Nmap

From InstallGentoo Wiki
Jump to: navigation, search

nmap is a wicked cool multiplatform port scanning utility, very useful for homemade server projects and to see if your router is properly configured.

It also has a GUI called Zenmap wich is even easier to use and offers some extra options like a fisheye map.

Basics

Remember to use your external IP if you want to see if ports are open to the internet. Scanning your LAN address won't show the same things.

Trivia

  • In the movie Matrix, Trinity uses nmap to find out SSH runs in port 22 of all things.
