Getting hardware information using java/jna to work on all operating systems

Hi I am trying to write a java applet that will get some hard ware info, mac address(which I have done), cpuid motherboard serial number and hard drive serial number. I know I need to use jna to do this. My question is, is there a way in c/c++ to get that informati开发者_JAVA百科on that is not platform dependent? Everything i have seen would work only on windows, and I need it to work on all platforms. I need this information so I can create a unique id of that computer. any help or a point in the right direction would be much appreciated.

Not possible. Heck, within the same PC market, querying e.g. BIOS version differs from one MB manufacturer/OEM to another. And that if the PC still has BIOS - not the newer EFI.

Sun/SPARCs are notable exception: their H/W has a relatively unique ID, provisioned mainly for inventorial purposes. It is not precisely unique (what brings up another point) as that might infer on privacy and Sun had no choice but to make sure it is not globally unique.

IOW unique identification of the hardware is illegal in many parts of the world, thus no reliable (least portable) method exists to achieve what you want.

I'd say binding to the MAC address should be already good enough. And that information is rather easy to access on pretty much all platforms. As long as your license check would be lenient enough for user to have sufficient time to receive new license key (in case of hardware replacement) there should be few problems.

There's a project called OSHI that aims to do that. It's looking for contributors to write the *nix implementatoin.
