At this point, we have to construct a list of the hosts which will run NIS servers. Server.paching.com.tw is in the list of NIS server hosts. Please continue to addthe names for the other hosts, one per line. When you are done with the list, type a .next host to add: node1 host namenext host to add: Ctrl - DThe current list of NIS servers looks like this: Server.paching.com.twIs this correct? [y/n: y] y y !
