o [Ndiff] Added support for prerule and postrule scripts.
o [NSE] Fixed a bug which caused some NSE scripts to fail due to the
absence of the NSE SCRIPT_NAME environment variable when loaded.
o [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).
o 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.
o [NSE] Fixed portrules in dns-zone-transfer and ftp-proftpd-backdoor
that used shortport functions incorrectly and always returned
true.
o [Ndiff] Fixed ndiff.dtd to include two elements that can be diffed:
status and address.
o [Ndiff] Fixed the ordering of hostscript-related elements in XML
output.
o [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).
o [NSE] When an NSE script sets a negative socket timeout, it now
causes a controlled Lua stack trace instead of a fatal error.
o [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.
o [Ndiff] Fixed an output line that wasn't being redirected to a file
when all other output was.
Some of the highlights are:
o [Zenmap] Added a new script selection interface, allowing you to
choose scripts and arguments from a list.
o [Nping] Added echo mode, learn more about echo mode at
http://nmap.org/book/nping-man-echo-mode.html.
o [NSE] Added an amazing 46 scripts, bringing the total to 177!
You can learn more about any of them at http://nmap.org/nsedoc/
o [NSE] Added 12 new protocol libraries.
o [NSE] Added a new brute library that provides a basic framework and logic
for brute force password auditing scripts.
o [Zenmap] Greatly improved performance for large scans by
benchmarking intensively and then recoding dozens of slow parts.
o Performed a major OS detection integration run. The database has
grown more than 14% to 2,982 fingerprints and many of the existing
fingerprints were improved. David posted highlights of his integration work at
http://seclists.org/nmap-dev/2010/q4/651
o Performed a huge version detection integration run. The number of
signatures has grown by more than 11% to 7,355. David posted highlights at
http://seclists.org/nmap-dev/2010/q4/761
o [NSE] Nmap has two new NSE script scanning phases. See
http://nmap.org/book/nse-usage.html#nse-script-types
o Dramatically improved nmap.xsl (used for converting Nmap XML output
to HTML).
o Integrated cracked passwords from the Gawker.com compromise
(http://seclists.org/nmap-dev/2010/q4/674) into Nmap's top-5000
password database.
o Merged port names in the nmap-services file with allocated names
from the IANA (http://www.iana.org/assignments/port-numbers).
o [Zenmap] Made the topology node radiuses grow logarithmically
instead of linearly, so that hosts with thousands of open ports
don't overwhelm the diagram.
o Improved IPv6 host output in that we now remember and report the
forward DNS name (given by the user) and any non-scanned addresses
(usually because of round robin DNS).
o [Zenmap] Upgraded to the newer gtk.Tooltip API to avoid deprecation
messages about gtk.Tooltip.
o [NSE] Enhance ssl-cert to also report the type and bit size of SSL
certificate public keys.
o [Nping] Nping now limits concurrent open file descriptors properly
based on the resources available on the host.
o Ncat now logs Nsock debug output to stderr instead of stdout for
consistency with its other debug messages.
o Changed the name of libdnet's sctp_chunkhdr to avoid a conflict with
a struct of the same name in <netinet/sctp.h>.
o [NSE] Host tables now have a host.traceroute member available when
--traceroute is used.
o Nmap now prints the MTU for interfaces in --iflist output.
o [Ncat,NSE] Server Name Indication (SNI) is now supported by Ncat and
Nmap NSE, allowing them to connect to servers which run multiple SSL
websites on one IP address.
o [Nsock] Added a new function, nsi_set_hostname, to set the intended
hostname of the target.
o [NSE] Made sslv2.nse give special output when SSLv2 is supported,
but no SSLv2 ciphers are offered.
o Fixed the fragmentation options (-f in Nmap, --mtu in Nmap & Nping),
which were improperly sending whole packets in version 5.35DC1.
o [NSE] When receiving raw packets from Pcap, the packet capture time
is now available to scripts as an additional return value from
pcap_receive().
o Updated IANA IP address space assignment list for random IP (-iR)
generation.
o [Ncat] Ncat now uses case-insensitive string comparison when
checking authentication schemes and parameters.
o [NSE] There is now a limit of 1,000 concurrent running scripts,
instituted to keep memory under control when there are many open
ports.
Plus many bugfixes and improvements.
For full changelog, see http://nmap.org/changelog.html

o Performed a major OS detection integration run.
o Performed a large version detection integration run.
o [Zenmap] Added the ability to print Nmap output to a printer.
o [Nmap, Ncat, Nping] The default unit for time specifications is now
seconds, not milliseconds, and times may have a decimal point.
o Ports are now considered open during a SYN scan if a SYN packet
(without the ACK flag) is received in response.
o [Ncat] In listen mode, the --exec and --sh-exec options now accept a
single connection and then exit, just like in normal listen mode.
o UDP payloads are now stored in an external data file, nmap-payloads,
instead of being hard-coded in the executable.
o Added a new library, libnetutil, which contains about 2,700 lines of
networking related code which is now shared between Nmap and Nping

prints the connecting source port along with the IP address.
o Added EPROTO to the list of known error codes in service scan.
o Updated IANA IP address space assignment list for random IP (-iR)
generation.
o Zenmap's "slow comprehensive scan profile" has been modified to use
the best 7-probe host discovery combination we were able to find in
extensive empirical testing

format or (as before) as XML.
o [NSE] Raw packet sending at the IP layer is now supported, in
addition to the existing Ethernet sending functionality.

Ok'ed during freeze by wiz@
Fix for PR#41506
Fix missing @dirrm entries from PLIST*
Before we go into the detailed changes, here are the top 5 improvements in Nmap 5:
1. The new Ncat tool aims to be your Swiss Army Knife for data transfer, redirection, and debugging. We released a whole users' guide detailing security testing and network administration tasks made easy with Ncat.
2. The addition of the Ndiff scan comparison tool completes Nmap's growth into a whole suite of applications which work together to serve network administrators and security practitioners. Ndiff makes it easy to automatically scan your network daily and report on any changes (systems coming up or going down or changes to the software services they are running). The other two tools now packaged with Nmap itself are Ncat and the much improved Zenmap GUI and results viewer.
3. Nmap performance has improved dramatically. We spent last summer scanning much of the Internet and merging that data with internal enterprise scan logs to determine the most commonly open ports. This allows Nmap to scan fewer ports by default while finding more open ports. We also added a fixed-rate scan engine so you can bypass Nmap's congestion control algorithms and scan at exactly the rate (packets per second) you specify.
4. We released Nmap Network Scanning, the official Nmap guide to network discovery and security scanning. From explaining port scanning basics for novices to detailing low-level packet crafting methods used by advanced hackers, this book suits all levels of security and networking professionals. A 42-page reference guide documents every Nmap feature and option, while the rest of the book demonstrates how to apply those features to quickly solve real-world tasks. More than half the book is available in the free online edition.
5. The Nmap Scripting Engine (NSE) is one of Nmap's most powerful and flexible features. It allows users to write (and share) simple scripts to automate a wide variety of networking tasks. Those scripts are then executed in parallel with the speed and efficiency you expect from Nmap. All existing scripts have been improved, and 32 new ones added. New scripts include a whole bunch of MSRPC/NetBIOS attacks, queries, and vulnerability probes; open proxy detection; whois and AS number lookup queries; brute force attack scripts against the SNMP and POP3 protocols; and many more. All NSE scripts and modules are described in the new NSE documentation portal.
Details are here: http://nmap.org/changelog.html
Correct handling of the length of data returned by SIOCGIFCONF. The
actual length of each item is never less than sizeof(struct ifreq), but
may be more than that. If the platform's struct sockaddr has an sa_len
field, and if the length in sa_len is larger then the space available in
ifr_ifru, then the data extends beyond the end of the ifr_ifru field by
the difference in sizes.

*Lots* of Zenmap fixes
See CHANGELOG for all the details
Take MAINTAINER (agreed with salo@)
o Updated to include the latest MAC Address prefixes from the IEEE in
nmap-mac-prefixes [Fyodor]
o NSE engine was cleaned up significantly.
o Nmap now understands the RFC 4007 percent syntax for IPv6 Zone IDs.
o Updated IANA assignment IP list for random IP (-iR)
generation. [Kris]
o NmapFE is now gone. (zenmap is the replacement)
o Added the NSE library (NSELib) which is a library of useful
functions (which can be implemented in LUA or as loadable C/C++
modules) for use by NSE scripts.
o Integrated the Nmap Scripting Engine (NSE) into mainline Nmap.
