Linux and CentOS7

Discussion Lab

1. Setup a BIND DNS server on both VMs. Make sure you setup replication between both servers. Use your CentOS1 server as the master and make CentOS2 the slave.

2. Create entries for both of your virtual machines on the primary DNS server, make sure you create separate zones for the different networks (host only and NAT). Ie. pinging centos1.hostonly results in a different IP than pinging centos1.nat.

3. Verify that replication occurs and explain the process in your writeup as well as include a screenshot as proof.

4. Insert screenshots of each ping test in your lab report.

5. Insert screenshots of you using the nslookup tool to query the server for the new local DNS entries.

6. Also create entries for your default gateway on the NAT network and your host address on the host only network (X.X.X.1).

7. Provide the same verification and proof as above.

8. Both of your VMs should be set to use the new DNS servers for both internal and external address resolution. In this case you will have a primary and secondary DNS server that your internal clients will use to resolve Internet addresses as well as internal addresses. The servers should also provide DNS caching benifits for local users that are attempting to resolve a previously requested Internet address. (ie. www.google.com).

9. Insert screenshots of you using the nslookup utility on one of your VMs against a few FQDNs (ie. www.google.com) to prove that your DNS server is responding to the internal clients queries.

Not looking for said screenshots or anything like that...just looking for assistance in finding the commands needed to complete the tasks myself. I have a decent start, but I'm running out of online resources. Thanks!
