I truly need help on this. I am trying to write a test program that simulate a network environment that have 5 clients and 1 server. To do so, I need to be able to edit IP header to change it's source address and various other values in the header. To change it, I need to use socket raw and IP_HRINCL socket option.
However, it doesn't work during the send with error 10049, "Address not available" from WSAGetLastError(). I am wondering how would I do so, and can I please look at a simple example on how to change your IP header and send it. By the way, I am using winsock with VC++, and my os is XP. I know there are some issues regarding XP's compatibility with Raw socket. In addition, if winsock is not a viable option, is there anyway for me to write in lower socket?
