|

|
||
|
|

|
||
|
|
.Nm yp_mkdb
|
||
|
|

|
||
|
|

||

||
|
|
.Sh DESCRIPTION
|
||
|
|
.Nm yp_mkdb
|
||
|
|
creates
|
||
|
|
.Xr db 3
|
||
|
|
style databases for use with FreeBSD's NIS server.
|
||
|
|
.Nm yp_mkdb
|
||
|
|
reads data from
|
||
|
|
.Nm inputfile ,
|
||
|
|
and writes it to
|
||
|
|
.Nm dbname
|
||
|
|
in
|
||
|
|
.Xr db 3
|
||
|
|
format (using the hash table method).
|
||
|
|
The input should be in 'key data' format, which is to say
|
||
|
|
two fields of ASCII data separated by white space. The first field
|
||
|
|
is assumed to be the key, and everything else is assumed to be
|
||
|
|
the data.
|
||
|
|
These databases are typically stored in
|
||
|
|
.Nm /var/yp/[domainname]
|
||
|
|
where
|
||
|
|
.Nm domainname
|
||
|
|
is the name of the NIS domain being served.
|
||
|
|
.Nm yp_mkdb
|
||
|
|
is usually invoked by
|
||
|
|
.Nm /var/yp/Makefile.
|
||
|
|
.Nm yp_mkdb
|
||
|
|
can also be used to dump an NIS database file so that its
|
||
|
|
contents can be examined. For security reasons, all databases that
|
||
|
|
.Nm yp_mkdb
|
||
|
|
creates are readable and writable by owner only (and usually the
|
||
|
|
owner is root).
|
||
|
|
.Sh OPTIONS
|
||
|
|
The
|
||
|
|
.Nm yp_mkdb
|
||
|
|
command supports the following flags and options:
|
||
|
|
.Bl -tag -width flag
|
||
|
|
.It Fl c
|
||
|
|
Causes
|
||
|
|
.Nm yp_mkdb
|
||
|
|
to send a YPPROC_CLEAR request to
|
||
|
|
.Xr ypserv 8
|
||
|
|
on the local host. This signal tells the server to close any open
|
||
|
|
database descriptors and flush out its database cache. If used alone,
|
||
|
|
this flag signals the server and does nothing else. If used as part
|
||
|
|
of a database creation command,
|
||
|
|
.Nm yp_mkdb
|
||
|
|
will send the signal only after the new database has been successfully
|
||
|
|
created.
|
||
|
|
.It Fl u Ar dbname
|
||
|
|
.Pp
|
||
|
|
Dump (or 'unwind') an NIS database. This option can be used to
|
||
|
|
inspect the contents of an existing NIS database.
|
||
|
|
.It Op Fl i Ar inputfile
|
||
|
|
.Pp
|
||
|
|
When generating an NIS map, encode
|
||
|
|
.Nm inputfile
|
||
|
|
as a special entry in the database with called
|
||
|
|
.Nm YP_INPUT_FILE.
|
||
|
|
.Pp
|
||
|
|
.It Op Fl o Ar outputfile
|
||
|
|
.Pp
|
||
|
|
When generating an NIS map, encode
|
||
|
|
.Nm outputfile
|
||
|
|
as a special entry in the database with called
|
||
|
|
.Nm YP_OUTPUT_FILE .
|
||
|
|
.Pp
|
||
|
|
.It Op Fl m Ar mastername
|
||
|
|
.Pp
|
||
|
|
When generating an NIS map encode
|
||
|
|
.Nm mastername
|
||
|
|
as a special entry in the database with called
|
||
|
|
.Nm YP_MASTER_NAME .
|
||
|
|
This entry in the database is frequently used by various NIS utilities
|
||
|
|
to determine the name of an NIS master server for a domain. By default,
|
||
|
|
.Nm yp_mkdb
|
||
|
|
assumes that the local host is the NIS master; the
|
||
|
|
.Ar m
|
||
|
|
option is used to override this default.
|
||
|
|
.Sh FILES
|
||
|
|
.Bl -tag -width Pa -compact
|
||
|
|
.It Pa /var/yp/Makefile
|
||
|
|
The Makefile that calls
|
||
|
|
.Nm yp_mkdb
|
||
|
|
to build the NIS databases.
