任何人都可以建议一个好的数据包嗅探器类的c ++？寻找一个容易插入的类，我可以在我的c ++程序中使用，没有什么复杂。

推荐答案

你永远不能拦截网络只是通过在你的项目中插入一个类。数据包捕获功能需要内核模式支持，因此您将至少需要让您的应用程序需要或安装libpcap / WinPcap，Will Dean指出。

You will never be able to intercept network traffic just by inserting a class into your project. Packet capture functionality requires kernel mode support, hence you will at the very least need to have your application require or install libpcap/WinPcap, as Will Dean pointed out.

类似Unix的发行版包括开箱即用的libpcap，在这种情况下，您可以看看这个非常简单的示例： http：// www .tcpdump.org / pcap.htm

Most modern Unix-like distributions include libpcap out of the box, in which case you could take a look at this very simple example: http://www.tcpdump.org/pcap.htm

如果你使用的是Windows，你或多或少是自己的，虽然WinPcap 编程与libpcap编程非常相似（不必惊讶，因为它是一个libpcap端口到Win32。）SDK可以在这里找到：http://www.winpcap.org/devel.htm

If you're using Windows, you're more or less on your own, although WinPcap programming is extremely similar to libpcap programming (unsurprisingly, since it's a libpcap port to Win32.) The SDK can be found here: http://www.winpcap.org/devel.htm

无论如何，重要的操作系统，您将需要root /管理员访问实际执行捕获。只要使用库来重放或分析预捕获的数据，就不需要任何特殊的权限。

At any rate, no matter the operating system, you will need root / Administrator access to actually perform a capture. Just using the library to replay or analyze precaptured data doesn't require any special privilege, of course.
