ypset(1M)

NAME

     ypset - point ypbind at a particular server

SYNOPSIS

     /usr/sbin/ypset [-d ypdomain] [-h host] server

DESCRIPTION

     In order to run ypset, ypbind must  be  initiated  with  the
     -ypset  or  -ypsetme  options.  See  ypbind(1M). ypset tells
     ypbind to get NIS services for the specified  ypdomain  from
     the  ypserv process running on server. If server is down, or
     is not running ypserv, this might not be discovered until an
     NIS client process tries to obtain a binding for the domain.
     At this point, the binding set by ypset is tested by ypbind.
     If the binding is invalid, ypbind attempts to rebind for the
     same domain.

     ypset is useful for binding a client node that is not  on  a
     broadcast  net, or is on a broadcast net that is not running
     an NIS server host. It is  also  useful  for  debugging  NIS
     client  applications,  for instance, where an NIS map exists
     only at a single NIS server host.

     Where several hosts on the local net are supplying NIS  ser-
     vices,  ypbind  can  rebind  to another host, even while you
     attempt to find out if the ypset operation  succeeded.   For
     example, if you enter the ypset command below, you might get
     the subsequent response from ypwhich:

     example% ypset host1
     example% ypwhich
     host2

     The  sequence  shown  above  is  a  function  of   the   NIS
     subsystem's  attempt to load-balance among the available NIS
     servers, and occurs when host1 does not  respond  to  ypbind
     because  it  is  not  running ypserv (or is overloaded), and
     host2, running ypserv, obtains the binding.

     server indicates which NIS server to bind to,  and  must  be
     specified as a name or an IP address. This works only if the
     node has a current valid binding for the domain in  question
     and  ypbind  has  been  set  to allow use of ypset.  In most
     cases, server should be specified as an IP address.

     ypset tries to bind over a  connectionless  transport.   The
     NIS  library  call, yp_all(), uses connection-oriented tran-
     sport and derives the NIS server's  address   based  on  the
     connectionless address supplied by ypset.

     Refer to ypfiles(4) for an overview of the NIS name service.

OPTIONS

     - d ypdomain
           Use ypdomain, instead of the default domain.

     -h host
           Set ypbind's binding  on  host,  instead  of  locally.
           Specify host as a name.
