MAKEFILE.YP(8)		FreeBSD	System Manager's Manual		MAKEFILE.YP(8)

     Makefile.yp -- generate and distribute YP maps

     cd	/var/yp; make

     The Makefile.yp utility generates or updates the YP maps to be served by

     Each YP domain to be served must have its own subdirectory	below /var/yp.
     Use ypinit(8) to set up such subdirectories.  In particular, ypinit(8)
     will copy /var/yp/Makefile.yp into	each new domain	subdirectory.  For
     common configuration changes affecting all	future domains,	edit
     /var/yp/Makefile.yp before	running	ypinit(8).  For	configuration changes
     affecting only one	individual domain, edit	the Makefile in	the respective
     domain subdirectory after running ypinit(8).  Do not edit

     By	default, input data for	generating YP maps is collected	from the /etc
     directory.	 Edit the DIR variable to choose a different source directory.

     To	regenerate all maps for	all domains, run make(1) in /var/yp.  To re-
     generate all maps for one single domain, run make(1) in the respective
     domain subdirectory.  The makedbm(8) utility will be used to create the
     maps in Berkeley DB format, and they will be stored inside	the appropri-
     ate domain	subdirectory.

     Whenever a	YP map has been	updated, it is automatically distributed to
     all slave servers in the respective domain	using the yppush(8) utility.
     To	disable	automatic distribution,	set the	NOPUSH variable	to an arbi-
     trary, non-empty, value.

     By	default, Makefile.yp provides the following make(1) targets:

     passwd	Generates the passwd.byname, passwd.byuid,
		master.passwd.byname, and master.passwd.byuid maps from
		master.passwd(5) for use by getpwent(3).

		The master.passwd.* maps always	contain	complete records in
		master.passwd(5) format, including the encrypted passwords.

		The passwd.* maps follow the reduced passwd(5) format having
		the class, change, and expire fields removed but by default
		the encrypted passwords	are included too.  If the UNSECURE
		variable is changed to be empty, the encrypted passwords are
		replaced by asterisks (`*').  This "secure" mode is compatible
		with OpenBSD and FreeBSD clients.

		The MINUID and MAXUID variables	restrict the range of user IDs
		included into the four passwd maps.  By	default, system	users
		are not	included.

     netgroup	Generates the netgroup,	netgroup.byuser, and netgroup.byhost
		maps from netgroup(5) for use by getnetgrent(3)	and passwd(5).
		Requires the revnetgroup(8) utility.

     group	Generates the group.byname and group.bygid maps	from group(5)
		for use	by getgrent(3).

		The MINGID and MAXGID variables	restrict the range of group
		IDs included into both group maps.  By default,	system groups
		are not	included.

     netid	Generates the netid.byname map from netid(5), passwd(5),
		group(5), and hosts(5) for use by getgrouplist(3).  Falls back
		to master.passwd(5) in case passwd(5) is not available.	 Re-
		quires the mknetid(8) utility.

     hosts	Generates the hosts.byname and hosts.byaddr maps from hosts(5)
		for use	by gethostbyname(3).

		To get ypserv(8) to ask	DNS for	unknown	hosts, set the USEDNS
		variable to -b.

     ethers	Generates the ethers.byaddr and	ethers.byname maps from
		ethers(5) for use by ether_aton(3).

     rpc	Generates the rpc.bynumber map from rpc(5) for use by

     services	Generates the services.byname map from services(5) for use by

     protocols	Generates the protocols.byname and protocols.bynumber maps
		from protocols(5) for use by getprotoent(3).

     aliases	Generates the mail.aliases and mail.byaddr maps	from
		aliases(5).  This target uses both sendmail(8) with the	option
		-bi and	the mkalias(8) utility.

     amd.home	Generates the amd.home map from	the file /etc/amd/amd.home.

     all	Generates all of the above, and	sends a	hangup signal to
		ypserv(8) such that it uses the	new maps.

     In	order to keep additional custom	YP maps	up to date, the	Makefile
     should be extended	to support additional targets.

     /var/yp/Makefile		      Top level	YP Makefile.
     /var/yp/domainname/Makefile      Per domain YP maps Makefile.
     /var/yp/domainname/ypservers.db  Database of hosts	serving	this domain.
     /var/yp/domainname/mapname.db    Database files containing	the YP maps.
     /var/yp/domainname/target.time   Cookies controlling the operation	of

     make(1), dbopen(3), makedbm(8), yp(8), ypinit(8), yppush(8), ypserv(8)

     When NOPUSH is set	and individual maps are	regenerated (as	opposed	to
     all), the hangup signal to	ypserv(8) must be sent manually, or the	new
     maps won't	be used.

     When NOPUSH is unset, maps	are pushed to the master server	on the local
     host too, slowing down Makefile.yp.
