o [Zenmap] Added a new Scan Topology system. The idea is that if we
are going to call Nmap the "Network Mapper", it should at least be
able to draw you a map of the network! And that is what this new
system does. It was achieved by integrating the RadialNet Nmap
visualization tool (http://www.dca.ufrn.br/~joaomedeiros/radialnet),
into Zenmap. Joao Medeiros has been developing RadialNet for more
than a year. For details, complete with some of the most beautiful
Zenmap screen shots ever, visit

http://nmap.org/book/zenmap-topology.html. The integration work was
done by SoC student Vladimir Mitrovic and his mentor David Fifield.

o [Zenmap] Another exciting new Zenmap feature is Scan Aggregation.
This allows you to visualize and analyze the results of multiple
scans at once, as if they were from one Nmap execution. So you might
scan one network, analyze the results a bit, then scan some of the
machines more intensely or add a completely new subnet to the
scan. The new results are seamlessly added to the old, as described
at
http://nmap.org/book/zenmap-scanning.html#aggregation. [David,
Vladimir]

o Expanded nmap-services to include information on how frequently each
port number is found open. The results were generated by scanning
tens of millions of IPs on the Internet this Summer, and augmented
with internal network data contributed by some large
organizations. [Fyodor]

o Nmap now scans the most common 1,000 ports by default in either
protocol (UDP scan is still optional). This is a decrease from
1,715 TCP ports and 1,488 UDP ports in Nmap 4.68. So Nmap is faster
by default and, since the port selection is better thanks to the
port frequency data, it often finds more open ports as
well. [Fyodor]

o Nmap fast scan (-F) now scans the top 100 ports by default in either
protocol. This is a decrease from 1,276 (TCP) and 1,017 (UDP) in
Nmap 4.68. Port scanning time with -F is generally an order of
magnitude faster than before, making -F worthy of its "fast scan"
moniker. [Fyodor]

o The --top-ports option lets you specify the number of ports you wish
to scan in each protocol, and will pick the most popular ports for
you based on the new frequency data. For both TCP and UDP, the top
10 ports gets you roughly half of the open ports. The top 1,000
(out of 65,536 possible) finds roughly 93% of the open TCP ports and
more than 95% of the open UDP ports. [Fyodor, Doug Hoyte]

o David integrated all of your OS detection fingerprint and correction
submissions from March 11 until mid-July. In the process we reached
the 1500-signature milestone for the 2nd generation OS detection
system. We can now detect the newest iPhones, Linux 2.6.25, OS X
Darwin 9.2.2, Windows Vista SP1, and even the Nintendo Wii. Nmap now
has 1,503 signatures, vs. 1,320 in 4.68. Integration is now faster
and more pleasant thanks to the new OSassist application developed
by Nmap SoC student Michael Pattrick. See

http://seclists.org/nmap-dev/2008/q3/0089.html and

http://seclists.org/nmap-dev/2008/q3/0139.html for more details.

o Nmap now works with Windows 2000 again, after being broken by our
IPv6 support improvements in version 4.65. A couple new dependencies
are required to run on Win2K, as described at

http://nmap.org/book/inst-windows.html#inst-win2k .

o [Zenmap] Added a context-sensitive help system to the Profile
Editor. You can now mouse-over options to learn more about what
they are used for and their proper argument syntax. [Jurand Nogiec]

o When Nmap finds a probe during ping scan which elicits a response,
it now saves that information for the port scan and later phases.
It can then "ping" the host with that probe as necessary to collect
timing information even if the host is not responding to the normal
port scan packets. Previously, Nmap's port scan timing pings could
only use information gathered during that port scan itself. A
number of other "port scan ping" system improvements were made at
the same time to improve performance against firewalled hosts. For
full details, see
http://seclists.org/nmap-dev/2008/q3/0647.html
[David, Michael, Fyodor]

o --traceroute now uses the timing ping probe saved from host
discovery and port scanning instead of finding its own probe. The
timing ping probe is always the best probe Nmap knows about for
eliciting a response from a target. This will have the most effect
on traceroute after a ping scan, where traceroute would sometimes
pick an ineffective probe and traceroute would fail even though the
target was up. [David]

o Added dns-safe-recursion-port and dns-safe-recursion-txid
(non-default NSE scripts) which use the 3rd party dns-oarc.net
lookup to test the source port and transaction ID randomness of
discovered DNS servers (assuming they allow recursion at all).
These scripts, which test for the "Kaminsky" DNS bugs, were
contributed by Brandon Enright.

