NETGROUP_MKDB(8)					    BSD System Manager's Manual 					  NETGROUP_MKDB(8)

NAME

     netgroup_mkdb -- generate the netgroup database

SYNOPSIS

     netgroup_mkdb [-o database] [file]

DESCRIPTION

     netgroup_mkdb creates a db(3) database for the specified file.  If no file is specified, then /etc/netgroup is used.  This database is
     installed into /var/db/netgroup.db.  The file must be in the correct format (see netgroup(5)).

     The options are as follows:

     -o database
	     Put the output databases in the named file.

     The databases are used by the C library netgroup routines (see getnetgrent(3)).

     netgroup_mkdb exits zero on success, non-zero on failure.

FILES

     /var/db/netgroup.db       The current netgroup database
     /var/db/netgroup.db.tmp   A temporary file
     /etc/netgroup	       The current netgroup file

SEE ALSO

     db(3), getnetgrent(3), netgroup(5)

BUGS

     Because netgroup_mkdb guarantees not to install a partial destination file it must build a temporary file in the same file system and if suc-
     cessful use rename(2) to install over the destination file.

     If netgroup_mkdb fails it will leave the previous version of the destination file intact.

NAME

       revnetgroup - generate reverse netgroup data

SYNOPSIS

       /usr/lib/yp/revnetgroup [-u | -h]

DESCRIPTION

       Revnetgroup processes the standard input in netgroup(5) format into what is called reverse netgroup form. That is, where the original file
       shows netgroup memberships in terms of which members reside in a particular group, the reverse netgroup format specifies what groups are
       associated with a particular member. This information is used to generate the netgroup.byuser and netgroup.byhosts NIS maps. These reverse
       netgroup maps are used to help speed up netgroup lookups, particularly for the innetgr() library function.

       The revnetgroup command prints its results on the standard output. It is usually called only by /var/yp/Makefile when rebuilding the NIS
       netgroup maps.

OPTIONS

       -u
	   Generate netgroup.byuser output; only username information in the original netgroup file is processed.

       -h
	   Generate netgroup.byhost output; only hostname information in the original netgroup file is processed.

FILES

       /var/yp/Makefile
	   The Makefile to build the NIS databases.

       /etc/netgroup
	   The default netgroup database file. This file is most often found only on the NIS master server.

SEE ALSO

       getnetgrent(3), netgroup(5),
