== 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 '''elmbalsam''' 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 '''elmbalsam''' 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, but will exist when you perform your assignment #2.</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 (i.e. recursive lookups).</li><li>Only Any machine in the '''coniferous.trees.ops''' network may use this Master Name Server machine to perform queries of machines outside the network, however it will be allowed to transfer zone files from this machineroute all such queries through the DNS server you created in lab #3.<br><br></li></ol>#As you will now have a functioning primary DNS server, modify your network configuration file to specify its new IPADDR.
=== Set-up slave Slave Name Server (birch'''spruce''') ===
Perform the following steps for this section:
#Create a clone virtual machine called '''birchspruce''' 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 '''elmspuce''' 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 '''elmbalsam.coniferous.trees.ops'''.</li><li>Only machines within the spiral'''coniferous.galaxiestrees.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 === As you will now have a functioning primary and secondary DNS serverservers, modify your network configuration file on these machines and on the cloning source to specify its new the correct IPADDR. You will also have to add another IPADDR for your DNS server you setup in lab #1 to allow DNS queries from your virtual machines to outside server (TIP: You cannot use your '''primary''' or '''secondary''' DNS option).
=== Reference Materials: List Table of Virtual Machines / DNS Records ===
'''All ''' the machines in the following table need require DNS records. The rows not shaded represent future servers that will be created in Assignment #2.

===Set-up Firewall Policies===
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'''
