Hi everyone,

It would appear that this post on technet is correct:

Windows 10 build 10074 does appear to be working again with WinPcap 4.1.3.

        Hi all,

        as reported on this blog post:
        
http://netscantools.blogspot.fr/2015/03/winpcap-and-wireshark-problems-on.html,
        network interfaces are no more showing up on the latest
        Windows 10 build (I see the same thing on my virtual machine).
        I could not find any clear information yet, but I fear it
        could imply that Microsoft is gonna drop the NDIS 5 backward
        compatibility mode sooner or later (which should be expected
        at some point as NDIS 6 was introduced in Vista). Given the
        number of products / projects that rely on WinPcap (Wireshark
        being one of them), having it not working anymore in the
        latest Microsoft OS would be a drama.
        I know that the project is more or less stalling since a few
        years. An "emergency" fix was done for Windows 8 support, but
        I have no idea whether having it working on Windows 10
        requires a small fix or a full rewrite.
        Could one of the developer kindly have a look and provide some
        info regarding the Windows 10 compatibility / WinPCAP future?


    Hi all,

    as indicated by Jakub Zawadzki, there was a Nmap GSoc 2013 project
    porting Winpcap to NDIS 6, with the source code found here:
    https://svn.nmap.org/nmap-exp/yang/NPcap-LWF
    
<https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/installer/winpcap-nmap-4.1.3-NDIS6-1.2.0.exe>
    After a quick test, I can confirm that:
    - interfaces are now seen and can be selected for capture
    - ethernet frames containing TCP packets are seen with a size of
    2048 bytes (while I have a MTU set to 1500) and the extra data is
    seen as ethernet trailer of 570 bytes + a FCS of 4 bytes
    - DNS queries are truncated (only the first 8 bytes of UDP
    datagram are captured)
    So this is not yet usable but seems to be a good starting point.
    http://seclists.org/nmap-dev/2013/q4/108 suggests that the code
    was shared with WinPcap development team (or at least this was the
    intention). Did this ever happened?

    Best regards,
    Pascal.

Pascal,

I haven't seen a reply from a WinPcap developer on this list for a long time, but I can confirm that Nmap is looking to revive the Npcap project. It's one of our "official ideas" for GSOC 2015, and we have several applicants for the position, including the student who did the original work. If you want to stay engaged with that effort, continue to watch the [email protected] <mailto:[email protected]> mailing list over the summer; I'm sure we would appreciate feedback as the project progresses.

Dan
