YPINIT(8)                   System Manager's Manual                  YPINIT(8)



NAME
       ypinit - build and install NIS database

SYNOPSIS
       /usr/etc/yp/ypinit -m

       /usr/etc/yp/ypinit -s master_name

DESCRIPTION
       ypinit  sets  up a Network Information Service (NIS) database on an NIS
       server.  It can be used to set up a master or a slave server.  You must
       be  the  super-user  to run it.  It asks a few, self-explanatory  ques-
       tions, and reports success or failure to the terminal.

       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 NIS system; later if you want you can  change  the  association  of
       maps to masters.

       Note:  If  there  are  both 3.x and 4.x NIS servers running in the net-
              work, the 4.x server should be configured as the master.

       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.

       An NIS 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 an NIS server (either the master server for all  the  maps,
       or a server on which the data base is up-to-date and stable).

       Read ypfiles(5) and ypserv(8) for an overview of the NIS service.

OPTIONS
       -m     Indicate that the local host is to be the NIS master.

       -s     Set up a slave database.

NOTES
       The  Network Information Service (NIS) was formerly known as Sun Yellow
       Pages (YP).  The functionality of the two remains the  same;  only  the
       name  has  changed.  The name Yellow Pages is a registered trademark in
       the United Kingdom of British Telecommunications plc, and  may  not  be
       used without permission.
