I am a long time user of Ubuntu but recently have begun to gain a growing interest in the programming potential of the OS. I recently installed nmap and am trying to learn about the interface and how it works. But when ever I run the following command:

nmap -O -v scanme.nmap.org

as per '' example the rejection comes up as:

TCP/IP fingerprinting (for OS scan) requires root privileges. QUITTING!

what am I doing wrong?

1 Answer

Run it with sudo in front - sudo nmap -O -v scanme.nmap.org

When you're asked for a password enter the one of your user.
