NAME
ypset - point ypbind at a particular server

SYNOPSIS
/usr/sbin/ypset [ -d domain ] [ -h host ] server

DESCRIPTION
ypset tells ypbind to get the Network Information Service
(NIS) 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 an NIS client process
tries to get 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 which is not on
a broadcast net, or is on a broadcast net which is not
running an NIS server host. It also is useful for debug-
ging 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 supply-
ing 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
service 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.

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 attempts to use NIS services to resolve the
name to an IP address. This works 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.

OPTIONS
-hhost Set ypbind’s binding on host, instead of locally.
host can be specified as a name or as an IP
address.

-ddomain
Use domain , instead of the default domain.

DIAGNOSTICS
Sorry, I couldn’t send my rpc message to ypbind on host
name
The user is not root, or ypbind was run without one
of the -ypset flags. See ypserv(8) for explana-
tions of the -ypset flags.

NOTES
The Network Information Service (NIS) was formerly known
as Yellow Pages (YP). The functionality of the two
remains the same; only the name has changed. The name
