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.
Instructions for online labs
To copy files to your local machine,
Start a new terminal on your home computer (MacOS or Linux) and use the following commands to create a directory called resources.
cd ~/Desktop
mkdir resources
Use the following command to copy files from the CS lab machines to your home computer:
scp -r your_university_account_name@hextreme.otago.ac.nz:/home/coursework/301/resources ~/Desktop/resources
If you use Windows, similarly you should create a folder called resources in your Desktop folder and then use the following command in a command window of Windows (assuming you have Putty installed and make sure you restart Windows after the installation of Putty):
pscp -r your_university_account_name@hextreme.otago.ac.nz:/home/coursework/301/resources c:\Users\your_windows_account_name\Desktop\resources
After these steps, you should be able to do the labs with VirtualBox on your own computer.
