Download Nmap 4.75

Nmap is a program for exploring and monitoring a network. It’s designed to scan a large network without delays, but it also runs smoothly on a single host. The program uses so-called ‘raw ip packets’ to retrieve active hosts and information about the available services. For more information about the possibilities, we refer you to this page. The developers have released another new version with 4.75 as the version number this time. The announcement on the mailing list looks like this:

Hi everyone. I’m delighted to report the release of Nmap 4.75, which has almost 100 significant improvements since 4.68. Some which I’m most excited about are:

• While Nmap stands for “Network Mapper”, it hasn’t been able to actually draw you a map of the network–until now! see here for details and pretty pictures of Zenmap’s new Scan Topology system.
• I spent much of this summer scanning tens of millions of IPs on the Internet (plus collecting data contributed by some enterprises) to determine the most commonly open ports. Nmap now uses that empirical data to scan more effectively.

And there is much more, from hundreds of new OS detection fingerprints to many new Nmap Scripting Engine scripts and libraries. I had no idea how many people still used Windows 2000 until 4.68 came out broken on that platform and I was flooded with email! That’s fixed now. And its just one of many bug fixes and performance improvements in this release. Remember that we had 7 Google SoC students working full-time this summer, and this release includes some of their best work.

You can obtain Nmap 4.75 from the normal location.

Please give it a try! And if you encounter any problems, report them to nmap-dev as described.

Enjoy the release!
