how do I do raw socket in winxp sp2? I need TOTAL ACCESS TO CREATE IP PACKET, NOT IDIOT RESCRITED VERSION LIKE RAWSOCKET IN SP2
what is easiest way to generate completly unrestricted ip packet?

Write you own network driver. But, of course, many users don't run as admin so there may be no solution that is satisfactory.

Seriously, you will always face this situation. When your clients are using Vista then things get even more bleak because you need to have your driver signed by MS.

Another suggestion is to run Linux. It would be easier to do your own driver there. Lots of free source code available for such purposes.

Although, I am curious as to why you need such functionality? The only uses I have known up till now are 1) for malware infection and 2) security research into problems with current driver/OS network stacks allowing malware infection.

AFAIK Linux does not need anything special since they never removed raw sockets support.

Note The Microsoft implementation of TCP/IP on Windows is capable of opening a raw UDP or TCP socket based on the above restrictions. But other Winsock providers may not support the use of raw sockets.

HOW DOES TCPIP STACK DO IT!? Is code in ws2_32.dll or tcpip.sys? if dll then can be done in usermode, if raw sender in tcpip.sys then need driver. does driver for unrestricted rawsocket exist? if so, where download? if dll, then how does ws2_32.dll generate rawsocket?
what about network card device and ioctl? can i write to network card from usermode?
