&支持自由／开源软件的visualc编程网络通信实例展示

信使小精灵,是一个简易的聊天工具。主要是演示了网络编程的主要步骤。本程序使用封装好的函数库，使得应用层不需要考虑网络消息是如何被接受和发送的，也不需要考虑数据粘包和丢包的刺手问题，你只要调用相应的函数就可以了。函数库为你做好了这些工作。你只需要定义自己的协议头和消息结构体，定义好网络消息的回调函数就可以了。-messenger elf is a simple chat tools. A major demonstration is the main network programming steps. The programs use Packaging good libraries, makes application layer need not consider the network news is how it has been accepted and sent, and do not need sticky packets of data and packet loss of a thorn in hand, as long as you call the corresponding function on it. Functions well as your work. You only need to define its own agreement head and the structure of news, the definition of a good network news callback function on it.

一个利用ICMP实现PING命令的工具-ICMP achieve a PING command to use the tools

网络通信程序,实现TCP和UDP通信,可互发消息-network communication procedures, TCP and UDP communications, updates

一个命令行下的嗅探器支持2k/xp/2003 -Under a command-line support 2k/xp/2003 sniffer

一个简单的聊天室程序 源程序齐全 有主机服务器端和客户端-A simple chat room hosts have complete program source server-side and client

测试网络的带宽代码，输入命令，可以根据命令来进行客户端与服务器间的吞吐量测试！-Test network bandwidth code, enter the command, can be carried out under the command between the client and server throughput test!

本程序只对一个IP地址进行，如果要对一段IP进行测试，简单修改程序即可。可将发送放在单独的进程 里(使用fork（）），send_icmp里做成循环，每次重新初始化struct sockaddr_in。那么对接收到的数据 进行分析的proc_icmp（）将多一道对IP报头ip->src字段的判断。-this procedure only a pair of IP addresses, IP to a test, a simple change procedures. This can be placed on a separate process (the use of fork ()), causing Lane send_icmp cycle, each re-initialization struct sockaddr_in. Then Butt received the data analysis proc_icmp () will more than one pair of IP header ip-gt; Src field judgment.
