How do I get /etc/passwd or how do i hack stuff???
I understand your frustration with this problem, however, your question is, well, kind of broad. It’s sort of like asking this: “Hey guys, I got this book on fighting wars and it says to kill the enemy (among other things) to win a battle. I keep trying to kill the enemy and I am getting shot all the time. Is there any easy way of killing the enemy?” I mean that’s the whole point of war, and if it were that easy we wouldn’t have so many of them, I suppose. But anyway, my point is that learning about security is the reason most of us are doing this, and there are so many different factors involved with obtaining /etc/passwd that doing so can be quite varied from one system to another. Be more specific, read a bit more, and by the way don’t break into systems illegally unless you really know what you are doing (and by then you’ll know not to do it in the first place, probably).
