Nmap Port Scanner 5.50
Posted Jan 29, 2011
Authored by Fyodor | Site insecure.org

Nmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.

Changes: Nping packet probing and analysis tool has been added. Nmap Scripting Engine has been enhanced, and many new NSE scripts and libraries have been added (the new totals are 177 and 54, respectively). Many OS fingerprints and version detection signatures have been added, bringing the totals to 2,982 and 7,319, respectively. Zenmap GUI has been made faster when handling giant enterprise networks, and some new features have been added to it (script selection interface, printing support, and more).

Nmap is a utility for network exploration or security auditing. It supports ping scanning (determine which hosts are up), many port scanning techniques (determine what services the hosts are offering), and TCP/IP fingerprinting (remote host operating system identification). Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, sunRPC scanning, reverse-identd scanning, and more.

Changes: Added an extremely cool scan type -- IP Protocol scanning. Basically it sends a bunch of IP headers (no data) with different "protocol" fields to the host. The host then (usually) sends back a protocol unreachable for those that it does not support. By exclusion, nmap can make a list of those that are supported. Fixed some minor bugs in nmap and nmapfe, and added Russian and Lithuanian documentation.

In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). You just can't do all this with one scanning mode. And you don't want to have 10 different scanners around, all with different interfaces and capabilities. Thus I incorporated virtually e very scanning technique I know into nmap.

Changes: Interactive mode which allows you easily launch multiple scans (either synchronously or in the background), random scanning order (to evade IDS), a option to scan random IPs, and rpm fixes. RPM available here.

And you don't want to have 10 different scanners around, all with different interfaces and capabilities. Thus I incorporated virtually every scanning technique I know into nmap.

Changes: Added "firewall mode" timing optimizations which can decrease the ammount of time neccessary to SYN or connect scan some heavily filtered hosts. Changed "TCP Ping" to use a random ACK value rather than 0 (an IDS called Snort was using this to detect Nmap TCP Pings). Better Alpha/Linux support and FDDI support. Made OS detection smart enough to first check scan results for a known closed port instead of immediately resorting to a random one. This improves OS detection against some machines behind packet filters. (suggested by van Hauser). Applied a shortcut suggestion by Thomas Reinke which can lead to a tremendous speedup against some firewalled hosts. Added some ports commonly used for RPC to nmap-services. Added a number of new ports to nmap-services.

nmap v2.11. "nmap is a utility for port scanning large networks, although it works fine for single hosts.

And you don't want to have 10 different scanners around, all with different interfaces and capabilities. Thus I [Fyodor] incorporated virtually every scanning technique I [Fyodor] know into nmap. Specifically, nmap supports: Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses packet filters), UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings. Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, and output to machine parseable or human readable log files." -- Fyodor.

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, etc. and changed machine readable output to show service names now that nmap uses a specific services file rather than /etc/services; Fixed a link-list bug that could cause hangs in UDP,FIN,NULL, and XMAS scans, and fixed a pointer problem that could cause SIGSEGV; Several other little fixes to the installation script and minor scanner tweaks.

Nmap Scanning Utility 2.12
Posted Aug 17, 1999
Authored by Fyodor

nmap v2.12 is out! "nmap is a utility for port scanning large networks, although it works fine for single hosts. The guiding philosophy for the creation of nmap was TMTOWTDI (There's More Than One Way To Do It). This is the Perl slogan, but it is equally applicable to scanners. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). You just can't do all this with one scanning mode. And you don't want to have 10 different scanners around, all with different interfaces and capabilities. Thus I [Fyodor] incorporated virtually every scanning technique I [Fyodor] know into nmap. Specifically, nmap supports: Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses packet filters), UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings. Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, and output to machine parseable or human readable log files." -- Fyodor.

Changes: -sT now uses a different method to determine the results of a non-blocking connect() call (makes nmap more portable), got rid of the security warning message for people who are missing /dev/random and /dev/urandom due to complaints about the warning (note: This only silences the warnings -- it still uses relatively weak random number generation under Solaris and other systems that lack this functionality), eliminated pow() calls on Linux boxes to rectify a SIGSEGV condition, fixed an rpm problem.

nmap v2.05 - The Network Mapper - nmap is a utility for port scanning large networks, although it works fine for single hosts. General features include: Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses packet filters), UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings. Nmap also offers flexible target and port specification, decoy scanning, determination of TCP sequence predictability characteristics, and output to machine parseable or human readable log files. This latest release features: Over 25% more OS fingerprints, Nmap now comes with its own nmap-services, Increased the maximum number of OS guesses nmap will make, Random number generation now takes advantage of the /dev/urandom or /dev/random, Machine parseable logs are now more machine parseable, nmap-fingerprintinting-article, CHANGELOG file, updated docs, many bugfixes, code optimizations, much more. This is one of the most useful security tools ever created. Your security/network toolbag is incomplete without nmap! Check out the nmap directory for lots of nmap "add-ons" and accessories.
