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:
- Updated NmapFE to build with GTK2 rather than obsolete GTK1. Thanks
to Mike Basinger (dbasinge(a)speakeasy.net) and Meethune Bhowmick
(meethune(a)oss-institute.org) for developing the
patch. I made some changes as well to prevent compilation warnings.
The new NmapFE now seems to work, though I do get "Gtk-CRITICAL"
assertion error messages. If someone has time to look into this, that
would be appreciated.
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.
Changes:
- Nmap now prints a warning message on Windows if Winpcap is not found
(it then reverts to raw sockets mode if available, as usual).
- documentation fixes and updates.
Changes:
- Nmap now ships with and installs (in the same directory as other
data files such as nmap-os-fingerprints) an XSL stylesheet for
rendering the XML output as HTML. This stylesheet was written by
Benjamin Erb ( see http://www.benjamin-erb.de/nmap/ for examples).
It supports tables, version detection, color-coded port states, and
more. The XML output has been augmented to include an
xml-stylesheet directive pointing to nmap.xsl on the local
filesystem. You can point to a different XSL file by providing the
filename or URL to the new --stylesheet argument. Omit the
xml-stylesheet directive entirely by specifying --no-stylesheet.
The XML to HTML conversion can be done with an XSLT processor such
as Saxon, Sablot, or Xalan, but modern browsers can do this on the
fly -- simply load the XML output file in IE or Firefox. Some
features don't currently work with Firefox's on-the-fly rendering.
Perhaps some Mozilla wizard can fix that in either the XSL or the
browser itself. I hate having things work better in IE :). It is
often more convenient to have the stylesheet loaded from a URL
rather than the local filesystem, allowing the XML to be rendered on
any machine regardless of whether/where the XSL is installed. For
privacy reasons (avoid loading of an external URL when you view
results), Nmap uses the local filesystem by default. If you would
like the latest version of the stylesheet load from the web when
rendering, specify
--stylesheet http://www.insecure.org/nmap/data/nmap.xsl .
- Fixed fragmentation option (-f). One -f now sets sends fragments
with just 8 bytes after the IP header, while -ff sends 16 bytes to
reduce the number of fragments needed. You can specify your own
fragmentation offset (must be a multiple of 8) with the new --mtu
flag. Don't also specify -f if you use --mtu. Remember that some
systems (such as Linux with connection tracking) will defragment in
the kernel anyway -- so test first while sniffing with ethereal.
These changes are from a patch by Martin Macok
(martin.macok(a)underground.cz).
- Nmap now prints the number (and total bytes) of raw IP packets sent
and received when it completes, if verbose mode (-v) is enabled. The
report looks like:
Nmap finished: 256 IP addresses (3 hosts up) scanned in 30.632 seconds
Raw packets sent: 7727 (303KB) | Rcvd: 6944 (304KB)
- Fixed (I hope) an error which would cause the Windows version of
Nmap to abort under some circumstances with the error message
"Unexpected error in NSE_TYPE_READ callback. Error code: 10053
(Unknown error)". Problem reported by "Tony Golding"
(biz(a)tonygolding.com).
- Added new "closed|filtered" state. This is used for Idlescan, since
that scan method can't distinguish between those two states. Nmap
previously just used "closed", but this is more accurate.
- Null, FIN, Maimon, and Xmas scans now mark ports as "open|filtered"
instead of "open" when they fail to receive any response from the
target port. After all, it could just as easily be filtered as open.
This is the same change that was made to UDP scan in 3.70. Also as
with UDP scan, adding version detection (-sV) will change the state
from open|filtered to open if it confirms that they really are open.
- Fixed a bug in ACK scan that could cause Nmap to crash with the
message "Unexpected port state: 6" in some cases. Thanks to Glyn
Geoghegan (glyng(a)corsaire.com) for reporting the problem.
- Change IP protocol scan (-sO) so that a response from the target
host in any protocol at all will prove that protocol is open. As
before, no response means "open|filtered", an ICMP protocol
unreachable means "closed", and most other ICMP error messages mean
"filtered".
