[Winpcap-bugs] Undetectable hardware (I think...)

[Gianluca Varenni]

As I said in my previous mail, the first application accessing WinPcap starts the kernel driver (and this requires admin privileges). And then the driver stays in memory, so the second time you run an application the driver is already started and admin privileges are not required.

Have a nice day

  Yes, I think this is right:
  if I use WInPCAP on Vista and start my program as regular user (independent if my account has Admin rights) I do not see any adapters.
  Only "Run as administrator" gives me the list. Funny: second time I can start the same program without admin and the adapters are there.

  I think you hit UAC (User Account Control).
  You need to open the cmd line with elevated privileges (i.e. right-clicking on the cmd line link and choosing "Run as administrator") otherwise you don't have enough privileges to start the winpcap kernel driver.

  Same for any WinPcap-based software. After the first application starts the driver (by running it with elevated privileges), you don't need elevated privileges until the next reboot. A workaround to this is to set the driver to automatically start at boot time. Please follow the directions in this FAQ

  Hope it helps

    WinPcap version: 4.0.2
    Output of windump -D:  Nothing at all (See attached file "picture.jpg").
    OS: Windows Vista Business x86
    Network Adapters: Two on-board.
    NVIDIA nForce Networking Controller
    NVIDIA nForce Networking Controller #2  (names taken from Device Manager)
    Motherboard is an EVGA Nforce 680I motherboard.
    No special networking software that I can think ok. I have Free AVG Anti-virus installed.

    The problem is that the software I'm tyring to use that uses the WinPcap library isn't working (MSN Webcam Recorder). windump -D nor the MSN Webcam Recorder doesn't see my hardware.
