FTP ~ Update Problem

#
# To have more informations about Proftpd configuration
# look at : http://www.proftpd.org/
#


# This is a basic ProFTPD configuration file (rename it to 
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.


ServerName			"ProFTPD"
#ServerType			standalone
ServerType			inetd
DefaultServer			on


<Global>
<IfModule mod_tls.c>
	# common settings for all virtual hosts
	TLSEngine on
	TLSRequired off


	TLSLog /var/log/plesk/ftp_tls.log


	TLSRSACertificateFile /opt/psa/admin/conf/httpsd.pem
	TLSRSACertificateKeyFile /opt/psa/admin/conf/httpsd.pem


	# Authenticate clients that want to use FTP over TLS?
	TLSVerifyClient off


	# Allow SSL/TLS renegotiations when the client requests them, but
	# do not force the renegotations.  Some clients do not support
	# SSL/TLS renegotiations; when mod_tls forces a renegotiation, these
	# clients will close the data connection, or there will be a timeout
	# on an idle data connection.
	TLSRenegotiate none


	# As of ProFTPD 1.3.3rc1, mod_tls only accepts SSL/TLS data connections 
	# that reuse the SSL session of the control connection, as a security measure.
	# Unfortunately, there are some clients (e.g. curl) which do not reuse SSL sessions. 
	TLSOptions NoSessionReuseRequired

# To prevent DoS attacks, set the maximum number of child processes