Changes:
4.20
o Integrated the latest OS fingerprint submissions. The 2nd
generation DB size has grown to 231 fingerprints. Please keep them
coming! New fingerprints include Mac OS X Server 10.5 pre-release,
NetBSD 4.99.4, Windows NT, and much more.
o Fixed a segmentation fault in the new OS detection system
which was reported by Craig Humphrey and Sebastian Garcia.
o Fixed a TCP sequence prediction difficulty indicator bug. The index
is supposed to go from 0 ("trivial joke") to about 260 (OpenBSD).
But some systems generated ISNs so insecurely that Nmap went
berserk and reported a negative difficulty index. This generally
only affects some printers, crappy cable modems, and Microsoft
Windows (old versions). Thanks to Sebastian Garcia for helping me
track down the problem.
4.20RC2
o Integrated all of your OS detection submissions since RC1. The DB
has increased 13% to 214 fingerprints. Please keep them coming!
New fingerprints include versions of z/OS, OpenBSD, Linux, AIX,
FreeBSD, Cisco CatOS, IPSO firewall, and a slew of printers and
misc. devices. We also got our first Windows 95 fingerprint,
submitted anonymously of course :).
o Fixed (I hope) the "getinterfaces: intf_loop() failed" error which
was seen on Windows Vista. The problem was apparently in
intf-win32.c of libdnet (need to define MIB_IF_TYPE_MAX to
MAX_IF_TYPE rather than 32). Thanks to Dan Griffin
(dan(a)jwsecure.com) for tracking this down!
o Applied a couple minor bug fixes for IP options
support and packet tracing. Thanks to Michal Luczaj
(regenrecht(a)o2.pl) for reporting them.
o Incorporated SLNP (Simple Library Network Protocol) version
detection support. Thanks to Tibor Csogor (tibi(a)tiborius.net) for
the patch.
4.20RC1
o Fixed (I hope) a bug related to Pcap capture on Mac OS X. Thanks to
Christophe Thil for reporting the problem and to Kurt Grutzmacher
and Diman Todorov for helping to track it down.
o Integrated all of your OS detection submissions since ALPHA11. The
DB has increased 27% to 189 signatures. Notable additions include
the Apple Airport Express, Windows Vista RC1, OpenBSD 4.0, a Sony
TiVo device, and tons of broadband routers, printers, switches, and
Linux kernels. Keep those submissions coming!
o Upgraded the included LibPCRE from version 6.4 to 6.7. Thanks to
Jochen Voss (voss(a)seehuhn.de) for the suggestion (he found some bugs
in 6.4)
4.20ALPHA11
o Integrated all of your OS detection submissions, bringing the
database up to 149 fingerprints. This is an increase of 28% from
ALPHA10. Notable additions include FreeBSD 6.1, a bunch of HP
LaserJet printers, and HP-UX 11.11. We also got a bunch of more
obscure submissions like Minix 3.1.2a and "Ember InSight Adapter for
programming EM2XX-family embedded devices". Who doesn't have a few
of those laying around? I'm hoping that all the obscure submissions
mean that more of the mainstream systems are being detected out of
the box! Please keep those submissions (obscure or otherwise)
coming!
4.20ALPHA10
o Integrated tons of new OS fingerprints. The DB now contains 116
fingerprints, which is up 63% since the previous version. Please keep
the submissions coming!
4.20ALPHA9
o Integrated the newly submitted OS fingerprints. The DB now contains
71 fingerprints, up 27% from 56 in ALPHA8. Please keep them coming!
We still only have 4.2% as many fingerprints as the gen1 database.
o Added the --open option, which causes Nmap to show only open ports.
Ports in the states "open|closed" and "unfiltered" might be open, so
those are shown unless the host has an overwhelming number of them.
o Nmap gen2 OS detection used to always do 2 retries if it fails to
find a match. Now it normally does just 1 retry, but does 4 retries
if conditions are good enough to warrant fingerprint submission.
This should speed things up on average. A new --max-os-tries option
lets you specify a higher lower maximum number of tries.
o Added --unprivileged option, which is the opposite of --privileged.
It tells Nmap to treat the user as lacking network raw socket and
sniffing privileges. This is useful for testing, debugging, or when
the raw network functionality of your operating system is somehow
broken.
o Fixed a confusing error message which occured when you specified a
ping scan or list scan, but also specified -p (which is only used for
port scans). Thanks to Thomas Buchanan for the patch.
o Applied some small cleanup patches from Kris Katterjohn
4.20ALPHA8
o Integrated the newly submitted OS fingerprints. The DB now contains
56, up 33% from 42 in ALPHA7. Please keep them coming! We still only
have 3.33% as many signatures as the gen1 database.
o Nmap 2nd generation OS detection now has a more sophisticated
mechanism for guessing a target OS when there is no exact match in the
database (see http://insecure.org/nmap/osdetect/osdetect-guess.html )
o Rewrote mswin32/nmap.rc to remove cruft and hopefully reduce some
MFC-related compilation problems we've seen. Thanks to KX
(kxmail(a)gmail.com) for doing this.
o NmapFE now uses a spin button for verbosity and debugging options so
that you can specify whatever verbosity (-v) or debugging (-d) level
you desire. The --randomize-hosts option was also added to NmapFE.
Thanks to Kris Katterjohn for the patches.
o A dozen or so small patches to Nmap and NmapFE by Kris Katterjohn.
o Removed libpcap/Win32 and libpcap/msdos as Nmap doesn't use them.
This reduces the Nmap tar.bz2 by about 50K. Thanks to Kris Katterjohn
for the suggestion.
4.20ALPHA7
o Did a bunch of Nmap 2nd generation fingerprint integration work.
Thanks to everyone who sent some in, though we still need a lot more.
Also thanks to Zhao for a bunch of help with the integration tools.
4.20ALPHA6 had 12 fingerprints, this new version has 42. The old DB
(still included) has 1,684.
o Updated nmap-mac-prefixes to reflect the latest OUI DB from the IEEE
(http://standards.ieee.org/regauth/oui/oui.txt) as of September 6, 2006.
Also added the unregistered PearPC virtual NIC prefix, as suggested
by Robert Millan (rmh(a)aybabtu.com).
o Applied some small internal cleanup patches by Kris Katterjohn.
4.20ALPHA6
o Fixed a bug in 2nd generation OS detection which would (usually) prevent
fingerprints from being printed when systems don't respond to the 1st
ICMP echo probe (the one with bogus code value of 9). Thanks to
Brandon Enright for reporting and helping me debug the problem.
o Fixed some problematic Nmap version detection signatures which could
cause warning messages. Thanks to Brandon Enright for the initial patch.
4.20ALPHA5
o Worked with Zhao to improve the new OS detection system with
better algorithms, probe changes, and bug fixes. We're
now ready to start growing the new database! If Nmap gives you
fingerprints, please submit them at the given URL. The DB is still
extremely small. The new system is extensively documented at
http://insecure.org/nmap/osdetect/ .
o Nmap now supports IP options with the new --ip-options flag. You
can specify any options in hex, or use "R" (record route), "T"
(record timestamp), "U") (record route & timestamp), "S [route]"
(strict source route), or "L [route]" (loose source route). Specify
--packet-trace to display IP options of responses. For further
information and examples, see http://insecure.org/nmap/man/ and
http://seclists.org/nmap-dev/2006/q3/0052.html . Thanks to Marek
Majkowski for writing and sending the patch.
o Integrated all 2nd quarter service detection fingerprint
submissions. Please keep them coming! We now have 3,671 signatures
representing 415 protocols. Thanks to version detection czar Doug
Hoyte for doing this.
o Nmap now uses the (relatively) new libpcap pcap_get_selectable_fd
API on systems which support it. This means that we no longer need
to hack the included Pcap to better support Linux. So Nmap will now
link with an existing system libpcap by default on that platform if
one is detected. Thanks to Doug Hoyte for the patch.
