YPWHICH(1)                  General Commands Manual                 YPWHICH(1)



NAME
       ypwhich - return hostname of NIS server or map master

SYNOPSIS
       ypwhich [ -d domain ] [ -m [ mname ] [ -t ] | [ -V1 | -V2 ] hostname ]
       ypwhich -x

AVAILABILITY
       This  command  is  available  with the Networking software installation
       option.  Refer to for information on how to install optional software.

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

       Refer to ypfiles(5) and ypserv(8) for an overview of the NIS services.

OPTIONS
       -d     Use domain instead of the default domain.

       -V1    Which  server  is  serving v.1 NIS protocol-speaking client pro-
              cesses.

       -V2    Which server is serving v.2 NIS protocol client processes.

              If neither version is specified, ypwhich attempts to locate  the
              server that supplies the (current) v.2 services.  If there is no
              v.2 server currently bound, ypwhich then attempts to locate  the
              server  supplying  the  v.1 services.  Since NIS servers and NIS
              clients are both backward compatible, the user  need  seldom  be
              concerned about which version is currently in use.

       -t     Inhibit nickname translation; useful if there is a mapname iden-
              tical to a nickname.  This is not true of any Sun-supplied map.

       -m     Find the master NIS server for a map.  No hostname can be speci-
              fied  with the -m option.  mname can be a mapname, or a nickname
              for a map.  When mname is omitted, produce a list  of  available
              maps.

       -x     Display  the  map  nickname  table.   This  lists  the nicknames
              (mnames) the command knows of, and indicates the mapname associ-
              ated with each nickname.

NOTES
       NIS  was formerly known as Sun Yellow Pages (YP).  The functionality of
       the two remains the same; only the name has changed.  The  name  Yellow
       Pages  is  a  registered  trademark  in  the  United Kingdom of British
       Telecommunications plc, and may not be used without permission.
