在PC上查找所有物理有线连接 [英] Find All Physical Wired Connections on A PC

问题描述

Hello Codeproject，
出于某种背景，我尝试在我们公司中设置Wake on lan设置.我们大约有50种硬件配置，大部分基于Lenova.我们的主要操作系统是Windows XP.每台PC上都需要更改一些设置.其中一些设置特定于XP，而某些则特定于驱动程序.

Windows XP设置:(已完成)
-允许休眠

驱动程序的设置为:
-允许省电(已完成)
-EnablePME-设置为已启用"
-局域网唤醒-设置为魔术包"

我正处于最初的研究阶段，需要在每台PC上推出所需的配置.我正在寻找一种确定PC上物理有线连接的方法.我的目标是创建有关已知有线连接的报告.使用SCCM，我能够生成所有连接的报告(205个结果)，但包含所有连接，包括蓝牙，虚拟连接，无线等.

到目前为止，我已经看过win32_networkadapter，win32_networkadapterconfiguration.

我也查看了注册表以尝试找到线索.我发现所有网络驱动器配置都存储在:

Hello Codeproject,
For a bit of background, I am attempting to setup Wake on lan settings in our corporation. We have approximately 50 hardware configurations, mostly Lenova based. Our primary OS is Windows XP. There are a few setting that need to be changed on each PC. Some of these settings are specific to XP, and a few are driver specific.

Windows XP Settings: (already complete)
- Allow Hibernate

Settings for the driver are:
- Allow to Save Power (already Complete)
- EnablePME - set to "enabled"
- Wake on Lan Type - set to "Magic Packet"

I am in the initial research phase of pushing out the required configuration on each PC. I am looking for a way to determine the physical wired connections on a PC. My goal is to create a report of the known wired connections. Using SCCM I have been able to generate a report of all connections (205 results) but that contains All connections include blue tooth, virtual connection, wireless etc..

So far I have looked at win32_networkadapter, win32_networkadapterconfiguration.

I have also looked at the registry to try and find a lead. I have discovered that all network drive configuration is stored at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}

到目前为止，注册表项还没有产生任何有用的信息.

任何帮助将不胜感激.

So far registry entries has not produced anything useful.

Any assistance would be appreciated.

推荐答案

我发现的最好方法是通过注册表项的组合.
获取网络连接...也可以直接在注册表中的以下位置找到此信息:HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Class \ {4D36E972-E325-11CE-BFC1-08002bE10318}

查找带有特征" = 132
的所有条目
这将为您提供无线和有线物理连接的列表.

接下来转到HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Network \ {4D36E972-E325-11CE-BFC1-08002BE10318}
使用您在物理连接上找到的实例".在物理连接的键下，您将找到"MediaSubType"键.
-有线连接的值为1.
-无线将具有值2.
-我还观察到其他一些值...我无法找到该枚举的定义.

The best way I have found is through a combination of registry Entries.
Get the network connections... This information can also be found straight in the registry at the path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}

Look for any entries with the "Characteristics" = 132

This will give you a list of physical connections both wireless and wired.

Next go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}
Use the ''instanceid''s that you found on the physical connections. Under the physical connection''s key, you will find the ''MediaSubType'' key.
- Wired connections have value 1.
- Wireless will have the value 2.
- I have also observed a few other values... i have been unable to find the definition of this enum.

检查以下文章: ^ ]

由于WOL数据包需要MAC地址，因此您必须事先将它们保存在应用程序中(注册以唤醒)等，然后使用上面的代码将其发送.

Check the following article : Wake On Lan sample for C#[^]

Because WOL packets need the MAC address you will have to save them beforehand in your application (register to be woken up etc.) then send it using the code above.
