The nispopulate shell script can be used to populate NIS+
tables in a specified domain from their corresponding files
or NIS maps. nispopulate assumes that the tables have been
created either through nisserver(1M) or nissetup(1M).
The table argument accepts standard names that are used in
the administration of Solaris systems and non-standard key-
value type tables. See nisaddent(1M) for more information
on key-value type tables. If the table 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, net-
works, passwd, protocols, services, rpc, netmasks, boot-
params, netgroup, aliases and shadow. Note that the shadow
table is only used when populating 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. nispopulate 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, nispopulate will automatically create the NIS+
credentials for all users and hosts (ipnodes) that are
defined in the
hosts, ipnodes, and passwd tables, respectively. A net-
work passwd is required to create these credentials. 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 creates both LOCAL and DES credentials for users, and
only DES credentials for hosts. To disable automatic creden-
tial 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 mechanisms.
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.
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 authentication
(security level 2). If other authentication mechanisms
are configured using nisauthconf(1M), the NIS+ creden-
tial table will be populated with credentials for
Specifies the NIS+ domain. The default is the local
-F Populates NIS+ tables from files.
-f Forces the script to populate the NIS+ tables without
prompting for confirmation.
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 or
/etc/inet/ipnodes file. If the hostname is not
defined, the script will prompt you for its IP
address, or you can use the -a option to specify the
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.
Specifies the directory where the files are stored.
This is only used with the -F option. The default is
the current working directory.
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 credentials 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 mechan-
isms are configured with nisauthconf(1M), credentials
for those mechanisms will also be populated for the
-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 directory.
-v Runs the script in verbose mode.
-x Turns the "echo" mode on. The script just prints the
commands that it would have executed. Note that the
commands are not actually executed. The default is
-Y Populate the NIS+ tables from NIS maps.
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.
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
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 \
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 automat-
ically 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, "private", 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
nispopulate normally creates temporary files in the direc-
tory /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

NIS+ might not be supported in future releases of the
SolarisTM Operating Environment. Tools to aid the migration
from NIS+ to LDAP are available in the Solaris 9 operating
environment. For more information, visit
