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
