Learning about Unix networking

Hi,

I would like to learn about Unix networking (as far as I understand, networking is basically the same on *BSD, GNU/Linux and Mac OS X).
In the end, I would like to attempt to write a program that prevents user-chosen programs from connecting to the net (for Mac OS X, there already is an app like that: Little Snitch). I understand that this goal might be unachievable for a newbie like me, but where would I start off to learn about the networking basics needed to write such a program?
I hope this "question" is not too vaguely asked

Thanks for any input!

Hello MrAllan!

In which language would you like to program, or in which language  do you have experience ?

Hello MrAllan!

I have experience in Java, and C/C++ (of which I prefer C++ because of OOP). If necessary, I am willing to learn Python, too.

You *could* use iptables to stop your computer from accessing some urls/ips/ports/protocols...
