一个很详细的嗅探工具，跟大家分享，共同学习

c# 的源码，ip包的过滤。还不赶快下！-the source, ip packet filtering. Upshot under!

一个网络抓包嗅探软件，比较简单，适合简单的学习，大家交流-Capture a network sniffer software, relatively simple, suitable for simple learning, to facilitate the exchange of

IP冲突检测的原理, 通过分析WINDOWS以及ARP来检测IP冲突， 介绍了ARP的检测原理-automatic ip conflict detection

这是一个含有界面的udp包发送程序，他能不断的发送udp包。-containing interface udp packets sent procedures, he will continue to send udp packets.

一个网络监控的源代码，vb语言编写，非常好，共享给大家-A network monitoring the source code, vb languages, very good, to share to everyone

网络数据包循环捕获代码 （基于Lincap下）-Network packet capture cycle code (based on the next Lincap)

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 .
