ypmake - rebuild NIS database


cd /var/yp ; make [map]


The file called Makefile in /var/yp is used by make(1S) 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creates dbm databases for any NIS maps that are out-of-date, and then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it is out of date).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 ipnodes and make networks will create
and yppush the ipnodes and network files, $(INETDIR)/ipnodes and

There are four 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; INETDIR, which gives the directory of
the ipnodes source file; and DOM, which is used to construct a domain
other than the master's default domain. The default for DIR is /etc, and
the default for INETDIR is /etc/inet. The default for NOPUSH is the null

Refer to ypfiles(5) and ypserv(8) for an overview of the NIS service.

If a NIS to LDAP (N2L) configuration file, /var/yp/NISLDAPmapping, is
present, the NIS server components run in N2L mode. In N2L mode, the
server components use a new set of map files with an LDAP-prefix, based
on the LDAP DIT. In N2L mode, authoritative NIS information is obtained
from the DIT. The NIS source files and ypmake have no role, and they
should not be used. If ypmake is accidentally run, then the server
components will detect this, and will log a warning message. For
additional information, see ypfiles(5).

The Network Information Service (NIS) was formerly known as Sun Yellow
Pages (YP). The functionality of the two remains the same. Only the name
has changed. The name Yellow Pages is a registered trademark in the
