ypmake(8)
NAME
  ypmake - rebuild Network Information Service (NIS) database using the make
  command

SYNOPSIS
  cd /var/yp
  make [ options  ] [ map ]

DESCRIPTION
  The make command uses the /var/yp/Makefile file to build an NIS database.
  With no arguments, make creates databases for any NIS maps that are out-
  of-date, and then executes yppush(8) to notify slave servers that there has
  been a change.

				     Note
  Execute the make command only at an NIS master server machine.  If it is
  executed from either a slave server or an NIS client machine, the created
  changes will only be overwritten when the next NIS master server machine
  update, using ypxfr(8), is performed.

FLAGS
  The options argument can be used to override the default values of three
  special variables used by make:

  DIR	    Instructs make to use the source files in the specified
	    directory.	The default is /var/yp/src.

  DOM	    Instructs make to construct a domain other than the master's
	    default domain. The DOM variable in the /var/yp/Makefile file
	    must be set to the domain name before running make. If you run
	    ypsetup, the DOM variable is set when you specify a domain name.

  METHOD    Specifies the database routines used to store NIS maps.  The
	    choices are:

	    b	      btree - Recommended when creating and maintaining very
		      large maps.

	    d	      dbm/ndbm - For backward compatibility. This is the
		      default.

	    h	      hash - A potentially quicker method for managing small
		      maps.

  NOPUSH    When non-null inhibits updating of the new database files using
	    the yppush(8) function. The default is the null string.

  To override the default values of these special variables, an options
  argument format of special_variable = value is used.	See the EXAMPLES
  section for an example.

  The map argument supplied on the command line instructs make to update only
  the specified map.  The specified maps are those located at
  /var/yp/{domain}, where {domain} is the NIS domain name.  Some typical
  entries for the map argument are passwd, hosts, and networks.	 Typing make
  passwd creates and updates the NIS password database, if it is out of date.
  The make command distributes the updated password database to the slave
  servers using yppush(8).  Therefore, typing make host or make networks
  creates and updates the host and network files, /var/yp/src/hosts and
  /var/yp/src/networks, respectively, on the master and slave servers.

  See ypfiles(4) and ypserv(8) for an overview of NIS.

RESTRICTIONS
  You must use the same database format for each map in a domain. In
  addition, a server serving multiple NIS domains must use the same database
  format for all domains.

  Although a Digital UNIX NIS server that takes advantage of btree files will
  be able to store very large maps, NIS slave servers that lack this feature
  might have a much smaller limit on the number of map entries they can
  handle.  It may not be possible to distribute very large maps from a
  Digital UNIX NIS master server to a slave server that lacks support for
  very large maps.  NIS clients are not affected by these enhancements.

EXAMPLES
  This example causes make to create a password NIS map for the domain
  NewDomain instead of for the default domain:

       make DOM=NewDomain passwd