- Patched a Winpcap issue that prevented read timeouts from being
honored on Solaris (thus slowing down Nmap substantially). The
problem report and patch were sent in by Ben Harris
(bjh21(a)cam.ac.uk).
- Changed IP protocol scan (-sO) so that it sends valid ICMP, TCP, and
UDP headers when scanning protocols 1, 6, and 17, respectively. An
empty IP header is still sent for all other protocols. This should
prevent the error messages such as "sendto in send_ip_packet:
sendto(3, packet, 20, 0, 192.31.33.7, 16) => Operation not
permitted" that Linux (and perhaps other systems) would give when
they try to interpret the raw packet. This also makes it more
likely that these protocols will elicit a response, proving that the
protocol is "open".
- The windows build now uses header and static library files from
Winpcap 3.1Beta4. It also now prints out the DLL version you are
using when run with -d. I would recommend upgrading to 3.1Beta4 if
you have an older Winpcap installed.
- Added an NTP probe and matches to the version detection database
(nmap-service-probes) thanks to a submission from Martin
Macok (martin.macok@underground.cz).
- Applied several Nmap service detection database updates sent in by
Martin Macok (martin.macok(a)underground.cz).
Changes:
- The XML nmaprun element now has a startstr attribute which gives the
human readable calendar time format that a scan started. Similarly
the finished element now has a timestr attribute describing when the
scan finished. These are in addition to the existing nmaprun/start
and finished/time attributes that provided the start and finish time
in UNIX time_t notation. This should help in development of better
XSLT stylesheets for Nmap XML output.
- Added new "closed|filtered" state. This is used for Idlescan, since
that scan method can't distinguish between those two staes. Nmap
previously just used "closed", but this is more accurate.
- Rewrote the host IP (target specification) parser for easier
maintenance and to fix a bug found by Netris (netris(a)ok.kz)
- Fixed compilation on soem HP-UX 11 boxes thanks to a patch by Petter
Reinholdtsen (pere(a)hungry.com).
- Fixed a portability problem on some OpenBSD and FreeBSD machines
thanks to a patch by Okan Demirmen (okan(a)demirmen.com).
- Added an NTP probe and matches to the version detection database
(nmap-service-probes) thanks to a submission from Martin Macok
(martin.macok@underground.cz).
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
Significant changes:
- Rewrote core port scanning engine, which is now named ultra_scan().
Improved algorithms make this faster (often dramatically so) in
almost all cases. Not only is it superior against single hosts, but
ultra_scan() can scan many hosts (sometimes hundreds) in parallel.
This offers many efficiency/speed advantages. For example, hosts
often limit the ICMP port unreachable packets used by UDP scans to
1/second. That made those scans extraordinarily slow in previous
versions of Nmap. But if you are scanning 100 hosts at once,
suddenly you can receive 100 responses per second. Spreading the
scan amongst hosts is also gentler toward the target hosts. Nmap
can still scan many ports at the same time, as well. If you find
cases where ultra_scan is slower or less accurate, please send a
report (including exact command-lines, versions used, and output, if
possible) to Fyodor.
- Added --max_hostgroup option which specifies the maximum number of
hosts that Nmap is allowed to scan in parallel.
- Added --min_hostgroup option which specifies the minimum number of
hosts that Nmap should scan in parallel (there are some exceptions
where Nmap will still scan smaller groups -- see man page). Of
course, Nmap will try to choose efficient values even if you don't
specify hostgroup restrictions explicitly.
- Rewrote TCP SYN, ACK, Window, and Connect() scans to use
ultra_scan() framework, rather than the old pos_scan().
- Rewrote FIN, Xmas, NULL, Maimon, UDP, and IP Protocol scans to use
ultra_scan(), rather than the old super_scan().
- Overhauled UDP scan. Ports that don't respond are now classified as
"open|filtered" (open or filtered) rather than "open". The (somewhat
rare) ports that actually respond with a UDP packet to the empty
probe are considered open. If version detection is requested, it
will be performed on open|filtered ports. Any that respond to any of
the UDP probes will have their status changed to open. This avoids a
the false-positive problem where filtered UDP ports appear to be
open, leading to terrified newbies thinking their machine is
infected by back orifice.
