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: # push Ctrl + D key 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...
