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.
