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  ser-
       vices  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 services, 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 transport 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.  Spec-
                      ify host as a name.
