OPS245 Assignment 1

OPS245 Assignment 1

The purpose of OPS245 assignments is to showcase your abilities in the course thus far, and conduct a bit of independent research. Some of what you'll be asked to complete will be familiar to you, while other parts will require you to think a bit and do some light Googling. It's expected you won't have all the answers right away, but you can find them. As a result, unlike labs, your professor cannot provide any help or troubleshooting for your assignment.

This assignment will be completed inside your local c7host virtual machine using additional KVM/QEMU nested VMs. There is a live demo component that must be conducted over Microsoft Teams during class time to successfully submit your work.

Weight: 15% of your overall grade

Due Date: Refer to your section's Blackboard announcements.

Create a new virtual machine

1. Install a new CentOS Minimal VM. (Do not install the GUI version.)
2. The virtual machine name and the internal hostname for the machine must be your Seneca username. (Example: cjohnson30)
3. The regular user created during installation must also be your Seneca username.
4. Ensure LVM is used in your installation partitioning.

The rest of this assignment should be done after the installation is completed successfully.

Package Management

Research the rpm and yum commands to:

1. Verify the integrity of a package using rpm to see if any of its files have been altered since installation. (you will be asked to demonstrate this when your assignment is marked, it doesn't matter which package you choose)
2. Demonstrate the install, run, and removal of any rpm package. This means during the demonstration you will show the download, install, and run of any rpm-based package, after doing so show the removal of that package proving that previously installed rpm package is no longer available after removal.
3. Add the EPEL repository to the yum configuration.

Alternate Software Installation

Review the yum group* commands and use them to:

1. Find and install the Cinnamon desktop environment. Feel free to use the power of Google.
2. Do the rest of the assignment (including the assignment submission) while running Cinnamon. (Hint: Think about default targets.)

Lab 3 contains practice in compiling source code. It is recommended you refer to these procedures for compiling and installing software from source code and use them to:

1. Download and extract the source code for ISO Master.
2. Compile and install it (you will need gtk2-devel installed).
3. Run it and have a look at the Help/About dialog box. You will have to change the contents of that box.
4. Edit the file about.c in the source you use earlier, and change "An application for editing ISO9660 images based on the bkisofs access library and the GTK2 GUI toolkit." to "An application used by YOURNAME for OPS245 Assignment 1, Summer 2021".
5. Compile and install the application again, exactly the same way you did the first time. Your change should be simple enough that complicated bugs are unlikely.
6. Check that your changes appear in the application.

Install a Second Linux Distribution as a Virtual Machine

• Create another virtual machine.
• The virtual machine name and the hostname for the machine must be your learn user ID followed by -mint. For example asmith15-mint
• Install Linux Mint as the OS for the new virtual machine.

Submission

This submission requires a live demonstration of your completed assignment during our online class in Microsoft Teams. When you're ready for Assignment 1 to be marked and your professor calls for demos, you'll use the Raise Hand function in Teams to signal you'd like to conduct your demonstration. When it's your turn, you will share your screen using Teams and run through the demo as described below.

Students that do not have a fully completed assignment and ALL required information at the time of your demo will automatically lose 20% of your grade for the assignment. Assignments submitted after your section's due date will receive a grade of 0, but must still be completed satisfactorily in order to pass the course.

Ready to show: Open multiple terminal windows having run the commands necessary to show all the required items in the rubric below. You can switch windows and virtual machines while demonstrating your assignment, but you should not need to run any commands you don't have ready.