o Added whois.nse, which queries the Regional Internet Registries
(RIRs) to determine who the target IP addresses are assigned
to. [Jah]

o [Zenmap] Overhauled the default list of scan profiles based on
nmap-dev discussion. Users now have a much more diverse and useful
set of default profile options. And if they don't like any of those
canned scan commands, they can easily create their own in the
Profile Editor! [David]

o Fyodor made a number of performance tweaks, such as:
o increase host group sizes in many cases, so Nmap will now commonly
scan 64 hosts at a time rather than 30
o align host groups with common network boundaries, such as /24 or
/25
o Increase maximum per-target port-scan ping frequency to one every
1.25 seconds rather than every five. Port scan pings happen
against heavily firewalled hosts and the like when Nmap is not
receiving enough responses to normal scan to properly calculate
timing variables and detect packet drops.

o Added a new NSE binlib library, which offers bin.pack() and
bin.unpack() functions for dealing with storing values in and
extracting them from binary strings. For details, see

http://nmap.org/book/nse-library.html#nse-binlib . [Philip
Pickering]

o Added a new NSE DNS library. See this thread:

http://seclists.org/nmap-dev/2008/q3/0310.html [Philip Pickering]

o Added new NSE libraries for base64 encoding, SNMP, and POP3 mail
operations. They are described at

http://seclists.org/nmap-dev/2008/q3/0233.html . [Philip Pickering]

o Added NSE scripts popcapa (retrieves POP3 server capabilities) and
brutePOP3 (brute force POP3 authentication cracker) which make use
of the new POP3 library. [Philip Pickering]

o Added the SNMPcommunitybrute NSE script, which is a brute force
community string cracker. Also modified SNMPsysdescr to use the new
SNMP library. [Philip Pickering]

o Fixed the SMTPcommands script so that it can't return multiple
values (which was causing problems). Thanks to Jah for tracking down
the problem and sending a fix for SMTPcommands. Then Patrick fixed
NSE so it can handle misbehaving scripts like this without causing
mysterious side effects.

o Added a new NSE Unpwdb (username/password database) library for
easily obtaining usernames or passwords from a list. The functions
usernames() and passwords() return a closure which returns a new
list entry with every call, or nil when the list is exhausted. You
can specify your own username and/or password lists via the script
arguments userdb and passdb, respectively. [Kris]

o Nmap's Nsock-utilizing subsystems (DNS, NSE, version detection) have
been updated to support the -S and --ip-options flags. [Kris]

o A new --max-rate option was added, which complements --min-rate. It
allows you to specify the maximum byte rate that Nmap is allowed to
send packets. [David]

o Added --ip-options support for the connect() scan (-sT). [Kris]

o Nsock now supports binding to a local address and setting IPv4
options with nsi_set_localaddr() and nsi_set_ipoptions(),
respectively. [Kris]

o Added IPProto Ping (-PO) support to Traceroute, and fixed support for
IPProto Scan (-sO) and the ICMP Pings (-PE, -PP, -PM) in Traceroute
as well. These could cause Nmap to hang during Traceroute. [Kris]

o [Zenmap] Added a "Cancel" button for cancelling a scan in progress
without losing any Nmap output obtained so far. [Jurand Nogiec]

o Improve the netbios-smb-os-discovery NSE script to improve target
port selection and to also decode the system's timestamp from an SMB
response. [Ron at SkullSecurity]

o Nmap now avoids collapsing large numbers of ports in open|filtered
state (e.g. just printing that 500 ports are in that state rather
than listing them individually) if verbosity or debugging levels are
greater than two. See this thread:

http://seclists.org/nmap-dev/2008/q3/0312.html . [Fyodor]

o The NSE http library now supports chunked encoding. [Sven Klemm]

o The NSE datafiles library now has generic file parsing routines, and
the parsing of the standard nmap data files (e.g. nmap-services,
nmap-protocols, etc.) now uses those generic routines. NSE scripts
and libraries may find them useful for dealing with their own data
files, such as password lists. [Jah]

o Passed the big revision 10,000 milestone in the Nmap project SVN
server:
http://seclists.org/nmap-dev/2008/q3/0682.html

o Added some Windows and MinGW compatibility patches submitted by
Gisle Vanem.

