Trying to write an IRC client but struggling to find a good resource regarding codes and connection protocol?

The RFC documents are certainly not useless! You are correct that you need to send USER followed by NICK . The NOTICE you are getting is that the IRC server is attempting to connect back to your PC via a protocol called IDENTD .

It's a relatively simple protocol but the upshot of it is that it wants to know that a program on the host that is connected to the server, is using the local/remote ports that the server has.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
