YPMAKE(8)                   System Manager's Manual                  YPMAKE(8)



NAME
       ypmake - rebuild NIS database

SYNOPSIS
       cd /var/yp ; make [ map ]

DESCRIPTION
       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       creates  dbm  databases for any NIS maps that are out-of-date, and then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
       change.

       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       (assuming  it  is out of date).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
       /etc/networks.

       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.

NOTES
       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 United Kingdom of British Telecommunications plc, and  may  not  be
       used without permission.
