worksheet):
- Address - enter your base ip + 3 - To find base + 3 start with your base: - My base is 18.104.22.168 - Then add 3 to the final number: - The ip of my VM will be 22.214.171.124 - Netmask - 255.255.255.248 - Gateway - base + 1 - Same thing here, base = 126.96.36.199 - My gateway will be 188.8.131.52 - DNS Servers - 184.108.40.206, 220.127.116.11
When it is all complete - click Apply.
It is normal to have issues with the interface not accepting your input. Click Cancel or Save and start again.
To get Linux to read the settings you will need to turn your machine off and back on again.
The internet icon will change - it will no longer contain a “?”.
You can test that the internet is working by running firefox.
3. Install Openssh-server
This assignment is a GUI Experience. Our first experience is using terminal in the GUI.
Installing command line is a little bit different than installing through the GUI. However, it is required to be able to connect to the new Virtual Machine through a terminal.
- Use the `Finder` in the lower left hand corner indicated by 9 dots, to search for and open a `Terminal` or `XTerm` - type the following commands - sudo apt update - sudo apt install openssh-server
Test your connection by ssh-ing into the VM. Use the IP address of your VM as your machine name. Should be base + 3. You can verify your IP address by clicking the internet connection icon in the GUI interface.
- On your local Mac or Windows computer, Open a terminal and type: - ssh <CIT-username>@ssh.cs.dixie.edu - ssh <CIT-username>@<ip address> - ls -l
4. Change your theme
This assignment is a GUI experience.
- Click the `Finder` dots in the lower left hand corner and you will see the `Settings Wheel`. - Select `Appearance`. - Choose Background - HINT - If you click and hold on the top of the task bar it will detach from full screen mode. This will allow you to see more of the window which will then enable you to change the settings on the Lock Screen. - Click buttons and change other stuff too. Experience!
5. Install GVIM
Install a GUI Text Editor
- Click the `Finder` dots in the lower left hand corner and you will see the `search bar`. - Search for gvim and select install. - Right-Click on the gvim icon and choose "Add to Favorites" to put in taskbar.
SCREENSHOT 1: Take a screenshot that includes the Gvim icon in the taskbar and your new beautiful background
6. Add User Joe
Add a new user to your VM
- Click the `Finder` dots in the lower left hand corner and you will see the `Settings Wheel`. - Scroll to the bottom of the left menu and choose `Details`. - In the `Details` menu choose `Users`. - In the top right click on the `Unlock` button. - Click on the `Add User` button. - Leave the account type as `Standard` - Make an account with the username of `joe` and enter a password for `joe` - Click `Add`
To logout as yourself -
- Click the `Power Button` in the Upper Right had corner - Click on your username and choose `Log Out`
SCREENSHOT 2: Log Out and Take a Screenshot of the Login Screen showing Two Users
7. Login as Joe through the desktop login screen
To login as joe
- Select Joe's name - Enter his password - After the profile is loaded - log out again.
This first login is important because it sets up his account profile, including all the default files and folders.
7a. SSH into your new machine as Joe from scratch
Open up a terminal on your local Mac or Windows machine. NOT in the new Linux Virtual Machine.
ssh to your new VM as joe.
To ssh into your new WM - use the IP address (base +3) as your machine name (You should have written this on your worksheet). And joe as the user.
- ssh <CIT-username>@ssh.cs.dixie.edu - ssh joe@<ip address> - run the `ls -la` command
SCREENSHOT 3: ssh into your VM as joe. Take a screen shot of the ls -al command.
After you are done - properly shutdown your machine using the GUI shutdown. And then Pressing the Red Off Button in vm.cs.dixie.edu. Leave your machine off until you need it again to save resources for other students.
To pass off
Submit your 3 screenshots in Canvas
