of Sun Microsystem,it is Domain controller server, it
controls all network users login by a domain, there are two
types of NIS Server

slave will provide user information for network login. In
this case we should not reboot or ShutDown their NIS slave
until the master server up.

ex: /sales 192.168.1.0/255.255.255.0(rw,sync)
that means share the file across the network than save and
