详解vsftpd配置文件

Vsftp 配置文档

Vsftp服务器的配置主要在/etc/vsftpd/vsftpd.conf文件的配置上

以下是vsftp的主要配置文件未进行修改时的文件内容。我将用红色笔记进行我的配置说明：

# 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默认情况允许匿名访问

#

# Uncomment this to allow local users to log in.

local_enable=YES允许本地用户访问

#

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

write_enable=YES允许本地用户具有写权限

#

# 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

#

# 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匿名用户具有上传文件的权限

#

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

# new directories.

#anon_mkdir_write_enable=YES匿名用户具有创建文件夹的权限

#

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

# go into a certain directory.

dirmessage_enable=YES

#

# Activate logging of uploads/downloads.

xferlog_enable=YES

#

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

connect_from_port_20=YES数据传输端口20，在这里我要重点说明下如果你要修改端口号，这里要添加几段，首先修改connect_from_port_20=NO，然后添加listen_port=端口号，port_enable=YES，ftp_data_port=端口号。

上面是对vsftpd的port传输模式的配置，接下来我要讲解下vsftpd pasv传输模式的配置:

pasv_enable=YES 启动pasv模式

pasv_min_port=起始地址

pasv_max_port=终止地址 设置pasv模式的端口区间

pasv模式和port 模式可以同时开启

# 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本地用户上传权限

#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

#

# 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默认建立连接延时时间

#

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

#data_connection_timeout=120数据连接延时时间

#

# 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以二进制模式上传

#ascii_download_enable=YES以二进制模式下载

#

# You may fully customise the login banner string:

#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拒绝邮件

# (default follows)

#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用户只限权于用户目录，其他用户禁止访问

# (default follows)

#chroot_list_file=/etc/vsftpd/chroot_list用户ftp目录表

#

# 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

#

# 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

#

# 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

userlist_enable=YES禁止用户访问表

tcp_wrappers=YES
