Hi, I am very new at windows driver development and I am stuck with a problem that I beleive is a very simple one for most of you. I am trying to make a local copy of the NBL when I get a FilterSendNetBu
fferLists and then forward packets through that local copy. What do you suggest me to do as a newbie? Could you please post some sample code that could help me?
Heya! Thanks for the sample! I've downloaded and compiled it and enabled test mode. I then install and reboot my computer but get this error in the windows system log: "\SystemRoot\sy
stem32\DRIVERS\ ndislwf.sys has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver." I've tried compiling both Windows 7 Debug/Release and the machine I'm running it on is Windows 7 Enterprise. I've looked around but can't find a solution to the problem. Also, in setupapi.app.lo g I get: >>> [Build Driver List - ROOT\MS_NDISLWF \0000] >>> Section start 2013/02/07 16:15:33.896 cmd: C:\windows\Expl orer.EXE cpy: Policy is set to make all digital signatures equal. ! sig: Verifying file against specific (valid) catalog failed!

W22.1.2202 feels a bit alarming but I can't find anyone that have had the same issue or how to solve it. Any idea on what could be wrong or how I should proceed with troubleshooting it?
Are you compiling for the same architecture as your OS? E.g., 32-bit or 64-bit? Do you see any errors in setupapi.dev.lo
g? Check at the bottom for the most recent installation of the ndislwf.sys driver.
Yea, I'm compiling 64bit for my 64bit OS. Thanks for pointing me to that log, it helped me a little bit but I still have the same problem. When I compile the project, two certifications are generated, I install both of them in my trusted root certs but when I try to install my driver I still get the popup about it not being trusted and in the dev log I see: ! sig: Verifying file against specific (valid) catalog failed! (0x800b0109) ! sig: Error 0x800b0109: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.
Can I use the above NDIS 6.0 filter sample with Windows 7 as such or should I port it to NDIS 6.20 filter driver ( by following the steps given at http://msdn.mic
rosoft.com/en-u s/library/windo ws/hardware/ff5 70897(v=vs.85). aspx) ?
This sample code already supports NDIS 6.0, NDIS 6.20, and NDIS 6.30. The VS project will automatically compile with -DNDIS60, -DNDIS620, or -DNDIS630 depending on whether you are targeting Windows Vista, Windows 7, or Windows 8 in Visual Studio. This will automatically change the version of the driver (see the various #ifdef-NDIS_SUP
PORT_NDIS## directives scattered in filter.c). If you are explicitly targeting Windows 7, then you should make sure that the filter is being compiled for Windows 7 with -DNDIS620, and verify that your filter registers with the OS as an NDIS 6.20 driver. You can optionally rip out the bits of 6.0 code, since that's dead code on Windows 7.
Thank you for your prompt reply. I'm very new to driver development. I want to deploy, debug and understand the NDIS Filter driver sample. I'm working with Windows 7 (NDIS 6.20), WDK 8 integrated with Visual Studio 2012. I read the instruction at http://code.msd
n.microsoft.com /windowshardwar e/NDISLWFSYS-Sa mple-NDIS-60-42 b76875#content to build and install. Following the instructions I built the sample, prepared an installation directory and installed the driver. 1. Could you please tell me the next steps to see the working of the sample driver? 2. I'm trying to install and debug on same computer. The video at http://msdn.mic rosoft.com/en-u s/library/windo ws/hardware/hh8 55052.aspx shows that the debugger should run on host computer and driver should be installed on target computer. How do I see the kernel debugger in VS 2012? 3. Right now, I don't want to modify the sample driver, I just want to learn how filter driver works, should I do anything about 'attaching' and 'detaching' the driver? Thank you in advance.
Since that is a more involved topic that is not specific to this sample, let's use your forum thread here to continue the discussion: http://social.m

How can I get send / receive data from NDIS driver and write them down to a txt file? Can someone show a sample of a code that do it?
The easiest way is to use an existing tool, like Microsoft Network Monitor http://www.micr
osoft.com/en-us /download/detai ls.aspx?display lang=en&id=4865 . If you'd like to recreate that tool yourself, you can start with this sample driver. This filter driver gets all send/receive data already; you only need to add in code to write packets to disk. You will probably want to open a file handle in FilterAttach. Create a queue to write data to disk. Then FilterReceiveNe tBufferLists is called for each packet that is received. Because the packets are received at DISPATCH_LEVEL, you cannot write them to disk immediately. Instead, you should copy the packet data to your queue, and have a background worker thread flush the queue out to disk. Note that even a 1Gbps network card can EASILY receive data faster than a typical hard disk can write. Therefore, you should think about how you want to handle the situation where you are getting data faster than the worker thread can write it to disk.

This sample is not for VS2010. It is for VS "next" and WDK8 beta. Please ask <a href="http://so
