Download Nmap 3.999

Nmap is a useful program for exploring and monitoring your network. It is designed to scan a large network without delays, but it will also run smoothly on a single host. The program uses so-called ‘raw IP packets’ to find out the active hosts and the available services with all kinds of extra information. For more information about the possibilities, we refer you to this page. The developer of Insecure.org has released Nmap 3.999 with the following changes:

Version 3.999:

• Added runtime interaction support to Windows, thanks to patches from Andrew Lutomirski (luto(a)myrealbox.com) and Gisle Vanem (giva(a)bgnett.no).
• Changed a couple lines of tcpip.cc (put certain IP header fields in host byte order rather than NBO) to (hopefully) support Mac OS X on Intel. Thanks to Kurt Grutzmacher (grutz(a)jingojango.net) for the patch.
• Upgraded the included LibPCRE from version 6.3 to 6.4. There was a report of version detection crashes on the new Intel-based MACs with 6.3.
• Fixed an issue in which the installer would malfunction in rare issues when installing to a directory with spaces in it. Thanks to Thierry Zoller (Thierry(a)Zoller.lu) for the report.

Version 3.99:

• Integrated all remaining 2005 service submissions. The DB now has surpassed 3,000 signatures for the first time. There are now 3,153 signatures for 381 service protocols. Those protocols span the gamut from abc, acap, afp, and afs to zebedee, zebra, and zenimaging. It even covers obscure protocols such as http, ftp, smtp, and ssh :). Thanks to Version Detection Czar Doug Hoyte for his excellent work on this.
• Created a Windows executable installer using the open source NSIS (Nullsoft Scriptable Install System). It handles Pcap installation, registry performance changes, and adding Nmap to your cmd.exe executable path. The installer source files are in mswin32/nsis/ . Thanks to Google SoC student Bo Jiang (jiangbo(a)brandeis.edu) for creating the initial version.
• Fixed a backward compatibility bug in which Nmap didn’t recognize the –min_rtt_timeout option (it only recognized the newly hyphenated –min-rtt-timeout). Thanks to Joshua D. Abraham (jabra(a)ccs.neu.edu) for the bug report.
• Fixed compilation to work again with gcc-derivatives such as MingW. Thanks to Gisle Vanem (giva(a)bgnett.no) for sending the patches
