————————————————

一、起源

使用golang语言开发了一个网络安全检测的小工具，其中抓取报文模块使用的是google的gopacket包。

开发完成后编译打包成exe可执行文件，本机可以运行，结果一切正常。安装到另一台window10的时候，结果可以运行但是报错结束了。

经过debug定位发现获取网络接口的协程不能正常工作。

二、查看pcap源码

加载kernel32.dll、wpcap.dll、msvcrt.dll依赖库

三、查看环境

通过阅读pcap的源码，知道需要有至少kernel32.dll、wpcap.dll、msvcrt.dll依赖库才可以工作。

在window10上搜索这几个dll依赖库，发现kernel32.dll、msvcrt.dll是存在的，而且不同的应用程序也有自己的dll，搜索出来比较多。

但是wpcap.dll没有找到。

接下来考虑安装wpcap.dll，由于开发环境中安装了Wireshark抓包软件，而通过安装预置条件软件Npcap把wpcap.dll安装解压。

了解到windows X下有两种选择，一种是比较推荐的Npcap，另一种是Npcap的前身WinPcap，对于window10也有单独的Win10Pcap。

对应的官网下载链接和使用手册如下

Npcap   https://nmap.org/npcap/       https://nmap.org/npcap/guide/

WinPcap https://www.winpcap.org/      https://www.winpcap.org/docs/default.htm

Win10Pcap http://www.win10pcap.org/     http://www.win10pcap.org/howto/

四、安装Npcap

Npcap本身是开源项目，后来由Nmap项目维护，笔者还发现有Npcap的OEM版本，支持更多的特性，比如静默安装等等。

https://nmap.org/npcap/

可以下载最新的安装版本，现在是Npcap 1.50 installer for Windows 7/2008R2, 8/2012, 8.1/2012R2, 10/2016, 2019 (x86 and x64)。几乎支持windowX。

如下是安装Npcap的过程。

安装完成后，我们发现C盘下多了目录C:\Program Files\Npcap，里面有一些批处理脚本和组件的安装包，然后C:\Windows\System32\Npcap目录也是新增的，有dll链接库文件。

五、运行demo程序

现在dll都是存在的，而且安装了NPF（网络数据包过滤器）。代码层面不做任何变动立即执行，发现有结果输出。

demo程序可以正常工作，问题解决。

六、获取网卡的各个源码对比

1、golang自身的net库
