DESCRIPTION [Toc] [Back]
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 HP-UX 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,
networks, passwd, protocols, services, rpc, netmasks, bootparams,
netgroup, aliasesandshadow. 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
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
Note that when populating the hosts and passwd tables, nispopulate
will automatically create the NIS+ credentials for all users and hosts
that are defined in the hosts and passwd tables, respectively. A
network passwd is required to create these credentials. This network
password is used to encrypt the secret key for the new users and
Hewlett-Packard Company - 1 - HP-UX 11i Version 2: August 2003
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 credential creation, specify the -S 0
The third SYNOPSIS (-C) is used to populate NIS+ credential table with
level 2 authentication (DES) from the passwd and hosts tables of the
specified domain. The valid table arguments for this operation are
passwd and hosts. If this argument is not specified then it will use
both passwd and hosts as the input source.
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 [Toc] [Back]
-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 passwd and
hosts tables using DES authentication (security
-d NIS+_domain. specifies the NIS+ domain. The default is the
-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. This is only used with the
-Y option. This host must already exist in either
the NIS+ hosts table or /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 specify 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 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
Hewlett-Packard Company - 2 - HP-UX 11i Version 2: August 2003
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 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
-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 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
EXTERNAL INFLUENCES [Toc] [Back]
nispopulate 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.
EXAMPLES [Toc] [Back]
To populate all the NIS+ standard tables in the domain xyz.hp.com.
from NIS maps of the yp.hp.com domain as input source where host
Hewlett-Packard Company - 3 - HP-UX 11i Version 2: August 2003
yp_host is a YP server of yp.hp.com:
/usr/lib/nis/nispopulate -Y -y yp.hp.com -h yp_host -d xyz.hp.com.
To update all of the NIS+ standard tables from the same NIS domain and
hosts shown above:
/usr/lib/nis/nispopulate -Y -u -y yp.hp.com \
-h yp_host -d xyz.hp.com.
To populate the hosts table in domain xyz.hp.com. from the hosts file
in the /var/nis/files directory using "somepasswd" as the network
password for key encryption:
/usr/lib/nis/nispopulate -F -p /var/nis/files -l somepasswd hosts
To populate the passwd table in domain xyz.hp.com. from the passwd
file in the /var/nis/files directory without automatically creating
the NIS+ credentials:
/usr/lib/nis/nispopulate -F -p /var/nis/files -d xys.hp.com. \
-S 0 passwd
To populate the credential table in domain xyz.hp.com. for all users
defined in the passwd table.
/usr/lib/nis/nispopulate -C -d xys.hp.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_dir key-value type table has already been

HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is
LDAP is the recommended replacement for NIS+. HP fully supports the
industry standard naming services based on LDAP.
