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. 

=== Clone "ns1" VM Set-up Master Name Server ('''balsam''')=== 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="Cloning Sourcea" &amp; Perform Setup Tasks><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''') ===

#Create a clone virtual machine called: '''ns1spruce''' from the "'''seedling''' cloning -source" that will act as . Refer to the table below for '''address''' and '''hostname'''.#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''master .#Setup a DNS serveron your '''spuce''' on virtual machine with noting the following items below:<ol type="a"><li>This virtual machine will be the '''asg1netSlave DNS server''' network(in case the Master Name Server goes down). Refer to </li><li>This virtual machine will obtain its zone files by copying them from the table below Master Name Server.</li><li>This Slave DNS server will check for address and hostname.#Make certain that your updated records from the Master DNS server must has all every day. If the records for 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 zone called: '''ops335a1coniferous.trees.orgops''' listed in that tablezone, including records the zone files for which will be obtained from '''balsam.coniferous.trees.ops'''.</li><li>Only machines that do within the '''coniferous.trees.ops''' domain will be allowed to query this machine.</li><li>This machine will not exist as of yetprovide recursive lookup capabilities for any machines. It is important <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 understand that specify the correct IPADDR.  === Table of Virtual Machines / DNS records live independently from Records === '''All''' the machines in the following table require DNS records. The rows not shaded represent future servers that they are will be created in Assignment #2. {| class="wikitable" | style="pointingmargin-left:0px;" to.! Hostname !! Address !!

=== Reference Materials: List of Machines / DNS Records =Evaluation Rubric==

All the machines Here is an evaluation rubric (in the table need DNS records, but only the ones in bold need to form) showing you how you will be existing machines 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.
