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 regulary. 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.
