YPXFR(8)                  BSD System Manager's Manual                 YPXFR(8)

NAME
     ypxfr -- get a YP map from YP server

SYNOPSIS
     ypxfr [-bcf] [-d domain] [-h host] [-s domain] [-C tid prog ipadd port] mapname

DESCRIPTION
     ypxfr is the utiliy in YP that transfers maps to the local host.

     Since the YP master transfers a map when it has changed, an YP slave should check for missed maps regu-lary. regulary.
     lary. This can be done via an entry in crontab(5).  The scripts ypxfr_1perhour, ypxfr_2perday and
     ypxfr_1perday could be used for that.

     The options are as follows:

     -b      Preserve the entry in the database informing a YP server to use DNS to get information about
             unknown hosts. This option will only have effect on the two maps hosts.byname and hosts.byaddr.

     -c      Don't send a "Clear current map" to local ypserv process. Useful if ypserv isn't running localy
             to avoid timeout message.

     -f      Force map transfer, even if version of master is older than local copy.

     -d domain
             Don't use default domain, use the specifiyed domain.

     -h host
             Get map from host insteed of the maps master host.

     -s domain
             Specify a source domain other than the target domain.

     -C tid prog ipadd port
             This option is only used by ypserv. This is to open communication with an yppush on another
             host.
