  47 .Sh DESCRIPTION
  48 .Nm ypxfr
  49 is the utiliy in YP that transfers maps to the local host.
  50 .Pp
  51 Since the YP master transfers a map when it has changed, an YP slave should
  52 check for missed maps regulary. This can be done via an entry in
  53 .Xr crontab 5 .
  54 The scripts
  55 .Ar ypxfr_1perhour , ypxfr_2perday
  56 and
  57 .Ar ypxfr_1perday
  58 could be used for that.
  59 .Pp
  60 The options are as follows:
  61 .Bl -tag -width indent
  62 .It Fl b
  63 Preserve the entry in the database informing a YP server to use
  64 DNS to get information about unknown hosts. This option will only have
  65 effect on the two maps hosts.byname and hosts.byaddr.
  66 .It Fl c
  67 Don't send a "Clear current map" to local ypserv process. Useful if ypserv
  68 isn't running localy to avoid timeout message.
  69 .It Fl f
  70 Force map transfer, even if version of master is older than local copy.
  71 .It Fl d Ar domain
  72 Don't use default domain, use the specifiyed domain.
  73 .It Fl h Ar host
  74 Get map from host insteed of the maps master host.
  75 .It Fl s Ar domain
  76 Specify a source domain other than the target domain.
  77 .It Fl C Ar tid prog ipadd port
  78 This option is only used by ypserv. This is to open communication with
  79 an yppush on another host.
