In this assignment, you will use the '''335assign virtual network''' and the '''seedling''' cloning-source that you created in assignment 1 (part 1) to create two name-servers. One of the cloned VMs (hostname: '''balsam''') will be a '''master ''' name server, and the other VM (hostname: '''spruce''') will be a '''slave ''' name server. You will install and setup the master and slave servers in order to provide various domain name resolutions for existing servers, and for servers that will be created and used in assignment #2. 

'''Due Date''': During '''Week 9 ''' (in class) 

#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 Include an '''MX record''' for your admin e-mail contact: email sent to the domain to be directed to '''yoursenecaid@pine.coniferous.trees.ops'''.</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>

#Setup a DNS server on your '''spuce''' 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>

::'''Peter Callaghan's Classes (Sections C &amp; D):'''<ul><li>Refer to instruction on Instructions will be provided through Moodle to download and run marking shell script.</li></ul>

::'''Murray Saul's Classes (Sections A &amp; 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 NOTE: Checking script is currently unavailable</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.

'''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><li>SELinux must be set to '''Enforcing'''.</li><ol>
