NAME    [Toc]    [Back]

     ypmake - rebuild and distribute NIS databases

SYNOPSIS    [Toc]    [Back]

     /var/yp/ypmake [ [	make-options ] map ]

DESCRIPTION    [Toc]    [Back]

     On	NIS master machines, ypmake uses the file /var/yp/mdbm_parse and the
     optional file /var/yp/local.make.script to	build the network information
     service (NIS) databases.  With no arguments, ypmake creates mdbm(3B)
     databases for any NIS maps	that are out-of-date and then executes
     yppush(1M)	to notify slave	servers	that there has been a change.

     If	invoked	with map, ypmake updates that map only.	 Typing	ypmake passwd
     creates and yppushes the password database	(assuming it is	out-of-date).
     Likewise, ypmake hosts and	ypmake networks	create databases from the host
     and network files,	/etc/hosts and /etc/networks, and yppush the databases
     to	the slave servers.  With the -u	option,	ypmake always creates the map.

     cron(1M) executes ypmake at regular intervals in order to maintain
     consistency between NIS servers' databases.  Once a day, ypmake moves the
     log file /var/yp/ypmake.log to /var/yp/ypmake.log.old to keep it from
     growing too large.

     ypmake reads the file /etc/config/ypmaster.options	so that	users can
     specify arguments to mdbm_parse.

     DIR  The directory	of the source files.  (Default is /etc.)

     DOM  Used to construct a domain other than	the master's default domain.

     NOPUSH    [Toc]    [Back]
	  When non-null, inhibits doing	a yppush of the	new database files.
	  (Default is the null string.)

     PWFILE    [Toc]    [Back]
	  full pathname	of the password	file used to build the passwd
	  database.  (Default is /etc/passwd.)

     For instance, to change the location of the password file used by ypmake
     to	/etc/passwd.yp,	include:

	  PWFILE=/etc/passwd.yp

     in	/etc/config/ypmaster.options.  The variables can also be specified as
     arguments on the ypmake command line.

     To	have local NIS maps updated by ypmake, create the file
     /var/yp/local.make.script and add rules similar to	the ones in
     mdbm_parse.

EXAMPLES    [Toc]    [Back]

     To	create and push	the hosts map only it's	out-of-date:

	  ypmake hosts

     To	always create and push the hosts and passwd map:

	  ypmake -u hosts passwd

     To	always create but not push the aliases map:

	  ypmake -u NOPUSH=1 aliases

FILES    [Toc]    [Back]

     /var/yp/make.script
     /var/yp/local.make.script
     /var/yp/mdbm_parse
     /var/yp/ypmake.log
     /var/yp/ypmake.log.old

SEE ALSO    [Toc]    [Back]

     cron(1M), make(1),	makemdbm(1M), ypserv(1M).

NOTE    [Toc]    [Back]

     The mdbm_parse script supports building a database	for the	shadow
     passwords,	but this database is not built by default.  Ypmake must	be
     explicitly	called with a shadow map name argument.

     If	support	for new	databases are added a line must	be added to the	file
     /var/ns/domains/DOMAIN/nsswitch.conf for the NIS domain in	question for
     the server	to allow queries to the	map.
