NAME
     yppush - force propagation of a changed YP map

SYNOPSIS
     /usr/sbin/yppush [ -v ] [ -d ypdomain ] mapname

DESCRIPTION
     yppush copies a new version of a YP name  service  map  from
     the  master  YP  server to the slave YP servers.  It is nor-
     mally run only on the master YP server by  the  Makefile  in
     /var/yp  after  the  master databases are changed.  It first
     constructs a list of YP server hosts by reading the  YP  map
     ypservers  within the ypdomain, or if the map is not set up,
     the local file is used.  Keys within the map  ypservers  are
     the ASCII names of the machines on which the YP servers run.
     A transfer map request is sent to  the  YP  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 YP name
     service.  The following optionas are available:

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

     -d ypdomain
          Specify a ypdomain other than the default domain.
