List of NIS and NIS+ Programming References

The list of Network Information Service (NIS and NIS+) references includes:

See List of NIS Commands in AIX Version 4.3 Network Information Services (NIS and NIS+) Guide for information about NIS commands and daemons.

Subroutines

yp_all	Transfers all of the key-value pairs from the NIS server to the client as the entire map.
yp_bind	Calls the ypbind daemon directly for processes that use backup strategies when NIS is not available.
yp_first	Returns the first key-value pair from the named NIS map in the named domain.
yp_get_default_domain	Gets the default domain of the node.
yp_master	Returns the machine name of the NIS master server for a map.
yp_match	Searches for the value associated with a key.
yp_next	Returns each subsequent value it finds in the named NIS map until it reaches the end of the list.
yp_order	Returns the order number for an NIS map that identifies when the map was built.
yp_unbind	Manages socket descriptors for processes that access multiple domains.
yp_update	Makes changes to the NIS map.
yperr_string	Returns a pointer to an error message string.
ypprot_err	Takes an NIS protocol error code as input and returns an error code to be used as input to a yperr_string subroutine.

Files

ethers	Lists Ethernet addresses of hosts on the network.
netgroup	Lists the groups of users on the network.
netmasks	Lists network masks used to implement Internet Protocol standard subnetting.
publickey	Stores public or secret keys from NIS maps.
updaters	Contains a makefile for updating NIS maps.
xtab	Lists directories that are currently exported.

NIS+ Commands

Command	Description
nisaddcred	Creates credentials for NIS+ principals and stores them in the cred table.
nisaddent	Adds information from /etc files or NIS maps into NIS+ tables.
niscat	Displays the contents of NIS+ tables.
nischgrp	Changes the group owner of an NIS+ object.
nischmod	Changes an object's access rights.
nischown	Changes the owner of an NIS+ object.
nischttl	Changes an NIS+ object's time-to-live value.
nisdefaults	Lists an NIS+ object's default values: domain name, group name, workstation name, NIS+ principal name, access rights, directory search path, and time-to-live.
nisgrep	Searches for entries in an NIS+ table.
nisgrpadm	Creates or destroys an NIS+ group, or displays a list of its members. Also adds members to a group, removes them, or tests them for membership in the group.
nisinit	Initializes an NIS+ client or server.
nisln	Creates a symbolic link between two NIS+ objects.
nisls	Lists the contents of an NIS+ directory.

nismkdir	Creates an NIS+ directory and specifies its master and replica servers.
nismkuser	Creates an NIS+ user.
nispasswd	Not supported in AIX. Use the passwd command.
nisrm	Removes NIS+ objects (except directories) from the namespace.
nisrmdir	Removes NIS+ directories and replicas from the namespace.
nisrmuser	Removes an NIS+ user.
nissetup	Creates org_dir and groups_dir directories and a complete set of (unpopulated) NIS+ tables for an NIS+ domain.
nisshowcache	Lists the contents of the NIS+ shared cache maintained by the NIS+ cache manager.
nistbladm	Creates or deletes NIS+ tables, and adds, modifies or deletes entries in an NIS+ table.
nisupdkeys	Updates the public keys stored in an NIS+ object.
passwd	Changes password information stored in the NIS+ passwd table.
