									# Example config file /etc/vsftpd/vsftpd.conf

									#

									# The default compiled in settings are fairly paranoid. This sample file

									# loosens things up a bit, to make the ftp daemon more usable.

									# Please see vsftpd.conf.5 for all compiled in defaults.

									#

									# READ THIS: This example file is NOT an exhaustive list of vsftpd options.

									# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's

									# capabilities.

									#

									# Allow anonymous FTP? (Beware - allowed by default if you comment this out).

									anonymous_enable=NO

									#

									# Uncomment this to allow local users to log in.

									local_enable=YES

									#

									# Uncomment this to enable any form of FTP write command.

									write_enable=YES

									#

									# Default umask for local users is 077. You may wish to change this to 022,

									# if your users expect that (022 is used by most other ftpd's)

									local_umask=022

									#

									# Uncomment this to allow the anonymous FTP user to upload files. This only

									# has an effect if the above global write enable is activated. Also, you will

									# obviously need to create a directory writable by the FTP user.

									#anon_upload_enable=YES

									#

									# Uncomment this if you want the anonymous FTP user to be able to create

									# new directories.

									#anon_mkdir_write_enable=YES

									#

									# Activate directory messages - messages given to remote users when they

									# go into a certain directory.

									dirmessage_enable=YES

									#

									# The target log file can be vsftpd_log_file or xferlog_file.

									# This depends on setting xferlog_std_format parameter

									xferlog_enable=NO

									#

									# Make sure PORT transfer connections originate from port 20 (ftp-data).

									connect_from_port_20=YES

									#

									# If you want, you can arrange for uploaded anonymous files to be owned by

									# a different user. Note! Using "root" for uploaded files is not

									# recommended!

									#chown_uploads=YES

									#chown_username=whoever

									#

									# The name of log file when xferlog_enable=YES and xferlog_std_format=YES

									# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log

									#xferlog_file=/var/log/xferlog

									#

									# Switches between logging into vsftpd_log_file and xferlog_file files.

									# NO writes to vsftpd_log_file, YES to xferlog_file

									xferlog_std_format=YES

									#

									# You may change the default value for timing out an idle session.

									#idle_session_timeout=600

									#

									# You may change the default value for timing out a data connection.

									#data_connection_timeout=120

									#

									# It is recommended that you define on your system a unique user which the

									# ftp server can use as a totally isolated and unprivileged user.

									#nopriv_user=ftpsecure

									#

									# Enable this and the server will recognise asynchronous ABOR requests. Not

									# recommended for security (the code is non-trivial). Not enabling it,

									# however, may confuse older FTP clients.

									#async_abor_enable=YES

									#

									# By default the server will pretend to allow ASCII mode but in fact ignore

									# the request. Turn on the below options to have the server actually do ASCII

									# mangling on files when in ASCII mode.

									# Beware that on some FTP servers, ASCII support allows a denial of service

									# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd

									# predicted this attack and has always been safe, reporting the size of the

									# raw file.

									# ASCII mangling is a horrible feature of the protocol.

									#ascii_upload_enable=YES

									#ascii_download_enable=YES

									#

									# You may fully customise the login banner string:

									#ftpd_banner=Welcome to blah FTP service.

									#

									# You may specify a file of disallowed anonymous e-mail addresses. Apparently

									# useful for combatting certain DoS attacks.

									#deny_email_enable=YES

									# (default follows)

									#banned_email_file=/etc/vsftpd/banned_emails

									#

									# You may specify an explicit list of local users to chroot() to their home

									# directory. If chroot_local_user is YES, then this list becomes a list of

									# users to NOT chroot().

									chroot_local_user=YES

									#chroot_list_enable=YES

									# (default follows)

									#chroot_list_file=/etc/vsftpd/chroot_list

									#

									# You may activate the "-R" option to the builtin ls. This is disabled by

									# default to avoid remote users being able to cause excessive I/O on large

									# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

									# the presence of the "-R" option, so there is a strong case for enabling it.

									#ls_recurse_enable=YES

									#

									# When "listen" directive is enabled, vsftpd runs in standalone mode and

									# listens on IPv4 sockets. This directive cannot be used in conjunction

									# with the listen_ipv6 directive.

									listen=YES

									#

									# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6

									# sockets, you must run two copies of vsftpd with two configuration files.

									# Make sure, that one of the listen options is commented !!

									#listen_ipv6=YES

									pam_service_name=vsftpd

									userlist_enable=YES

									tcp_wrappers=YES

									pasv_enable=YES

									pasv_min_port=1024

									pasv_max_port=1034
