.I Ypinit
sets up a yellow pages (YP) server's database.
It can be used to set up a master server or a slave server.
You must be the superuser to run it.
It asks a few questions, which are self-explanatory,
and reports success or failure to the terminal.
.PP
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
by changing the information in the YP map named
.IR ypmaps .
All databases are built from scratch,
either from information available to the program at runtime,
or from the ASCII data base files in
.IR /etc .
The list of which files will be used to generate the databases
is below in the FILES section.
All of these files should be in their traditional form,
rather than the abbreviated form used on client machines,
which primarily use the YP services to access the same information.
.PP
A slave YP server database is set up by copying
an existing database from a running server.
The
.I master_name
argument should be the host name of YP server,
which is either actually the master server for all the maps,
or a server the data base of which is believed to be up-to-date and stable.
If your network uses different server machines
acting as the master of different maps,
of course no single machine will be
the master of all maps.
This doesn't matter;
the yp data bases will converge automatically in time,
and the process can be sped up somewhat by using
.IR yppush (8) 
and 
.IR yppull (8).
Just choose a YP server which is up, reachable, and stable.
