vsftpd配置

#

# 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.
# 這個選項不是最全的.能夠閱讀vsftpd.conf.5,獲取比較詳細的設置選項
# 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). #容許匿名登錄FTP?(默認註釋掉是容許),
#因此禁止登錄的話,須要手返改爲anonymous_enable=NO
anonymous_enable=YES
#
# Uncomment this to allow local users to log in. #是否容許本地用戶登錄,註釋掉是不容許.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command. #是否容許用戶寫入,當設置爲NO時,則用戶沒法上傳文件
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裏面本地用戶使用的umask值,默認是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 #取消掉註釋,容許匿名用戶上傳文件,這個生效只有在全局的上傳打開才行,你也能夠明顯的建立個目錄
#讓FTP用戶可寫
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES #是否容許匿名用戶創建目錄.
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory. #進入每一個用戶是否顯示歡迎信息
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 #上傳下載文件時記錄日誌
#
# 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! #不建義使用root用戶上傳文件
#chown_uploads=YES #修改匿名用戶上傳的擁有者
#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. #會話超時時間,客戶端鏈接FTP.但沒操做的時間
#idle_session_timeout=600
#
# You may change the default value for timing out a data connection. #數據傳輸超時最長時間
#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服務的運行賬戶.
#
# 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 #是否容許客戶端使用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 #是否容許上傳和下載2進制文件
#ascii_download_enable=YES
#
# You may fully customise the login banner string: #登錄歡迎信息
#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 #指定一個不能離開家目錄的用戶名單
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list #設置名單文件的路徑
#使用上面的方法必須 chroot_local_user=NO
說明:
1.chroot_local_user=YES,單獨這個設置,則全部用戶,被鎖定本身的家目錄中.沒法切換到上一級其它目錄.
2.chroot_local_user=YES,
chroot_list_enable=YES .這2項在一塊兒,則變爲,這個清單下面的用戶/etc/vsftpd/chroot_list,能改變目錄,不會被chroot
3.chroot_local_user=NO
chroot_list_enable=YES, 這2項在一塊兒,則變爲,這個清單下面的用戶不能改變本身的目錄,會被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 #容許使用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 #開啓IPV4監聽
#
# 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 #開啓IPV6監聽
pam_service_name=vsftpd
userlist_enable=YES #直接禁止userlist_file中的用戶登錄.也不提示用戶輸入密碼
tcp_wrappers=YES

# chroot_local_user設置了YES，那麼全部的用戶默認將被chroot，
# 也就用戶目錄被限制在了本身的home下，沒法向上改變目錄。
 
# chroot_list_enable設置了YES，即讓chroot用戶列表有效。
# ★超重要：若是chroot_local_user設置了YES，那麼chroot_list_file
# 設置的文件裏，是不被chroot的用戶(能夠向上改變目錄)
 
# ★超重要：若是chroot_local_user設置了NO，那麼chroot_list_file
# 設置的文件裏，是被chroot的用戶(沒法向上改變目錄)