o Updated the included libpcap from 0.9.3 to 0.9.4. The changes I
made are in libpcap/NMAP_MODIFICATIONS . By default, Nmap will now
use the included libpcap unless version 0.9.4 or greater is already
installed on the system.
o Applied some nsock bugfixes from Diman Todorov. These don't affect
the current version of Nmap, but are important for his Nmap
Scripting Engine, which I hope to integrate into mainline Nmap in
September.
o Fixed a bug which would occasionally cause Nmap to crash with the
message "log_vwrite: write buffer not large enough". I thought I
conquered it in a previous release -- thanks to Doug Hoyte for finding a
corner case which proved me wrong.
o Fixed a bug in the rDNS system which prevented us from querying
certain authoritative DNS servers which have recursion explicitly
disabled. Thanks to Doug Hoyte for the patch.
o --packet-trace now reports TCP options (thanks to Zhao Lei for the
patch). Thanks to the --ip-options addition also found in this
release, IP options are printed too.
o Cleaned up Nmap DNS reporting to be a little more useful and
concise. Thanks to Doug Hoyte for the patch.
o Applied a bunch of small internal cleanup patches by Kris Katterjohn
(kjak(a)ispwest.com).
o Fixed the 'distclean' make target to be more comprehensive. Thanks
to Thomas Buchanan (Thomas.Buchanan(a)thecompassgrp.net) for the
patch.
Nmap 4.20ALPHA4
o Nmap now provides progress statistics in the XML output in verbose
mode. Here are some examples of the format (etc is "estimated time
until completion) and times are in UNIX time_t (seconds since 1970)
format. Angle braces have been replaced by square braces:
[taskbegin task="SYN Stealth Scan" time="1151384685" /]
[taskprogress task="SYN Stealth Scan" time="1151384715"
percent="13.85" remaining="187" etc="1151384902" /]
[taskend task="SYN Stealth Scan" time="1151384776" /]
[taskbegin task="Service scan" time="1151384776" /]
[taskend task="Service scan" time="1151384788" /]
Thanks to Adam Vartanian (flooey(a)gmail.com) for the patch.
o Updated the Windows installer to give an option checkbox for
performing the Nmap performance registry changes. The default is to
do so. Thanks to Adam Vartanian (flooey(a)gmail.com) for the patch.
o Applied several code cleanup patches from Marek Majkowski.
o Added --release-memory option, which causes Nmap to release all
accessible memory buffers before quitting (rather than let the OS do
it). This is only useful for debugging memory leaks.
o Fixed a bug related to bogus completion time estimates when you
request an estimate (through runtime interaction) right when Nmap is
starting.a subsystem (such as a port scan or version detection).
Thanks to Diman Todorov for reporting the problem and Doug Hoyte for
writing a fix.
o Nmap no longer gets random numbers from OpenSSL when it is available
because that turned out to be slower than Nmap's other methods
(e.g. /dev/urandom on Linux, /dev/arandom on OpenBSD, etc.). Thanks
to Marek Majkowski for reporting the problem.
o Updated the Windows binary distributions (self-installer and .zip)
to include the new 2nd generation OS detection DB (nmap-os-db).
Thanks to Sina Bahram for reporting the problem.
o Fixed the --max-retries option, which wasn't being honored. Thanks
to Jon Passki (jon.passki(a)hursk.com) for the patch.
Nmap 4.20ALPHA3
o Added back Win32 support thanks to a patch by kx
o Fixed the English translation of TCP sequence difficulty reported by
Brandon Enright, and also removed fingerprint printing for 1st
generation fingerprints (I don't really want to deal with those
anymore). Thanks to Zhao Lei for writing this patch.
o Fix a problem which caused OS detection to be done in some cases
even if the user didn't request it. Thanks to Diman Todorov for the
fix.
Nmap 4.20ALPHA2
o Included nmap-os-db (the new OS detection DB) within the release.
Oops! Thanks to Brandon Enright (bmenrigh(a)ucsd.edu) for catching
this problem with 4.20ALPHA1.
o Added a fix for the crash in the new OS detection which would come
with the message "Probe doesn't exist! Probe type: 1. Probe subid: 1"
Nmap 4.20ALPHA1
o Integrated initial 2nd generation OS detection patch! The system is
documented at http://insecure.org/nmap/osdetect/ . Thanks to Zhao Lei
for helping with the coding and design.
o portlist.cc was refactored to remove some code duplication. Thanks
to Diman Todorov for the patch.
set OVERRIDE_DIRDEPTH to find any libtool scripts deeper in the WRKSRC
tree unless they're named something other than "libtool".
SHLIBTOOL_OVERRIDE generally doesn't need to be specified either -- just
define it to the empty list and shlibtool-override will look for libtool
scripts.
- bite the bullet and use GNU make, it's increasingly annoying to try
avoiding it
Changes:
- Added a dozens of more detailed SSH version detection signatures,
thanks to a SSH huge survey and integration effort by Doug Hoyte.
The results of his large-scale SSH scan are posted at
http://seclists.org/nmap-dev/2006/Apr-Jun/0393.html .
- Fixed the Nmap Makefile (actually Makefile.in) to correctly handle
include file dependencies. So if a .h file is changed, all of the
.cc files which depend on it will be recompiled. Thanks to Diman
Todorov (diman(a)xover.mud.at) for the patch.
- Fixed a compilation problem on solaris and possibly other platforms.
The error message looked like "No rule to make target `inet_aton.o',
needed by `libnbase.a'". Thanks to Matt Selsky
(selsky(a)columbia.edu) for the patch.
Fixes PR pkg/33806 from Gilles Dauphin.
- Applied a patch which helps with HP-UX compilation by linking in the
nm library (-lnm). Thanks to Zakharov Mikhail (zmey20000(a)yahoo.com)
for the patch.
- Added version detection probes for detecting the Nessus daemon.
Thanks to Adam Vartanian (flooey(a)gmail.com) for sending the patch.
Changes:
4.10:
=====
- Updated nmap-mac-prefixes to reflect the latest OUI DB from the IEEE
(http://standards.ieee.org/regauth/oui/oui.txt) as of May 31, 2006.
Also added a couple unregistered OUI's (for QEMU and Bochs)
suggested by Robert Millan (rmh(a)aybabtu.com).
- Fixed a bug which could cause false öpen" ports when doing a UDP
scan of localhost. This usually only happened when you scan tens of
thousands of ports (e.g. -p- option).
- Fixed a bug in service detection which could lead to a crash when
"--version-intensity 0" was used with a UDP scan. Thanks to Makoto
Shiotsuki (shio(a)st.rim.or.jp) for reporting the problem and Doug
Hoyte for producing a patch.
- Made some AIX and HP-UX portability fixes to Libdnet and NmapFE.
These were sent in by Peter O'Gorman
(nmap-dev(a)mlists.thewrittenword.com).
- When you do a UDP«CP scan, the TCP ports are now shown first (in
numerical order), followed by the UDP ports (also in order). This
contrasts with the old format which showed all ports together in
numerical order, regardless of protocol. This was at first a "bug",
but then I started thinking this behavior may be better. If you
have a preference for one format or the other, please post your
reasons to nmap-dev.
- Changed mass_dns system to print a warning if it can't find any
available DNS servers, but not quit like it used to. Thanks to Doug
Hoyte for the patch.
4.04BETA1:
==========
- Integrated all of your submissions (about a thousand) from the first
quarter of this year! Please keep 'em coming! The DB has increased
from 3,153 signatures representing 381 protocols in 4.03 to 3,441
signatures representing 401 protocols. No other tool comes close!
Many of the already existing match lines were improved too. Thanks
to Version Detection Czar Doug Hoyte for doing this.
- Nmap now allows multiple ingored port states. If a 65K-port scan
had, 64K filtered ports, 1K closed ports, and a few dozen open
ports, Nmap used to list the dozen open ones among a thousand lines
of closed ports. Now Nmap will give reports like "Not shown: 64330
filtered ports, 1000 closed ports" or "All 2051 scanned ports on
192.168.0.69 are closed (1051) or filtered (1000)", and omit all of
those ports from the table. Open ports are never ignored. XML
output can now have multiple <extraports> directive (one for each
ignored state). The number of ports in a single state before it is
consolidated defaults to 26 or more, though that number increases as
you add -v or -d options. With -d3 or higher, no ports will be
consolidated. The XML output should probably be augmented to give
the extraports directive 'ip', 'tcp', and 'udp' attributes which
specify the corresponding port numbers in the given state in the
same listing format as the nmaprun.scaninfo.services attribute, but
that part hasn't yet been implemented. If you absoultely need the
exact port numbers for each state in the XML, use -d3 for now.