- Nmap now estimates completion times for almost all port scan types
(any that use ultra_scan()) as well as service scan (version
detection). These are only shown in verbose mode (-v). On scans
that take more than a minute or two, you will see occasional updates
like:
SYN Stealth Scan Timing: About 30.01% done; ETC: 16:04 (0:01:09 remaining)
New updates are given if the estimates change significantly.
- Added --exclude option, which lets you specify a comma-separated
list of targets (hosts, ranges, netblocks) that should be excluded
from the scan. This is useful to keep from scannig yourself, your
ISP, particularly sensitive hosts, etc. The new --excludefile reads
the list (newline-delimited) from a given file. All the work was
done by Mark-David McLaughlin (mdmcl(a)cisco.com> and William McVey
( wam(a)cisco.com ), who sent me a well-designed and well-tested
patch.
- Nmap now has a "port scan ping" system. If it has received at least
one response from any port on the host, but has not received
responses lately (usually due to filtering), Nmap will "ping" that
known-good port occasionally to detect latency, packet drop rate,
etc.
- Service/version detection now handles multiple hosts at once for
more efficient and less-intrusive operation.
- Nmap now wishes itself a happy birthday when run on September 1 in
verbose mode! The first public release was on that date in 1997.
- The port randomizer now has a bias toward putting
commonly-accessible ports (80, 22, etc.) near the beginning of the
list. Getting a response early helps Nmap calculate response times and
detect packet loss, so the scan goes faster.
- Host timeout system (--host_timeout) overhauled to support host
parallelization. Hosts times are tracked separately, so a host that
finishes a SYN scan quickly is not penalized for an exceptionally
slow host being scanned at the same time.
- When Nmap has not received any responses from a host, it can now
use certain timing values from other hosts from the same scan
group. This way Nmap doesn't have to use absolute-worst-case
(300bps SLIP link to Uzbekistan) round trip timeouts and such.
- Enabled MAC address reporting when using the Windows version
of Nmap. Thanks to Andy Lutomirski (luto(a)stanford.edu) for
writing and sending the patch.
- Workaround crippled raw sockets on Microsoft Windows XP SP2 scans.
I applied a patch by Andy Lutomirski (luto(a)stanford.edu) which
causes Nmap to default to winpcap sends instead. The winpcap send
functionality was already there for versions of Windows such as NT and
Win98 that never supported Raw Sockets in the first place.
- Changed how Nmap sends Arp requests on Windows to use the iphlpapi
SendARP() function rather than creating it raw and reading the
response from the Windows ARP cache. This works around a
(reasonable) feature of Windows Firewall which ignored such
unsolicited responses. The firewall is turned on by default as of
Windows XP SP2. This change was implemented by Dana Epp
(dana(a)vulscan.com).
- Fixed some Windows portability issues discovered by Gisle Vanem
(giva(a)bgnett.no).
- Upgraded libpcap from version 0.7.2 to 0.8.3. This was an attempt
to fix an annoying bug, which I then found was actually in my code
rather than libpcap :).
- Removed Ident scan (-I). It was rarely useful, and the
implementation would have to be rewritten for the new ultra_scan()
system. If there is significant demand, perhaps I'll put it back in
sometime.
- Documented the --osscan_limit option, which saves time by skipping
OS detection if at least one open and one closed port are not found on
the remote hosts. OS detection is much less reliable against such
hosts anyway, and skipping it can save some time.
- Updated nmapfe.desktop file to provide better NmapFE desktop support
under Fedora Core and other systems. Thanks to Mephisto
(mephisto(a)mephisto.ma.cx) for sending the patch.
- Further nmapfe.desktop changes to better fit the freedesktop
standard. The patch came from Murphy (m3rf(a)swimmingnoodle.com).
- Fixed capitalization (with a perl script) of many over-capitalized
vendor names in nmap-mac-prefixes.
- Ensured that MAC address vendor names are always escaped in XML
output if they contain illegal characters (particularly '&'). Thanks
to Matthieu Verbert (mve(a)zurich.ibm.com) for the report and a patch.
