能让捕获IP层的网络封包

输出netflow的小工具，可以用于netflow分析的测试-NetFlow output of small tools, can be used for NetFlow analysis test

我测试过了，数据包多时，效果不好，可以挂协议分析-I ve tested, and data packets for some time, the effect of poor, can be linked to protocol analysis

linux下的网络监听工具，功能强大，可以抓包，协议分析，监测网络流量等。-of network monitoring tools, powerful, capturing Packet, protocol analysis, network flow.

这是一本关于网络组建与维护的书，对于这方面的新手及专业人员都有一定的参考价值-This is a network on the Establishment and Maintenance of books, in this regard, the newcomers and professionals have some reference value

网络抓包程序的引擎，还包含几个例子 - drivers Binaries of WinPcap s drivers and DLLs for Win95/98/ME, WinNT4 and Win2K. Useful to test the programs. - examples Sample applications showing various uses of winpcap and packet.dll. - lib rary files needed to create capture applications - include include files needed to create capture applications -procedures capturing Packet networks, it also contains several examples- drivers Binaries of WinPcap s drivers and DLLs for Win95/98/ME, quietly and Win2K.

Tracert程序 Tracert（跟踪路由）是路由跟踪实用程序，用于确定 IP 数据报访问目标所采取的路径。Tracert 命令用 IP 生存时间 (TTL) 字段和 ICMP 错误消息来确定从一个主机到网络上其他主机的路由。 本程序利用RAW Socket实现Tracert程序。Tracert程序在具体实现时，是令其向目的主机发送一个ICMP回显请求消息，并重复递增IP头部TTL字段的值。刚开始的时候TTL等于1，这样当数据报抵达途中的第一个路由器时，TTL值就被减为0，导致发生超时错误，因为该路由器生成一份ICMP差错报文返回给源主机。随后，主机将数据报的TTL值递增1，以便IP报文能到达下一个路由器，并由下一路由器生成ICMP超时差错报文返回给源主机。不断重复这个过程，直到数据报达到最终的目的主机，此时目的主机将返回ICMP回显应答消息。这样，源主机只需对返回的每一份ICMP报文进行解析处理，就可以掌握数据报从源主机到达目的主机途中所经过的路由器信息。 本程序为控制台程序-Tracert using WinSocket

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 .

C语言版的HTTP包头解析，符使用实例。-C language version of the HTTP header parsing, address the use of examples.

一个小小实用的网络流量软件，还不错。请大家使用使用-A small utility software, network traffic
