Vsftpd完全攻略(五)vsftpd.conf配置詳解

 根據 /etc/vsftpd/vsftpd.conf預設配置給出設定功能

# 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=YES

允許匿名使用者登入

# Uncomment this to allow local users to log in.

local_enable=YES

允許系統使用者名登入

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

write_enable=YES

允許使用任何可以修改檔案系統的FTP的指令

# 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

本地使用者新增檔案的權限

# 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

允許匿名使用者上傳檔案

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

# new directories.

#anon_mkdir_write_enable=YES

允許匿名使用者建立新目錄

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

# go into a certain directory.

dirmessage_enable=YES

允許為目錄配置顯示資訊,顯示每個目錄下面的message_file檔案的内容

# Activate logging of uploads/downloads.

xferlog_enable=YES

開啟日記功能 

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

connect_from_port_20=YES

使用标準的20端口來連接配接ftp 

# 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

所有匿名上傳的檔案的所屬使用者将會被更改成chown_username 

#chown_username=whoever

 匿名上傳檔案所屬使用者名 

# You may override where the log file goes if you like. The default is shown

# below.

#xferlog_file=/var/log/vsftpd.log

日志檔案位置 

# If you want, you can have your log file in standard ftpd xferlog format

xferlog_std_format=YES

使用标準格式 

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

#idle_session_timeout=600

空閑連接配接逾時 

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

#data_connection_timeout=120

資料傳輸逾時 

# 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

當伺服器運作于最底層時使用的使用者名 

# 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

允許使用\"async ABOR\"指令,一般不用,容易出問題 

# 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

 管控是否可用ASCII 模式上傳。預設值為NO

#ascii_download_enable=YES

管控是否可用ASCII 模式下載下傳。預設值為NO

# You may fully customise the login banner string:

#ftpd_banner=Welcome to blah FTP service. 

 login時顯示歡迎資訊.如果設定了banner_file則此設定無效 

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

# useful for combatting certain DoS attacks.

#deny_email_enable=YES

 如果匿名使用者需要密碼,那麼使用banned_email_file裡面的電子郵件位址的使用者不能登入

# (default follows)

#banned_email_file=/etc/vsftpd/banned_emails

禁止使用匿名使用者登陸時作為密碼的電子郵件位址 

# 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

如果啟動這項功能,則所有列在chroot_list_file中的使用者不能更改根目錄 

#chroot_list_file=/etc/vsftpd/chroot_list

定義不能更改使用者主目錄的檔案 

# 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   

是否能使用ls -R指令以防止浪費大量的伺服器資源 

# 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 

綁定到listen_port指定的端口,既然都綁定了也就是每時都開着的,就是那個什麼

standalone模式 

# 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

pam_service_name=vsftpd  

定義PAM 所使用的名稱,預設為vsftpd

userlist_enable=YES 

若啟用此選項,userlist_deny選項才被啟動 

tcp_wrappers=YES 

 開啟tcp_wrappers支援 

<b></b>

<b><b>過濾掉那些注釋,以便我們日後修改配置,大家可以删除vsftpd.conf</b><b>内容,拷貝以下:</b></b>

 

#ftpd_banner=Welcome to blah FTP service.

#ls_recurse_enable=YES

listen=YES

pam_service_name=vsftpd

userlist_enable=YES

tcp_wrappers=YES

為了讓vsftpd的設定選項更全面, 提供一份超詳細vsftpd.conf供查詢參考,具體見附件.
