The same case with receiving packets (via ReceiveNetBufferListsHandler and ReturnNetBufferListsHandler functions).ĭo I understand correctly that there is an opportunity to drop a packet by NPF, send/recv it to/from network, and remove it from 'capturing packet list'? If we want to cut this packet from capturing, we need to assembly new NBL (without unwanted packets) and call NdisFIndicateReceiveNetBufferLists with new NBList.If we want to drop a packet, we need to assembly new NBL (without unwanted packets) and call SendNetBufferListsCompleteHandler with new NBList.Parsing NBL: parse each buffer and check packet characteristics.(to be exact - NetBufferList via SendNetBufferListsHandler and SendNetBufferListsCompleteHandler functions) dumpcap starts listening packets on eth0.My main question: if NPF drops a packet (packets) it means that packets will not be captured or that packets will not be sent/received? I provide the main figures from WinPcap page bellow because they are related to the question. Operating System: Windows 10 Enterprise Version 1709 (OS Build 16299.I read about how WinPcap filters packets here and examined ndis/filter project from GitHub ( Microsoft/Windows-driver-samples).

I have tried this with stable version of Docker and also same issue with previous version of Windows as I had this problem for over a year. I am wondering what tools or how Microsoft engineers do packet capturing inside a container? but tshark would not report any usable interface. I also tried npcap, installed sucessfully. I also installed Winpcap sucessfully, but npf driver can not be started. Or netsh trace start globallevel=5 provider=microsoft-windows-winnat level=5 provider=Microsoft-Windows-TCPIP level=5 report=di capture=yesĪnd I will get this error message: The inbox capture driver could not be started (error=0x800106d9). I am wondering how can I do packet logging inside docker? I am trying this (inside container): netsh trace start persistent=yes capture=yes tracefile=c: emp ettrace-boot.etl.
