ypxfrd(8)						      System Manager's Manual							 ypxfrd(8)

NAME

       ypxfrd - High speed NIS map transfer daemon

SYNOPSIS

       /usr/sbin/ypxfrd

DESCRIPTION

       The  ypxfrd daemon is the transfer agent that handles map transfer requests from yppush on the master server and ypxfr on slave servers and
       clients.  This program performs the actual transfer of the NIS maps to slave servers and clients.  Typically, the maps are  transferred	to
       all  slave servers and clients unless the transfer is restricted to those subnets or hosts by an entry or entries in the /etc/yp/securenets
       file.  See ypserv(8) for information on this file.

       The ypxfrd daemon is activated at system startup time by an entry in the /sbin/init.d/nis file of an NIS master server machine. If the  log
       file  /var/cluster/members/{memb}/yp/ypxfrd.log	exists,  ypxfrd  appends all its output to that file. You can use the log file to retain a
       record of what was attempted, and the results.

       See ypfiles(4) and ypserv(8) for an overview of NIS.

RESTRICTIONS

       The ypxfrd daemon transfers NIS maps stored as ndbm files only. It does not transfer maps stored as btree or hash files.

FILES

       The ypxrfd log file. Each cluster member has its own copy.
