组建小型网络的课题设计，很完整，带设计图

sniff源程序 1)能俘获TCP包 2)能解析TCP包 3)能从TCP/IP包中提取出数据-sniff a source) can capture TCP packet 2) Analysis of TCP packets can be three) from the TCP/IP packet data extracted

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?

网络数据包的捕获与分析，用于维护网络安全的软件-The stuff can be used in the capture and analysis of datagrams on the network.It s useful for the security mainteinance.

一个mini抓包发包程序 我利用pcaplib for windows写的一个抓包发包程序Captx for Win2k/Winnt/Win9x， 仅110K，跑起来占内存2M，附有VC源代码，大家有什么特殊需要可以自己修改代码。 使用方法： （1）把整个CapTx目录拷贝到自己的硬盘上 （2）安装packet capture drivers v2.02(Captxdrivers下的相应目录，在网络中添加协议后，选磁盘安装) (3) 启动CapTx.exe (4) 点抓包按钮开始抓包，用单选按钮可以选择转包后的输出格式是详细的还是简单的， 详细的包格式如下： 00000000： FF FF FF FF FF FF 00 45 00 47 00 48 00 08 45 00 .......e.g.h..e. 简单的包格式仅有中间的部分 （5) 该包存到一个跟应用程序相同的目录中的一个log文件中。 (6)往编辑框中填如下所示的包字符： ff ff ff ff ff ff 00 b0 d0 d0 b0 d8 08 06 00 01 08 00 06 04 00 01 00 b0 d0 d0 b0 d8 c0 a8 00 01 00 00 00 00 00 00 c0 a8 00 c9 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 就可以发送一个ARP包了。 （7）该程序由于由源代码，所以你可以根据你额需要随便修改成自己想要的抓包/发包功能。-a mini capturing Packet letting process I use for windows pcaplib wrote an capturing Packet letting process for Win2k/Winnt/Win9x Captx only 110K, running together for 2M memory, with VC source code, you have any special needs can modify the code themselves. Use : (a) the entire CapTx catalog copy of their hard drive (2) Installation of p

一个vc做的数锯包监视程序，值得学习 vc6 vc7可编译通过的完整代码!-vc do a few packets saw surveillance procedures, it is worth learning vc6 vc7 can compile a complete code!

sniff代码,可以进行切听-sniff code that can be cut to listen

tcp包监视分析源码tcpmon-1.0-src.zip-tcp packet analysis and monitoring source tcpmon-1.0-src.zip

能够抓获到达本机网卡的所有报文，并对其进行了初步的协议分析。-Be able to capture all the cards to reach the native packet, and its agreement to conduct a preliminary analysis.

着是易语言的源码-is easy with the source language

得到一个网络数据包，数据结构（基于Lincap）-Receive a network packet data structure (based on Lincap)
