We are looking for a developer with knowledge of TCP/IP Stack implementations and WinPCap experience. We would like to convert p0f (passive OS fingerprinting) into an active multi-threaded C++ DLL that can be called from a C++ or VB6 (Classic) Application.
The right candidate will have suitable knowledge in packet crafting and common OS fingerprinting techniques, the windows packet capture library, as well as VS6 C++ with or without MFC.
The DLL will need to accept a list of IP Addresses and return (via a callback?) the details of the Operating System the IP address belongs to.
