=OPS235 Assignment #1 -- Summer 2010=

Weight: 5% of the overall grade<br>
Due Date:  Last week before study week.<br>
(Check with your Professor for exact date)<br>
Due at the start of class.

{{Admon/important | Very Important! | Before making any changes to your system configuration, backup the original configuration files into the <code>/backups</code> directory.}}

==Basic Chores==

'''Complete the following tasks on your system (4 points for each completed task).'''
{{Admon/note | Important | To complete the first task you may need to create an additional virtual disk image for the <code>fedora2</code> virtual machine.}}

#Setup your system so that the command <code>mount /assignment</code> -- executed by any user -- will attach the logical volume <code>assign-vol</code> from the volume group called <code>ASSIGNGROUP</code> (minimum 100 MB) to the mountpoint <code>/assignment</code> (The volume should NOT be automatically mounted at boot time) 
#Setup your system login message to say '''The Open Source Community Is Changing The Computing World''' (to be displayed on all virtual consoles after the login prompt)
#Setup your system login banner to say '''Free as in Freedom.''' (User should see this before login to the system)
#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>~/temp</code> '''NOT''' the <code>/tmp</code> directory.
#Setup the bash environment for the user '''root''' so that the prompt includes the current date.

==Finding your way==

'''Research on your Fedora system to come up with sets of commands to accomplish the following tasks :(5 points for each completed task)'''

#Display a list of all the files under the <code>/boot</code> directory and its sub-directories that have been created or modified within the last 4 hours.
#Display a list of all the files under the <code>/etc</code> directory and all its sub-directories that have been created or modified today (since mid-night).
#Display a list of all the files under the <code>/var</code> directory and all its sub-directories that were last modified more than 4 days ago

Put each set of commands in a separate file. Name the file for task (1) as ass1-1, task (2) as ass1-2, etc. It must be possible to run these script files simply by typing their name (set the permissions appropriately).

==To sudo or not to sudo==

'''Study the man page for the <code>sudo</code> command and:'''

#Update sudo's configuration file (using the proper program) to allow 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>lspci</code>
#Create a new user called <code>helper</code> and allow this user to run <code>sudo</code> for the following commands as your learn account: (4 points)
#*<code>head</code>
#*<code>tail</code>


==Package Management==

'''Research the <code>rpm</code> and <code>yum</code> commands to:'''

#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)(4 points)
#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) (4 points)

==Alternate Software Installation==

'''Review the <code>yum group*</code> commands and use them to: (5 points)

#Find and install the XFCE dektop environment discussed in the following article: [http://www.osnews.com/story.php/5478/XFce-4--A-Refreshingly-Solid-Desktop XFCE Review]
#*You will be asked to demonstrate how to switch to this desktop environment and back again without restarting the X server.

'''Create a bash script called <code>/bin/snapshot</code> to record the following information: (6 points)'''
*A list of all recent bad login attempts.
*A list of Logical Volumes, Physical Volumes, and Volume Groups.
*A report of all mounted filesystems, the amount of space used and the amount of space available.
*The information should be appended to the file <code>/var/log/snapshot.txt</code>
