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

NAME
     ypinit -- build and install NIS databases

SYNOPSIS
     ypinit -m [domainname]
     ypinit -s master_server [domainname]
     ypinit -u [domainname]

DESCRIPTION
     The ypinit	utility	is a script which sets up databases on a Network
     Information Service (NIS) master or slave server.

     On	a master server, ypinit	creates	the /var/yp/$DOMAINNAME	directory, the
     /var/yp/ypservers file, and calls /var/yp/Makefile	to create and populate
     an	initial	set of NIS maps.  The maps are created from local source files
     using the yp_mkdb(8) utility.  The	utility	will prompt the	user for a
     list of servers that support the specified	domain;	this list is used to
     populate the ypservers map.

     On	a slave	server,	ypinit creates the /var/yp/$DOMAINNAME,	populates it
     with copies of the	NIS maps from the master.  The maps are	obtained from
     the master	using the ypxfr(8) utility.  The ypinit	utility	obtains	the
     list of maps to transfer in one of	two ways: if the system	is configured
     as	an NIS client and is bound to the master server, ypinit	is able	to use
     the ypwhich(1) utility to obtain a	list of	maps exported by the master
     server.  If the system is not configured as a client of the NIS master,
     ypinit uses a hardcoded list of maps, some	of which may or	may not	actu-
     ally exist	on the master.	The system administrator can edit the ypinit
     script and	modify the map list if necessary.  Otherwise, individual maps
     can be transferred	manually from the master using ypxfr(8).

OPTIONS
     The ypinit	utility	supports the following options:

     -m	[domainname]
	     Set up a master server.  By default, ypinit sets up a server for
	     the system	default	domain.	 The user can override this default by
	     specifying	domainname explicitly.	Maps are constructed from
	     scratch using local files as templates using the yp_mkdb(8) util-
	     ity.

     -s	master_server [domainname]
	     Set up a slave server using master_name as	the master.  Maps are
	     copied from master_server to the slave using ypxfr(8).  By
	     default, ypinit sets up a server for the system default domain.
	     The user can override this	default	by specifying domainname
	     explicitly.

     -u	[domainname]
	     Update the	ypservers map on the master server.  When a new	slave
	     server is added to	a domain, its hostname must be added to	the
	     ypservers map so that yppush(8) can propagate updates on the mas-
	     ter to all	of the slaves.
