Nmap is een programma voor het verkennen en controleren van een netwerk. Het is ontworpen om zonder vertragingen een groot netwerk te scannen en werkt ook zonder problemen op een enkele host. Het programma maakt gebruik van zogeheten 'raw ip packets' om actieve hosts en informatie over de beschikbare services te achterhalen. Meer informatie over de mogelijkheden is te vinden op deze pagina. De ontwikkelaars hebben ter gelegenheid van Defcon enkele dagen geleden versie 5.35DC1 uitgebracht in de ontwikkeltak. De bijbehorende aankondiging ziet er als volgt uit:
Hi folks. It has been 3.5 months since the last Nmap release (5.30BETA1 on March 29), and anyone following the nmap-dev list knows that we've been very busy during that time. So I'm pleased to release Nmap version 5.35DC1 containing the fruits of that labor. The Defcon name is because that conference is awesome! And also because David Fifield and I have an exciting Nmap talk planned there and at Black Hat in a couple weeks (see http://seclists.org/nmap-dev/2010/q3/108).
This release includes 131 NSE scripts (17 new), 6,622 version detection signatures, 2,608 OS fingerprints, and more. I'm particularly excited about the new db2 and ms-sql scripts, and nfs-ls really makes NFS discovery easy! We also added Eugene Alexeev's clever new dns-cache-snoop script. Nping and Ncat were significantly improved as well.
The Nmap 5.35DC1 source code and packages for Linux, Mac OS X, and Windows are available for download at the usual place.
This is a BETA release, but we hope it works well for you. If not (or if you have any suggestions for improvement), please let us know on nmap-dev as described at http://nmap.org/book/man-bugs.html.
Enjoy the new release, and I hope to see you at Defcon!
