ypmake - rebuild NIS database
cd /var/yp ; make [ map ]
The file called Makefile in /var/yp is used by make(1) to build the
Network Information Service (NIS) database. With no arguments, make
creates dbm databases for any NIS maps that are out-of-date, and then
executes yppush(8) to notify slave databases that there has been a
If you supply a map on the command line, make will update that map
only. Typing make passwd will create and yppush the password database
(assuming it is out of date). Likewise, make hosts and make networks
will create and yppush the host and network files, /etc/hosts and
There are three special variables used by make: DIR, which gives the
directory of the source files; NOPUSH, which when non-null inhibits
doing a yppush of the new database files; and DOM, used to construct a
domain other than the master's default domain. The default for DIR is
/etc, and the default for NOPUSH is the null string.
Refer to ypfiles(5) and ypserv(8) for an overview of the NIS service.
