.Dd August 18, 1994 .Dt YPXFR 8 .Os .Sh NAME .Nm ypxfr .Nd get a YP map from YP server .Sh SYNOPSIS .Nm ypxfr .Op Fl bcf .Op Fl d Ar domain .Op Fl h Ar host .Op Fl s Ar domain .Op Fl C Ar tid prog ipadd port .Ar mapname .Sh DESCRIPTION .Nm ypxfr is the utiliy in YP that transfers maps to the local host.
p 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 .Xr crontab 5 . The scripts .Ar ypxfr_1perhour , ypxfr_2perday and .Ar ypxfr_1perday could be used for that.
p The options are as follows: l -tag -width indent t Fl 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. t Fl c Don't send a "Clear current map" to local ypserv process. Useful if ypserv isn't running localy to avoid timeout message. t Fl f Force map transfer, even if version of master is older than local copy. t Fl d Ar domain Don't use default domain, use the specifiyed domain. t Fl h Ar host Get map from host insteed of the maps master host. t Fl s Ar domain Specify a source domain other than the target domain. t Fl C Ar tid prog ipadd port This option is only used by ypserv. This is to open communication with an yppush on another host. .El .Sh FILES l -tag -width /usr/sbin/ypxfr_1perhour -compact t Pa /usr/sbin/ypxfr_1perhour t Pa /usr/sbin/ypxfr_2perday t Pa /usr/sbin/ypxfr_1perday .El .Sh SEE ALSO .Xr yp 8 , .Xr yppush 8 , .Xr ypserv 8 .Sh AUTHOR Mats O Jansson <moj@stacken.kth.se>
