[Winpcap-users] Building Winpcap for Vista on XP

Mon Feb 9 10:22:14 GMT 2009

Thanks,

The only thing we have changed are the names to make it unique and made the service autostart to get rid of administrator requirement when using winpcap. We have the possibility to sign the driver with our certificate but does the WinPcap has any internal signing procedure we could utilize for branches made on it or do you recoomend us to sign it ourselfs?

Regards,

Bengt

	Hi,

	Thanks a lot. If I understood it right we can run both 32-bits DLL's on a 64-bit machine. Only the driver has to be built for different architectures. 

	How do you sign the driver today? Is it a time consuming task to do (I guess M$ is involved some way)?

You need to buy an x509 certificate from one of the blessed companies and then basically follow some of the instructions in the Kernel-Mode Code Signing Walkthrough white paper from Microsoft

Have a nice day

	Thanks,

	Bengt Werstén

		Hi,

		I have modified it, new name to avoid collision of cource, to only support sending packages in an attempt to have one build usable on XP, Vista and Vista-x64. I have disabled WAN and almost every other feature define to make it small and handy. I can understand that I need two verions of the sys file for each architecture. It is howerver possible to use the same packet.dll on all systems even if I build everything on XP?

	I hope you modified all the names and tested a standard winpcap installation running in parallel with yours :-)

	Regarding the build system, it really doesn't matter at all (except for the driver for NT4, for which you don't care). WinPcap is build completely on an XP machine (apart from the NT4 driver). If you have disabled support for wan, then the same version of packet.dll should work on all the windows NT flavours excluding NT4 (2000/xp/2003/vista/2008). There is just one important thing that you need to be aware of: the driver for x64 should be digitally signed in order for it to load on Vista/2008. This is a requirement from microsoft.

		To sum up, how many version of the files mynpf.sys, mypacket.dll and mywinpcap.dll do I need and how many different systems to have to use to build them on?

	mynpf.sys for x86 and x64 (excluding NT4)

	mypacket.dll (one for x86 and eventually one for x64)

	mywpcap.dll (one for x86 and eventually one for x64) 

	Only one build system.

	GV

		Thanks,

		Bengt Werstén

		You can build the WinPcap DLLs or kernel driver on the OS of your choice, but there are different versions of the driver for x86, x64 and NT4. There are two versions of wpcap (x86 and x64) and a number of versions of packet.dll (NT4, 2000/XP/2003, Vista/2008, in the x86 and x64 version).

		What are you trying to do?

		Have a nice day

			Hi,

			Can I use a winpcap built in a XP x86 environment on any of Vista x86 or Vista x64 or do you need to build it on every system? Please specify if this is true for either Packet.dll or the driver npf.sys.
