Chapter 4. Advanced Nmap Scans

You should now be completely able to run Nmap scans against a variety of hosts. That's great! Knowing how to run a basic scan will get you through many situations, but there are a few notable exceptions—and different scan types—that are vital to become a power user.

We will now specifically cover different methods for host detection (so that you know what to scan), how to run scans against devices that are trying to hide themselves, scanning UDP, different verbosity options, and so on.

In this chapter, we will cover:

  • Running a ping sweep

  • Running a ping agnostic scan

  • Scanning UDP services

  • Running different TCP flags on scans—such as the Xmas Tree scan

  • Operating system detection

  • Increasing verbosity in Nmap output

  • Showing packet tracing in scans
