  NAME

    ypwhich - Returns the Network Information Service (NIS) server or map
    master host

  SYNOPSIS

    ypwhich [-d domain] [-V1|-V2] [hostname]

    ypwhich [-t] [-d domain] -m mname

    ypwhich -x

  FLAGS

    -d         Uses domain instead of the default host's domain.

    -V1        Tells which server is serving version 1 NIS protocol-speaking
               client processes.

    -V2        Tells which server is serving version 2 NIS protocol client
               processes.

               If neither version is specified, ypwhich attempts to locate the
               server that supplies the (current) version 2 services.  If no
               version 2 server is currently bound, ypwhich attempts to locate
               the server supplying the version 1 services.  Since NIS servers
               and NIS clients are both backward compatible, knowing the
               version currently in use is unnecessary.

    -t         Inhibits nickname translation.  Useful if there is a map name
               identical to a nickname.

    -m mname   Finds the master NIS server for a map.  No hostname can be
               specified with -m.  The mname parameter can be a map name, or a
               nickname for a map.

    -x         Displays the map nickname table.  This lists the nicknames
               (mnames) the command knows of and indicates the map name
               associated with each nickname.

  DESCRIPTION

    The ypwhich command tells which Network Information Service (NIS) server
    supplies NIS services to an NIS client, or which server is the master for
    a map.

    If ypwhich is invoked without arguments, it gives the NIS server for the
    local machine.  If hostname is specified, the machine is queried to find
    out which NIS master it is using.

    Refer to ypfiles(4) and ypserv(8) for an overview of NIS.

  EXAMPLES

    1.  To find the NIS server for the local machine, enter:

        ypwhich


    2.  To find the NIS master for the passwd.nam map in the dmn domain,
        enter:

        ypwhich -d dmn -m passwd.nam


    3.  To determine which NIS master is serving the sys5 machine, enter:

        ypwhich sys5


  DIAGNOSTICS

    ypwhich:  can't find host
           The specified hostname is not present in the /etc/hosts file.

    ypwhich:  can't call ypbind on host
           The ypbind daemon on the specified host cannot be reached, either
           because the daemon is not currently executing or because of network
           problems.

  EXIT VALUES

    The ypwhich command exits with a value of 0 if successful.  If
    unsuccessful, it exits with a value of 1.