o Improved nse_init so that compilation/runtime errors in NSE scripts
no longer cause the script engine to abort. [Patrick]

o Fix a cosmetic bug in --script-trace hex dump output which resulting
in bytes with the highest bit set being prefixed with ffffff. [Sven
Klemm]

o Removed the nselib-bin directory. The last remaining shared NSE
module, bit, has been made static by Patrick. Shared modules were
broken for static builds of Nmap, such as those in the RPMS. We also
had the compilation problems (particularly on OpenBSD) with shared
modules which lead us to make PCRE static a while back. [David]

o Updated rpcinfo NSE script to use the new pack/unpack (binlib)
functions, use the new tab library, include better documentation, and
fix some bugs. [Sven Klemm]

o Add useful details to the error message printed when an NSE script
fails to load (due to syntax error, etc.) [Patrick]

o Fix a bug in the NSE http library which would cause some scripts to
give the error: SCRIPT ENGINE: C:\Program
Files\Nmap\nselib/http.lua:77: attempt to call field 'parse' (a nil
value) [Jah]

o Fixed a Makefile problem (race condition) which could lead to build
failures when launching make in parallel mode (e.g. -j4). [Michal
Januszewski]

o Added new addrow() function to NSE tab library. It allows
developers to add a whole row at once rather than doing a separate
add() call for each column in a row. [Sven Klemm]

o Completion time estimates provided in verbose mode or when you hit a
key during scanning are now more accurate thanks to algorithm
improvements by David.

o Fixed a number of NSE scripts which used print_debug()
incorrectly. See

http://seclists.org/nmap-dev/2008/q3/0470.html. [Sven Klemm].

o [Zenmap] The Ports/Hosts view now provides full version detection
values rather than just a simple summary. [Jurand Nogiec]

o [Zenmap] When you edit the command-entry field, then change the
target selection, Nmap no longer blows away your edits in favor of
using your current profile. [Jurand Nogiec]

o Nsock now returns data from UDP packets individually, preserving the
packet boundary, rather than concatenating the data from multiple
packets into a single buffer. This fixes a problem related to our
reverse-DNS system, which can only handle one DNS packet at a time.
Thanks to Tim Adam of ManageSoft for debugging the problem and
sending the patch. Doug Hoyte helped with testing, and it was
applied by Fyodor.

o [Zenmap] Fixed a crash which would occur when you try to compare two
files, either of which has more than one extraports element. [David]

o Added the undocumented (except here) --nogcc option which disables
global/group congestion control algorithms and so each member of a
scan group of machines is treated separately. This is just an
experimental option for now. [Fyodor]

o [Zenmap] The Ports/Hosts display now has different colors for open
and closed ports. [Vladimir]

o Fixed Zenmap so that it displays all Nmap errors. Previously, only
stdout was redirected into the window, and not stderr. Now they are
both redirected. [Vladimir]

o NSE can now be used in combination with ping scan (e.g. "-sP
--script") so that you can execute host scripts without needing to
perform a port scan. [Kris]

o [NSE] Category names are now case insensitive. [Patrick]

o [NSE] Each thread for a script now gets its own action closure (and
upvalues). See:
http://seclists.org/nmap-dev/2008/q2/0549.html
[Patrick]

o [NSE] The script_scan_result structure has been changed to a class,
ScriptResult, which now holds a Script's output in an std::string.
This removes the need to use malloc and free to manage this memory.
A similar change was made to the run_record structure. [Patrick]

o [NSE] Fixed a socket exhaustion deadlock which could prevent a
script scan from ever finishing. Now, rather than limit the total
number of sockets which can be open, we limit the number of scripts
which can have sockets open at once. And once a script has one
socket opened, it is permitted to open as many more as it
needs. [Patrick]

o A hashing library (code from OpenSSL) was added to NSE. hashlib
contains md5 and sha1 routines. [Philip Pickering]

o Fixed host discovery probe matching when looking at the returned TCP
data in an ICMP error message. This could formerly lead to
incorrectly discarded responses and the debugging error message:
"Bogus trynum or sequence number in ICMP error message" [Kris]

o Fixed a segmentation fault in Nsock which occurred when calling
nsock_write() with a data length of -1 (which means the data is a
NUL-terminated string and Nsock should take the length itself) and
the Nsock trace level was at least 2. [Kris]

