YPWHICH(1)          UNIX Programmer's Manual           YPWHICH(1)



NAME
     ypwhich - which host is the YP server or map master?

SYNOPSIS
     ypwhich [ -d [ _d_o_m_a_i_n ] [ -V1 | -V2 ] [ _h_o_s_t_n_a_m_e ]
     ypwhich [ -t _m_a_p_n_a_m_e ] [ -d _d_o_m_a_i_n ] -m _m_n_a_m_e
     ypwhich -x

DESCRIPTION
     _y_p_w_h_i_c_h tells which YP server supplies yellow pages services
     to a YP client, or which is the master for a map.  If
     invoked without arguments, it gives the YP server for the
     local machine.  If _h_o_s_t_n_a_m_e is specified, that machine is
     queried to find out which YP master it is using.

     Refer to ypfiles(5) and ypserv(8) for an overview of the
     yellow pages.

OPTIONS
     -d      Use _d_o_m_a_i_n instead of the default domain.

     -V1     Which server is serving v.1 YP protocol-speaking
             client processes?

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

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

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

     -m      Find the master YP server for a map.  No _h_o_s_t_n_a_m_e
             can be specified with -m.  _m_n_a_m_e can be a mapname,
             or a nickname for a map.

     -x      Display the map nickname table.  This lists the
             nicknames (_m_n_a_m_e_s) the command knows of, and indi-
             cates the _m_a_p_n_a_m_e associated with each nickname.
