Nmap

Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.

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. It was designed to rapidly scan large networks, but works fine against single hosts.

- [Ndiff] Added support for prerule and postrule scripts.
- [NSE] Fixed a bug which caused some NSE scripts to fail due to the absence of the NSE SCRIPT_NAME environment variable when loaded. Michael Pattrick reported the problem.
- [Zenmap] Selecting one of the scan targets in the left pane is supposed to jump to that host in the Nmap Output in the right pane (but it wasn't).
- Fixed an obscure bug in Windows interface matching. If the MAC address of an interface couldn't be retrieved, it might have been used instead of the correct interface.
- [NSE] Fixed portrules in dns-zone-transfer and ftp-proftpd-backdoor that used shortport functions incorrectly and always returned true.
- [Ndiff] Fixed ndiff.dtd to include two elements that can be diffed: status and address.
- [Ndiff] Fixed the ordering of hostscript-related elements in XML output.
- [NSE] Fixed a bug in the nrpe-enum script that would make it run for every port (when it was selected--it isn't by default).
- [NSE] When an NSE script sets a negative socket timeout, it now causes a controlled Lua stack trace instead of a fatal error.
- [Zenmap] Worked around an error that caused the py2app bootstrap executable to be non-universal even when the rest of the application was universal. This prevented the binary .dmg from working on PowerPC.
- [Ndiff] Fixed an output line that wasn't being redirected to a file when all other output was.
