In looking at the output provided, it appears you are running nmap as a user and not as root or a privileged user, which is a requirement in order to take full advantage of its capabilities.

I recommend typing "sudo su" and press Enter, then retype your password to become superuser.

Next, run nmap, e.g. "nmap -p 80-82 0.18.0.0" replacing the 0.18.0.0 with a legitimate IP address to see how you fare.

I suspect you'll have better success or at least, you're a step closer.
