NAME

     mknetid -- generate netid map data

SYNOPSIS

     mknetid [-q] [-g group_file] [-p passwd_file] [-h hosts_file] [-n netid_file] [-d domain]

DESCRIPTION

     The mknetid utility processes the contents of the group(5), passwd(5), hosts(5) and netid(5) files into the format used to generate the
     netid.byname NIS map.  This map is used to hold credential information for both users and hosts in an operating system independent format.

     The mknetid utility checks for duplicate occurrences of netids and filters them out.

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

OPTIONS

     The mknetid utility supports the following options:

     -q      Normally, mknetid prints a warning message when it encounters a duplicate netid.  This flag turns on 'quiet' mode, allowing the warn-
	     ings to be suppressed.  Other error messages may still be generated.

     -g group_file
	     Specify the location of the group information file.  The compiled-in default is /etc/group.

     -p passwd_file
	     Specify the location of the passwd information file.  The compiled-in default is /etc/passwd.

     -h hosts_file
	     Specify the location of the hosts database file.  The compiled-in default is /etc/hosts.

     -n netid_file
	     Specify the location of the netid information file.  The compiled-in default is /etc/netid.  Note that no error is generated if the
	     netid database cannot be found.  The netid database is not likely to be present on most systems until Secure RPC support is added to
	     FreeBSD.

     -d domain
	     By default, the mknetid utility uses the system domainname when generating netid records.	If the system domainname is not set, the
	     domain must be specified on the command line with the -d flag.  If the domainname is set, the -d flag may be used to override it.

FILES

     /var/yp/Makefile  the Makefile that calls yp_mkdb and mknetid to build the NIS databases
     /etc/group        the default group database file
     /etc/passwd       the default passwd database file
     /etc/hosts        the default hosts database file
     /etc/netid        the default netid database file

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

NAME

     revnetgroup -- generate reverse netgroup data

SYNOPSIS

     revnetgroup -u | -h [-f netgroup_file]

DESCRIPTION

     The revnetgroup utility processes the contents of a file 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.byhost NIS maps.
     These reverse netgroup maps are used to help speed up netgroup lookups, particularly for the innetgr() library function.

     For example, the standard /etc/netgroup file may list a netgroup and a list of its members.  Here, the netgroup is considered the key and the
     member names are the data.  By contrast, the reverse netgroup.byuser database lists each unique member as the key and the netgroups to which
     the members belong become the data.  Separate databases are created to hold information pertaining to users and hosts; this allows netgroup
     username lookups and netgroup hostname lookups to be performed using independent keyspaces.

     By constructing these reverse netgroup databases (and the corresponding NIS maps) in advance, the getnetgrent(3) library functions are spared
     from having to work out the dependencies themselves on the fly.  This is important on networks with large numbers of users and hosts, since
     it can take a considerable amount of time to process very large netgroup databases.

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

OPTIONS

     The revnetgroup utility supports the following 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.  (Note at least one of the -u
	     or -h flags must be specified.)

     [-f netgroup_file]
	     The revnetgroup utility uses /etc/netgroup as its default input file.  The -f flag allows the user to specify an alternate input
	     file.  Specifying ``-'' as the input file causes revnetgroup to read from the standard input.

FILES

     /var/yp/Makefile  the Makefile that calls yp_mkdb and revnetgroup to build the NIS databases
     /etc/netgroup     the default netgroup database file.  This file is most often found only on the NIS master server
