{{Admon/important|This is NOT Assignment 1 Part 1!|This is the '''ROUGH WORK''' for Murray Saul's section for OPS335 Assignment 1 - Part 1. These assignment specifications are NOT complete. Once the assignment specifications are ready, then a link will appear in the [https://wiki.cdot.senecacollege.ca/wiki/OPS335 Main OPS335 WIKI] .}}

== Purpose ==

In For this portion of assignment 1, you will set up the basic functionality for a virtual machine to act as a '''cloning-source''' to make it easier for the student to create other servers (VMs) in later assignments. Whenever you clone another server (in later assignments), you MUST make certain to configure the cloned server in order to make it function in the network correctly and meet the requirements of future assignments. All of the assignments for this course are '''interdependent''' of each other and belong to the same Virtual Private Network called '''335assign'''.

== General Requirements ==

* Assign a newly-created virtual network the name: '''335assign''', and set '''forwarding to any physical device''' (refer to [http://zenit.senecac.on.ca/wiki/index.php/OPS335_Installation_Lab#INVESTIGATION_2:_VIRTUAL_MACHINE_INSTALLATION lab setup]. You can have have 2 different network names: "335assign" and "ops335" without causing any problems).

* Addresses in this network will start with '''~~164~~172.30.20'''. The subnet mask must be '''255.255.255.0'''

* There must '''NOT''' be a DHCP server running for this network!

* All the machines for this assignment will be connected to your newly-created virtual network called: '''335assign'''

=== Create a "Cloning-Source" VM (335assign Virtual Network) ===

Create a virtual machine that you will use as a ~~template (i.e. '''~~cloning-source~~'''). It should have a command-line interface only~~. ~~Configure it to be a good cloning-source, making certain it has all the following elements prior to cloning:~~

Details for the cloning-source #The name of this cloning-source VM will be called: '''seedling'''.#You should use the options that you used in your lab1 to setup the static network, plus you should use the DOMAIN parameter to set the '''coniferous.trees.ops''' domain for your cloning-source.# The VM should have a command-line interface only.#Configure it to be a good cloning-source, '''making certain that the cloning-source has all the following elements prior to cloning:'''::*Don't make the virtual drive too big: you will need space for it as well as space for the clones you from your cloning-source ('''2GB''' should be enough for any cloning-source and clone VM that you create for this assignment).# ::*The hostname for this server will be called: '''~~cloning-source~~seedling'''# ::*Make certain that you can login to your cloning-source.# ::*Configure your network interface for this cloning-source with a '''static''' configuration and is connected to the '''335assign''' network. Refer to the table below for IP address and hostname.

<ol><li value="5"~~>You should use the options that you used in your lab1 to setup the static network, plus you should use the DOMAIN parameter to set the '''ops335.org''' domain for your cloning-source.</li><li~~> Make certain your cloning-source can connect to the Internet using the newer static configuration.</li><li>Run a '''yum update''' for this cloning-source.</li><li>Make certain that SELinux is set to '''enforcing'''.</li><li>Set up an SSH server on this "cloning-source".</li><li> Make sure that '''PermitRootLogin''' is set to '''yes''' for this server. ~~Also make sure~~ </li><li>Make ceratin that only the root account is permitted to login using key authentication. If other users are required to be created in a later assignment, they should be permitted to log in with a their username and password.</li><li>Copy the same public key (already generated for your '''Host Machine''' for your '''root''' account in lab1) to the '''root''' account on your cloning-source.</li><li>Test to make certain that you can login from root on your host machine to your root account on the cloning-course (~~hostname:~~ "seedling") ~~using the '''root''' account~~without being prompted for a pass-phrase.</li><li>If you have created a '''regular user''' when you installed this machine, '''delete that regular user''' (make certain to '''remove the regular user's home directory!'''~~).</li><li>Make sure you can log in from your '''root account''' on your '''Host Machine''' to the '''root account''' on the '''cloning-source''' virtual machine (without a pass-phrase~~).</li></ol>

=== Set-up Firewall Rules for your Cloning-Source===

# Make certain that you have '''iptables''' services enabled and running instead of ''Firewalld''.

# Modify the iptables to meet the following conditions:::<ul>::<li>All outgoing traffic is allowed.</li>::<li>Responses to any traffic the machine sends out are allowed.</li>::<li>Traffic on the loopback interface is allowed.</li>::<li>The ~~default iptables rules should~~ host machine (and only the host machine) must be ~~OK, so you are NOT required~~ able to ssh to ~~make any iptables rules for~~ that cloning-source VM.</li>::<li>ICMP traffic is allowed if it originated with the local network only.</li>::<li>As this ~~portion of~~ is acting as the ~~assignment~~secure basis for later machines, no other traffic should be allowed.</li>::</ul>

=== Create Full and Incremental Backups of cloning-source VM===

*'''Demonstrate working assignment to your instructor in class:'''<ol type="a"><li>Students need to demonstrate their assignment functionality to their professor during a lab period (like you would for any lab for "sign-off").</li><li>Students are required to prepare everything ahead of time so that you can quickly demonstrate to your instructor that all required parts of your assignment are working.</li><li>Do do proceed to the next step until you have demonstrated your assignment to your instructor to check for errors that may cause problems when running the checking script. </li></ol>

*~~'''~~Download and run a shell script ~~that will~~ to check your ~~set-up~~work (Depending on your OPS335 Instructor): ::'''Peter Callaghan's Classes (Sections C & D):'''<ul><li>Refer to instruction on Moodle to download and run marking shell script</li></ul> ::'''Murray Saul's Classes (Sections A & B):'''<ol ~~type="a"~~><li>Login as '''root''' on your '''host''' machine.</li><li>Change to the '''/root/bin''' directory.</li><li>Make certain that your '''cloning-source VM is running'''.<li>Issue the following command to install e-mail on your '''host''' machine:<source>yum install mailx </source><li>Issue the command to download a checking script for your assignment to your '''host''' machine: <source>wget http://matrix.senecac.on.ca/~murray.saul/ops335/check-assn1-p1.bash</source></li><li>Set execute permissions and run the command: '''/root/bin/check-assn1-p1.bash''' (You shell script contents will be mailed to your Seneca email and to your OPS335 instructor's Seneca email. If you do '''NOT''' receive an e-mail message in your Seneca email account, then there is a problem, and you '''MUST''' rerun or contact your OPS335 instructor immediately. </li></ol>

*'''Additional Assignment Information:'''<ol type="a"><li>This assignment is to be completed individually. '''Group submissions are not allowed'''.</li><li>Test your machine to make sure it works. If a machine is not accessible (e.g. will not boot, can not be accessed through ssh from your host, etc.), or is otherwise non-functional, you may be told to '''resubmit'''.</li><li>'''Late submissions are a subject to a penalty of 10% per day'''.</li><ol>
