这是一个比较完善的网络协议包的捕获和解析的源码数据包。网络数据包的捕获采用libpcap。非常不错的，大家共同学习进步...

本设计的功能是填充一个TCP数据包，并发送给目的主机。 程序具体要求如下： 1) 以命令行形式运行：SendTCP、source_ip、source_port、dest_ip、dest_port，其中SendTCP是程序名，source_ip为源端IP地址，source_port为源端口号，dest_ip为目的地址，dest_port为目的端口号； 2) 其他的TCP头部参数请自行设定； 3) 数据字段为“This is my homework of network ,I am happy ！” 4) 成功发送后在屏幕上输出“Send OK” 。 -The design features are filled with a TCP packet, and send the purpose of the host. Program specific requirements are as follows: 1) to form the command line run: SendTCP, source_ip, source_port, dest_ip, dest_port, which are SendTCP program name, source_ip client IP address as the source, source_port as the source port number, dest_ip for the purpose of the address, dest_port for the purpose of port number 2) the head of other TCP parameters at your own settings 3) data fields for the This is my homework of network, I am happy! 4) successfully sent the output on the screen after the Send OK .

早期http://music.jschina.com.cn的音乐不让下载，我就编了这个东西，批量获取网址再拿FlashGet下。现在好像它开放下载了，软件也该进博物馆了啊。但是软件的思想应该还青春永驻。有兴趣的研究一下？-early http://music.jschina.com.cn not download music, I on the allocation of this thing, volume access to the website under FlashGet redistributed. It now appears open downloaded, the software into a museum ah. However, the software should also worth thinking. Interest in the study?
