vsftpd配置 （转）

 

#

# 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.
# 这个选项不是最全的.可以阅读vsftpd.conf.5,获取比较详细的设置选项
# 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). #允许匿名登陆FTP?(默认注释掉是允许),
#所以禁止登陆的话,需要手返改成anonymous_enable=NO
anonymous_enable=YES
#
# Uncomment this to allow local users to log in. #是否允许本地用户登陆,注释掉是不允许.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command. #是否允许用户写入,当设置为NO时,则用户无法上传文件
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) #FTP里面本地用户使用的umask值,默认是077
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 #取消掉注释,允许匿名用户上传文件,这个生效只有在全局的上传打开才行,你也可以明显的创建个目录
#让FTP用户可写
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES #是否允许匿名用户建立目录.
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory. #进入每个用户是否显示欢迎信息
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=YES #上传下载文件时记录日志
#
# 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! #不建义使用root用户上传文件
#chown_uploads=YES #修改匿名用户上传的拥有者
#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. #会话超时时间,客户端连接FTP.但没操作的时间
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection. #数据传输超时最长时间
#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 #指定vsftp服务的运行帐户.
#
# 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 #是否允许客户端使用sync命令
#
# 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 #是否允许上传和下载2进制文件
#ascii_download_enable=YES
#
# You may fully customise the login banner string: #登陆欢迎信息
#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
#
#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_list_enable=YES #指定一个不能离开家目录的用户名单
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list #设置名单文件的路径
#使用上面的方法必须 chroot_local_user=NO
说明:
1.chroot_local_user=YES,单独这个设置,则所有用户,被锁定自己的家目录中.无法切换到上一级其它目录.
2.chroot_local_user=YES,
chroot_list_enable=YES .这2项在一起,则变为,这个清单下面的用户/etc/vsftpd/chroot_list,能改变目录,不会被chroot
3.chroot_local_user=NO
chroot_list_enable=YES, 这2项在一起,则变为,这个清单下面的用户不能改变自己的目录,会被chroot
# 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 #允许使用ls -r
#
# 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 #开启IPV4监听
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd whith two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES #开启IPV6监听
pam_service_name=vsftpd
userlist_enable=YES #直接禁止userlist_file中的用户登陆.也不提示用户输入密码
tcp_wrappers=YES

# chroot_local_user设置了YES，那么所有的用户默认将被chroot，
# 也就用户目录被限制在了自己的home下，无法向上改变目录。

# chroot_list_enable设置了YES，即让chroot用户列表有效。
# ★超重要：如果chroot_local_user设置了YES，那么chroot_list_file
# 设置的文件里，是不被chroot的用户(可以向上改变目录)

# ★超重要：如果chroot_local_user设置了NO，那么chroot_list_file
# 设置的文件里，是被chroot的用户(无法向上改变目录)
