i haven’t used nmap much except to scan my home network for fun so if i missed something really important i’d love to know!

also i need to find space in there somewhere for “if you don’t run nmap as root it can’t send icmp (ping) packets, it’s better to run nmap as root”

also be careful when nmapping in a network you don’t administer! it’s a popular hacking tool so using nmap is often discouraged / banned. i made all of the examples in this comic “nmap scanme.nmap.org” and “nmap your home network” for a reason :)

There are are quite a few interesting comments on the thread:

And it taught me about scanme.nmap.org: [WayBack] Go ahead and ScanMe!

Hello, and welcome to Scanme.Nmap.Org, a service provided by the Nmap Security Scanner Project and Insecure.Org.

We set up this machine to help folks learn about Nmap and also to test and make sure that their Nmap installation (or Internet connection) is working properly. You are authorized to scan this machine with Nmap or other port scanners. Try not to hammer on the server too hard. A few scans in a day is fine, but dont scan 100 times a day or use this site to test your ssh brute-force password cracking tool.

Thanks
Fyodor
