Changes

Describe how to set up (configure) a slave NIS server. 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 pull the configuration data from ALL the servers (Primary DNS and master NIS on the host, secondary DNS on VM1, and slave NIS server on VM2). 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>-host-conf-bu.tar on your host, <date>-vm1-conf-bu.tar on VM1, and <date>-vm2-conf-bu.tar on VM2. Create a separate directory for each day's backup file.
