# Example config file /etc/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.

#
# Run standalone?  vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
# 如果是yes表示vsftpd是以standalone的方式来启动的,默认为NO;
listen=YES
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
listen_ipv6=YES

# Allow anonymous FTP? (Disabled by default).

# 是否允许匿名登录

# 将某个特殊的email addres阻止, 防止其登陆
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails

# 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.

# 匿名用户上传数据的权限 默认为NO; 如果设置为YES则anon_other_write_enable必须为YES
#anon_upload_enable=YES

# Uncomment this to allow local users to log in.

# 该值设置为yes 时候;在/etc/passwd内的账号才能以实体用户的方式登录ftp服务器
local_enable=YES

#实体用户传输速率限制; 单位是bytes/seconds

# Uncomment this to enable any form of FTP write command.
# 如果允许用户上传数据, 需要设置为yes

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

# If enabled, vsftpd will display directory listings with the time

# 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.

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

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