COMP3000 Operating Systems 2023F Tutorials

This page contains Tutorial instructions for COMP3000 A, Fall 2023.

The main page for the course can be found here.

Information about the Tutorials

Tutorials are in person. You need to be physically in the room to finish up the tutorial instructions on your laptop and get checked-out by one of the two present TAs. Your TA will be your first point of contact when you have questions or encounter any issues during the tutorial session.

Please stick to the tutorial session you are registered in. This avoids overcrowding.

Make well use of these tutorials to help you better understand the course material. The plan is to have 9 tutorial sessions this term, each would be worth 2.22% of your total grade. We might revisit this as the term progresses.

Getting Access to a Linux Machine

For the tutorials, you need to get access to a Linux machine. It is recommended to use an SCS Openstack instance (see instructions below). Alternatively, if you prefer to work directly on your laptop and avoid Openstack, you can also download this VirtualBox image (courtesy of Prof. Zhao from Winter 2023). You will need access to a Linux system for the entire semester, ideally the same one.

Setting up an Openstack VM instance for the first time

We will use Openstack for the tutorials of this course. Follow these instructions for setting up an Openstack VM instance: instructions here. You only need to do this once for the whole term. Please use the same instance for both: the tutorials and the assignments. No need to create two instances.

Connecting to the VM

You can find instructions with various ways to connect to your Openstack instance here.

Downloading files from the VM

To download files from your Openstack VM instance, you can find instructions here.

Backing up the VM

To backup your VM, the image provides an "scs-backup" command that will backup the student user's directory to the SCS linux machines. So if your SCS username is janedoe, you can type:

scs-backup janedoe

and it will create a copy of everything in the student account's home directory (note: you can customize it) in a directory called "COMP3000VM-backup" in your SCS home directory. You can ssh/sftp to access.scs.carleton.ca in order to access this copy of your VM's files. You should do backups at the end of every session and before you do anything dangerous.

Reminder: do not take snapshots of your instance! Note that you cannot take snapshots of your VM anyway (it will keep trying and never succeed, and you'll create work for the tech staff who will have to undo what you did), so please don't try.
