July 31, 2002 (2:37 AM PDT) -- Insecure.Org is pleased to announce the immediate, free availability of the Nmap Security Scanner version 3.00 from http://nmap.org/ .


Nmap is a utility for network exploration or security auditing. It supports ping scanning (determine which hosts are up), many port scanning techniques (determine what services the hosts are offering), and TCP/IP fingerprinting (remote host operating system identification). Nmap also offers flexible target and port specification, decoy/stealth scanning, sunRPC scanning, and more. Most UNIX and Windows platforms are supported in both GUI and command-line modes. Several popular handheld devices are also supported, including the Sharp Zaurus and the iPAQ.

Nmap has been named "Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has also been praised by Network World, Wired, 2600, Computer World, Information Security, Sun World, SANS, the CIO Institute Bulletin, and Phrack. It is currently the 8th most popular program (out of 24,000+) on the Freshmeat.Net software index .


Version 3.00 is the first "stable" release since 2.53 (May '00), and we recommend that all current users upgrade. Improvements from 39 public beta releases have gone into this version.

Here is a list of the most important advantages of Nmap3 over 2.53. See the ChangeLog for a more comprehensive list:


With this "stable" version out of the way, we plan to dive headfirst into the next development cycle. Many exciting features are in the queue, including IPv6 support, service fingerprinting, improved performance against heavily filtered hosts, and more! Developers (or active testers) interested in participating can join the nmap-dev list by sending a blank email to nmap-dev-subscribe@insecure.org . If you want to be notified of new releases and important announcements, send a blank email to nmap-hackers-subscribe@insecure.org to join that list.