- Nmap now ignores certain ICMP error message rate limiting (rather
than slowing down to accomidate it) in cases such as SYN scan where
an ICMP message and no response mean the same thing (port filtered).
This is currently only done at timing level Aggressive (-T4) or
higher, though we may make it the default if we don't hear problems
with it. In addition, the --defeat-rst-ratelimit option has been
added, which causes Nmap not to slow down to accomidate RST rate
limits when encountered. For a SYN scan, this may cause closed
ports to be labeled 'filtered' becuase Nmap refused to slow down
enough to correspond to the rate limiting. Learn more about this
new option at http://www.insecure.org/nmap/man/ . Thanks to Martin
Macok (martin.macok(a)underground.cz) for writing the patch that
these changes were based on.
- Moved my Nmap development environment to Visual C++ 2005 Express
edition. In typical "MS Upgrade Treadmill" fashion, Visual Studio
2003 users will no longer be able to compile Nmap using the new
solution files. The compilation, installation, and execution
instructions at
http://www.insecure.org/nmap/install/inst-windows.html have been
upgraded.
- Automated my Windows build system so that I just have to type a
single make command in the mswin32 directory. Thanks to Scott
Worley (smw(a)pobox.com>, Shane & Jenny Walters
(yfisaqt(a)waltersinamerica.com), and Alex Prinsier
(aphexer(a)mailhaven.com) for reading my appeal in the 4.03
CHANGELOG and assisting.
- Changed the PortList class to use much more efficient data
structures and algorithms which take advantage of Nmap-specific
behavior patterns. Thanks to Marek Majkowski
(majek(a)forest.one.pl) for the patch.
- Fixed a bug which prevented certain TCPÙDP scan commands, such as
"nmap -sSU -p1-65535 localhost" from scanning both TCP and UDP.
Instead they gave the error message "WARNING: UDP scan was requested,
but no udp ports were specified. Skipping this scan type". Thanks to
Doug Hoyte for the patch.
- Nmap has traditionally required you to specify -T* timing options
before any more granular options like --max-rtt-timeout, otherwise the
general timing option would overwrite the value from your more
specific request. This has now been fixed so that the more specific
options always have precendence. Thanks to Doug Hoyte for this patch.
- Fixed a couple possible memory leaks reported by Ted Kremenek
(kremenek(a)cs.stanford.edu) from the Stanford University sofware
static analysis lab ("Checker" project).
- Nmap now prints a warning when you specify a target name which
resolves to multiple IP addresses. Nmap proceeds to scan only the
first of those addresses (as it always has done). Thanks to Doug
Hoyte for the patch. The warning looks like this:
Warning: Hostname google.com resolves to 3 IPs. Using 66.102.7.99.
- Disallow --host-timeout values of less than 1500ms, print a warning
for values less than 15s.
- Changed all instances of inet_aton() into calls to inet_pton()
instead. This allowed us to remove inet_aton.c from nbase. Thanks to
KX (kxmail(a)gmail.com) for the patch.
- When debugging (-d) is specified, Nmap now prints a report on the
timing variables in use. Thanks to Doug Hoyte for the patch. The
report loos like this:
---------- Timing report ----------
hostgroups: min 1, max 100000
rtt-timeouts: init 250, min 50, max 300
scan-delay: TCP 5, UDP 1000
parallelism: min 0, max 0
max-retries: 2, host-timeout 900000
-----------------------------------
- Modified the WinPcap installer file to explicitly uninstall an
existing WinPcap (if you select that you wish to replace it) rather
than just overwriting the old version. Thanks to Doug Hoyte for
making this change.
- Added some P2P application ports to the nmap-services file. Thanks
to Martin Macok for the patch.
- The write buffer length increased in 4.03 was increased even further
when the debugging or verbosity levels are more than 2 (e.g. -d3).
Thanks to Brandon Enright (bmenrigh(a)ucsd.edu) for the patch. The
goal is to prevent you from ever seeing the fatal error:
"log_vwrite: write buffer not large enough -- need to increase"
- Added a note to the Nmap configure dragon that people sick of him
can submit their own ASCII art to nmap-dev@insecure.org . If you
are wondering WTF I am talking about, it is probably because only
most elite Nmap users -- the ones who compile from source on UNIX --
get to see the 'l33t ASCII Art.
Changes:
- Updated the LibPCRE build system to add the -fno-thread-jumps option
to gcc when compiling on the new Intel-based Apple Mac OS X systems.
Hopefully this resolves the version detection crashes that several
people have reported on such systems. Thanks to Kurt Grutzmacher
(grutz(a)jingojango.net) for sending the configure.ac patch.
- Increased a write buffer length to avoid Nmap from quitting with the
message "log_vwrite: write buffer not large enough -- need to
increase". Thanks to Dave (dmarcher(a)pobox.com) for reporting the
issue.
- Made some portability fixes to keep Nmap compiling with the newest
Visual Studio 2005. Thanks to KX (kxmail(a)gmail.com) for
suggesting them.
- Service fingerprints are now provided in the XML output whenever
they would appear in the interactive output (i.e. when a service
respons with data but is unrecognized). They are shown in a new
'servicefp' attribute to the 'service' tag. Thanks to Brandon Enright
(bmenrigh(a)ucsd.edu) for sending the patch.
- Improved the Windows build system -- mswin32/Makefile now takes care
of packaging Nmap and creating the installers once Visual Studio (GUI)
is done building the Release version of mswin32/nmap.sln. If someone
knows how to do this (build) step on the command line (using the
Makefile), please let me know. Or if you know how to at least make
'Release' (rather than Debug) the default configuration, that would be
valuable.
- WinPcap 3.1 binaries are now shipped in the Nmap tarball, along with
a customized (for Nmap) installer written by Doug Hoyte. That new
WinPcap installer is now used in the Nmap self-installer.
- Fixed (I hope) a problem where aggresive --min-parallelization
option values could cause Nmap to quit with the message "box(300, 100,
15) called (min,max,num)". Thanks to Richard van den Berg
(richard.vandenberg(a)ins.com) for reporting the problem.
- Fixed a rare crash bug thanks to a report and patch from Ganga
Bhavani (GBhavani(a)everdreamcorp.com)
Changes:
- Fixed a bug that would cause bogus reverse-DNS resolution on
big-endian machines. Thanks to Doug Hoyte, Seth Miller, Tony Doan,
and Andrew Lutomirsky for helping to debug and patch the problem.
- Fixed an important memory leak in the raw ethernet sending system.
Thanks to Ganga Bhavani (GBhavani(a)everdreamcorp.com) for
identifying the bug and sending a patch.
- Fixed --system-dns option so that --system_dns works too. Error
messages were changed to reflect the former (preferred) name.
Thanks to Sean Swift (sean.swift(a)bradford.gov.uk) and Peter
VanEeckhoutte (Peter.VanEeckhoutte(a)saraleefoodseurope.com) for
reporting the problem.
- Fixed a crash which would report this message:
"NmapOutputTable.cc:143: void NmapOutputTable::addItem(unsigned int,
unsigned int, bool, const char*, int): Assertion `row < numRows'
failed." Thanks to Jake Schneider (Jake.Schneider(a)dynetics.com)
for reporting and helping to debug the problem.
- Whenever Nmap sends packets with the SYN bit set (except for OS
detection), it now includes the maximum segment size (MSS) tcp
option with a value of 1460. This makes it stand out less as almost
all hosts set at least this option. Thanks to Juergen Schmidt
(ju(a)heisec.de) for the suggestion.
- Applied a patch for a Windows interface reading bug in the aDNS
subsystem from Doug Hoyte.
- Minor changes to recognize DragonFly BSD in configure
scripts. Thanks to Joerg Sonnenberger (joerg(a)britannica.bec.de)
for sending the patch.
- Fixed a minor bug in an error message starting with "eth_send of ARP
packet returned". Thanks to J.W. Hoogervorst
(J.W.Hoogervorst(a)uva.nl) for finding this.
Changes:
4.00:
=====
- Added the '?' command to the runtime interaction system. It prints
a list of accepted commands. Thanks to Andrew Lutomirski
(luto(a)myrealbox.com) for the patch.
3.9999:
=======
- Generated a new libpcre/configure to cope with changes in LibPCRE
6.4
- Updated nmap-mac-prefixes to reflect the latest OUI DB from the IEEE
(http://standards.ieee.org/regauth/oui/oui.txt)
- Updated nmap-protocols with the latest IEEE internet protocols
assignments (http://www.iana.org/assignments/protocol-numbers).
- Updated the Nmap version number and related fields that MS Visual
Studio places in the binary. This was done by editing
mswin32/nmap.rc.
3.999:
======
- Added runtime interaction support to Windows, thanks to patches from
Andrew Lutomirski (luto(a)myrealbox.com) and Gisle Vanem
(giva(a)bgnett.no).
- Changed a couple lines of tcpip.cc (put certain IP header fields in
host byte order rather than NBO) to (hopefully) support Mac OS X on
Intel. Thanks to Kurt Grutzmacher (grutz(a)jingojango.net) for the
patch.
- Upgraded the included LibPCRE from version 6.3 to 6.4. There was a
report of version detection crashes on the new Intel-based MACs with
6.3.
- Fixed an issue in which the installer would malfunction in rare
issues when installing to a directory with spaces in it. Thanks to
Thierry Zoller (Thierry(a)Zoller.lu) for the report.
3.99:
=====
- Integrated all remaining 2005 service submissions. The DB now has
surpassed 3,000 signatures for the first time. There now are 3,153
signatures for 381 service protocols. Those protocols span the
gamut from abc, acap, afp, and afs to zebedee, zebra, and
zenimaging. It even covers obscure protocols such as http, ftp,
smtp, and ssh :). Thanks to Version Detection Czar Doug Hoyte for
his excellent work on this.
- Created a Windows executable installer using the open source NSIS
(Nullsoft Scriptable Install System). It handles Pcap installation,
registry performance changes, and adding Nmap to your cmd.exe
executable path. The installer source files are in mswin32/nsis/ .
Thanks to Google SoC student Bo Jiang (jiangbo(a)brandeis.edu) for
creating the initial version.
- Fixed a backward compatibility bug in which Nmap didn't recognize
the --min_rtt_timeout option (it only recognized the newly
hyphenated --min-rtt-timeout). Thanks to Joshua D. Abraham
(jabra(a)ccs.neu.edu) for the bug report.
- Fixed compilation to again work with gcc-derivatives such as
MingW. Thanks to Gisle Vanem (giva(a)bgnett.no) for sending the
patches
3.98BETA1:
==========
- Added run time interaction as documented at
http://www.insecure.org/nmap/man/man-runtime-interaction.html .
While Nmap is running, you can now press 'v' to increase verbosity,
'd' to increase the debugging level, 'p' to enable packet tracing,
or the capital versions (V,D,P) to do the opposite. Any other key
(such as enter) will print out a status message giving the estimated
time until scan completion. This only works on UNIX for now. Do we
have any volunteers to add Windows support? You would need to
change a handful of UNIX-specific termio calls with the Windows
equivalents. This feature was created by Paul Tarjan
(ptarjan(a)stanford.edu) as part of the Google Summer of Code.
- Reverse DNS resolution is now done in parallel rather than one at a
time. All scans of large networks (particularly list, ping and
just-a-few-ports scans) should benefit substantially from this
change. If you encounter any problems, please let us know. The new
--system_dns option was added so you can use the (slow) system
resolver if you prefer that for some reason. You can specify a
comma separated list of DNS server IP addresses for Nmap to use with
the new --dns_servers option. Otherwise, Nmap looks in
/etc/resolve.conf (UNIX) or the system registry (Windows) to obtain
the nameservers already configured for your system. This excellent
patch was written by Doug Hoyte (doug(a)hcsw.org).
- Added the --badsum option, which causes Nmap to use invalid TCP or
UDP checksums for packets sent to target hosts. Since virtually all
host IP stacks properly drop these packets, any responses received
are likely coming from a firewall or IDS that didn't bother to
verify the checksum. For more details on this technique, see
http://www.phrack.org/phrack/60/p60-0x0c.txt . The author of that
paper, Ed3f (ed3f(a)antifork.org), is also the author of this patch
(which I changed it a bit).
- The 26 Nmap commands that previously included an underscore
(--max_rtt_timeout, --send_eth, --host_timeout, etc.) have been
renamed to use a hyphen in the preferred format
(i.e. --max-rtt-timeout). Underscores are still supported for
backward compatibility.
- More excellent NmapFE patches from Priit Laes (amd(a)store20.com)
were applied to remove all deprecated GTK API calls. This also
eliminates the annoying Gtk-Critical and Gtk-WARNING runtime messages.
- Changed the way the __attribute__ compiler extension is detected so
that it works with the latest Fedora Core 4 updates (and perhaps other
systems). Thanks to Duilio Protti (dprotti(a)fceia.unr.edu.ar) for
writing the patch. The compilation error message this fixes was
usually something like: "nmap.o(.rodata+0x17c): undefined reference
to `__gthrw_pthread_cancel(unsigned long)"
- Added some exception handling code to mswin32/winfix.cc to prevent
Nmap from crashing mysteriously when you have WinPcap 3.0 or earlier
(instead of the required 3.1). It now prints an error message instead
asking you to upgrade, then reduces functionality to connect()-only
mode. I couldn't get it working with the C++ standard try/catch()
blocks, but as soon as I used the nonstandard MS conventions
(__try/__except(), everything worked fine. Shrug.
- Stripped the firewall API out of the libdnet included with Nmap
because Nmap doesn't use it anyway. This saves space and reduces the
likelihood of compilation errors and warnings.
- Modified the previously useless --noninteractive option so that it
deactivates runtime interaction.
3.96BETA1:
==========
- Added --max_retries option for capping the maximum number of
retransmissions the port scan engine will do. The value may be as low
as 0 (no retransmits). A low value can increase speed, though at the
risk of losing accuracy. The -T4 option now allows up to 6 retries,
and -T5 allows 2. Thanks to Martin Macok
(martin.macok(a)underground.cz) for writing the initial patch, which I
changed quite a bit. I also updated the docs to reflect this neat
new option.
- Many of the Nmap low-level timing options take a value in
milliseconds. You can now append an 's', 'm', or 'h' to the value
to give it in seconds, minutes, or hours instead. So you can specify
a 45 minute host timeout with --host_timeout 45m rather than specifying
--host_timeout 2700000 and hoping you did the math right and have the
correct number of zeros. This also now works for the
--min_rtt_timeout, --max_rtt_timeout, --initial_rtt_timeout,
--scan_delay, and --max_scan_delay options.
- Improved the NmapFE port to GTK2 so it better-conforms to the new
API and you don't get as many annoying messages in your terminal
window. GTK2 is prettier and more functional too. Thanks to Priit
Laes (amd(a)store20.com) for writing these
excellent patches.
- Fixed a problem which led to the error message "Failed to determine
dst MAC address for target" when you try to run Nmap using a
dialup/PPP adapter on Windows rather than a real ethernet card. Due
to Microsoft breaking raw sockets, Nmap no longer supports dialup
adapters, but it should now give you a clearer error message than
the "dst MAC address" nonsense.
- Debian GNU/kFreeBSD is now supported thanks to a patch to libdnet's
configure.in by Petr Salinger (Petr.Salinger(a)t-systems.cz).
- Tried to update to the latest autoconf only to find that there
hasn't been a new version in more than two years :(. I was able to
find new config.sub and config.guess files at
http://cvs.savannah.gnu.org/viewcvs/config/config/ , so I updated to
those.
- Fixed a problem with the -e option when run on Windows (or UNIX with
--send_eth) when run on an ethernet network against an external
(routed) host. You would get the message "NmapArpCache() can only
take IPv4 addresses. Sorry". Thanks to KX (kxmail(a)gmail.com) for
helping to track down the problem.
- Made some changes to allow source port zero scans (-g0). Nmap used
to refuse to do this, but now it just gives a warning that it may not
work on all systems. It seems to work fine on my Linux box. Thanks
to Bill Dale (bill_dale(a)bellsouth.net) for suggesting this feature.
