NAME
ypset - point ypbind at a particular server
SYNOPSIS
ypset [ -V1|-V2 ] [ -h host ] [ -d domain ] server
DESCRIPTION
ypset tells ypbind to get network information service (NIS)
services for the specified domain from the ypserv process
running on server. If server is down or is not running
ypserv, this is not discovered until a 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.
ypset is useful for binding a client node which is not on a
broadcast net or is on a broadcast net which isn't running a
NIS server host. It also is useful for debugging NIS client
applications, for instance where a 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. That is, you can type "ypset host1",
and then "ypwhich", and then receive the reply: "host2",
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 (which is running ypserv) gets the binding.
server indicates the NIS server to bind to and can be
specified as a name or an IP address. If specified as a
name, ypset will attempt to use NIS services to resolve the
name to an IP 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 IP address.
Refer to ypfiles(NF) and ypserv(NADM) for an overview of the
network information service.
OPTIONS
-V1 Bind server for the (old) v.1 NIS protocol.
-V2 Bind server for the (current) v.2 NIS protocol.
If no version parameter 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

-h host Set ypbind's binding on host, instead of locally.
host can be specified as a name or as an IP address.
-d domain
Use domain instead of the default domain.
