about the script:

1. It will set the domain name, which u give
2. NIS alternate directory will be created in /mynis folder

Configuring NIS Master server
-------------------------------
In order for NIS to operate sucessfully, we have to construct a list of the
NIS servers. Please continue to add the names for YP servers in order of
preference, one per line. When you are done with the list, type a <control D>
or a return on a line by itself.
next host to add: indigo
next host to add:

The current list of yp servers looks like this:
indigo
Is this correct? [y/n: y] y
Installing the YP database will require that you answer a few questions.
Questions will all be asked at the beginning of the procedure.
Do you want this procedure to quit on non-fatal errors? [y/n: n] y
The yp domain directory is /var/yp/INDIA
There will be no further questions. The remainder of the procedure should take
5 to 10 minutes.

indigo has been set up as a yp master server without any errors.
If there are running slave yp servers, run yppush now for any data bases
which have been changed. If there are no running slaves, run ypinit on
those hosts which are to be slave servers.