- Made a change to libdnet so that Windows interfaces are listed as
down if they are disconnected, unplugged, or otherwise unavailable.
- Ceased including foreign translations in the Nmap tarball as they
take up too much space. HTML versions can be found at
http://www.insecure.org/nmap/docs.html , while XML and NROFF versions
are available from http://www.insecure.org/nmap/data/man-xlate/ .
- Changed INSTALL and README-WIN32 files to mostly just reference the
new Nmap Install Guide at http://www.insecure.org/nmap/install/ .
- Included docs/nmap-man.xml in the tarball distribution, which is the
DocBook XML source for the Nmap man page. Patches to Nmap that are
user-visible should include patches to the man page XML source rather
than to the generated Nroff.
- Fixed Nmap so it doesn't crash when you ask it to resume a previous
scan, but pass in a bogus file rather than actual Nmap output. Thanks
to Piotr Sobolewski (piotr_sobolewski(a)o2.pl) for the fix.
Changes:
- Put Nmap on a diet, with changes to the core port scanning routine
(ultra_scan) to substantially reduce memory consumption, particularly
when tens of thousands of ports are scanned.
- Wrote a new man page from scratch. It is much more comprehensive
(more than twice as long) and (IMHO) better organized than the
previous one. Read it online at http://www.insecure.org/nmap/man/
or docs/nmap.1 from the Nmap distribution. Let me know if you have
any ideas for improving it.
- Wrote a new "help screen", which you get when running Nmap without
arguments. It is also reproduced in the man page and at
http://www.insecure.org/nmap/data/nmap.usage.txt . I gave up trying
to fit it within a 25-line, 80-column terminal window. It is now 78
lines and summarizes all but the most obscure Nmap options.
- Removed foreign translations of the old man page from the
distribution. Included the following contributed translations
(nroff format) of the new man page:
Brazilian Portuguese by Lucien Raven (lucienraven(a)yahoo.com.br)
Portuguese (Portugal) by José Domingos (jd_pt(a)yahoo.com) and
Andreia Gaita (shana.ufie(a)gmail.com).
- Fixed a crash in IPID Idle scan. Thanks to Ron
(iago(a)valhallalegends.com>, Bakeman (bakeman(a)physics.unr.edu),
and others for reporting the problem.
- Applied some small fixes so that Nmap compiles with Visual C++
2005 Express, which is free from Microsoft at
http://msdn.microsoft.com/vstudio/express/visualc/ . Thanks to KX
(kxmail(a)gmail.com) and Sina Bahram (sbahram(a)nc.rr.com)
- Version detection softmatches (when Nmap determines the service
protocol such as smtp but isn't able to determine the app name such as
Postfix) can now parse out the normal match line fields such as
hostname, device type, and extra info. For example, we may not know
what vendor created an sshd, but we can still parse out the protocol
number. This was a patch from Doug Hoyte (doug(a)hcsw.org).
- Fixed a problem which caused UDP version scanning to fail to print
the matched service. Thanks to Martin Macok
(martin.macok(a)underground.cz) for reporting the problem and Doug
Hoyte (doug(a)hcsw.org) for fixing it.
- Made the version detection "ports" directive (in
nmap-service-probes) more comprehensive. This should speed up scans a
bit. The patch was done by Doug Hoyte (doug(a)hcsw.org).
- Integrated all of the September version detection fingerprint
submissions. This was done by Version Detection Czar Doug Hoyte
(doug(a)hcsw.org) and resulted in 86 new match lines. Please keep
those submissions coming!
- Fixed a bunch of typos and misspellings throughout the Nmap source
code (mostly in comments). This was a 625-line patch by Saint Xavier
(skyxav(a)skynet.be).
- Added the --webxml option, which does the same thing as
--stylesheet http://www.insecure.org/nmap/data/nmap.xsl , without
requiring you to remember the exact URL or type that whole thing.
- Fixed a possible aliasing problem in tcpip.cc by applying a patch sent in by
Gwenole Beauchesne (gbeauchesne(a)mandriva.com). This problem
shouldn't have had any effect on users since we already include the
-fno-strict-aliasing option whenever gcc 4 is detected, but it
brings us closer to being able to remove that option.
- Fixed a problem with the -S and -e options (spoof/set
source address, and set interface by name, respectively). The problem
report and a partial patch were sent by Richard Birkett
(richard(a)musicbox.net).
- Fixed a problem with the -S and option on Windows reporting "Failed
to resolve/decode supposed IPv4 source address". The -D (decoy)
option was probably broken on that platform too. Thanks to KX
(kxmail(a)gmail.com) for reporting the problem and tracking down a
potential solution.
- Added --thc option (undocumented)
- Modified libdnet-stripped/src/eth-bsd.c to allow for up to 128 bpf
devices rather than 32. This prevents errors like "Failed to open
ethernet interface (fxp0)" when there are more than 32 interface
aliases. Thanks to Krok (krok(a)void.ru) for reporting the problem
and even sending a patch.
- Fixed a minor syntax error in tcpip.h that was causing problems with
GCC 4.1. Thanks to Dirk Mueller (dmuell(a)gmx.net) for reporting
the problem and sending a fix.
- Define INET_ADDRSTRLEN in tcpip.h if the system doesn't define it
for us. This apparently aids compilation on Solaris 2.6 and 7.
Thanks to Albert Chin (nmap-hackers(a)mlists.thewrittenword.com) for
sending the patch..
- Fixed an inefficiency in RPC scan that could slow things down and
also sometimes resulted in the spurious warning message: Ünable to
find listening socket in get_rpc_results"
- Fixed a compilation problem on Mac OS X and perhaps other platforms
with a one-line fix to scan_engine.cc. Thanks to Felix Gröbert
(felix(a)groebert.org) for notifying me of the problem.
- Nmap now accepts target list files in Windows end-of-line format (\r\n)
as well as standard UNIX format (\n) on all platforms. Passing a
Windows style file to Nmap on UNIX didn't work before unless you ran
dos2unix first.
- Fixed a problem that prevented the command "nmap -sT -PT <targets>"
from working from a non-privileged user account. The -PT option
doesn't change default behavior in this case, but Nmap should (and now
does) allow it.
- Better handle ICMP type 3, code 0 (network unreachable) responses to
port scan packets. These are rarely seen when scanning hosts that
are actually online, but are still worth handling.
- Fixed a crash occured when the --exclude option was used with
netmasks on certain platforms. Thanks to Adam
(nmapuser(a)globalmegahost.com) for reporting the problem and to
Greg Darke (starstuff(a)optusnet.com.au) for sending a patch (I
modified the patch a bit to make it more efficient).
- Removed Identd scan support from NmapFE since Nmap no longer
supports it. Thanks to Jonathan Dieter (jdieter99(a)gmx.net) for the
patch.
- Fixed a bug that caused Nmap to crash if an nmap-service-probes file
was used which didn't contain the Exclude directive.
- Fixed a divide-by-zero crash when you specify rather bogus
command-line arguments (a TCP scan with zero tcp ports). Thanks to
Bart Dopheide (dopheide(a)fmf.nl) for identifying the problem and
sending a patch.
Changes:
3.93:
=====
o Modified Libpcap's configure.ac to compile with the
--fno-strict-aliasing option if gcc 4.X is used. This prevents when
said compiler is used. This was done for Nmap in 3.90, but is
apparently needed for pcap too. Thanks to Craig Humphrey
(Craig.Humphrey(a)chapmantripp.com) for the discovery.
o Patched libdnet to include sys/uio.h in src/tun-linux.c. This is
apparently necessary on some Glibc 2.1 systems. Thanks to Rob Foehl
(rwf(a)loonybin.net) for the patch.
o Fixed a crash which could occur when a ridiculously short
--host_timeout was specified on Windows (or on UNIX if --send_eth was
specified). Nmap now also prints a warning if you specify a
host_timeout of less than 1 second. Thanks to Ole Morten Grodaas
(grodaas(a)gmail.com) for discovering the problem.
