实验步骤：

一、安装VSFTPD服务器

实验前提，打开VMware Workstation开启Fedora Linux，操作系统必须安装了VSFTPD服务器。

安装VSFTPD服务器，在图形界面“主菜单”中选择“系统设置”——“添加删除应用程序”，找到“VSFTPD服务器”进行安装。

二、VSFTPD服务器的配置

VSFTPD服务器的配置文件有/etc/vsftpd/vsftpd.conf、/etc/vsftpd/vsftpd.ftpusers和/etc/vsftpd.user_list等，根据试验要求，对配置文件进行参数的配置。

打开文件/etc/vsftpd/vsftpd.conf，配置参数“anonymous_enable=YES”，允许匿名帐号登录FTP服务器。

三、VSFTPD服务器的启动

方法1：命令行方式——在终端窗口输入“/etc/rc.d/init.d/vsftpd start”命令启动。

方法2：图形化方式——在桌面选择“系统”——“管理”——“服务器管理”——“服务”，打开“服务配置”窗口，选择“vsftpd” 项，单击“开始”或“重启”按钮即可实现FTP服务启动或重启的操作。

四、网络IP配置

选择“系统”——“网络”，打开“网络配置”窗口，双击打开“以太网设备”窗口，设置IP地址“192.168.1.20”，单击“确定”，在“网络配置”窗口点击“激活”按钮，连接网络。

为了更好的做实验建议把防火墙和SELinux先关了

Vsftpd.conf的文件修改如下:

# 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 #

# Uncomment this to allow local users to log in. local_enable=YES #

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

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

anon_mkdir_write_enable=YES #

# 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 #

# If you want, you can arrange for uploaded anonymous files to be owned by # a different user. Note! Using \# 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 #

# 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 \# 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 #

# 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 # (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 # (default follows)

#chroot_list_file=/etc/vsftpd/chroot_list #

# You may activate the \# default to avoid remote users being able to cause excessive I/O on large

# sites. However, some broken FTP clients such as \# the presence of the \#ls_recurse_enable=YES #

# When \ # 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=NO tcp_wrappers=YES

五、匿名上传

打开终端，输入“ftp 192.168.1.20”，输入用户名和密码，都是“FTP”， 上传自评文件“201024133110.ods”。

六.建立download,upload,full三个文件夹，并分别授予不同的权限

七.实验完成后的画面如下:
