    NMAP 3.75 Released..

    From Fyodor.....

    Nmap hackers,

    I am pleased to release Nmap 3.75, which contains dozens of improvements over 3.70. One of the most important is a huge OS fingerprint database -- I finally got off my duff and integrated the latest submissions you guys have contributed. We're talking OpenBSD 3.6, WinXP SP2, Windows Longhorn warez, and hundreds more.

    I also fixed several errors that could cause the Windows version to crash, as well as some cross-platform issues. A new --max_scan_delay parameter is available for optimizing scn time. -T4 and -T5 are faster now as well. Here are the CHANGELOG details:

    o Implemented a huge OS fingerprint database update. The number of
    signatures have increased more than 20% to 1,353 and many of the
    existing ones are much improved. Notable updates include the fourth
    edition of Bell Lab's Plan9, Grandstream's BugeTone 101 IP Phone,
    and Bart's Network Boot Disk 2.7 (which runs MS-DOS). Oh, and Linux
    kernels up to 2.6.8, dozens of new Windows fingerprints including XP
    SP2, the latest Longhorn warez, and many modified Xboxes, OpenBSD
    3.6, NetBSD up to 2.0RC4, Apple's AirPort Express WAP and OS X 10.3.3
    (Panther) release, Novell Netware 6.5, FreeBSD 5.3-BETA, a bunch of
    Linksys and D-Link consumer junk, the latest Cisco IOS 12.2
    releases, a ton of miscellaneous broadband routers and printers, and
    much more.

    o Updated nmap-mac-prefixes with the latest OUIs from the IEEE.
    [ ]

    o Updated nmap-protocols with the latest IP protocols from IANA
    [ ]

    o Added a few new Nmap version detection signatures thanks to a patch
    from Martin MaÚok (martin.macok(a)

    o Fixed a crash problem in the Windows version of Nmap, thanks to a
    patch from Ganga Bhavani GBhavani(a)

    o Fixed Windows service scan crashes that occur with the error message
    "Unexpected nsock_loop error. Error code 10022 (Unknown error)". It
    turns out that Windows does not allow select() calls with all three
    FD sets empty. Lame. The Linux select() man page even suggests
    calling "select with all three sets empty, n zero, and a non-null
    timeout as a fairly portable way to sleep with subsecond precision."
    Thanks to Gisle Vanem (giva(a) for debugging help.

    o Added --max_scan_delay parameter. Nmap will sometimes increase the
    delay itself when it detects many dropped packets. For example,
    Solaris systems tend to respond with only one ICMP port unreachable
    packet per second during a UDP scan. So Nmap will try to detect
    this and lower its rate of UDP probes to one per second. This can
    provide more accurate results while reducing network congestion, but
    it can slow the scans down substantially. By default (with no -T
    options specified), Nmap allows this delay to grow to one second per
    probe. This option allows you to set a lower or higher maximum.
    The -T4 and -T5 scan modes now limit the maximum scan delay for TCP
    scans to 10 and 5 ms, respectively.

    o Fixed a bug that prevented RPC scan (-sR) from working for UDP ports
    unless service detection (-sV) was used. -sV is still usually a
    better approach than -sR, as the latter ONLY handles RPC. Thanks to
    Stephen Bishop (sbishop(a) for reporting the problem and
    sending a patch.

    o Fixed nmap_fetchfile() to better find custom versions of data files
    such as nmap-services. Note that the implicitly read directory
    should be ~/.nmap rather than ~/nmap . So you may have to move any
    customized files you now have in ~/nmap . Thanks to nnposter
    (nnposter(a) for reporting the problem and
    sending a patch.

    o Changed XML output so that the MAC address [address] element comes
    right after the IPv4/IPv6 [address] element. Apparently this is
    needed to comply with the DTD ( ). Thanks to Adam Morgan
    (adam.morgan(a) and Florian Ebner
    (Florian.Ebner(a) for the problem reports.

    o Fixed an error in the Nmap RPM spec file reported by Pascal Trouvin

    o Fixed a timing problem in which a specified large --send_delay would
    sometimes be reduced to 1 second during a scan. Thanks to Martin
    MaÚok (martin.macok(a) for reporting the problem.

    o Fixed a timing problem with sneaky and paranoid modes (-T1 and -T0)
    which would cause Nmap to continually scan the same port and never
    hit other ports when scanning certain firewalled hosts. Thanks to
    Curtis Doty (Curtis(a) for reporting the problem.

    o Fixed a bug in the build system that caused most Nmap subdirectories
    to be configured twice. Changing the variable holding the name of
    subdirs from $subdirs to $nmap_cfg_subdirs resolved the problem --
    configure must have been using that variable name for its own internal
    operations. Anyway, this should reduce compile time significantly.

    o Made a trivial change to nsock/src/nsock_event.c to work around a "a
    bug in GCC 3.3.1 on FreeBSD/sparc64". I found the patch by digging
    around the FreeBSD ports tree repository. It would be nice if the
    FreeBSD Nmap port maintainers would report such things to me, rather
    than fixing it in their own Nmap tree and then applying the patch to
    every future version. On the other hand, they deserve some sort of
    "most up-to-date" award. I stuck Nmap 3.71-PRE1 in the dist
    directory for a few people to test, and made no announcement or
    direct link. The FreeBSD crew found it and upgraded anyway . The
    gcc-workaround patch was apparently submitted to the FreeBSD folks
    by Marius Strobl (marius(a)

    o Fixed (I hope) an OS detection timing issue which would in some
    cases lead to the warning that "insufficient responses for TCP
    sequencing (3), OS detection may be less accurate." Thanks to Adam
    Kerrison (adam(a) for reporting the problem.

    o Modified the warning given when files such as nmap-services exist in
    both the compiled in NMAPDATADIR and the current working directory.
    That message should now only appear once and is more clear.

    o Fixed ping scan subsystem to work a little bit better when
    --scan_delay (or some of the slower -T templates which include a scan
    delay) is specified. Thanks to Shahid Khan (khan(a)
    for suggestions.

    o Taught connect() scan to properly interpret ICMP protocol
    unreachable messages. Thanks to Alan Bishoff
    (abishoff(a) for the report.

    o Improved the nmapfe.desktop file to better comply with standards.
    Thanks to Stephane Loeuillet (stephane.loeuillet(a) for
    sending the patch.

    As usual, 3.75 is available from, including Windows (.zip format) binaries.

    Thanks for the news. I'm waiting for the Debian ARM package so I can update my Zaurus web site.

    How do you get this to work for windows.

    You have to download the win32 binary.

    Unzip it to the directory of your choice and use it from the command line.

    There is a GUI frontend for nmap. It's called nmapFE.

    I wish that all developers were as fast at puting out updates as the boys over at, especially for utilities that cost money. As always, thank you for keeping us updated on this TheHorse.

    The other link for Nmap win interface, I am not able to download. Can anyone provide me an alternative site for downloading win interface Nmap.

    Thank you

    Why would you want to use the gui version..
    the commandline version works (atleast) as well !!
    The whole windows version works a lot less well then the unix version anyway..

    Also did you install the libpcap for windows stuff ??
    ASCII stupid question, get a stupid ANSI.

    And to all nmap win users, remember that most Nmap functionality will not work on XP SP2.
