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".

Assuming you have created myvms and resources folders using the commands in the Lab 1 manual, 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 (make sure you restart Windows after the installation):

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