General Questions:
Q.What is Packet Sniffer SDK?
A.Packet Sniffer SDK (PSSDK) libraries are intended for network packet capture and packet generation tasks.
All of the Packet Sniffer SDK implementations work in Gigabit networks, support multi-processor systems (SMP), do not require any pre-installed packet drivers, and have BPF (BSD Packet Filtering) engine implemented at the PSSDK internal driver level.
Using Packet Sniffer SDK you can focus yourself on the high level logics of the application you are developing, rather than on the network drivers, architecture, organization, and network functions realization inside Windows.

Technical questions:
Q.Does Packet Sniffer SDK support multiprocessor (SMP) systems?
A.Yes, it does. Please take into account, that on the multiprocessor system the traffic capture process is more effective if the number of threads created for the work with the network adapter is not less than the processors number in this system.
Q.Is it possible for applications based on Packet Sniffer SDK to work in the Windows Terminal Client sessions?
A.Yes, Packet Sniffer SDK based applications can work in the Windows Terminal Client sessions without any restrictions.
Q.Is it possible using Packet Sniffer SDK to capture the modem traffic?
A.Yes. Please refer to the WANMonitor property of the HNPSManager component. Using HNPSManager.WanMonitorState property you can check if the device \Device\NdisWanBh is installed on the system, then if this device is opened with the MAC filter equal to mfAll, you can capture modem traffic.
Q.Can I use Packet Sniffer SDK library with Visual Basic?
A.Yes, please use Packet Sniffer SDK ActiveX edition.
Q.Can I use Packet Sniffer SDK to drop the incoming packets? Is it possible to use Packet Sniffer SDK to build a firewall?
A.No. Packet Sniffer SDK is developed to capture, generate, and send the packets only. It cannot be used to drop them. To intercept and drop the packets before the Windows TCP/IP stack, you must create appropriate driver.
Q.Is there any versions of the Packet Sniffer SDK library for other compilers supporting WinAPI?
A.Yes, please write us at the .
Q.There are several applications which are using Packet Sniffer SDK running on my computer. Are there any conflicts between these applications are possible, and how many instances of the Packet Sniffer SDK internal driver are loaded in this case?
A.There are no reasons to be worried about - only one copy of driver will be loaded, independently from Packet Sniffer SDK editions are used in these applications. It serves all Packet Sniffer SDK based applications without any conflicts.
