Actually you just gave me a link to a page which showed how send/receive packets in c++. I can do that now, thanks, but it's no good to me unless I can use a custom Insim program to tell LFS what to do. I asked if anyone knew of a webpage which explained Insim, which, as I'm told, has pretty much nada to do with c++, considering its a different coding language.
I only mentioned that I'm alright at c++ and Yabasic to show that I'm not a complete noob to programming, like some people who jump in to this forum and ask for programs to be made. Why not give out to them? I'm only trying to find out somewhere where I can learn the language.
