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: master next host to add: # push Ctrl + D key The current list of NIS servers looks like this: master Is this correct? [y/n: y] y # answer yes We need a few minutes to build the databases... Building /var/yp/srv.world/ypservers...
