ypxfr

ypxfr [options] mapname

NFS/NIS command. Transfer an NIS map from the server to the

local host by making use of normal NIS services. ypxfr creates a

temporary map in the directory /var/yp/domain (where domain is

the default domain for the local host), fills it by enumerating the

map’s entries, and fetches the map parameters and loads them. If

run interactively, ypxfr writes its output to the terminal. However,

if it is invoked without a controlling terminal, its output is sent to

syslogd.

Options

-c Do not send a “Clear current map” request to the local ypserv

process.

-C tid prog ipadd port

This option is for use only by ypserv. When ypserv invokes

ypxfr, it specifies that ypxfr should call back a yppush process

at the host with IP address ipadd, registered as program

number prog, listening on port port, and waiting for a

response to transaction tid.

-d domain

Specify a domain other than the default domain.

-f Force the transfer to occur even if the version on the master

server is older than the local version.

-h host

Get the map from host instead of querying NIS for the map’s

master server. host may be specified by name or IP address.

-p dir

Use dir as the path to the NIS map directory instead of /var/yp.

-s domain

Specify a source domain from which to transfer ...
