Hello. Here is my problem, I wanna to send raw packet, but when I execute that program, and sniffing my packets, I can`t capture that packet which is sent by that program, what`s wrong here? THNX. C ya.

OS information would be nice, as if my memory serves me correctly Microsoft cut raw socket usage in SP2, the stuff is still there I guess, but just won't work IIRC.

OS, sniffer, and the command you executed is what we need
