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 #
