NAME

ypwhich — return hostname of NIS server of map master

SYNOPSIS

ypwhich

[-T] [-d domain] [[-h] host]

ypwhich

[-fTt] [-d domain] [-h host] -m [mname]

ypwhich

-x

DESCRIPTION

ypwhich tells which NIS server supplies NIS services to a client, or which is the master for a map. If invoked without arguments, it gives the NIS server for the local machine. If host is specified, that machine is queried to find out which NIS server it is using.

The options are as follows:

-d domain

Specify a domain other than the default domain.

-f

When used in conjunction with -m, force ypwhich to query host directly, without using the local copy of ypbind(8).

-h host

Specify a host other than localhost to query for information.

-m [mname]

Find the master NIS server for the named map. mname can be a map name or nickname. If mname is omitted, ypwhich will produce a list of available maps.

-T

Use TCP protocol instead of UDP.

-t

Inhibit translation of map nicknames to their corresponding map names.

-x

Display the map nickname table, found in /var/yp/nicknames. A built-in default translation table is used if /var/yp/nicknames does not exist (see nicknames(5) for details).

EXIT STATUS

ypwhich exits with a non-zero exit code if -m is used, and there was a problem in determining the map's master.
