Changes

You should have your VM1 configured as the primary DNS server (lab3) and Vm2 configured as the master NIS server (lab 9) by now. In order to provide redundancy, we want to set up a seconday DNS server and a slave NIS server. We also want to backup the configuration files and database files of those servers to a separate machine at a scheduled time.

You are The objective is to develop a procedure for setting up a secondary DNS server on VM3VM2, a slave NIS server on VM1, and a backup server on VM2 VM3 running Fedora 20. The procedure should include test cases to verify that your the correctness and completeness of the set up has been completed correctly. Please The complete procedure should be break down your procedure into the following four three phases:

Describe how '''Due Date: August 4, 2015''' Develop the procedure to set up (setup, configure) , and test a secondary DNS serverfor your domain. You already have your Primary DNS server for your domain up and running on VM1. Your secondary DNS server must comply with the following operation policy:* It should set answers to queries for resource that have no matching record to be valid for 30 minutes.* If it fails to retrieve an update from the primary server, it should try again every 10 minutes.* If it can not contact the primary server for more than 12 hours, it should no longer consider the data it holds to be valid.* If it is not informed of update by the primary server for more than 3 hours, it should contact the primary to determine if there are updates. You may have to mentioned the changes that need to be make on the Primary DNS server to support the proper operation of the secondary DNS server.

'''Due Date: August 7, 2015''' Describe how to set up (setup, configure) , and test a slave NIS serverfor your NIS domain. You may have to mentioned mention the changes that need to be make made to the master NIS server as well.

'''Due Date: August 7, 2015''' Describe how to set up a backup server to <b>pull </b> the configuration data from ALL the servers (Primary DNS and master NIS on the hostserver, secondary DNS on VM1server, master NIS server, and slave NIS server on VM2)and save the files in the directories /backup/pri-dns, /backup/sec-dns, /backup/mas-nis, /backup/sla-nis respectively. You should consider doing the following steps:# run a shell script 1 minute after midnight to package all configuration files and database files into a tar ball file. Name the tar ball file as <date>-hostprimary.tar for all the files for your primary DNS server, <date>-conf-busecondary.tar on for your hostsecondary DNS server, and <date>-vm1-conf-bumaster.tar on VM1for your master NIS server, and <date>-vm2-conf-buslave.tar on VM2. Create a separate directory for each day's backup fileyour slave NIS server.# if Pull the tar ball file is created successfully, create a status file in to the same corresponding directoryon the backup server.# run Create a shell script 1 minute after 1:00am on vm3 transfer each status file in the corresponding backup file on host, VM1, and VM2 directory to VM3 if indicate when the backup tar ball file was created and when it was successfullybackup to the backup server.. Create a separate directory for storing each day's  === Sample Directory Structure on the backup files using server ===The following listing show the date so directory structure on the back ups are sortedbackup server after three successful backups on July 1, July 2, and July 3:<pre>/backup├── mas-nis│ ├── 20150701-bu-status│ ├── 20150701-master.tar│ ├── 20150702-bu-status│ ├── 20150702-master.tar│ ├── 20150703-bu-status│ └── 20150703-master.tar├── pri-dns│ ├── 20150701-bu-status│ ├── 20150701-primary.tar│ ├── 20150702-bu-status│ ├── 20150702-primary.tar│ ├── 20150703-bu-status│ └── 20150703-primary.tar├── sec-dns│ ├── 20150701-bu-status│ ├── 20150701-secondary.tar│ ├── 20150702-bu-status│ ├── 20150702-secondary.tar│ ├── 20150703-bu-status│ └── 20150703-secondary.tar└── sla-nis ├── 20150701-bu-status ├── 20150701-slavs.tar ├── 20150702-bu-status ├── 20150702-slavs.tar ├── 20150703-bu-status └── 20150703-slavs.tar 4 directories, 24 files

Your procedure and test cases should be original, individual work and made so that it can be replicated in Lab S2119 on the PC availablein the lab.

You need to submit a PDF file by both email and hardcopy. The PDF file should contain the entire lab including the answers to lab questions, and the second file is the TXT file containing the questions procedure and answers to all the lab ONLYtest results.
