ypset

ypset(8)						      System Manager's Manual							  ypset(8)

NAME

       ypset - bind ypbind to a particular NIS server

SYNOPSYS

       ypset [ -d domain ] [ -h hostname ] server

DESCRIPTION

       In   order  to run ypset, ypbind must be initiated with the -ypset or -ypsetme options.	See ypbind(8).	ypset tells ypbind to get NIS ser-
       vices for the specified domain from the ypserv(8) process running on server.

       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:

       example% ypset host1
       example% ypwhich
       host2
       which  can  be confusing. This is a function of the NIS subsystem's attempt to know always a running NIS server, 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.
       Server indicates the NIS server to bind to,  and must be specified as a name or an IP address. This will work only if the node has  a  cur-
       rent  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.
OPTIONS

       -d domain
	      Specify a domain other than the default domain as returned by domainname(1).
       -h hostname
	      Set the NIS binding on host hostname
	       instead of the local machine.
