You presume things that are not so. There's a lot more that went on in my head than your simplified model.

Keep in mind that I've made it both a personal and professional interest over the years to understand ways to subvert authentication schemes and bypass firewalls and generally reek havoc.

And also keep in mind that my default setting for any new encounter is "trust".

I did in fact scan the code about half a dozen times, looking carefully at the design of the packets. I still don't completely understand what it starts to do, but there's obviously a lot of work going on, and that means that there's a payoff for the user.

So, this thing smells. My spidey sense is not easily activated, and yet it was.

Also, my initial observation was also supported later in the thread. This person is potentially up to no good, and has not yet shown anything to the contrary. This also contributes to a validation of my initial observations.

I'm not as prejudiced as you think I might be. I'm wondering why you're so prejudiced about me. {sigh}
