== Purpose ==
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: '''elmbalsam''') will be a master name server, and the other VM (hostname: '''birchspruce''') 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 ==
'''Due Date''': During Week 9 (in class)
== Detailed Requirements ==
=== Set-up Master Name Server ('''elmbalsam''')=== Perform the following steps for this section: #Create a clone virtual machine called '''balsam''' 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 '''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 Name Server ('''spruce''')===
Perform the following steps for this section:
#Clone the Create a clone virtual machine called '''elmspruce''' virtual machine 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 elm '''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, including resource records the zone files for virtual which will be obtained from '''balsam.coniferous.trees.ops'''.</li><li>Only machines that do not currently exist, but within the '''coniferous.trees.ops''' domain will exist when you perform your assignment #2be allowed to query this machine.</li><li>For This machine will not provide recursive lookup capabilities for any query machines.<br><br></li></ol> === Network Configuration === As you will now have functioning primary and secondary DNS servers, modify your network configuration file on these machines and on the cloning source to specify the correct IPADDR. === Table of Virtual Machines / DNS Records === '''All''' the machines in the following table require DNS records. The rows not shaded represent future servers that will be created in Assignment #2. {| class="wikitable" | style="margin-left:0px;"! Hostname !! Address !!
