vsftpd配置

suliu

我用的是debian 4.0 r3系统，使用apt-get install vsftpd安装ftp服务。
默认配置文件如下，红字部分是我加的，蓝字时必须存在的选项
# 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.
#standalone是独立的电脑意思，
listen=YES选yes是独立服务器，必须有此向
#
# Run standalone with IPv6?
# Like the listen parameter, except vsftpd will listen on an IPv6 socket
# instead of an IPv4 one. This parameter and the listen parameter are mutually
# exclusive.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES匿名用户允许登陆，做虚拟用户要NO
#
# Uncomment this to allow local users to log in.
#local_enable=YES本地用户允许登陆
#
# Uncomment this to enable any form of FTP write command.
#write_enable=YES本地用户允许写操作，no了只能浏览
#
# 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本地用户的权限
#
# 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匿名用户允许上传文件
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES匿名用户允许建立目录和写操作
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES切换目录允许提示信息
#
# Activate logging of uploads/downloads.
xferlog_enable=YES打开日志功能
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES使用20端口传输数据，21是控制端口必须有此向
#
# 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
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/vsftpd.log日志文件位置
#
# If you want, you can have your log file in standard ftpd xferlog format
#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允许使用ascii方式上传文件
#ascii_download_enable=YES允许使用ascii方式下载文件
#
# You may fully customise the login banner string:
#ftpd_banner=Welcome to blah FTP service.进入ftp时的欢迎信息
#
# 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 restrict local users to their home directories.  See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
#chroot_local_user=YES所有本地用户登陆后锁定在自家目录，处于安全考虑
chroot是一个linux运行环境，字面意思应该是change root，改变root？对他了解不多，可能是一个很重要的概念。
#
# 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=YESvsftpd.chroot_list名单中的用户有效
# (default follows)
#chroot_list_file=/etc/vsftpd.chroot_listvsftpd.chroot_list的位置，此名单需自己建立，名单名必须是vsftpd.chroot_list
userlist_enable=yes这项配置文件中没有用来限制用户登陆的，开启这项后，匿名用户无效了。
userlist_deny=yes列表中的用户不允许登陆
userlist_file=文件的存放位置
guset_enable=yes启用虚拟用户,虚拟用户启用后，本地用户好像无效了
guest_username=qiang虚拟用户映射为本地的qiang用户
user_config_dir=虚拟用户配置文件位置
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being ab，le 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
#
#
# Debian customization
#
# Some of vsftpd's settings don't fit the Debian filesystem layout by
# default.  These settings are more Debian-friendly.
#
# This option should be the name of a directory which is empty.  Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
secure_chroot_dir=/var/run/vsftpd
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpdvsftpd的验证方式必须有此向
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/vsftpd.pem
