'''Weight''': 7.5% of the overall grade
'''Due Date (Fall 2019)''': During '''Week 7''' (in class)check with your professor
== Detailed Requirements ==
#Create a clone virtual machine called '''australinea''' from the '''pangaea''' 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 '''australinea''' virtual machine noting the following items below:<ol type="a"><li>This virtual machine will be the '''Master DNS server''' for '''continents.earth.ops'''.</li><li>Only '''antarctica''' will be allowed to obtain zone transfers of this zone.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL virtual machines in the '''continents.earth.ops.''' zone, including resource records for virtual machines that do not currently exist.</li><li>You MUST use the following names for both the forward and reverse zone files in '''/var/named''' directory: '''mydb-for-continents.earth.ops''' and '''mydb-for-172.28.105'''<li><s> Include an '''MX record''' for email sent to the domain to be directed to '''subway.continents.ops'''.</s></li><li>Any machine in the '''continents.earth.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><li>For machines outside the '''continents.earth.ops''' domain, it will only answer queries about machines inside the network. They may not use it to query other machines.</li></ol>
=== Set-up Slave Name Server ('''antarctica''') ===
#Create a clone virtual machine called '''antarctica''' from the '''pangaea''' 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 '''antarctica''' 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 five three days. If the initial attempt fails, then it will attempt every twelve twenty-four hours until it succeeds, or two three weeks have passed.</li><li>This machine will provide '''forward''' and '''reverse''' lookups of ALL machines in the '''continents.earth.ops''' zone, the zone files for which will be obtained from '''australinea.continents.earth.ops'''.</li><li>Only machines within the '''continents.earth.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 ===
=== 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.
