The COMP8440 course will use the lab machines in N111. You will need to follow the instructions below to setup your own machine and to regularly backup your machine using the "Backup System" link on your desktop.

## Initial Setup
|
|
|
Each machine in the N115/N116 lab has two additional disk "partitions" with an initial copy of the "master" image for FOSSD 2018, based on the [Ubuntu 17.10 (Artful Aardvark)](http://releases.ubuntu.com/17.10.1/) Linux distribution, and a boot partition.

|
For the first (initial) setup, you will need to log into the machine whilst it is booted in the normal (CSIT) lab environment. That is the default boot environment, which can also selected using the 'net' option during bootup
|
|
|
|
|
|
On your desktop you should see a icon "Setup FOSSD". Double-click that icon.
|
|
|
|
|
|
A new terminal window should appear and you will be prompted for your login password (to allow you "superuser" access).
|
|
|
Open a terminal and type the command "/courses/comp8440/bin/setup_fossd_system". You will be prompted for your login password (to allow you "superuser" access).
|
|
|
|
|
|
Then you will be prompted for a passphrase for the encrypted filesystem, twice. You can press the "Enter" key each time to use the default FOSSD passphrase for the encrypted filesystem (written up on the whiteboard in the lab), or you can make up a new passphrase - but don't forget it! If you forget your passphrase then all your work will be lost, and cannot be recovered.
|
|
|
|
|
|
Then you may be prompted for your login password one last time before the system initialises the partition with the Ubuntu Saucy image we have prepared. As a part of this initialisation, an account will be created for you in this image.

When that is complete, you can reboot your machine and then select "fossd" from the network boot prompt which will boot into the encrypted filesystem. You will be prompted for the passphrase you have chosen for the encrypted filesystem. It is **very** important that you do not forget this passphrase!

You MUST backup your work regularly (using the "Backup System" icon on your desktop) as there is a possibility of hardware failure, software failure, accidental deletion and someone overwriting your encrypted filesystem. You have been warned (again!).

## Technical Information
|
|
|
The course will utilise the N111 19 place lab in the CSIT building. This lab has 40 machines each with 3.2GHz CORE i5 CPUs, 8GB RAM, a 500GB hard disk and a 24" LCD monitor (may be upgraded since last checked). The machines are networked onto a single VLAN with 1Gbps ethernet.

The course will utilise the N111 lab in the CSIT building. This lab has 29 machines each with 3.4GHz CORE i7 CPUs, 16GB RAM, a 256GB SSD and a 24" integrated LCD monitor (may be upgraded since last checked). The machines are networked onto a single VLAN with 1Gbps ethernet.
|
|
|
|
|
|
The machines in the lab are normally used by CS courses with a software image based on Ubuntu Artful Aardvark (17.10) Linux (from October, 2017). The machines are set to "network boot" and obtain their software image from a lab server. This image is not suitable for use by this course as it does not allow students to add their own packages, nor to gain superuser access in normal use.
