YPWHICH(1)                  General Commands Manual                 YPWHICH(1)

     ypwhich - return hostname of NIS server of map master

     ypwhich [-T] [-d domain] [[-h] host]
     ypwhich [-fTt] [-d domain] [-h host] -m [mname]
     ypwhich -x

     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

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