- Changed xmloutputversion in XML output from 1.0 to 1.01 to note that
there was a slight change (which was actually the MAC stuff in 3.55).
Thanks to Lionel CONS (lionel.cons(a)cern.ch) for the suggestion.
- Many Windows portability fix and bug fixes, thanks to patch from
Gisle Vanem (giva(a)bgnett.no). With these changes, he was able to
compile Nmap on Windows using MingW + gcc 3.4 C++ rather than MS
Visual Studio.
- Removed (addport) tags from XML output. They used to provide open
ports as they were discovered, but don't work now that the port
scanners scan many hosts at once. They did not specify an IP
address. Of course the appropriate (port) tags are still printed
once scanning of a target is complete.
- Configure script now detects GNU/k*BSD systems (whatever those are),
thanks to patch from Robert Millan (rmh@debian.org)
- Fixed various crashes and assertion failures related to the new
ultra_scan() system, that were found by Arturo "Buanzo" Busleiman
(buanzo(a)buanzo.com.ar), Eric (catastrophe.net), and Bill Petersen
(bill.petersen(a)alcatel.com).
- Fixed some minor memory leaks relating to ping and list scanning as
well as the Nmap output table. These were found with valgrind (
http://valgrind.kde.org/ ).
- Provide limited --packet_trace support for TCP connect() (-sT)
scans.
- Fixed compilation on certain Solaris machines thanks to a patch by
Tom Duffy (tduffy(a)sun.com)
- Fixed some warnings that crop up when compiling nbase C files with a
C++ compiler. Thanks to Gisle Vanem (giva(a)bgnett.no) for sending
the patch.
- Tweaked the License blurb on source files and in the man page. It
clarifies some issues and includes a new GPL exception that
explicitly allows linking with the OpenSSL library. Some people
believe that the GPL and OpenSSL licenses are incompatable without
this special exception.
- Fixed some serious runtime portability issues on *BSD systems.
Thanks to Eric (catastrophe.net) for reporting the problem.
- Changed the argument parser to better detect bogus arguments to the
-iR option.
- Removed a spurious warning message relating to the Windows ARP cache
being empty. Patch by Gisle Vanem (giva(a)bgnett.no).
- Removed some C++-style line comments (//) from nbase, because some C
compilers (particularly on Solaris) barf on those. Problem reported
by Raju Alluri <Raju.Alluri(a)Sun.COM>
Changes:
========
- Added MAC address printing. If Nmap receives packet from a target
machine which is on an Ethernet segment directly connected to the
scanning machine, Nmap will print out the target MAC address. Nmap
also now contains a database (derived from the official IEEE
version) which it uses to determine the vendor name of the target
ethernet interface. The Windows version of Nmap does not yet have
this capability. If any Windows developer types are interesting in
adding it, you just need to implement IPisDirectlyConnected() in
tcpip.cc and then please send me the patch. Here are examples from
normal and XML output (angle brackets replaced with [] for HTML
changelog compatability):
MAC Address: 08:00:20:8F:6B:2F (SUN Microsystems)
[address addr="00:A0:CC:63:85:4B" vendor="Lite-on Communications"
addrtype="mac" /]
- Updated the XML DTD to support the newly printed MAC addresses.
Thanks to Thorsten Holz (thorsten.holz(a)mmweg.rwth-aachen.de) for
sending this patch.
- Added a bunch of new and fixed service fingerprints for version
detection. These are from Martin Macok
(martin.macok(a)underground.cz).
- Normalized many of the OS names in nmap-os-fingerprints (fixed
capitalization, typos, etc.). Thanks to Royce Williams
(royce(a)alaska.net) and Ping Huang (pshuang(a)alum.mit.edu) for
sending patches.
- Modified the mswine32/nmap_performance.reg Windows registry file to
use an older and more compatable version. It also now includes the
value "StrictTimeWaitSeqCheck"=dword:00000001 , as suggested by Jim
Harrison (jmharr(a)microsoft.com). Without that latter value, the
TcpTimedWaitDelay value apparently isn't checked. Windows users
should apply the new registry changes by clicking on the .reg file.