3.91:
=====
o Fixed a crash on Windows when you -P0 scan an unused IP on a local
network (or a range that contains unused IPs). This could also
happen on UNIX if you specified the new --send_eth option. Thanks
to Jim Carras (JFCECL(a)engr.psu.edu) for reporting the problem.
o Fixed compilation on OpenBSD by applying a patch from Okan Demirmen
(okan(a)demirmen.com), who maintains Nmap in the OpenBSD Ports
collection.
o Updated nmap-mac-prefixes to include OUIs assigned by the IEEE since
April.
o Updated the included libpcre (used for version detection) from
version 4.3 to 6.3. A libpcre securty issue was fixed in 6.3, but
that issue never affected Nmap.
o Updated the included libpcap from 0.8.3 to 0.9.3. I also changed
the directory name in the Nmap tarball from libpcap-possiblymodified
to just libpcap. As usual, the modifications are described in the
NMAP_MODIFICATIONS in that directory.
3.90:
=====
o Added the ability for Nmap to send and properly route raw ethernet
packets cointaining IP datagrams rather than always sending the
packets via raw sockets. This is particularly useful for Windows,
since Microsoft has disabled raw socket support in XP for no good
reason. Nmap tries to choose the best method at runtime based on
platform, though you can override it with the new --send_eth and
--send_ip options.
o Added ARP scanning (-PR). Nmap can now send raw ethernet ARP requests to
determine whether hosts on a LAN are up, rather than relying on
higher-level IP packets (which can only be sent after a successful
ARP request and reply anyway). This is much faster and more
reliable (not subject to IP-level firewalling) than IP-based probes.
The downside is that it only works when the target machine is on the
same LAN as the scanning machine. It is now used automatically for
any hosts that are detected to be on a local ethernet network,
unless --send_ip was specified. Example usage: nmap -sP -PR
192.168.0.0/16 .
o Added the --spoof_mac option, which asks Nmap to use the given MAC
address for all of the raw ethernet frames it sends. The MAC given
can take several formats. If it is simply the string "0", Nmap
chooses a completely random MAC for the session. If the given
string is an even number of hex digits (with the pairs optionally
separated by a colon), Nmap will use those as the MAC. If less than
12 hex digits are provided, Nmap fills in the remainder of the 6
bytes with random values. If the argument isn't a 0 or hex string,
Nmap looks through the nmap-mac-prefixes to find a vendor name
containing the given string (it is case insensitive). If a match is
found, Nmap uses the vendor's OUI (3-byte prefix) and fills out the
remaining 3 bytes randomly. Valid --spoof_mac argument examples are
"Apple", "0", "01:02:03:04:05:06", "deadbeefcafe", "0020F2", and
"Cisco".
o Applied an enormous nmap-service-probes (version detection) update
from SoC student Doug Hoyte (doug(a)hcsw.org). Version 3.81 had
1064 match lines covering 195 service protocols. Now we have 2865
match lines covering 359 protocols! So the database size has nearly
tripled! This should make your -sV scans quicker and more
accurate. Thanks also go to the (literally) thousands of you who
submitted service fingerprints. Keep them coming!
o Applied a massive OS fingerprint update from Zhao Lei
(zhaolei(a)gmail.com). About 350 fingerprints were added, and many
more were updated. Notable additions include Mac OS X 10.4 (Tiger),
OpenBSD 3.7, FreeBSD 5.4, Windows Server 2003 SP1, Sony AIBO (along
with a new "robotic pet" device type category), the latest Linux 2.6
kernels Cisco routers with IOS 12.4, a ton of VoIP devices, Tru64
UNIX 5.1B, new Fortinet firewalls, AIX 5.3, NetBSD 2.0, Nokia IPSO
3.8.X, and Solaris 10. Of course there are also tons of new
broadband routers, printers, WAPs and pretty much any other device
you can coax an ethernet cable (or wireless card) into!
o Added 'leet ASCII art to the confugrator! ARTIST NOTE: If you think
the ASCII art sucks, feel free to send me alternatives. Note that
only people compiling the UNIX source code get this. (ASCII artist
unknown).
o Added OS, device type, and hostname detection using the service
detection framework. Many services print a hostname, which may be
different than DNS. The services often give more away as well. If
Nmap detects IIS, it reports an OS family of "Windows". If it sees
HP JetDirect telnetd, it reports a device type of "printer". Rather
than try to combine TCP/IP stack fingerprinting and service OS
fingerprinting, they are both printed. After all, they could
legitimately be different. An IP that gives a stack fingerprint
match of "Linksys WRT54G broadband router" and a service fingerprint
of Windows based on Kazaa running is likely a common NAT setup rather
than an Nmap mistake.
o Nmap on Windows now compiles/links with the new WinPcap 3.1
header/lib files. So please upgrade to 3.1 from
http://www.winpcap.org before installing this version of Nmap.
While older versions may still work, they aren't supported with Nmap.
o The official Nmap RPM files are now compiled statically for better
compatability with other systems. X86_64 (AMD Athlon64/Opteron)
binaries are now available in addition to the standard i386. NmapFE
RPMs are no longer distributed by Insecure.Org.
o Nmap distribution signing has changed. Release files are now signed
with a new Nmap Project GPG key (KeyID 6B9355D0). Fyodor has also
generated a new key for himself (KeyID 33599B5F). The Nmap key has
been signed by Fyodor's new key, which has been signed by Fyodor's
old key so that you know they are legit. The new keys are available
at http://www.insecure.org/nmap/data/nmap_gpgkeys.txt , as
docs/nmap_gpgkeys.txt in the Nmap source tarball, and on the public
keyserver network. Here are the fingerprints:
pub 1024D/33599B5F 2005-04-24
Key fingerprint = BB61 D057 C0D7 DCEF E730 996C 1AF6 EC50 3359 9B5F
uid Fyodor <fyodor@insecure.org>
sub 2048g/D3C2241C 2005-04-24
pub 1024D/6B9355D0 2005-04-24
Key fingerprint = 436D 66AB 9A79 8425 FDA0 E3F8 01AF 9F03 6B93 55D0
uid Nmap Project Signing Key (http://www.insecure.org/)
sub 2048g/A50A6A94 2005-04-24
o Fixed a crash problem related to non-portable varargs (vsnprintf)
usage. Reports of this crash came from Alan William Somers
(somers(a)its.caltech.edu) and Christophe (chris.branch(a)gmx.de).
This patch was prevalent on Linux boxes running an Opteron/Athlon64
CPU in 64-bit mode.
o Fixed crash when Nmap is compiled using gcc 4.X by adding the
--fno-strict-aliasing option when that compiler is detected. Thanks
to Greg Darke (starstuff(a)optusnet.com.au) for discovering that
this option fixes (hides) the problem and to Duilio J. Protti
(dprotti(a)flowgate.net) for writing the configure patch to detect
gcc 4 and add the option. A better fix is to identify and rewrite
lines that violate C99 alias rules, and we are looking into that.
o Added "rarity" feature to Nmap version detection. This causes
obscure probes to be skipped when they are unlikely to help. Each
probe now has a "rarity" value. Probes that detect dozens of
services such as GenericLines and GetRequest have rarity values of
1, while the WWWOFFLEctrlstat and mydoom probes have a rarity of 9.
When interrogating a port, Nmap always tries probes registered to
that port number. So even WWWOFFLEctrlstat will be tried against
port 8081 and mydoom will be tried against open ports between 3127
and 3198. If none of the registered ports find a match, Nmap tries
probes that have a rarity less than or equal to its current
intensity level. The intensity level defaults to 7 (so that most of
the probes are done). You can set the intensity level with the new
--version_intensity option. Alternatively, you can just use
--version_light or --version_all which set the intensity to 2 (only
try the most important probes and ones registered to the port
number) and 9 (try all probes), respectively. --version_light is
much faster than default version detection, but also a bit less
likely to find a match. This feature was designed and implemented
by Doug Hoyte (doug(a)hcsw.org).
o Added a "fallback" feature to the nmap-service-probes database.
