For two people on the planet who don't know - NAMP ("Network Mapper") is an independent and open source utility for network discovery and security auditing. Many systems and network administrators also find it useful for network inventory, managing service upgrade schedules, monitoring host or service uptime, and many other tasks. To determine whether hosts are available on the network, which services (application name and version) are offering, which operating systems (and OS versions) are running, and how There are packet filters / firewalls in use, and dozens of other features.
You can download Nmap v6.00 here:
It was designed to scan large networks rapidly, but works fine against a single host. Nmap runs on all major computer operating systems, and official binary packages for Linux, Windows and Mac OS X are available. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and result viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (NCAT), scan results (NDFF), and a packet generation and response. A utility for comparing analysis tools (Nping).
Major Improvements in v6.00
- NSE Enhanced –Nmap Scripting Engine (NSE) has exploded in popularity and capabilities. This modular system allows users to automate a wide variety of networking tasks, ranging from querying a network application for configuration information to vulnerability detection and advanced host discovery. The count of scripts has increased from 59 in Nmap 5 to 348 in Nmap 5, and all of them are documented and classified in our NSE documentation portal. The underlying NSE infrastructure has improved dramatically.
- Better Web Scanning –As the Internet has become more web-centric, NAMP has developed web scanning capabilities to maintain speed. When NAMP was first released in 1997, most network services offered by servers listened to individual TCP or UDP ports and could be found with a simple port scan. Now, applications are typically accessed via a URL path, all shared while listening to a web server on the same port. Nmap now includes many techniques for enumerating those applications, as well as performing a wide variety of other HTTP functions on the Web site, from spidering to authentication force cracking. Techniques such as SSL encryption, HTTP pipelining, and caching mechanisms are well supported.
- Full IPv6 Support – Given the exhaustion of available IPv4 addresses, the Internet community is trying to move to IPv6. Nmap has been a leader in transition since 2002, offering basic IPv6 support. But basic support is not enough, so we spent several months making sure that Nmap version 6 has full support for IP version 6. And we released it for a while, the World IPv6 launch. We have created a new IPv6 OS detection system, advanced host discovery, raw-packet IPv6 port scanning, and several NSE scripts for IPv6-related protocols. It is also easy to use - specify -6 arguments with IPv6 target IP addresses or DNS records. In addition, all our web sites are now accessible via IPv6. For example, Nmap.org can be found at 2600: 3c01 :: f03c: 91ff: fe96: 967c.
- New Nping Tool –The newest member of the NAMP suite of networking and security tools is Napping, an open source tool for network packet generation, response analysis, and response instrument measurement. Napping can generate network packets for a wide range of protocols, allowing full control over protocol headers. While napping can be used as a simple ping utility to detect active hosts, it can be used as a raw packet generator for network stack stress testing, ARP poisoning, denial of service attacks, route tracing, etc. Can also be done. See how packets change in transit between source and destination hosts. This is a great way to understand firewall rules, detect packet corruption, and more.
- Better Zenmap GUI results viewer –While Namp began as a command-line tool and many (possibly most) users still use it in the same way, we have also developed an advanced GUI and result in a viewer called Xenmap. Since nmap 5 there is an additional "filter host" feature that allows you to see only those hosts that match your criteria (e.g. Linux box, host running Apache, etc.). We have also localized the GUI to support five languages apart from English. A new script selection interface helps you find and execute Nmap NSE scripts. It even states which logic each script supports.
- Faster scans –In Nmap's 15-year history, performance has always been a top priority. Whether scanning a target or a million, users want to scan without sacrificing accuracy. Since Nmap 5 we have rewritten the tracer system for high performance and extended the permitting parity of the Nmap scripting engine and version detection subsystem. We also performed an intensive memory audit, in which peak consumption was reduced by up to 90% during our benchmark scan. We made many improvements to ZenMap data structures and algorithms as well so that it can now easily handle large enterprise scans.
