DESCRIPTION
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 Solaris 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 stan-
dard 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 nist-
bladm(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 speci-
fied 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 than 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 is 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 direc-
tory on the local machine. Note that ypdomain is case sen-
sitive. 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
-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.
-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 individu-
ally. 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
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 perfor-
mance, unless there are a large number of changes.
-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.
-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.
-v Verbose.
-f file Specify that file should be used as the source of
input (instead of the standard input).
-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.
-Y map Use the dbm files for map as the source of input.
-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.
-P Follow concatenation path. This option specifies
that lookups should follow the concatenation path
of a table if the initial search is unsuccessful.
-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.
-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.
-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 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---.
EXIT CODES
This command returns 0 on success and 1 on failure.
EXAMPLES
This example adds the contents of /etc/passwd to the
passwd.org_dir table.
example% cat /etc/passwd | nisaddent passwd
The next example adds the shadow information; note that the
table type here is "shadow", not "passwd", even though the
actual information is stored in the passwd table.
example% cat /etc/shadow | nisaddent shadow
This example replaces the hosts.org_dir table with the con-
tents of /etc/hosts (in verbose mode).
example% nisaddent -rv -f /etc/hosts hosts
This example merges the passwd map from yypdomain with the
passwd.org_dir.nisdomain table (in verbose mode). The exam-
ple assumes that the /var/yp/myypdomain directory contains
the yppasswd map.
example% nisaddent -mv -y myypdomain passwd nisdomain
This example merges the auto.master map from myypdomain with
the auto_master.org_dir table.
example% nisaddent -m -y myypdomain -Y auto.master \
-t auto_master.org_dir key-value
This example dumps the hosts.org_dir table.
example% nisaddent -d hosts
ENVIRONMENT
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 nis-
domain nor the table are fully qualified,
each directory specified in NIS_PATH will be
searched until the table is found (see nisde-
faults(1)).
