Whats new in version 6.40-2:
- [Ncat] Fixed compilation when --without-liblua is specified in configure (an #include needed an ifdef guard). [Quentin Glidic]
- [NSE] Add http-server-header script to grab the Server header as a last-ditch effort to get a software version. This can\'t be done as a softmatch because of the need to match non-HTTP services that obey some HTTP requests. [Daniel Miller]
- [NSE] Add rfc868-time script to get the date and time from an RFC 868 Time server. [Daniel Miller]
- [NSE] Add weblogic-t3-info script that detects the T3 RMI protocol used by Oracle/BEA Weblogic. Extracts the Weblogic version, as well [Alessandro Zanni, Daniel Miller]
- Fixed a bug in libdnet with handling interfaces with AF_LINK addresses on FreeBSD >9 reported by idwer on IRC. Likely affected other *BSDs. Handled by skipping these non-network addresses. [Daniel Miller]
- Fixed a bug with UDP checksum calculation. When the UDP checksum is zero (0x0000), it must be transmitted as 1\'s-complement -0 (0xffff) to avoid ambiguity with...
Publisher review:Nmap is used to explore and perform an audit or a computer network hardware inventory. Network administrators can use to identify the network status, manage schedules update services and monitor the availability of each item. Nmap determines which hosts are on the network, the services they offer, on what operating systems, etc.. Designed to scan large networks, the application works perfectly on single target. Nmap features a functional graphical user interface that provides access to a wealth of information at the first glance.
Nmap supports ping scanning (determine which hosts are up), version detection (determine what application/service is runing on a port), many port scanning techniques (determine what services the hosts are offering), and TCP/IP fingerprinting.
Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.
Nmap was designed to rapidly scan large networks, but works fine against single hosts.
Nmap runs on all major computer operating systems, and both console and graphical versions are available.
Requirements:Operating system:Mac OS X 10.6 or later
