实验2:在实验1的基础上进行修改,实现用户既能下载文件,又能上传文件(在/var/ftp下建立一目录upload,将用户上传的资料全部放在此目录下)。其他要求同实验1。
操作过程如下:
vi /etc/vsftpd/vsftpd.conf(代码如下:)(可参考辅助信息完成,见页底)
anonymous_enable=YES
anon_max_rate=30000
data_connection_timeout=60
idle_session_timeout=600
max_clients=50
max_per_ip=5
local_enable=NO
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
pam_service_name=vsftpd
listen=YES
tcp_wrappers=YES
ftpd_banner=Hello!Welcome to my FTP server.This is my first test!
write_enable=YES
anon_other_write_enable=YES
anon_mkdir_write_enable=YES
anon_upload_enable=YES
mkdir /var/ftp/upload
chown ftp /var/ftp/upload
service vsftpd restart
测试
(1)字符界面下如何访问,请参考《ftp命令使用.doc》
(2)在WindowsXP或Linux的Web浏览器中输入ftp://服务器的IP地址,进行访问。
辅助信息:
附:在修改配置文件时,由于大家刚刚接触,若直接清空文件内容后按照上面给出的代码输入,若输入有误便会出现语法错误,而且文件中的注释会对大家起到提示作用,故大家可采用下面的方法:在原有配置文件的基础上进行参数的修改,把不用的注释掉(不要删除),把该添加的添加上去。
下面是针对本实验配置好的文件,红色部分为在原始配置文件基础上做的修改。
# 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 vsftpds
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES(保持不变)
#
# Uncomment this to allow local users to log in.
local_enable=NO(修改)
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES(注释去掉)
#
# 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 ftpds)
#local_umask=022(注释)
#
# 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(注释去掉)
#
# Uncomm
