NAME
ypmake - create or rebuild Network Information Service databases
SYNOPSIS
source_directory] NIS_domain] passwd_file] shadow_file] [map [map ...]]
source_directory] NIS_domain] passwd_file] shadow_file] [map ...]
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 builds one or more Network Information Service (NIS) maps (databases) on a master NIS server. If no arguments are
specified, either creates maps if they do not already exist or rebuilds maps that are not current. These maps are constructed from ASCII
files. then executes to notify slave NIS servers of the change and make the slave servers copy the updated maps to their machines (see
yppush(1M)).
If any maps are supplied on the command line, creates or updates those maps only. Permissible names for maps are the filenames in listed
under FILES below. In addition, specific maps can be named, such as or
The command can be used instead of (see make(1)). The no longer calls the script but now actually constructs the maps. All NIS commands
have been modified to use the instead of The and can co-exist, but it is recommended that you consider using the which is the standard
mechanism for building maps on other vendor's machines.
Both the and script use five variables:
The directory containing the ASCII
source files from which maps are constructed. defaults to
Causes to construct maps for the specified NIS_domain. defaults to the NIS domain shown by (see domainname(1)).
When non-null (null by default),
inhibits copying the new or updated databases to the slave NIS servers. Only slave NIS servers in the
specified domain receive notification when is null.
Does the same thing as and sends a "clear current map" request to the local process.
Specifies the full pathname of the ASCII
file that should use when building the NIS passwd maps. defaults to
Specifies the full pathname of the ASCII file that
must use in conjunction with the to build NIS password maps. is ignored if is set to 0 in defaults to
The order of arguments passed to is unimportant, but the maps are built or updated in the left-to-right order provided.
Refer to ypfiles(4) and ypserv(1M) for an overview of Network Information Service.
NOTE: The file contains IPv4 and IPv6 addresses. collects data from the file and builds four maps, namely and The and maps contain IPv4
data and the and maps contain IPv4 and IPv6 data.
DIAGNOSTICS
returns one of the following exit codes upon completion:
0 Normal termination; no problems.
1 One or more unrecognized arguments were passed.
2 The NIS domain name is not set.
3 The subdirectory used to contain maps for a specific NIS domain, does not exist or is not writable.
4 An error was encountered when building at least one of the maps.
5 One or more maps' ASCII files do not exist or are unreadable.
EXAMPLES
Create or rebuild the password databases (both the and maps) from and use to copy the databases to any slave NIS servers in the default NIS
domain:
Create or rebuild the hosts databases from but do not copy the databases to any slave NIS servers:
Create or rebuild the network maps from and copy the maps to any slave NIS servers in NIS domain
