 === Set-up a Virtual Network (335assign) ===

* Assign a newly-created virtual network the name: '''asg1net335assign''', and set '''forwarding to any physical device'''<br>(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: "asg1net335assign" and "ops335" without causing any problems).* Addresses in this network will start with '''10172.161''' followed by the ''30.20'last two digits of your student number''' (just as your main virtual network). The subnet mask must be '''255.255.255.0'''

* All the machines for this assignment will be connected to your newly-created virtual network called: '''asg1net335assign''' === Create a "Cloning-Source" VM (335assign Virtual Network) === Create a virtual machine that you will use as a cloning-source. 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<br>('''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: '''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.<br>

=== Create a "|-| '''seedling.coniferous.trees.ops''' || '''172.30.20.100''' || '''Cloning Source" VM (asg1net Virtual Network) ===-source''' used to create other servers for other assignments.|}

=== Clone "ns1" VM from "Set-up Firewall Rules for your Cloning -Source" &amp; Perform Setup Tasks===

#Create a clone called: '''ns1''' from the "cloning source" Make certain that will act as your you have '''master DNS serveriptables''' on the ''services enabled and running instead of 'asg1net'Firewalld'' network. Refer to the table below for address and hostname.#Make certain that your DNS server must has all Modify the records for iptables to meet the zone calledfollowing conditions:::<ul>:: '''ops335a1<li>All outgoing traffic is allowed.org''' listed in that table, including records for machines that do not exist as of yet. It is important </li>::<li>Responses to understand that DNS records live independently from any traffic the machines that they machine sends out are "pointing" toallowed.</li>#A default setup for a master DNS server should be sufficient, but make certain that ::<li>Traffic on the address of your '''admin contact''' loopback interface isallowed.</li>:: '''yoursenecaid@ops335a1.org''', <li>The host machine (and <b>only</b> the host machine) must be able to ssh to that slave DNS servers will check cloning-source VM.</li>::<li>ICMP traffic is allowed if it originated with the <b>local network only</b>.</li>::<li>As this is acting as the secure basis for updated records from this master every 30 minuteslater machines, no other traffic should be allowed.</li>::</ul>

== Clone "ns2" = Create Full and Incremental Backups of cloning-source VM from "Cloning Source" &amp; Perform Setup Tasks ===

# This task is to be performed in your '''host''' machine.# Issue the command '''su -'''#Create a clone Bash shell script called '''ns2/root/bin/assnBackup.bash''' to perform a '''full backup''' from using the '''gzip''' command to backup the entire file system of your cloning -source VM to save the compressed copy to the directory path: '''/backup/full/'''). # This shell script should store any VM image file in the "/var/lib/libvirt/images" directory that will act has the extension ".qcow2" as your a positional parameter to be used with a for loop. # Perform a Net-search to use the '''pv'''('slave DNS server'pipe-viewer'' on ) command to show a text-based indicator of backup for EACH VM image file. You need to add the '''asg1netEPEL repository''' network. Refer to install the table below pv command.# Set execute permissions for address this script, and hostnamerun this Bash shell script prior to exiting your assignment work session to properly backup your cloning source. You should also make a copy of the backup on an external device (such as a USB key).#Set-up via a crontab entry, an '''incremental backup''' of the '''/etc/''' directory of your cloning-source to be performed every hour to the '''/backup/incremental/cloning-source''' directory.  == Assignment Submission == The student is required to prove to their professor that their set-up works correctly during the regularly-scheduled lab period.  ===Assignment Evaluation Details=== *'''ns2Demonstrate working assignment to your instructor in class:''' machine will serve <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 same records as checking script.<br><br></li></ol> *Download and run a shell script to check your work (Depending on your OPS335 Instructor):  ::'''Peter Callaghan'ns1s Classes (Sections C &amp; D):'''.<ul><li>Refer to instruction on Moodle to download and run marking shell script</li></ul>

Here is an evaluation rubric (in table form) showing you how you will be evaluated for this assignment.Part of the rubric is marked from professor observation from student demonstration of assignment in class, and the other part is based on output from the results of an assignment checking script that the student will download and run. {| class="wikitable"width=50%|-!
