#8347 — Raw Socket programming

Hi there, 

I want to configure and send a simple packet (TCP or UDP) between two devices in a local network using static IP configuration. 
But, I am not aware of the logical process of about the layers that I need to programming and configure. Meaning, I need a TCP/IP stack socket and this socket will communicate with the drivers of the specific NIC card that I have? 
To be honest I dont know exactly the steps and what I need to configure.

P.S. I want to use a Bare-metal TCP/IP stack like LW:IP that does not need the existance of a OS. 


Can anyone explain me / describe to me the logical process in bullets style what I need to programming. 

Many thanks

A simple packet suggests UDP.  TCP is a stream protocol.

What system and what language?

On Unix-like systems the low-level outline for something like a C
program is:

For the receiver:
  Create a socket.
  Call bind with a zero address to associate a local IP address with it.
  Call listen to indicate that the socket is read to accept data.
  Wait for data using something like select.

For the sender:
  Create a socket.
  Call bind with the destination address.
  Use send to send (or write) to send a datagram.

(Note: It's been a while, so you will have to check this.)

I think you're right.
