要求:
1.用户加密认证
2.允许同时多用户登录
3.每个用户有自己的家目录,且只能访问自己的家目录
4.对用户进行磁盘配额,每个用户的可用空间不同
5.允许用户在ftp server上随意切换目录
6.允许用户查看当前目录下的文件
7.允许上传和下载文件,并保证文件的一致性md5
8.文件传输过程中显示进度条
9.支持文件的断点续传
使用:
1.启动ftp_server.py
2.创建用户,输入:用户名(默认密码是zhurui)
3.启动FTP服务器
4.启动客户端ftp_client.py
5.输入用户名和密码:alex zhurui | william zhurui
6.与服务器server交互:
