Download Nmap 4.52

Nmap is a program for exploring and monitoring a network. It’s designed to scan a large network without delays, but it also runs smoothly on a single host. The program uses so-called ‘raw ip packets’ to find out the active hosts and information about the available services. For more information about the possibilities, we refer you to this page. As a New Year’s gift, the developers have released version 4.52 in the stable branch. This fixes some minor installation bugs on Windows Vista and addresses several other issues. The list of changes looks like this:

Version 4.52:

• Fixed Nmap Winpcap installer to use CurrentVersion registry key on Windows rather than VersionNumber to more reliably detect Vista machines. This should prevent the XP version of Packet.dll from being installed on Vista.
• The Nmap Scripting Engine (NSE) now supports run-time interaction and the Nmap –host-timeout option.
• Added nmap.fetchfile() function for scripts so they can easily find Nmap’s nmap-* data files (such as the OS/version detection DBs, port number mapping, etc.)
• Updated rpcinfo.nse to use nmap.fetchfile() to read from nmap-rpc instead of having a huge table of RPC numbers. This reduced the script’s size by nearly 75%.
• Fixed multiple NSE scripts that weren’t always properly closing their sockets. The error message was: “bad argument #1 to ‘close’ (nsock expected, got no value)”
• Added a new version detection probe for the Trend Micro OfficeScan product line.

Version 4.51 BETA:

• We now have a detailed Zenmap Guide at http://insecure.org/nmap/zenmapguide/. Thanks to David for writing it.
• Added rpcinfo.nse script, which contacts a listening RPC portmapper and reports the listening services and port information (like rpcinfo -p does). The script was written by Sven Klemm. Fyodor then enhanced the RPC number list with all of the entries from nmap-rpc.
• Added a new NSE script (MySQLinfo) which prints MySQL server information such as the protocol and version numbers, status, thread id, capabilities, and password salt.
• Nmap’s output options (-oA, -oX, etc.) now support strftime()-like conversions in the filename. %H, %M, %S, %m, %d, %y, and %Y are all the same as in strftime(). %T is the same as %H%M%S, %R is the same as %H%M, and %D is the same as %m%d%y. A % followed by any other character just yields that character (%% yields a %). This means that “-oX ‘scan-%T-%D.xml'” uses an XML file in the form of “scan-144840-121307.xml”.
• Fixed Winpcap installer to install the right version of Packet.dll on Windows Vista.
• Fixed our Winpcap installer so that it waits for a Winpcap uninstall (if needed) to complete before trying to install the new Winpcap.
• Fix a bunch of warning/error messages which contained an extra newline.
• Fixed an error when attempting to scan localhost as an unprivileged user on Windows (nmap –unprivileged localhost). The error was: “Skipping SYN Stealth Scan against localhost (127.0.0.1) because Windows does not support scanning your own machine (localhost) this way.” Now connect scan is used instead of SYN scan.
• Fixed a bug that prevented the –resume option from working on Windows. The error message was: ..\utils.cc(996): CreateFileMapping(), file ‘testresume’, length 103, mflags 000 00006: The parameter is incorrect.(87)
• Zenmap’s new web page is now shown in the Zenmap about dialogue.
• On Windows, paths beginning with \ are now considered absolute when used with the –script option. jah (jah(a)zadkiel.plus.com) suggested this.
• Zenmap no longer double-spaces its output (by inadvertently duplicating newlines) when viewing scan results that were saved to a file.
• Upgraded the shipped LibPCRE from version 7.2 to 7.4.
• Fixed Zenmap crash that occurred when selecting Help from the Compare Results window.
• Updated robots.nse to prevent printing robots.txt comments.
• Many version detection match lines were improved to match even when newlines appear in binary data returned by the service.
