Open Source but Closed Data - pay at the gate, please...
Torsten reports on insecure.com's...mmmm....say funny interpretation of what open source is. I'm not linking to them ,they don't deserve it.
Basically, you need a license to read data files generated by their nmap utility, or to execute nmap and parse the results.
I'll repeat Torsten's words, there's not much more to say: "I am so pissed off".
