DESCRIPTION [Toc] [Back]
nisaddent creates entries in NIS+ tables from their corresponding /etc
files and NIS maps. This operation is customized for each of the
standard tables that are used in the administration of HP-UX systems.
The type argument specifies the type of the data being processed.
Legal values for this type are one of aliases, bootparams, ethers,
group, hosts, netid, netmasks, networks, passwd, protocols, publickey,
rpc, services, shadow, or timezone for the standard tables, or key-
value for a generic two-column (key, value) table. For a site specific
table, which is not of key-value type, one can use nistbladm(1) to
administer it.
The NIS+ tables should have already been created by nistbladm(1),
nissetup(1M), or nisserver(1M).
It is easier to use nispopulate(1M) instead of nisaddent to populate
the system tables.
By default, nisaddent reads from the standard input and adds this data
to the NIS+ table associated with the type specified on the command
line. An alternate NIS+ table may be specified with the -t option.
For type key-value, a table specification is required.
Note that the data type can be different from the table name (-t).
For example, the automounter tables have key-value as the table type.
Although, there is a shadow data type, there is no corresponding
shadow table. Both the shadow and the passwd data are stored in the
passwd table itself.
Files may be processed using the -f option, and NIS version 2 (YP)
maps may be processed using the -y option. The merge option is not
available when reading data from standard input.

When a ypdomain is specified, the nisaddent command takes its input
from the dbm files for the appropriate NIS map (mail.aliases,
bootparams, ethers.byaddr, group.byname, hosts.byaddr, netid.byname,
netmasks.byaddr, networks.byname, passwd.byname, protocols.byname,
publickey.byname, rpc.bynumber, services.byname, or timezone.byname).
An alternate NIS map may be specified with the -Y option. For type
key-value, a map specification is required. The map must be in the
/var/yp/ypdomain directory on the local machine. Note that ypdomain
is case sensitive. ypxfr(1M) can be used to get the NIS maps.
If a nisdomain is specified, nisaddent operates on the NIS+ table in
that NIS+ domain; otherwise the default domain is used.
In terms of performance, loading up the tables is fastest when done
through the dbm files (-y).
Options [Toc] [Back]
-a Add the file or map to the NIS+ table without deleting any
existing entries. This option is the default. Note that
this mode only propagates additions and modifications, not
deletions.
-d Dump the NIS+ table to the standard output in the
appropriate format for the given type. For tables of type
key-value, use niscat(1) instead. To dump the cred table,
dump the publickey and the netid types.
-f file Specify that file should be used as the source of input
(instead of the standard input).
-m Merge the file or map with the NIS+ table. This is the most
efficient way to bring an NIS+ table up to date with a file
or NIS map when there are only a small number of changes.
This option adds entries that are not already in the
database, modifies entries that already exist (if changed),
and deletes any entries that are not in the source. Use the
-m option whenever the database is large and replicated, and
the map being loaded differs only in a few entries. This
option reduces the number of update messages that have to be
sent to the replicas. Also see the -r option.
-p Process the password field when loading password information
from a file. By default, the password field is ignored
because it is usually not valid (the actual password appears
in a shadow file).
-q Dump tables in "quick" mode. The default method for dumping
tables processes each entry individually. For some tables
(e.g., hosts), multiple entries must be combined into a
single line, so extra requests to the server must be made.
In "quick" mode, all of the entries for a table are

nisaddent(1M) nisaddent(1M)
retrieved in one call to the server, so the table can be
dumped more quickly. However, for large tables, there is a
chance that the process will run out of virtual memory and
the table will not be dumped.
-r Replace the file or map in the existing NIS+ table by first
deleting any existing entries, and then add the entries from
the source (/etc files, or NIS+ maps). This option has the
same effect as the -m option. The use of this option is
strongly discouraged due to its adverse impact on
performance, unless there are a large number of changes.
-t table Specify that table should be the NIS+ table for this
operation. This should be a relative name as compared to
your default domain or the domainname if it has been
specified.
-v Verbose.
-y ypdomain
Use the dbm files for the appropriate NIS map, from the NIS
domain ypdomain, as the source of input. The files are
expected to be on the local machine in the /var/yp/ypdomain
directory. If the machine is not an NIS server, use
ypxfr(1M) to get a copy of the dbm files for the appropriate
map.
-A All data. This option specifies that the data within the
table and all of the data in tables in the initial table's
concatenation path be returned.
-D defaults
This option specifies a different set of defaults to be used
during this operation. The defaults string is a series of
tokens separated by colons. These tokens represent the
default values to be used for the generic object properties.
All of the legal tokens are described below.
ttl=time
This token sets the default time to live for objects
that are created by this command. The value time is
specified in the format as defined by the nischttl(1)
command. The default is 12 hours.
owner=ownername
This token specifies that the NIS+ principal ownername
should own the created object. The default for this
value is the principal who is executing the command.
group=groupname
This token specifies that the group groupname should be
Hewlett-Packard Company - 3 - HP-UX 11i Version 2: August 2003
nisaddent(1M) nisaddent(1M)
the group owner for the object that is created. The
default is NULL.
access=rights
This token specifies the set of access rights that are
to be granted for the given object. The value rights is
specified in the format as defined by the nischmod(1)
command. The default is ----rmcdr---r---.
-M Master server only. This option specifies that lookups
should be sent to the master server. This guarantees that
the most up-to-date information is seen at the possible
expense that the master server may be busy, or that it may
be made busy by this operation.
-P Follow concatenation path. This option specifies that
lookups should follow the concatenation path of a table if
the initial search is unsuccessful.
-Y map Use the dbm files for map as the source of input.
EXAMPLES [Toc] [Back]
Add the contents of /etc/passwd to the passwd.org_dir table:
cat /etc/passwd | nisaddent passwd
Add the shadow information (note that the table type here is
shadow,not passwd, even though the actual information is stored in the
passwd table):
cat /etc/shadow | nisaddent shadow
Replace the hosts.org_dir table with the contents of /etc/hosts (in
verbose mode):
nisaddent -rv -f /etc/hosts hosts
Merge the passwd map from myypdomain with the passwd.org_dir.nisdomain
table (in verbose mode) (the example assumes that the
/var/yp/myypdomain directory contains the yppasswd map.):
nisaddent -mv -y myypdomain passwd nisdomain
Merge the auto.master map from myypdomain with the auto_master.org_dir
table:
nisaddent -m -y myypdomain -Y auto.master \
-t auto_master.org_dir key-value
Dump the hosts.org_dir table:

EXTERNAL INFLUENCES [Toc] [Back]
Environment Variables
NIS_DEFAULTS This variable contains a default string that will
override the NIS+ standard defaults. If the -D
switch is used, those values will then override both
the NIS_DEFAULTS variable and the standard defaults.
NIS_PATH If this variable is set, and neither the nisdomain
nor the table is fully qualified, each directory
specified in NIS_PATH will be searched until the
table is found (see nisdefaults(1)).
RETURN VALUE [Toc] [Back]
nisaddent returns 0 on success and 1 on failure.
WARNINGS [Toc] [Back]
HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is
supported.
LDAP is the recommended replacement for NIS+. HP fully supports the
industry standard naming services based on LDAP.
