Final Exam

COSC301 final exam will be replaced by an internal assessment via Blackboard, which will be due on 19th June mid-night. It will be released next Monday (1st June). Details are as below.

Details of COSC301 final exam

About the internal assessment

Considering the current situation, I decided to remove a few assessed labs from the internal assessment. Now you only need to finish the VPN (Lab 20) and Subnetting (Lab 19).

The total marks will be 40 including assignments 1 and 2, but I will scale it to 50.

The due date for Assignment 2 is Thursday 14th May, 3pm.

The due date for the two assessed labs is the last Thursday of the semester, 28th May 3pm.

The marking of the assignment and the assessed labs is through Zoom.

About the SSH lab

Since we can't access vertex.otago.ac.nz from outside of campus, you can use hextreme.otago.ac.nz instead.

VirtualBox Issues

Make sure to download and install "VirtualBox 6.1.4 Oracle VM VirtualBox Extension Pack" from: https://www.virtualbox.org/wiki/Downloads which will enable USB etc.

External DNS server

When you configure DNS server, wherever you use 139.80.64.1 or 139.80.64.3, use 8.8.8.8 instead. This is because now we are moving outside of Otago campus, the Otago DNS server won't work for us for any domain that Otago is not responsible for.

IP addresses

When you configure your virtual machines on the computer at home, use the IP address 192.168.3.x instead of 192.168.1.x.

This is to avoid IP address clash with your home network which usually uses 192.168.1.x.

VirtualBox Installation Instructions

I've only listed those topics relevant to this paper, there are lots more.

To copy files to your local machine,

First, make sure you can login to hextreme.otago.ac.nz with your CS account using "ssh your_account_name@hextreme.otago.ac.nz".

Then you should be able to find your myvms and resources folders from your Desktop directory, using:

cd ~/Desktop

ls myvms

ls resources

Finally, start a new terminal on your home computer (MacOS or Linux) and use the following commands:

scp -r your_account_name@hextreme.otago.ac.nz:Desktop/myvms ~/Desktop/myvms

scp -r your_account_name@hextreme.otago.ac.nz:Desktop/resources ~/Desktop/resources

If you use Windows, use this command in a command window of Windows if you have Putty installed:

pscp -r your_account_name@hextreme.otago.ac.nz:Desktop/myvms c:\Users\your_windows_account_name\Desktop\myvms
