It sets up a master server using the simple model in which that server is master to all maps in the data base. This is the way to bootstrap the YP system; later if you want you can change the association of maps to masters. All databases are built from scratch, either from information available to the program at runtime, or from the ASCII data base files in /etc. These files are listed below under FILES . All such files should be in their "traditional" form, rather than the abbreviated form used on client machines.
A YP database on a slave server is set up by copying an existing database from a running server. The master_name argument should be the hostname of YP server (either the master server for all the maps, or a server on which the data base is up-to-date and stable).
Refer to ypfiles(5) and ypserv(8) for an overview of the yellow pages.
