Daniel Miessler wrote a nice overview of new nmap features. I highly recommend this to anyone just getting started or looking for a guide for nmap.

At Fyodor’s talk last week at Blackhat he talked about the research he’s been doing, and the ways that research has helped him to improve Nmap. I was lucky enough to attend, and even got to chat with him briefly and get a signed copy of his new book.

Anyway, after receiving numerous complaints over the years regarding performance, he did some colossal scans of the Internet in order to see how Nmap handled extremely large address ranges. What follows is a collection of the most interesting features he added, and information he learned, while doing his research.

Vladimir Mitrovic announced some new features for Zenmap (the Nmap GUI):

As of today (or yesterday, depending on your time zone), Zenmap has a couple of hot new features:

• The network inventory
• Graphical topology visualization

The network inventory is a new concept that allows you to run many scans from inside one Zenmap window, and view all results as if they were a part of one “big” scan. Each host’s information is updated every time a scan targeting it has finished executing. This is done carefully, keeping host information from previous scans if the new scan doesn’t discover anything new about the host.
