.SH NAME
\f4ypupdated\fP \- server for changing YP information
.SH SYNOPSIS
\f4/usr/lib/netsvc/yp/ypupdated\fR
[
\f4\-is\fR
]
.SH DESCRIPTION
.P
\f4ypupdated\fR
is a daemon that updates information
in the YP name service, normally started up by
\f4inetd\fR(1M).
\f4ypupdated\fR
consults the file
\f4updaters\fR(4)
in the directory
\f4/var/yp\fR
to determine which YP maps should be updated and how to change them.
.P
By default, the daemon requires the most secure method of
authentication available to it, either
\s-1DES\s0
(secure) or
\s-1UNIX\s0
(insecure).
.P
The following options are available:
.TP
\f4\-i\fR
Accept 
\s-1RPC\s0
calls with the insecure 
\s-1AUTH_UNIX\s0
credentials.
This allows programmatic updating of YP maps in all networks.
.TP
\f4\-s\fR
Only accept calls authenticated using the secure 
\s-1RPC\s0
mechanism
(\s-1AUTH_DES\s0
authentication).
This disables programmatic updating of YP maps unless the network
supports these calls.
