FTP是一个C/S类型的软件,连接服务端需要FTP客户端才能完成quotetracker，常见的FTP客户端有以下几种:
浏览器quotetracker：可以通过浏览器中输入 ftp://ip或者ftp://域名的方式3分钟了解计算机发展历史-组团学来访问FTP
自带客户端:命令行下可以使用ftp命令去连接
三方客户端：FileZilla 8uftp 图形软件或者文本界面的lftp等
三种方式中quotetracker，文本界面是比较麻烦的quotetracker，无法鼠标流。所以我重点给大家讲解一下

文本方式如何连接
在文本界面中有哪些操作
重点：如何使用ftp命令在文本界面下连接ftp服务器
难点：区分清楚何时操作的是ftp服务器的内容，何时操作的是本地的内容
