Greetings everyone. I'm a Linux noob, and I was wondering if anyone could give me some advice on self-teaching. Where should I start? I preempted this query by buying this book for which I no longer know if I have need. It's Red Hat Linux 9 Unleashed by Sam's. I'm not sure if I understand what the hell Red Hat means exactly. I thought I did, and then I saw a place where they sell some kind of professional edition of the software for $750 US or something. I thought it was free...
My end goal is to be completely versed in Linux and network security, so I can do anything I want with them.
I've been teaching myself C++ up to now, in the interest of learning some game programming eventually. If anyone has advice there, please feel quite free to go all the way. Thanks.
