With python 3.4.4, used "pip3 install scapy-python3" on a Windows7 VM and I am seeing this error on "from scapy.all import *":

C:\Users\admin>pip3 list ... pip (8.1.2) scapy-python3 (0.18) ...

After more research, it appears that my Win7 VM does not have powershell support for Get-NetAdapter:

"The term 'Get-NetAdapter' is not recognized as the name of a cmdlet, function, script file, or operable program. Check \nthe spelling of the name, or if a path was included, verify that the path is correct and try again.\nAt line:1 char:15\n+ Get-NetAdapter <<<< | select Name, InterfaceIndex, InterfaceDescription, InterfaceGuid, MacAddress | fl\n + CategoryInfo : ObjectNotFound: (Get-NetAdapter:String) [], CommandNotFoundException\n + FullyQualifiedErrorId : CommandNotFoundException\n \n"

I only need scapy-python3 for packet assembly and dissection. In the install guide it mentioned that Win7 could be operated in "offline packet crafting/dissection". Is there a simple way to put it into that mode instead of going down the PowerShell rat hole?

Hello there, I solved this problem in Win7 with updating my PowerShell: Windows Management Framework 4.0. Link: https://www.microsoft.com/en-us/download/details.aspx?id=40855

Thanks @fjjupc for comment I was using latest PowerShell and was not aware of issues with earlier versions. @jp281, please, confirm this solves the issue for you, too, and we can close it.

After upgrading to PSVersion = 4.0, it is still failing at the same spot:

Note that this is a Windows7 VM instance running in VMWare ESX.

jp281 avatar Oct 27 '16 20:10 jp281

Well, did u reboot your instance? Please try again in the powershell after rebooting, thanks.

Yes, I tried after rebooting the Win7 VM, after uninstalling/reinstalling scapy-python3 with pip3. It still ends up with the same error. I have tried by running python 3.4.4/scapy-python3 in a command shell as Administrator and also within the powershell:

Note that if I "import scapy" and then issue "from scapy.all import *" I see a different error regarding pcapdnet:

@jp281 Has this been fixed ?

I also have this problem. installed pip3 install scapy-python3 on a windows 7 environment. I have winpcap installed, which is the problem is in the screenshot above.

That was fixed on the original version of scapy. Feel free to have a look at it
