Nmap 5

A new version of Nmap is out, some of the new features include: Addition of Ncat tool for data transfer, redirection, and debugging. This helps in interacting with web servers, mail servers or malware infected machines.

Addition of Ndiff tool to aid in the comparison of Nmap scans. It takes two Nmap XML output files and prints the differences between them.

Improved scripting engine (it was introduced in 4.5 version). This allows users to create simple scripts to automate a wide variety of networking tasks. Nmap added 32 more scripts, they are available here

Improved Zenmap Gui (also introduced in 4.5 version), which is a GUI version of Nmap. It comes with the capability to map a network then save as an .svg file (scalable vector graphic) for visual labeling, or documentation. These files can be used with the open source vector graphic tools like like Inkscape.


I grabbed the latest GUI version and ran a scan against my Linksys Router, here is the output:

If you want to learn more about Nmap, Fydor's book is the best hands down. Part of that book is available for free here
