ypinit(1M) ypinit(1M)
NAME
ypinit - build and install Network Information Service databases
SYNOPSIS
NIS_domain]
NIS_server_name NIS_domain]
Remarks
The Network Information Service (NIS) was formerly known as Yellow Pages (YP). Although the name has changed, the functionality of the
service remains the same.
DESCRIPTION
is a shell script that creates Network Information Service (NIS) databases on either a master or slave NIS server. asks a few self-
explanatory questions, and reports success or failure to the terminal. For an overview of Network Information Service, see ypfiles(4) and
ypserv(1M).
Options
recognizes the following options and command-line arguments:
Create the local host as the master server to all maps (databases)
provided in the NIS domain (see domainname(1)). All maps are built from scratch, either from information pro-
vided to at run-time, or from ASCII files in All such files should be complete and unabbreviated, unlike how
they may exist on a NIS client machine (see passwd(4) for examples of abbreviated files).
See ypmake(1M) for more information on how NIS databases are built on the master server. Note that uses the
option when invoking so newly formed maps are not immediately copied to slave servers (see ypmake(1M)).
Create NIS databases on a slave server by copying the databases from an existing NIS server that serves the NIS domain.
The NIS_server_name argument should be the host name of either the master server for all the maps or a server on
which the maps are current and stable.
Configures the local host as a NIS client, so that the NIS client
will attempt to bind to a particular NIS server. Invocation of with a option prompts the user to construct a
list of NIS servers, in the order of preference, to which the client will try to bind. Each of these NIS
servers must be listed in the file along with its IP Address. This list of NIS servers is stored in the file
This file is used by when invoked without the option. (See ypbind(1M) in ypserv(1M)).
If it is so desired that it is not necessary for a NIS client to bind to a NIS server in a particular list, the
installation mechanism could be ignored.
Causes to construct maps for the specified NIS_domain. defaults to the NIS domain shown by the command (see domain-
name(1).
RETURN VALUE
returns exit code 0 if no errors occur; otherwise, it returns exit code 1.
