ypset(8)ypset(8)NAMEypset - point ypbind at a particular server
SYNOPSIS
/usr/sbin/ypset [-V1] [-d domain] [-h host] server
OPTIONS
Bind server for the v.1 NIS protocol. Set ypbind's binding on host,
instead of locally. The host can be specified as a name or as an
address. Use domain, instead of the default domain.
DESCRIPTION
The ypset command tells ypbind to get Network Information Service (NIS)
map information for the specified domain from the ypserv process run‐
ning 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.
Note
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 ser‐
vices, 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 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, 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 ques‐
tion. In most cases, server should be specified as an address.
