* Added protocol scan (-sO), which determines what IP protocols
(TCP, IGMP, GRE, UDP, ICMP, etc) are supported by a given host.
This uses a clever technique designed and implemented by Gerhard
Rieger .
* Nmap now recognizes more than 700 operating system versions and
network devices (printers, webcams, routers, etc) thanks to
thousands of contributions from the user community! Many
operating systems were even recognized by Nmap prior to their
official release. Nmap3 also recognizes 2148 port assignments,
451 SunRPC services, and 144 IP protocols.
* Added Idlescan (-sI), which bounces the scan off a "zombie"
machine. This can be used to bypass certain (poorly configured)
firewalls and packet filters. In addition, this is the most
stealthy Nmap scan mode, as no packets are sent to the target
from your true IP address.
* The base Nmap package now builds and functions under Windows! It
is distributed in three forms: build-it-yourself source code, a
simple command-line package, or along with a nice GUI interface
(NmapWin) and a fancy installer. This is due to the hard work of
Ryan Permeh (from eEye), Andy Lutomirski, and Jens Vogt.
* Mac OS X is now supported, as well as the latest versions of
Linux, OpenBSD, Solaris, FreeBSD, and most other UNIX platforms.
Nmap has also been ported to several handheld devices -- see the
Related Projects page for further information.
* XML output (-oX) is now available for smooth interoperability
between Nmap and other tools.
* Added ICMP Timestamp and Netmask ping types (-PP and -PM). These
(especially timestamp) can be useful against some hosts that do
not respond to normal ping (-PI) packets. Nmap still allows TCP
"ping" as well.
* Nmap can now detect the uptime of many hosts when the OS Scan
option (-O) is used.
* Several new tests have been added to make OS detection more
accurate and provide more granular version information.
* Removed 128.210.*.* addresses from Nmap man page examples due to
complaints from Purdue security staff.
* The --data_length option was added, allowing for longer probe
packets. Among other uses, this defeats certain simplistic IDS
signatures.
* You can now specify distinct port UDP and TCP port numbers in a
single scan command using a command like 'nmap -sSU -p
U:53,111,137,T:21-25,80,139,515,6000,8080 target.com'. See the
man page for more usage info.
* Added mysterious, undocumented --scanflags and --fuzzy options.
* Nmap now provides IPID as well as TCP ISN sequence
predictability reports if you use -v and -O.
* SYN scan is now the default scan type for privileged (root)
users. This is usually offers greater performance while reducing
network traffic.
* Capitalized all references to God in error messages.
* Added List scan (-sL) which enumerates targets without scanning
them.
* The Nmap "random IP" scanning mode is now smart enough to skip
many unallocated netblocks.
* Tons of more minor features, bugfixes, and portability enhancements.
Changes from Nmap Changelog:
-- Fixed a commenting issue that could cause trouble for non-GNU compilers
(first found by Jan-Frode Myklebust (janfrode at parallab.uib.no))
-- A few new services to nmap-services
-- Fixed a "Status: Down" machine name output problem in machine
parseable logs found by Alek O. Komarnitsky ( alek (at) ast.lmco.com )
-- Took some wierd files out of the doc directory (cd, grep , vi, and
.swp)
-- Fixed some typos found by Thomas Klausner ( wiz (at)
danbala.ifoer.tuwien.ac.at )
Fixes PR 10054 by Reinoud Koornstra (reinoud@ibbnet.org).
Maintainer shared my opinion about architecture independent data files
belonging into share/ instead of lib/.
Other changes against 2.50: Target parsing bug fixed, new rpc number list.
Important changes since 2.12:
Remote OS identification by fingerprint, recognition of RPC programs
listening on the respective ports, scan timing controls, ACK/window
scanning, stop/restart scans, output readability improved, and lots of
bug fixes.
Changes: Changed the way tcp connect() scan determines the results of a
connect() call, got rid of the security warning message for people who are
missing /dev/random and /dev/urandom due to complaints about the
warning, eliminated pow() calls on Linux boxes, and fixed an RPM problem.
Changes: Many new fingerprints added, fixed IRIX problems which
prevented OS scanning from working on that platform, added support
for '-m -' to redirect machine readable logs to stdout for shell
pipelining, fixed a link-list bug that could cause hangs in
UDP,FIN,NULL, and XMAS scans, also fixed a pointer problem that
could cause SIGSEGV, fixed installation problem for people without
a /usr/local/man/man1 directory as well as several other little
fixes to the installation script and minor scanner tweaks.
