YPUPDATED(8C)                                                    YPUPDATED(8C)



NAME
       ypupdated, rpc.ypupdated - server for changing NIS information

SYNOPSIS
       rpc.ypupdated [ -is ]

DESCRIPTION
       ypupdated  is a daemon that updates information in the Network Informa-
       tion Service (NIS), normally started up by inetd(8C).   ypupdated  con-
       sults  the file updaters(5) in the directory /var/yp to determine which
       NIS maps should be updated and how to change them.

       By default, the daemon requires the most secure method  of  authentica-
       tion available to it, either DES (secure) or UNIX (insecure).

OPTIONS
       -i     Accept  RPC calls with the insecure AUTH_UNIX credentials.  This
              allows programmatic updating of the NIS maps in all networks.

       -s     Accept only calls authenticated using the secure  RPC  mechanism
              (AUTH_DES  authentication).  This disables programmatic updating
              of the NIS maps unless the network supports these calls.

FILES
       /var/yp/updaters

SEE ALSO
       updaters(5), inetd(8C), keyserv(8C)

NOTES
       The Network Information Service (NIS) was formerly known as Sun  Yellow
       Pages  (YP).   The  functionality of the two remains the same; only the
       name has changed.  The name Yellow Pages is a registered  trademark  in
       the  United  Kingdom  of British Telecommunications plc, and may not be