Or do it manually as described in README-WIN32. This file is also
now available in the data directory at
http://www.insecure.org/nmap/data/nmap_performance.reg
- Applied patch from Gisle Vanem (giva(a)bgnett.no) which allows the
Windows version of Nmap to work with WinPCAP 3.1BETA (and probably
future releases). The Winpcap folks apparently changed the encoding
of adaptor names in this release.
- Fixed a ping scanning bug that would cause this error message: "nmap:
targets.cc:196: int hostupdate (Target **, Target *, int, int, int,
timeout_info *, timeval *, timeval *, pingtune *, tcpqueryinfo *,
pingstyle): Assertion `pt->down_this_block > 0' failed." Thanks to
Beirne Konarski (beirne(a)neo.rr.com) for reporting the problem.
- If a user attempts -PO (the letter O), print an error suggesting
that they probably mean -P0 (Zero) to disable ping scanning.
- Applied a couple patches (with minor changes) from Oliver Eikemeier
(eikemeier(a)fillmore-labs.com) which fix an edge case relating to
decoy scanning IP ranges that must be sent through different
interfaces, and improves the Nmap response to certain error codes
returned by the FreeBSD firewall system. The patches are from
http://cvsweb.freebsd.org/ports/security/nmap/files/ .
- Many people have reported this error: "checking for type of 6th
argument to recvfrom()... configure: error: Cannot find type for 6th
argument to recvfrom()". In most cases, the cause was a missing or
broken C++ compiler. That should now be detected earlier with a
clearer message.
- Fixed the FTP bounce scan to better detect filered ports on the
target network.
- Fixed some minor bugs related to the new MAC address printing
feature.
- Fixed a problem with UDP-scanning port 0, which was reported by
Sebastian Wolfgarten (sebastian(a)wolfgarten.com).
- Applied patch from Ruediger Rissmann (RRI(a)zurich.ibm.com), which
helps Nmap understand an EACCESS error, which can happen at least
during IPv6 scans from certain platforms to some firewalled targets.
- Renamed ACK ping scan option from -PT to -PA in the documentation.
Nmap has accepted both names for years and will continue to do
so.
- Removed the notice that Nmap is reading target specifications from a
file or stdin when you specify the -iL option. It was sometimes
printed to stdout even when you wanted to redirect XML or grepable
output there, because it was printed during options processing before
output files were handled. This change was suggested by Anders Thulin
(ath(a)algonet.se).
- Added --source_port as a longer, but hopefully easier to remember,
alias for -g. In other words, it tries to use the constant source
port number you specify for probes. This can help against poorly
configured firewalls that trust source port 20, 53, and the like.
- Removed undocumented (and useless) -N option.
- Fixed a version detection crash reported in excellent detail by
Jedi/Sector One (j(a)pureftpd.org).
- Applied patch from Matt Selsky (selsky(a)columbia.edu) which helps
Nmap build with OpenSSL.
- Modified the configure/build system to fix library ordering problems
that prevented Nmap from building on certain platforms. Thanks to
Greg A. Woods (woods(a)weird.com) and Saravanan
(saravanan_kovai(a)HotPop.com) for the suggestions.
- Applied a patch to Makefile.in from Scott Mansfield
(thephantom(a)mac.com) which enables the use of a DESTDIR variable
to install the whole Nmap directory structure under a different root
directory. The configure --prefix option would do the same thing in
this case, but DESTDIR is apparently a standard that package
maintainers like Scott are used to. An example usage is
"make DESTDIR=/tmp/packageroot".
- Removed unnecessary banner printing in the non-root connect() ping
scan. Thanks to Tom Rune Flo (tom(a)x86.no) for the suggestion and
a patch.
- Updated the headers at the top of each source file (mostly to
advance the copyright year to 2004 and note that Nmap is a registered
trademark).
Sync with the latest nmap.
Changes (from nmap):
- Applied (with a few modifications) a large NmapFE patch from Peter
Marschall (peter(a)adpm.de). This patch adds a bunch more scan/ping
options and cleans up some redundant NmapFE code.
