=OPS235 Assignment = Create a new virtual machine ==#1 -- Specifications=It doesn't matter whether you use the Fedora Live CD or Installation DVD for this.# The virtual machine name and the hostname for the machine must be your learn user ID.# The regular user you create during installation must also be your learn user ID.# Make sure that LVM is used for your new system, "Use all space" should take care of that.
Weight: 5% The rest of this assignment should be done after the overall gradeinstallation is completed successfully.
Due Date: Week after study week== LVM/fstab ==# Add two more drives to your virtual machine, 1GB each.# Add your new drives to the existing volume group.# Create a new logical volume using all available space in the volume group, call it lv_extra# Create a directory named "extra" in your home directory.# Make a change to your fstab so that lv_extra can be mounted on that new directory when the command "mount /home/youruser/extra" is issued. (Check with # Make sure that the mount command can be issued successfully by your Professor for exact date)regular user. Due # Aso make sure lv_extra is not mounted automatically at the start of classboot.
{{Admon/important|Use the ''Fedora2'' Virtual Machine|Complete all parts of this assignment on your <code>fedora2</code> virtual machine '''except''' for the installation of Linux on a new VM. Before starting your assignment make a backup of your virtual machine following the instructions in lab 3.}}== Package Management ==
{{Admon/important|Backup Your Configuration Files|Before making any changes to your system configuration, backup the original configuration files into Research the <code>rpm</backupscode> and <code>yum</code> directory. The contents of that directory will be considered during marking.}}commands to:
==Basic Chores==# Verify the integrity of a package using <code>rpm</code> to see if any of its files have been altered since installation. (you will be asked to demonstrate this when your assignment is marked)# Add the [http://rpmfusion.org/ rpmfusion.org] repository to the yum configuration. (you will be asked to demonstrate installing a package from the rpmfusion repository when your assignment is marked)
'''Complete the following tasks on your system (4 points for each completed task).'''{{Admon/tip|Adding a Virtual Disk|To complete the first task you may need to create an additional virtual disk image for the <code>fedora2</code> virtual machine.}}== Alternate Software Installation ==
#Setup your system so that Review the command <code>mount /a1</code> -- executed by any user -- will attach the logical volume <code>lv_a1</code> from the volume yum group called <code>ops235*</code> (minimum 100 MB) to the mountpoint <code>/a1</code> (The volume should NOT be automatically mounted at boot time) #Setup your system login banner commands and use them to say '''Free software: Free as in Freedom.''' (the user should see this on text-based virtual consoles before login to the system)#Setup your system login message to say '''Open Source is Changing The Computing World''' (to be displayed on all text-based virtual consoles after a successful login prompt)#Setup your system so that every user has a command alias called <code>deltemp</code> which will delete the contents of a directory called <code>~/tmp</code> ('''NOT''' the main <code>/tmp</code> directory!)#Setup the bash environment for the user '''root''' (and only '''root''') so that the prompt includes the current date.
<!# Find and install the XFCE dektop environment discussed in the following article: [http://www.osnews.com/story.php/5478/XFce-4- ==Finding your way==-A-Refreshingly-Solid-Desktop XFCE Review]# Do the rest of the assignment (including the assignment submission) while running XFCE.
'''Research on your Fedora system Review the procedures for compiling and installing software from source code and use them to:# Download and extract the source code for ISO Master.# Compile and install it (you will need gtk2-devel installed).# Now run it and have a look at the Help/About dialog box. You will have to come up with sets change the contents of commands that box.# Edit the file about.c in the source you use earlier, and change "An application for editing ISO9660 images based on the bkisofs access library and the GTK2 GUI toolkit." to accomplish "An application used by YOURNAME for OPS235 Assignment 1".# Compile and install the application again, exactly the following tasks :(5 points for each completed task)'''same way you did the first time. Your change should be simple enough that complicated bugs are unlikely.

==To sudo or not to sudoSubmission ==
Sudo is a tool which enables specific users '''Due date:''' When you are ready for your assignment #1 to be marked, call over your instructor. Students that do not have ALL required information for instructor to run specific commands as another user mark their assignment #1 will automatically lose 20% of their assignment mark (such as "root"deducted from total assignment mark calculation). In that case you may show me your submission in the second lab that week instead. Assignments submitted after that will receive a grade of 0, but must still be completed satisfactorily in order to pass the course.
'''Study the man page for the <code>sudo</code> command andReady to show:'''open terminal windows having run the commands necessary to show all the required items in the rubric below. It is ok to switch windows and virtual machines while submitting your assignment, but you should not need to run any commands.
#Update sudoIf you have questions about the assignment - please wait until everyone's configuration file (using the proper program) to allow only your Learn account to run <code>sudo</code> for the following commands as <code>root</code>: (8 points)#*<code>mount</code>#*<code>fdisk</code>#*<code>passwd</code>#*<code>lsusb</code>#Create a new user called <code>helper</code> assignment is submitted and allow only this user to run <code>sudo</code> for the following commands as ''ask your'' learn account: (4 points)#*<code>vi</code>#*<code>tail</code>question after that.
{{Admon/note|Bonus Option|Explain the hidden danger of including "vi" in the sudo command list (above). Submit this at the time of in-class marking as a well-written, typed, one-page paper with your name and LearnID at the top of the page.}}== Rubric ==