This allows a probe to "inherit" match lines from other probes. It
is currently only used for the HTTPOptions, RTSPRequest, and
SSLSessionReq probes to inherit all of the match lines from
GetRequest. Some servers don't respond to the Nmap GetRequest (for
example because it doesn't include a Host: line) but they do respond
to some of those other 3 probes in ways that GetRequest match lines
are general enough to match. The fallback construct allows us to
benefit from these matches without repeating hundreds of signatures
in the file. This is another feature designed and implemented
by Doug Hoyte (doug(a)hcsw.org).
o Fixed crash with certain --excludefile or
--exclude arguments. Thanks to Kurt Grutzmacher
(grutz(a)jingojango.net) and pijn trein (ptrein(a)gmail.com) for
reporting the problem, and to Duilio J. Protti
(dprotti(a)flowgate.net) for debugging the issue and sending the
patch.
o Updated random scan (ip_is_reserved()) to reflect the latest IANA
assignments. This patch was sent in by Felix Groebert
(felix(a)groebert.org).
o Included new Russian man page translation by
locco_bozi(a)Safe-mail.net
o Applied pach from Steve Martin (smartin(a)stillsecure.com) which
standardizes many OS names and corrects typos in nmap-os-fingerprints.
o Fixed a crash found during certain UDP version scans. The crash was
discovered and reported by Ron (iago(a)valhallalegends.com) and fixed
by Doug Hoyte (doug(a)hcsw.com).
o Added --iflist argument which prints a list of system interfaces and
routes detected by Nmap.
o Fixed a protocol scan (-sO) problem which led to the error message:
"Error compiling our pcap filter: syntax error". Thanks to Michel
Arboi (michel(a)arboi.fr.eu.org) for reporting the problem.
o Fixed an Nmap version detection crash on Windows which led to the
error message "Unexpected error in NSE_TYPE_READ callback. Error
code: 10053 (Unknown error)". Thanks to Srivatsan
(srivatsanp(a)adventnet.com) for reporting the problem.
o Fixed some misspellings in docs/nmap.xml reported by Tom Sellers
(TSellers(a)trustmark.com).
o Applied some changes from Gisle Vanem (giva(a)bgnett.no) to make
Nmap compile with Cygwin.
o XML "osmatch" element now has a "line" attribute giving the
reference fingerprint line number in nmap-os-fingerprints.
o Added a distcc probes and a bunch of smtp matches from Dirk Mueller
(mueller(a)kde.org) to nmap-service-probes. Also added AFS version
probe and matches from Lionel Cons (lionel.cons(a)cern.ch). And
even more probes and matches from Martin Macok
(martin.macok(a)underground.cz)
o Fixed a problem where Nmap compilation would use header files from
the libpcap included with Nmap even when it was linking to a system
libpcap. Thanks to Solar Designer (solar(a)openwall.com) and Okan
Demirmen (okan(a)demirmen.com) for reporting the problem.
o Added configure option --with-libpcap=included to tell Nmap to use
the version of libpcap it ships with rather than any that may already be
installed on the system. You can still use --with-libpcap=[dir] to
specify that a system libpcap be installed rather than the shipped
one. By default, Nmap looks at both and decides which one is likely
to work best. If you are having problems on Solaris, try
--with-libpcap=included .
o Changed the --no-stylesheet option to --no_stylesheet to be
consistant with all of the other Nmap options. Though I'm starting to
like hyphens a bit better than underscores and may change all of the
options to use hyphens instad at some point.
o Added "Exclude" directive to nmap-service-probes grammar which
causes version detection to skip listed ports. This is helpful for
ports such as 9100. Some printers simply print any data sent to
that port, leading to pages of HTTP requests, SMB queries, X Windows
probes, etc. If you really want to scan all ports, specify
--allports. This patch came from Doug Hoyte (doug(a)hcsw.org).
o Added a stripped-down and heavily modified version of Dug Song's
libdnet networking library (v. 1.10). This helps with the new raw
ethernet features. My (extensive) changes are described in
libdnet-stripped/NMAP_MODIFICATIONS
o Removed WinIP library (and all Windows raw sockets code) since MS
has gone and broken raw sockets. Maybe packet receipt via raw
sockets will come back at some point. As part of this removal, the
Windows-specific --win_help, --win_list_interfaces, --win_norawsock,
--win_forcerawsock, --win_nopcap, --win_nt4route, --win_noiphlpapi,
and --win_trace options have been removed.
o Chagned the interesting ports array from a 65K-member array of
pointers into an STL list. This noticeable reduces memory usage in
some cases, and should also give a slight runtime performance
boost. This patch was written by Paul Tarjan (ptarjan(a)gmail.com).
o Removed the BSDFIX/BSDUFIX macros. The underlying bug in
FreeBSD/NetBSD is still there though. When an IP packet is sent
through a raw socket, these platforms require the total length and
fragmentation offset fields of an IP packet to be in host byte order
rather than network byte order, even though all the other fields
must be in NBO. I believe that OpenBSD fixed this a while back.
Other platforms, such as Linux, Solaris, Mac OS X, and Windows take
all of the fields in network byte order. While I removed the macro,
I still do the munging where required so that Nmap still works on
FreeBSD.
o Integrated many nmap-service-probes changes from Bo Jiang
(jiangbo(a)brandeis.edu)
o Added a bunch of RPC numbers from nmap-rpc maintainer Eilon Gishri
(eilon(a)aristo.tau.ac.il)
o Added some new RPC services to nmap-rpc thanks to a patch from
vlad902 (vlad902(a)gmail.com).
o Fixed a bug where Nmap would quit on Windows whenever it encountered
a raw scan of localhost (including the local ethernet interface
address), even when that was just one address out of a whole network
being scanned. Now Nmap just warns that it is skipping raw scans when
it encounters the local IP, but continues on to scan the rest of the
network. Raw scans do not currently work against local IP addresses
because Winpcap doesn't support reading/writing localhost interfaces
due to limitations of Windows.
o The OS fingerprint is now provided in XML output if debugging is
enabled (-d) or verbosity is at least 2 (-v -v). This patch was
sent by Okan Demirmen (okan(a)demirmen.com)
o Fixed the way tcp connect scan (-sT) respons to ICMP network
unreachable responses (patch by Richard Moore
(rich(a)westpoint.ltd.uk).
o Update random host scan (-iR) to support the latest IANA-allocated
ranges, thanks to patch by Chad Loder (cloder(a)loder.us).
o Updated GNU shtool (a helper program used during 'make install' to
version 2.0.2, which fixes a predictable temporary filename
weakness discovered by Eric Raymond.
o Removed addport element from XML DTD, since it is no longer used
(sugested by Lionel Cons (lionel.cons(a)cern.ch)
o Added new --privileged command-line option and NMAP_PRIVILEGED
environmental variable. Either of these tell Nmap to assume that
the user has full privileges to execute raw packet scans, OS
detection and the like. This can be useful when Linux kernel
capabilities or other systems are used that allow non-root users to
perform raw packet or ethernet frame manipulation. Without this
flag or variable set, Nmap bails on UNIX if geteuid() is
nonzero.
o Changed the RPM spec file so that if you define "static" to 1 (by
passing --define "static 1" to rpmbuild), static binaries are built.
o Fixed Nmap compilation on Solaris x86 thanks to a patch from Simon
Burr (simes(a)bpfh.net).
o ultra_scan() now sets pseudo-random ACK values (rather than 0) for
any TCP scans in which the initial probe packet has the ACK flag set.
This would be the ACK, Xmas, Maimon, and Window scans.
o Updated the Nmap version number, description, and similar fields
that MS Visual Studio places in the binary. This was done by editing
mswin32/nmap.rc as suggested by Chris Paget (chrisp@ngssoftware.com)
o Fixed Nmap compilation on DragonFly BSD (and perhaps some other
systems) by applying a short patch by Joerg Sonnenberger which omits
the declaration of errno if it is a #define.
o Fixed an integer overflow that prevented Nmap from scanning
2,147,483,648 hosts in one expression (e.g. 0.0.0.0/1). Problem
noted by Justin Cranford (jcranford(a)n-able.com). While /1 scans
are now possible, don't expect them to finish during your bathroom
break. No matter how constipated you are.
o Increased the buffer size allocated for fingerprints to prevent Nmap
from running out and quitting (error message: "Assertion
`servicefpalloc - servicefplen > 8' failed". Thanks to Mike Hatz
(mhatz(a)blackcat.com) for the report. [ Actually this was done in a
previous version, but I forgot which one ]
o Changed from CVS to Subversion source control system (which
rocks!). Neither repository is public (I'm paranoid because both CVS
and SVN have had remotely exploitable security holes), so the main
change users will see is that "Id" tags in file headers use the SVN
format for version numbering and such.
