Question about raw socket and TCP.

[George2]

Hi, everyone!

I want to implement a mini-TCP protocol that can simulate
TCP's three-time shake hands method and simulate simple
"send" and "recv" method in socket programming. I want to
use raw socket but I am not sure whether there are some
alternative methods.

I just want to get simple implementions to make a concept
proof purpose of how TCP is working. Just for learning purpose.
:-)

I want to know whether there are some sample codes of this
topic that I can make a reference? Must I use RAW SOCKET?
Are there some alterative methods or alternative methods?



Thanks in advance,
George

No offense, but please don't create duplicate threads. You have
another thread a few posts down regarding this same subject.
I realize that you didn't get a reply, but just reply to that thread;
there is no need to create another.

Do you want to simulate a network or do you want to design a network? You do not need sockets to simulate a network. As for a real network connection, yes, one solution is raw socket.

As for code, I recommend that you learn winsock via books. I highly recommend Network Programming for Microsoft Windows, Second Edition by Anthony Jones and Jim Ohmund.

Thanks, kuphryn buddie!

My purpose is only to make up the TCP package manually
and not simply by "connect" which implements three-time
shake hands and "send", "recv" and "accept" etc. Just for
learning the internal of TCP/IP.

I have got and have read chapter 13 "RAW Socket". :-)
My trouble is I do not find some sample code about how
to receive raw socket (raw socket input). In this book, it
only deals with how to output raw sockets (Ping and Tracert
demo). Can you help me to find the sample codes about how
to receive raw socket under Win32 platform.


regards,
George