o The NSE Comm library now defaults to trying to read as many bytes as
are available rather than lines if neither the "bytes" nor "lines"
options are given. Thanks to Brandon for reporting a problem which
he noticed in the dns-test-open-recursion script. [Kris]

o Updated zoneTrans.nse to replace length bytes in returned domain
names to periods itself rather than relying on NSE's old behavior of
replacing non-printable characters with periods. Thanks to Rob
Nicholls for reporting the problem. [Kris]

o Some Zenmap crashes have been fixed: trying to "refresh" the output
of a scan loaded from a file, and trying to re-save a file loaded
from the command line in some circumstances. [David]

o [Zenmap] The file selector now remembers what directory it was last
looking at. [David]

o Added an extra layer of validity checking to received packets
(readip_pcap), just to be extra safe. See

http://seclists.org/nmap-dev/2008/q3/0644.html . [Kris]

o Zenmap defaults to showing files matching both *.xml and *.usr in
the file selector. Previously it only showed those matching *.usr.
The new combined format will be XML and .usr will be deprecated.
See
http://seclists.org/nmap-dev/2008/q3/0093.html .

o Nmap avoids printing the sending rate in bytes per second during a
TCP connect scan. Because the number of bytes per probe is not
known, it used to print current sending rates: 11248.85 packets / s,
0.00 bytes / s. Now it will print simply print rates like "11248.85
packets / s". [David]

o [Zenmap] Nmap's installation process now include .desktop files
which install menu items for launching Zenmap as a privileged or
non-privileged process on Linux. This will mainly effect people who
install nmap and Zenmap directly from the source code. [Michael]

o Improved performance of IP protocol scan by fixing a bug related to
timing calculations on ICMP probe responses. See r8754 svn log for
full details. [David]

o Nmap --reason output no longer falsely reports a localhost-response
during -PN scans. See

http://seclists.org/nmap-dev/2008/q3/0188.html. [Michael]

o [Zenmap] The higwidgets Python package has moved so it is now a
subpackage of zenmapGUI. This avoids naming conflicts with Umit,
which uses a slightly different version of higwidgets. [David]

o A bug that could cause some host discovery probes to be incorrectly
interpreted as drops was fixed. This occurred only when the IP
protocol ping (-PO) option was combined with other ping
types. [David]

o A new scanflags attribute has been added to XML output, which lists
all user specified --scanflags for the scan. nmap.dtd has been
modified to account for this. [Michael]

o The loading of the nmap-services file has been made much
faster--roughly 9 times faster in common cases. This is important
for the new (much larger) frequency augmented nmap-services
file. [David]

o Added a script (ASN.nse) which uses Team Cymru's DNS interface to
determine the routing AS numbers of scanned IP addresses. They even
set up a special domain just for Nmap queries. The script is still
experimental and non-default. [Jah, Michael]

o [Zenmap] Clicking "Cancel" in a file chooser in the diff interface
no longer causes a crash. [David]

o The shtool build helper script has been updated to version 2.0.8. An
older version of shutil caused installation to fail when the locale
was set to et_EE. Thanks to Michal Januszewski for the bug
report. [David]

o [Zenmap] Removed services.dmp and os_dmp.dmp and all the files that
referred to them. They are not needed with the new search
interface. Also removed an unused search progress bar. And some
broken fingerprint submission code. Yay for de-bloating! [David]

o [Zenmap] Added "%F" to the Exec link in the new Zenmap desktop
file. We expect (hope) that this will allow dragging and dropping
XML files onto the icon. [David]

o [Zenmap] The -o[XGASN] options can now be specified, just as you can
at the console. [Vladimir]

o [Zenmap] You can now shrink the scan window below its default
size thanks to NmapOutputViewer code enhancements. [David]

o [Zenmap] Removed optional use of the Psyco Python optimizer since
Zenmap is not the kind of CPU-bound application which benefits from
Psyco.

o [Zenmap] You can now select more than one host in the "Ports /
Hosts" view by control-clicking them in the column at left.

o [Zenmap] The profile editor now offers the --traceroute option.

