Pun, I also got "PAGE_FAULT_IN_NONPAGED_AREA" type of BOD, in npf.sys module. I do not belive this is an adpater driver issue since I can in fact sniff packets sent out the wireless link.
The adapter I'm using is Cisco System 350 Series Wireless LAN Adapter. In my case the problem only manifested itself when several association/disassociations happened and the PacketSetNumWrites was set at 5000+. The same test went successful pretty consistently when the PacketSetNumWrites was set at 200, and the inter "burst" gap being about 150ms at the application level. -Areg -----Original Message----- From: rujipun [mailto:[EMAIL PROTECTED] Sent: Monday, July 14, 2003 12:44 AM To: [EMAIL PROTECTED] Subject: RE: [WinPcap-users] WinPcap NPF protocol driver crashes in some cases when sending traffic Areg Alimian, You might have read about my problem in email titled "Problem with NPF driver on Wireless Adapter ?". I'm wondering that You and me might have the same problem. What type of BOD happend when your computer crashed ? In my case, it was "PAGE_FAULT_IN_NONPAGED_AREA". My application uses the winpcap.dll to handle the send/recevie traffic on 802.11a/b link. And it has a functionality to hand off between AP and AP, in other words, it has to disassociate and re-associate the wireless link like your application. Now, I wonder that this problem is probably caused by the following two causes, but I still have no proof. 1. Wireless adapter (specifically the driver of the adapter): My WLAN adapter is "Intel PRO/Wireless 5000". May I ask you which wireless adapter you're using ? 2. winpcap(npf.sys): As I mentioned in my last email, I found the crash happened in a module of npf.sys. To your question, I'm sorry that I don't know other way to analyze the problem apart from using windbg.

The packets are sent 5000 at at time (number of writes set to 5000). The system crash happens when the NIC disassociates and re-associates a few times. I have not yet been able to get a dump file using Dr. Watson to see exactly where it crashed. Other than configuring WinDbg on the target machine to get the crash dump file, is there anything else I could do? Any feedback is much appreciated. -Areg Alimian ====================== This is the WinPcap users list.
