NAME
ypinit — build and install Network Information Service databases
SYNOPSIS
/usr/sbin/ypinit -m
[DOM=
NIS_domain]
/usr/sbin/ypinit -s
NIS_server_name
[DOM=
NIS_domain]
/usr/sbin/ypinit -c
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
ypinit
is a shell script that creates Network Information Service
(NIS)
databases on either a master or slave
NIS
server.
ypinit
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
ypinit
recognizes the following options and command-line arguments:
- -m
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 provided to
ypinit
at run-time, or from
ASCII
files in
/etc.
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
ypinit
uses the
NOPUSH=1
option when invoking
make,
so newly formed maps are not immediately copied to slave servers (see
ypmake(1M)).
- -s
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.
- -c
Configures the local host as a NIS client, so that the NIS client
will attempt to bind to a particular NIS server.
Invocation of
ypinit
with a
-c
option prompts the user to construct a list of NIS servers,
in the order of preference, to which the client will try to bind.
This list of NIS servers is stored in the file
/var/yp/binding/<domain_name>/ypservers.
In order for
ypbind
to use this list of NIS servers,
ypbind
should not be invoked with
-broadcast
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
ypinit
-c
installation mechanism could be ignored.
- DOM=NIS_domain
Causes
ypinit
to construct maps for the specified
NIS_domain.
DOM
defaults to the
NIS
domain shown by the
domainname
command (see
domainname(1).
RETURN VALUE
ypinit
returns exit code 0 if no errors occur;
otherwise, it returns exit code 1.
