说明：  这个源码是我自己写的，目的是为了模拟ftp协议实现linux主机之间的文件传输，为了简单起见传输方式为二进制方式，源码编辑之后就可以运行，在头文件中指定了server端的ip地址，端口号，最大的连接数，传输过程中的缓冲大小（100个字节），这些都可以重新设置。运行时现在server端运行服务，然后client端可以通过命令行的方式去获取server端的文件（./client server端的文件路径 本地存储路径和文件名）。新手上路，请站长多多指教。
(The source is my own writing, the purpose is to simulate ftp protocol file transfer between linux hosts, for simplicity binary transmission mode, source code can be run after editing, is specified in the header file server side ip address port number, the maximum number of connections, the transmission process of the buffer size (100 bytes), which can be reset. Now run the server-side run-time service, and then through the command line client-side way to access server-side file (./Client server-side path to the local store the file path and file name). New to the road, please webmaster exhibitions.)
