ypset(8)							     ypset(8)


  ypset	- point	ypbind at a particular server


  /usr/sbin/ypset [-V1	| -V2] [-d domain] [-h host] server


  -V1 Bind server for the (old)	v.1 NIS	protocol.

  -V2 Bind server for the (current) v.2	NIS protocol.

      If no version is supplied, ypset,	first attempts to set the domain for
      the (current) v.2	protocol. If this attempt fails, ypset,	then attempts
      to set the domain	for the	(old) v.1 protocol.

  -h host
      Set ypbind's binding on host, instead of locally.	The host can be
      specified	as a name or as	an address.

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


  The ypset command tells ypbind to get	Network	Information Service (NIS) map
  information for the specified	domain from the	ypserv process running on
  server. If server is down, or	isn't running ypserv, this is not discovered
  until	an NIS client process tries to get a binding for the domain.  At this
  point, the binding set by ypset will be tested by ypbind.  If	the binding
  is invalid, ypbind will attempt to rebind for	the same domain.


       The ypbind process will refuse ypset requests unless -ypset or
       -ypsetme	are specified when ypbind is started.

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

  In cases where several hosts on the local net	are supplying NIS services,
  it is	possible for ypbind to rebind to another host even while you attempt
  to find out if the ypset operation succeeded.	 For example, you can type:

       % ypset host1
       % ypwhich

  which	can be confusing.  This	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, gets the binding.

  The server indicates the NIS server to bind to, and can be specified as a
  name or an address.  If specified as a name, ypset will attempt to use NIS
  services to resolve the name to an address.  This will work only if the
  node has a current valid binding for the domain in question. In most cases,
  server should	be specified as	an address.

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