#Setup a DNS server on your '''balsam''' virtual machine with noting the following items below:<ol type="a"><li>This virtual machine will be the '''Master DNS server'''.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''coniferous.trees.ops''' zone, including resource records for virtual machines that do not currently exist.</li><li> Make certain to include an '''MX record''' for your admin e-mail contact: '''yoursenecaid@coniferous.trees.ops'''</li><li>This machine will allow other machines (outside the '''coniferous.trees.ops.''' zone) to perform DNS lookups among ALL virtual machines within the '''coniferous.trees.ops''' network.</li><li>Any machine in the '''coniferous.trees.ops''' network may use this machine to perform queries of machines outside the network, however it will route all such queries through the DNS server you created in lab #3.</li></ol>
=== Set-up slave Slave Name Server ('''spruce''') ===
Perform the following steps for this section:
#Create a clone virtual machine called '''spruce''' from the '''seedling''' cloning-source. Refer to the table below for '''address''' and '''hostname'''.
#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.
#Setup a DNS server on your '''balsamspuce''' virtual machine with noting the following items below:<ol type="a"><li>This virtual machine will be the '''Slave DNS server''' (in case the Master Name Server goes down).</li><li>This virtual machine will obtain its zone files by copying them from the Master Name Server.</li><li>This Slave DNS server will check for updated records from the Master DNS server every day. If the initial attempt fails, then it will attempt every hour until it succeeds.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''coniferous.trees.ops''' zone, the zone files for which will be obtained from '''balsam.coniferous.trees.ops'''.</li><li>Only machines within the '''coniferous.trees.ops''' domain will be allowed to query this machine.</li><li>This machine will not provide recursive lookup capabilities for any machines.<br><br></li></ol>
=== Network Configuration ===
| '''balsam.coniferous.trees.ops''' || ''' 172.30.20.2''' || '''Master''' Name Server
|-style="background-color:#66cccc;"
| '''spruce.coniferous.trees.ops''' || '''172.30.20.3''' || '''Slave''' Name Server
|- style="background-color:white;"
In addition to the basic firewall established in assignment 1, ensure the following restrictions are met:
# Any machine may query '''balsam'''# Only the machines in the '''coniferous.trees.ops''' network may query spruce.# Only spruce is allowed to get zone transfers from '''balsam'''
== Assignment Submission ==
===Assignment Evaluation Details===
*'''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 <br>(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.<br><br></li></ol>
*Download and run a shell script to check your 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><li>Login as '''root''' on your '''host''' machine.</li><li>Change to the '''/root/bin''' directory.</li><li>Make certain that both your '''balsam''' and '''spruce''' virtual machines are running.<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-p2.bash</source></li><li>Set execute permissions and run the command: '''/root/bin/check-assn1-p2.bash'''<br>(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.<br><br></li></ol>
*'''Additional Assignment Information:'''<ol type="a"><li>This assignment is to be completed individually. '''Group submissions are not allowed'''.</li><li>You are NOT allowed to use local hostname resolution (i.e. no entries in your '''/etc/hosts''' file).<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>
