I love your posts from defcon. I never have the slightest idea what the fuck you’re talking about.
Xprobe2 is a tool that can be used to point at a computer on a network and based on its particular way of handling various kinds of special network traffic we can hopefully determine the operating system and version that computer is running. This is useful for trying to map out possible penetration tests to run against the system to see if it is secure or not.