o Zenmap now uses Unicode objects pervasively when dealing with Nmap
text output, though the only internationalized text Nmap currently
outputs is the user's time zone. [David]

o Unprintable characters in NSE script output (which really shouldn't
happen anyway) are now printed like \xHH, where HH is the
hexadecimal representation of the character. See

http://seclists.org/nmap-dev/2008/q3/0180.html . [Patrick]

o Nmap sometimes sent packets with incorrect IP checksums,
particularly when sending the UDP probes in OS detection. This has
been fixed. Thanks to Gisle Vanem for reporting and investigating the
bug. [David]

o Fixed the --without-liblua configure option so that it works
again. [David]

o In the interest of forward compatibility, the xmloutputversion
attribute in Nmap XML output is no longer constrained to be a
certain string ("1.02"). The xmloutputversion should be taken as
merely advisory by authors of parsers.

o Zenmap no longer leaves any temporary files lying around. [David]

o Nmap only prints an uptime guess in verbose mode now, because in
some situations it can be very inaccurate. See the discussion at

http://seclists.org/nmap-dev/2008/q3/0392.html. [David]

Nmap 4.76 [2008-9-12]

o There is a new "external" script category, for NSE scripts which
rely on a third-party network resource. Scripts that send data to
anywhere other than the target are placed in this category. Initial
members are ASN.nse, dns-safe-recursion-port.nse,
dns-safe-recursion-txid.nse, ripeQuery.nse, HTTP_open_proxy.nse, and
whois.nse [David]

o [Zenmap] A crash was fixed that affected Windows users with
non-ASCII characters in their user names. [David]
The error looked like this (with many variations):
UnicodeDecodeError: 'utf8' codec can't decode byte 0x9c in position 28:
unexpected code byte

o [Zenmap] Several corner-case crashes were fixed: [David]
File "radialnet\gui\NodeNotebook.pyo", line 429, in __create_widgets
KeyError: 'tcp'
File "radialnet\gui\RadialNet.pyo", line 1531, in __livens_up
AttributeError: 'NoneType' object has no attribute 'get_nodes'
File "zenmapGUI\MainWindow.pyo", line 308, in _create_ui_manager
GError: Odd character '\'
File "radialnet/gui/ControlWidget.py", line 104, in __create_widgets
AttributeError: 'module' object has no attribute 'STOCK_INFO'
File "radialnet\util\integration.pyo", line 385, in make_graph_from_hosts
KeyError: 'hops'

o [Zenmap] A crash was fixed that happened when opening the Hosts
Viewer with an empty list of hosts. [David]
The error message was
File "radialnet\gui\HostsViewer.pyo", line 167, in __cursor_callback
TypeError: GtkTreeModel.get_iter requires a tree path as its argument

o Improved rpcinfo.nse to correctly parse a wider variety of server
responses. [Sven Klemm]

o [Zenmap] Fixed a data encoding bug which could cause the crash
reporter itself to crash! [David]

o Nmap's Windows self-installer now correctly registers/deletes the
npf (Winpcap) service during install/uninstall. Also the silent
install mode was improved to avoid a case where the Winpcap
uninstaller was (non-silently) shown. [Rob Nicholls]

o Nmap's Windows self-installer now checks whether the MS Visual C++
runtime components have already been installed to avoid running it
again (which doesn't hurt anything, but slows down
installation). [Rob Nicholls]

o Fixed an assertion failure where raw TCP timing ping probes were
wrongly used during a TCP connect scan:
nmap: scan_engine.cc:2843: UltraProbe* sendIPScanProbe(UltraScanInfo*,
HostScanStats*, const probespec*, u8, u8):
Assertion `USI->scantype != CONNECT_SCAN' failed.
Thanks to LevelZero for the report. [David]

o Update the NSE bit library to replace deprecated use of
luaL_openlib() with luaL_register(). This fixes a build error which
occured on systems which have Lua libraries installed but
LUA_COMPAT_OPENLIB not defined [Sven]

o [Zenmap] The automatic crash reporter no longer requires an email
address. [David]

o [Zenmap] Highlighting of hostnames was improved to avoid wrongful
highlighting of certain elapsed times, byte counts, and other
non-hostname data. The blue highlight effects are now more subtle
(no longer bold, underlined, or italic) [David]

o [Zenmap] A warning that would occur when a host had the same service
running on more than one port was removed. Thanks to Toralf Förster
for the bug report. [David]
GtkWarning: gtk_box_pack_start: assertion `child->parent == NULL' failed
self.pack_start(widget, expand=False, fill=False)
