Cracking

I'm a hacker and I've been tinkering with lots of stuff over a few years, don't know much about the Web, except for PHP and client-side stuff like HTML, Javascript, CSS.

I'd like to know what I should start learning before getting into cracking (!= hacking) and breaking into servers, but mostly about computer and networks security. I already know Assembly and I can read hexadecimal assembly for Z80 processors for example, so I guess I can get used to some hexadecimal-related stuff.

I do not know anything about the Linux kernel, but I use GNU/Linux operating systems every day 24/7. Also, I have a server running Debian.

What should I learn and how to know more about network security? Thanks.

Inb4 somebody says HTML isn't a programming language, I didn't say it was.

You talk so much about programming, but you cant talk about hacking because you cant actually do anything. I run a hacked network of computers that I programmed to click on googles ads in my secret website. I even write my own viruses to make people get hacked into my network. I work at home and have a bunch of screens showing me what people on my network are doing on their screens. I can even set it so that i can see the code of their computers. can you guys do any of that? I dont think so. I bet you dont know where all the websites real hackers hang out are either? if you name them, I just might tell them that marshviperX sent you.
