最后更新: Wed Sep 10 2014 12:39:11 GMT+0800

执行

telnet guoshuang.com 80

返回

Trying 64.136.56.122…
Connected to guoshuang.com.
Escape character is ‘^]’.

然后执行

GET / HTTP/1.1 host: guoshuang.com

两次回车，得到类似 curl 的 html 代码。

注意：大小写和换行、两次回车 都必须。（拷贝执行，否则回车会退出 telnet）

只显示头信息

HEAD /index.html HTTP/1.1 host: guoshuang.com

telnet ftp

telnet xxxx.com 21

更多ftp命令(help)：

  • CWD - 等于 cd
  • PASV – 被动模式，客户端连接服务器
  • RETR – 下载文件
  • QUIT – 退出

这些属于 rawftp command，和 ftp shell 不一样！

list（NLST） 之前必须先 pasv

Tells the server to enter “passive mode”. In passive mode, the server will wait for the client to establish a connection with it rather than attempting to connect to a client-specified port. The server will respond with the address of the port it is listening on, with a message like:
227 Entering Passive Mode (a1,a2,a3,a4,p1,p2)
where a1.a2.a3.a4 is the IP address and p1*256+p2 is the port number.
