== Purpose ==
In this assignment, you will use the '''335assign virtual network''' and the '''sylvanas''' cloning-source that you created in assignment 1 (part 1) to create two name-servers. One of the cloned VMs (hostname: '''varian''') will be a '''master''' name server, and the other VM (hostname: '''spruceguldan''') 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.
== General Requirements ==
#Setup a DNS server on your '''varian''' virtual machine 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 '''warcraft.games.ops.''' zone, including resource records for virtual machines that do not currently exist.</li><li> Include an '''MX record''' for e-mail email sent to the domain to be directed to '''illidan.warcraft.games.ops'''.</li><li>Any machine in the '''warcraft.games.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 Name Server ('''spruceguldan''') ===
Perform the following steps for this section:
#Create a clone virtual machine called '''spruceguldan''' from the '''sylvanas''' 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 '''spuce''' virtual machine 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 '''warcraft.games.ops''' zone, the zone files for which will be obtained from '''varian.warcraft.games.ops'''.</li><li>Only machines within the '''warcraft.games.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>
# Any machine may query '''varian'''
# Only the machines in the '''warcraft.games.ops''' network may query spruceguldan.# Only spruce guldan is allowed to get zone transfers from '''varian'''
== Assignment Submission ==
::'''Elizabeth Kopiec's Classes (Section A):'''<ol><li>Login as '''root''' on your '''host''' machine.</li><li>Change to the '''/root/bin''' directory.</li><li>Make certain that both your '''varian''' and '''spruceguldan''' 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>
