ypwhich(1)                                             ypwhich(1)



NAME
     ypwhich - displays the  host  name  of  a  system's  Network
     Information Service (NIS) server

SYNOPSIS
     ypwhich [-d domain-name] [-V1] [host-name]

     ypwhich [-d domain-name] [-V2] [host-name]

     ypwhich [-d domain-name] [[-t] -m [map-or-nickname]]

     ypwhich -x

ARGUMENTS
     -d domain-name
          Specifies a domain other than the local system's domain
          as returned by the domainname command.

     host-name
          Specifies the name of a system to ask about rather than
          the local system.  This argument can be used only with
          the -d, -V1, and -V2 options.

     -m [ map-or-nickname ]
          Displays the NIS master server for a map.  The value of
          map-or-nickname can be a nickname, a long map name, or
          a short map name. See ypcat(1) for a discussion of map
          names and their values. If you do not specify a
          map-or-nickname argument, ypwhich produces a list of
          available maps and their servers.  You cannot specify a
          host-name argument with this option.

     -t map-name
          Inhibits the translation of a nickname to a map name.
          The value of map-name can be a long or short map name.
          See ypcat(1) for a discussion of map names and their
          values.  This option is useful if a map name is
          identical to a nickname.

     -V1  Displays the host name of a server that is serving
          client processing which uses the version 1 NIS
          protocol.  The version 1 protocol is the old version of
          the protocol.

     -V2  Displays the host name of a server that is serving
          client processing which uses the version 2 NIS
          protocol.  The version 2 protocol is the current
          version of the protocol.

     -x   Displays the map nickname table.  The table lists the
          nicknames the command knows of and indicates the long
          map name associated with each nickname.

DESCRIPTION
     ypwhich displays the host name of the NIS server that is
     supplying NIS services to an NIS client or displays the
     system that is the NIS master server for a map.  If run
     without any argument, ypwhich displays the name of the NIS
     server for the local system.  If you specify host-name,
     ypwhich displays the name of that system's NIS master
     server.

     If you do not use the -V1 or -V2 option, ypwhich attempts to
     locate the server that supplies version 2 services.  If no
     version 2 server is currently found, ypwhich attempts to
     locate the server supplying version 1 services.  Because NIS
     servers and clients are backward-compatible, you seldom need
     to be concerned about which version is currently in use.

     Refer to ypfiles(4) and ypserv(1M) for an overview of the
     NIS.
