At this point, we have to construct a list of the hosts which will run NIS servers. ns.server-linux.info 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 .
next host to add: ns.server-linux.info
next host to add:
// push Ctrl + D keys

The current list of NIS servers looks like this:

ns.server-linux.info

Is this correct? [y/n: y]
y
// input 'y' and push Enter key

We need a few minutes to build the databases...
