因为南京的客户死活要ftp服务而不是sftp，所以我作手用vsftp作为服务器，尝试在windows ftp软件登录进去，特记录vsftp的用法。

配置文件在/etc/vsftpd.conf

有如下代码：

# 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.

#

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).

anonymous_enable=YES

# 设置运行匿名访问登录

#

# Uncomment this to allow local users to log in.

local_enable=YES

# 设置本地用户可以访问，主要是针对虚拟用户

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

write_enable=YES

# 设置可以进行写操作

# 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

# 设置上传文件后文件的权限掩码

# 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

# 是否允许匿名用户上传

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

# new directories.

anon_mkdir_write_enable=YES

# 是否允许匿名用户创建目录

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

# go into a certain directory.

dirmessage_enable=YES

# 设定开启目录标语功能

# Activate logging of uploads/downloads.

xferlog_enable=YES

# 设定开启日志记录功能

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

connect_from_port_20=YES

# 设定端口20进行数据连接

# 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

# 设置是否允许上传文件更改宿主

#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

# 设置vsftpd的服务日志保存路径，该文件默认不存在，必须手动touch出来

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

# Note that the default log file location is /var/log/xferlog in this case.

xferlog_std_format=YES

# 设置日志使用标准的记录格式

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

#idle_session_timeout=600

# 设定空闲的连接超时时间，这里使用默认

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

#data_connection_timeout=120

# 设定单次最大的连续传输时间，这里使用默认。

# 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

# 设定支撑vsftpd 服务的宿主用户为手动建立的vsftpd用户。

# 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

# 设定支持异步传输功能

# 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

#ascii_download_enable=YES

# 设置支持ASCII的上传以及下载模式

# You may fully customise the login banner string:

#ftpd_banner=Welcome to blah FTP service.

# 设置vsftp的登录标语

# 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 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().

# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that

# the user does not have write access to the top level directory within the

# chroot)

#chroot_local_user=YES

#chroot_list_enable=YES

# 设置是否允许用户登出自己的ftp主目录

# (default follows)

#chroot_list_file=/etc/vsftpd.chroot_list

#

# 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

# 设置是否允许用户登录FTP后使用ls -R 的功能，因为这条命令会对系统造成很大的开销

# 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 with two configuration files.

# Make sure, that one of the listen options is commented !!

#listen_ipv6=YES
