You are The objective is to develop a procedure for setting up a secondary DNS server on VM2, a slave NIS server on VM1, and a backup server on 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:

Develop the procedure to setup, configure, and test a secondary DNS server for your domain. You already have your Primary DNS server for your domain up and running on VM1. Your secondary DNS server must conform to comply with the following operation pollicypolicy:

* If it can not contact the master 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.

Describe how to set up (setup, configure) , and test a slave NIS serverfor your NIS domain. You may have to mentioned the changes that need to be make to the master NIS server as well.

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 VM2for your slave NIS server. Create a separate Pull the tar ball files to the corresponding directory for each day's on the backup fileserver.# if the tar ball file is created successfully, create Create a status file in the same corresponding backup directory.# run a shell script 1 minute after 1:00am on vm3 transfer each backup file on host, VM1, and VM2 to VM3 if indicate when the backup tar ball file was created and when it was successfully. Create a separate directory for storing each day's backup files using to the date so the back ups are sortedbackup server..
