This is a good narrative description of the a few of the basic types of tcp scanning techniques using nmap. I like the description of spending a friday night spent geeking out. It makes me miss my old viewsonic 21″ CRT that I got for ninety-nine bucks from a busted dot com venture capital business back in the 90’s.
It’s a boring Friday evening - mortals with brains the size of peanuts fill up the local joint exposing whatever is left of their gray matter to the savageness of fermented glucose whilst my DNA donors enjoy the comforts of the flickering images emitted by the crude cathode ray.
I decide to do something productive and as always, end up seated on my cat torn chair staring hypnotically at yet another cathode ray of a much finer resolution. It’s time to fire up my favourite tool and do some poking around. It is indeed odd how my idea of a perfect Friday night is spent cruising along electronic waves, woven and intertwined so perfectly as to permit transport from any one point to another. Ah the wonders of the world wide web. Enough ranting for now then! Let’s get down and dirty.
