New Version of the Ubiquitous Network Discovery and Security Auditing Tool – Nmap 6.0 Released

(LiveHacking.Com) – One of the most ubiquitous tools used by network administrators, system administrators and security specialists alike has received an update. Nmap has been updated to version 6.0 and brings a wealth of new features including full IPv6 support.

Since there are no more IPv4 address available the inevitable move to IPv6 is starting to happen (slowly). Nmap took the lead in this change way back in 2002 when it first offered basic IPv6 support. But now, with the release of version 6.0, Nmap has full IPv6 support. IPv6 tools included are OS detection, advanced host discovery and raw-packet IPv6 port scanning. To invoke the IPv6 functionality just add “-6” as a command line option! Also the Nmap website is now available over IPv6.

Nmap 6.0 also offers better web scanning capabilities. As the web has grown and developed the need to scan more than just a set of TCP or UDP ports has arisen. Web applications are accessed via a URL running on port 80. So scaning for the web server (on port 80) is now no longer sufficient. Nmap now includes many techniques for enumerating these web applications. It can also perform a wide variety of other HTTP tasks including web site spidering and brute force authentication cracking.

Other new features in Nmap 6.0 include:

  • An enhanced scripting engine – The Nmap Scripting Engine (NSE) allows users to automate a wide variety of networking tasks. In version 6 the underlying NSE infrastructure has improved and the number of scripts has grown from 59 in Nmap 5 to 348 in Nmap 6.
  • New Nping Tool – The newest member of the Nmap suite of networking and security tools is Nping, an open source tool for network packet generation, response analysis and response time measurement. Nping can generate network packets for a wide range of protocols, allowing full control over protocol headers.
  • Faster scans – Since Nmap 5, the traceroute system has been rewritten for higher performance and increases the parallel execution abilities of the Nmap Scripting Engine and version detection subsystems.

A full list of new features and more screen shots, can be found in the release notes while more detailed information can be found in the change log and supporting documentation. You can download Namp 6 (including the source code)  for Windows, Mac OS X, Linux and several UNIX platforms here.
