Nmap Scanning Utility 2.54 BETA 33
Posted Apr 27, 2002
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. Screenshot available here.

Changes: This version contains a huge OS fingerprint update - More than 100 added or changed. Applied fix for an important RPC scanning bug and a nasty OS fingerprinting bug. Does not show uptime when obviously spoofed (eg OpenBSD 3.0).

Changes: Bug fixes and portability improvements are included. Added a whole bunch of new OS fingerprints (and adjustments) ranging from big important ones (Linux 2.4.X, OpenBSD 2.9, FreeBSD 4.3, Cisco 12.2.1, MacOS X, etc) to some that are more obscure. Upgraded Libpcap to the latest version, and fixed some issues with the new Libpcap under Linux.

Nmap Scanning Utility 2.54 BETA 1
Posted May 29, 2000
Authored by Fyodor | Site insecure.org

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.

Nmap 2.52 - Added very simple man pages for xnmap/nmapfe (lack of man pages for these was noticed by LaMont Jones (lamont (at) hp.com), the Debian Nmap package maintainer, based on bug report by Adrian Bunk (bunk (at) fs.tum.de ). 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 ). Updated nmap-rpc with new entries found in the latest version of Eilon Gishri's rpc list.

Nmap Scanning Utility 2.51
Posted May 1, 2000
Authored by Fyodor | Site insecure.org

Nmap is a utility for network exploration or security auditing. Nmap 2.51 has been released, mostly to fix a target parsing bug found by Steve Horsburgh which could in some cases cause Nmap to crash with the error "Assertion 't->nleft > 1' failed". 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.
