ypset(1M)                                               ypset(1M)



     NAME
          ypset - point ypbind at a particular server

     SYNOPSIS
          ypset [-V1] [-h host] [-d domain] server

          ypset [-V2] [-h host] [-d domain] server

     DESCRIPTION
          ypset tells ypbind to get YP services for the specified
          domain from the ypserv process running on server.  If server
          is down, or isn't running ypserv, this is not discovered un-
          til a YP 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 YP server host.  It also is useful for debugging YP client
          applications, for instance, where a YP map only exists at a
          single YP server host.

          In cases where several hosts on the local net are supplying
          YP services, it is possible for ypbind to rebind to another
          host even while you attempt to find out if the ypset opera-
          tion succeeded.  That is, you can type ypset host1 and then
          ypwhich, which replies:  host2, which can be confusing.
          This is a function of the YP subsystem's attempt to load-
          balance among the available YP 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 YP server to bind to, and can be speci-
          fied as a name or an IP address.  If specified as a name,
          ypset will attempt to use YP 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(4) and ypserv(1M) for an overview of the
          yellow pages.

     FLAG OPTIONS
          -V1     Bind server for the (old) Version 1 YP protocol.

          -V2     Bind server for the (current) Version 2 YP protocol.

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

                  the domain for the (old) Version 1 protocol.

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

          -d domain
                  Use domain instead of the default domain.
