# NAME

`ypxfr`, `ypxfr_1perhour`, `ypxfr_1perday`, `ypxfr_2perday` — get a YP map from YP server

# SYNOPSIS

`ypxfr` | [`-cf`] [`-C` tid prog ipadd port] [`-d` domain] [`-h` host] [`-s` domain] mapname

# DESCRIPTION

`ypxfr` is the utility in YP that transfers maps to the local host.

Since the YP master transfers a map when it has changed, a YP slave should check for missed maps regularly. 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:

`-C` tid prog ipadd port
  This option is only used by ypserv. This is to open communication with a yppush on another host.
`-c`
  Don't send a "Clear current map" to local ypserv process. Useful if ypserv isn't running locally to avoid timeout message.
`-d` domain
  Don't use default domain, use the specified domain.
`-f`
  Force map transfer, even if version of master is older than local copy.
`-h` host
  Get map from host instead of the maps master host.
`-s` domain
  Specify a source domain other than the target domain.
