255.255.255.0   10.0.0.0

127.0.0.1       localhost

10.0.0.30 dlp.srv.world dlp
10.0.0.51 node01.srv.world node01

At this point, we have to construct a list of the hosts which will run NIS
servers.  dlp.srv.world is in the list of NIS server hosts.  Please continue to add
the names for the other hosts, one per line.  When you are done with the
list, type a <control D>.
        next host to add:  dlp.srv.world
        next host to add:  # Ctrl + D キー
The current list of NIS servers looks like this:

dlp.srv.world

Is this correct?  [y/n: y]  y
We need a few minutes to build the databases...

dlp.srv.world has been set up as a NIS master server.

Now you can run ypinit -s dlp.srv.world on all slave server.
