NAME
     yppush - force propagation of a changed NIS map

SYNOPSIS
     /usr/etc/yp/yppush [ -v ] [ -d domain ] mapname

DESCRIPTION
     yppush copies a new version of a Network Information Service
     (NIS) map from the master NIS server to the slave NIS
     servers.  It is normally run only on the master NIS server
     by the Makefile in /etc/yp after the master databases are
     changed.  It first constructs a list of NIS server hosts by
     reading the NIS map ypservers within the domain.  Keys
     within the map ypservers are the ASCII names of the machines
     on which the NIS servers run.

     A ``transfer map'' request is sent to the NIS server at each
     host, along with the information needed by the transfer
     agent (the program which actually moves the map) to call
     back the yppush.  When the attempt has completed (success-
     fully or not), and the transfer agent has sent yppush a
     status message, the results may be printed to stdout.  Mes-
     sages are also printed when a transfer is not possible; for
     instance when the request message is undeliverable, or when
     the timeout period on responses has expired.

     Refer to ypfiles(4) and ypserv(1M) for an overview of the
     Network Information Service.

OPTIONS
     -d   Specify a domain.

     -v   Verbose.  This causes messages to be printed when each
          server is called, and for each response.  If this flag
          is omitted, only error messages are printed.

FILES
     ypserv(1M), ypxfr(1M).

BUGS
     In the current implementation (version 2 NIS protocol), the
     transfer agent is ypxfr(1M), which is started by the ypserv
     program.  If yppush detects that it is speaking to a version
     1 NIS protocol server, it uses the older protocol, sending a
     version 1 YPPROC_GET request and issues a message to that
     effect.  Unfortunately, there is no way of knowing if or
     when the map transfer is performed for version 1 servers.
     yppush prints a message saying that an "old-style" message
     has been sent.  The system administrator should later check
     to see that the transfer has actually taken place.
