In this course we will primarily working with [http://www.ubuntu.com/ Ubuntu], a widely-used family of Linux distributions. We will be using its [http://www.lubuntu.net/ Lubuntu] variant in Virtualbox earlier in the term; later on we will transition to using Ubuntu Server on the SCS's [http://openstack.scs.carleton.ca/ Openstack installation] (accessible only from the Carleton network).
In this course we will primarily working with [http://www.ubuntu.com/ Ubuntu], a widely-used family of Linux distributions.   We will be using Ubuntu Server on the SCS's [http://openstack.scs.carleton.ca/ Openstack installation] (accessible only from the Carleton network).
 
You may use other Linux distributions to complete the assigned work and do your project; there will be differences, however, in some aspects (such as installing software), particularly if you use a distribution not based on Ubuntu or Debian.
 
===Using Virtualbox in the labs===
 
In the SCS labs you should be able to run the course VM by starting Virtualbox (listed in the Applications menu) and selecting the COMP 2406/3000 virtual machine image.  After the VM has fully booted you will be automatically logged into the student account; this account has admin privileges and its password is "tneduts!".
 
We highly recommend running your VM in full-screen mode (select from the menu, not by maximizing the window).  Do all of your work inside of the VM; it should be fast enough and you won't have any issues with sharing files or with firewalls/network connectivity.
 
You can save the work you do from the course VM (in the student account) to your SCS account and restore it to any other copy of the class VM (on your machines or in the labs) by running using the following commands:
 
  save3000 <SCS username>
  restore3000 <SCS username>
  compare3000 <SCS username>
 
If you use these commands, '''use them consistently'''.  That means run <tt>restore3000</tt> when you first log in, and run <tt>save3000</tt> just before logging out.  If you don't do this, you will '''erase''' the work that you had done previously when you save.
 
If you forgot to restore and you want to save, try running this:
 
  rsync -a -v --progress ~/ <SCS username>@access.scs.carleton.ca:COMP3000/
 
This is the same as the <tt>save3000</tt> command minus the options (--delete and --force) that deletes files in the destination that don't exist in the source.  As a check, you may want to add the <tt>-n</tt> option to do a dry run.
 
===Running the Virtualbox VM on your own machines===
 
If you want to run the VM appliance on your own system (running essentially any desktop operating system you want), just download the [http://homeostasis.scs.carleton.ca/~soma/VMs/COMP%202406%20&%203000,%20Fall%202015.ova virtual appliance file] and import.  The SHA1 hash of this file is:


    a8a70ec2e1b49699f4de29c872ecec7cee21888f [http://homeostasis.scs.carleton.ca/~soma/VMs/COMP%202406%20&%203000,%20Fall%202015.ova COMP 2406 & 3000, Fall 2015.ova]
You may use other Linux distributions to complete the assigned work; there will be differences, however, in some aspects (such as installing software), particularly if you use a distribution not based on Ubuntu or Debian.


On Windows you can compute this hash for your downloaded file using the command [http://support.microsoft.com/kb/889768 <tt>FCIV -sha1 COMP 2406-3000 Fall 2014.ova</tt>].  If the hash is different from above, your download has been corrupted.

If the application is not VirtualBox, you'll need to:
The instructions and guidelines for contributing notes to the wiki can be [[Contributing:Operating_Systems_(Fall_2017)|found here]].
* Have the VM platform ignore any errors in the structure of the appliance found during the import process;
* Uninstall the VirtualBox guest additions by typing starting a terminal application and running
  sudo apt-get purge virtualbox-guest-x11 virtualbox-guest-utils
* Install your platform's own Linux guest additions, if available.
