Hi i am working MAC address of machine. I have created a Application which gives me MAC ADDRESS for that machine.
I have observe that every machine on which i have tested i got Following physical address in every machine
Tunnel adapter isatap.{80A45D7C-0F1D-4270-83DC-B03014CF06A1}:
Media State . . . . . . . . . . . : Media disconnected

i have to work with this
Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0
Can anybody please explain me about this,so that i can decide whether i can skip this physical address

Using Vagrant, I am running a Ubuntu box with PHP-FPM and Xdebug 2 in Hyper-V. The network I am using is Hyper-V's default switch.
From my host, I can connect to the Ubuntu box using SSH and the web server is also accessible using the VM's IP address in my browser address bar. From inside the VM, I can access the internet and I can also ping the host by the IP address of the Hyper-V default switch. So the network seems to be set up correctly.
However, the Xdebug debugger running in the VM won't connect to my IDE (PhpStorm) running on my host.
The xdebug.log shows (172.17.96.1 is the IP address of the Hyper-V default switch)

even though PhpStorm on my host seems to be listening on every IP address:
PS C:\Users\me> netstat -a
Active Connections
Proto Local Address Foreign Address State
...
TCP 0.0.0.0:9000 MyLaptop:0 LISTENING
TCP 0.0.0.0:9003 MyLaptop:0 LISTENING
...
If I use telnet in the VM to connect to my host, it doesn't timeout, but it also doesn't connect successfully:
vagrant#ubuntu-18:~$ telnet 172.17.96.1 9000
Trying 172.17.96.1...
It stays at "Trying" forever.
How can I make the Xdebug debugger connect from the VM to PhpStorm on my host?

I am running a Ubuntu box with PHP-FPM and Xdebug 2
Xdebug 2 is no longer supported, please upgrade to Xdebug 3.
The xdebug.log shows (172.17.96.1 is the IP address of the Hyper-V default switch)
That is not true, it shows the IP address from where the HTTP request initiated from, because you have remote IP address discovery turned on. This does not work in all situations, especially with virtualisation. This HTTP address is not necessarily an IP address that the Linux guest can talk to on the host.
You will likely need to use the public IP address of your host, which is 192.168.2.200 for xdebug.remote_host:

And also disable the auto discovery.
When I configure my Windows Server Core with Sconfig it's working well and get an IP from my DHCP server.
But it's not working with PowerShell. I'm using this command:
Set-NetIPInterface -InterfaceAlias "Ethernet 2" -Dhcp Enabled

I am trying to pull ipconfig /all output and put it into a text file. I have created a small VBScript that runs ipconfig without issues. Then I call it in another VBScript. All of this runs, but the output text file remains empty and the primary VBScript doesn't seem to write anything after the ipconfig.vbs runs.
Here is the sample from the primary .vbs script:
' Pulling network config
Set objFSO = WScript.CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("C:\Users\dsadmin\Desktop\LogNet\network_config.txt", 8)
set objFile = objFSO.OpenTextFile("C:\Users\dsadmin\Desktop\LogNet\network_config.txt")
objShell.Run("cscript //nologo C:\Users\dsadmin\Downloads\ipconfig.vbs >C:\Users\dsadmin\Desktop\LogNet\network_config.txt")
Here is the script it calls (ipconfig.vbs):
Set objShell = CreateObject("WScript.Shell")
objShell.Run("ipconfig /all")
I'm out of ideas when it comes to shuffling things around.
You have two problems with that approach
As #Ansgar-Wiechers points out the > redirection is part of CMD.
Once the redirection is working you have to retrieve the Standard Output from the executed command and redirect it to the cscript.exe output. Unfortunately .Run() doesn't provide access to the Standard Output Stream you have to use .Exec() instead.
Here is an example (assumes all files in same direction, but can be modified);
' Pulling network config
Set objShell = CreateObject("WScript.Shell")
Call objShell.Run("%COMSPEC% /c cscript //nologo ipconfig.vbs > network_config.txt")
in the ipconfig.vbs
Set objShell = CreateObject("WScript.Shell")
Set exec = objShell.Exec("ipconfig /all")
'Redirect output from executed command to the script output.
Call WScript.StdOut.Write(exec.StdOut.ReadAll)
Output in network_config.txt

Redirection (>) is a CMD builtin feature. You need to run the statement in CMD to be able to use it:
objShell.Run "%COMSPEC% /c cscript //NoLogo C:\ipconfig.vbs >C:\network_config.txt"
Of course you need to ensure that the second script writes to STDOUT in the first place, as #Lankymart pointed out.
If all your second script does is running ipconfig /all there's not much point in wrapping that in a separate script, though. Just run it directly:
objShell.Run "%COMSPEC% /c ipconfig /all >C:\network_config.txt"
I am trying to get WinDbg to debug a target machine using a manual Ethernet cable as described at https://msdn.microsoft.com/en-us/library/windows/hardware/hh439346(v=vs.85).aspx
However, WinDbg on the host seems to be stuck Waiting to reconnect... forever. Any ideas what could be wrong?
Both machines are running Windows 10 Enterprise x64. I also disabled firewall on both machines.
I double checked both my host and target NICs and made sure they are both supported.
Target NIC is
Intel(R) 82579LM Gigabit Network Connection
PCI\VEN_8086&DEV_1502&SUBSYS_161C103C&REV_04
Host NIC is
Broadcom NetLink(TM) Gigabit Ethernet
PCI\VEN_14E4&DEV_1692&SUBSYS_033D1025&REV_01
bcdedit /dbgsettings shows

debugtype NET
hostip 192.168.0.104

dhcp Yes
The operation completed successfully.
I also made sure the host is accessible from my target machine using ping.
ipconfig /all yields the following:

You can run KDNET utility to check whether your NIC is supported for Kernel Debug or not. KDNET should be in the following path if you install the WDK in the default path:
C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\kdnet.exe
And also, if your NIC is not supported, you can use an virtual machine as a target PC instead, here is the instruction from Microsoft Docs:
Setting Up Kernel-Mode Debugging of a Virtual Machine Manually using a Virtual COM Port
I have a mac running OS X that I need to connect to my company intranet. They have a specific program to do that and it only runs on Windows. I created a windows virtual machine with vmware and I connected it to the VPN.
No, I can't use an alternative program in OS X to connect - like IPSec(protocol), AT&T, etc - and I don't want to reverse engineer the company's tool.
What I need to do now is route the OS X network connection through the windows VM.
Vmware already created a virtual network interface to connect between Windows and OS X.
OS X:
$ifconfig vmnet8
vmnet8: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 00:50:56:c0:00:08
inet 172.16.27.1 netmask 0xffffff00 broadcast 172.16.27.255
I can ping the Windows 7 VM from OS X:
$ ping 172.16.27.2
| | | |
| | vmware(NAT) | |
|Mac (172.16.27.1) |<----------->|Win(172.16.27.2) |
| | | |
The company's tool created a virtual interface called "Ethernet adapter Local Area Connection 2" that contains the company's intranet IP:

How can I access "10.8.15.150" from OS X? How do I make it "magically" route network traffic through the Windows VM into the VPN?
You could run an HTTP proxy in the Windows VM and configure your OS X network connection to route traffic through the proxy.
