i totally agree sysmin. qod: first of all learn about network protocols and at the same time a language (c for example). i've seen a lot of people pretending to be hackers, or crackers or whatever, that didn't know even the basics about networking. that's not hacking. so, i suggest surfing the internet and reading, a lot, about protocols. exploits will come later on the road (and, when u get there -surelly will- u will be writting your own code).
