DESCRIPTION
The nispopulate shell script can be used to populate NIS+ tables in a
specified domain from their corresponding files or NIS maps. nispopu‐
late assumes that the tables have been created either through nis‐
server(1M) or nissetup(1M).
The table argument accepts standard names that are used in the adminis‐
tration of Solaris systems and non-standard key-value type tables. See
nisaddent(1M) for more information on key-value type tables. If the ta‐
ble argument is not specified, nispopulate will automatically populate
each of the standard tables. These standard (default) tables are:
auto_master, auto_home, ethers, group, hosts, ipnodes, networks,
passwd, protocols, services, rpc, netmasks, bootparams, netgroup,
aliases and shadow. Note that the shadow table is only used when popu‐
lating from files. The non-standard tables that nispopulate accepts are
those of key-value type. These tables must first be created manually
with the nistbladm(1) command.
Use the first synopsis (-Y) to populate NIS+ tables from NIS maps. nis‐
populate uses ypxfr(1M) to transfer the NIS maps from the NIS servers
to the /var/yp/<NIS_domain> directory on the local machine. Then, it
uses these files as the input source. Note that <NIS_domain> is case
sensitive. Make sure there is enough disk space for that directory.
Use the second synopsis (-F) to populate NIS+ tables from local files.
nispopulate will use those files that match the table name as input
sources in the current working directory or in the specified directory.
Note that when populating the hosts, ipnodes, and passwd tables, nis‐
populate will automatically create the NIS+ credentials for all users
and hosts (ipnodes) that are defined in the hosts, ipnodes, and passwd
tables, respectively. A network passwd is required to create these cre‐
dentials. This network password is used to encrypt the secret key for
the new users and hosts. This password can be specified using the -l
option or it will use the default password, nisplus. nispopulate will
not overwrite any existing credential entries in the credential table.
Use nisclient(1M) to overwrite the entries in the cred table. It cre‐
ates both LOCAL and DES credentials for users, and only DES credentials
for hosts. To disable automatic credential creation, specify the "-S 0"
option.
The third synopsis (-C) is used to populate NIS+ credential table with
level 2 authentication (DES) from the hosts, ipnodes and passwd tables
of the specified domain. The valid table arguments for this operation
are hosts, ipnodes and passwd. If this argument is not specified then
it will use hosts, ipnodes and passwd as the input source. If other
authentication mechanisms are configured using nisauthconf(1M), the
NIS+ credential table will be loaded with credentials for those mecha‐
nisms.
If nispopulate was earlier used with "-S 0" option, then no credentials
were added for the hosts or the users. If later the site decides to add
credentials for all users and hosts, then this (-C) option can be used
to add credentials.
OPTIONS-a <NIS_server_addr> Specifies the IP address for the NIS server.
This option is only used with the -Y option.
-C Populate the NIS+ credential table from hosts,
ipnodes, and passwd tables using DES authenti‐
cation (security level 2). If other authentica‐
tion mechanisms are configured using nisauth‐
conf(1M), the NIS+ credential table will be
populated with credentials for those mecha‐
nisms.
-d <NIS+_domain.> Specifies the NIS+ domain. The default is the
local domain.
-F Populates NIS+ tables from files.
-f Forces the script to populate the NIS+ tables
without prompting for confirmation.
-h <NIS_server_host> Specifies the NIS server hostname from where
the NIS maps are copied from. This is only used
with the -Y option. This hostname must be
present in the NIS+ hosts or ipnodes table, or
in the /etc/hosts file. If the hostname is not
defined, the script will prompt you for its IP
address, or you can use the -a option to spec‐
ify the address manually.
-l <network_passwd> Specifies the network password for populating
the NIS+ credential table. This is only used
when you are populating the hosts, ipnodes, and
passwd tables. The default passwd is "nisplus".
-n Does not overwrite local NIS maps in
/var/yp/<NISdomain> directory if they already
exist. The default is to overwrite the existing
NIS maps in the local /var/yp/<NISdomain>
directory. This is only used with the -Y
option.
-p <directory_path> Specifies the directory where the files are
stored. This is only used with the -F option.
The default is the current working directory.
-S 0|2 Specifies the authentication level for the NIS+
clients. Level 0 is for unauthenticated clients
and no credentials will be created for users
and hosts in the specified domain. Level 2 is
for authenticated (DES) clients and DES creden‐
tials will be created for users and hosts in
the specified domain. The default is to set up
with level 2 authentication (DES). There is no
need to run nispopulate with -C for level 0
authentication. Also, if other authentication
mechanisms are configured with nisauthconf(1M),
credentials for those mechanisms will also be
populated for the NIS+ clients.
-u Updates the NIS+ tables (ie., adds, deletes,
modifies) from either files or NIS maps. This
option should be used to bring an NIS+ table up
to date when there are only a small number of
changes. The default is to add to the NIS+
tables without deleting any existing entries.
Also, see the -n option for updating NIS+
tables from existing maps in the /var/yp direc‐
tory.
-v Runs the script in verbose mode.
-x Turns the "echo" mode on. The script just
prints the commands that it would have exe‐
cuted. Note that the commands are not actually
executed. The default is off.
-Y Populate the NIS+ tables from NIS maps.
-y <NIS_domain> Specifies the NIS domain to copy the NIS maps
from. This is only used with the -Y option. The
default domainname is the same as the local
domainname.
EXAMPLES
Example 1 Using nispopulate
To populate all the NIS+ standard tables in the domain xyz.sun.com.
from NIS maps of the yp.sun.COM domain as input source where host
yp_host is a YP server of yp.sun.COM:
nis_server# /usr/lib/nis/nispopulate -Y -y yp.sun.COM \
-h yp_host -d xyz.sun.com.
To update all of the NIS+ standard tables from the same NIS domain and
hosts shown above:
nis_server# /usr/lib/nis/nispopulate -Y -u -y yp.sun.COM -h yp_host \
-d xyz.sun.com.
To populate the hosts table in domain xyz.sun.com. from the hosts file
in the /var/nis/files directory and using somepasswd as the network
password for key encryption:
nis_server# /usr/lib/nis/nispopulate -F -p \
/var/nis/files -l somepasswd hosts
To populate the passwd table in domain xyz.sun.com. from the passwd
file in the /var/nis/files directory without automatically creating the
NIS+ credentials:
nis_server# /usr/lib/nis/nispopulate -F -p /var/nis/files \
-d xys.sun.com. -S 0 passwd
To populate the credential table in domain xyz.sun.com. for all users
defined in the passwd table.
nis_server# /usr/lib/nis/nispopulate -C -d xys.sun.com. passwd
To create and populate a non-standard key-value type NIS+ table, pri‐
vate, from the file /var/nis/files/private: (nispopulate assumes that
the private.org_dirkey-value type table has already been created).
nis_server# /usr/bin/nistbladm -D access=og=rmcd,nw=r \
-c private key=S,nogw= value=,nogw= private.org.dir
nis_server# /usr/lib/nis/nispopulate -F -p /var/nis/files private
ENVIRONMENT VARIABLESnispopulate normally creates temporary files in the directory /tmp. You
may specify another directory by setting the environment variable
TMPDIR to your chosen directory. If TMPDIR is not a valid directory,
then nispopulate will use /tmp).
FILES
/etc/inet/hosts local database associating names of nodes with IP
addresses

NIS+ might not be supported in future releases of the Solaris operating
system. Tools to aid the migration from NIS+ to LDAP are available in
the current Solaris release. For more information, visit
