Nmap 4.22SOC1 available
Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source (license).
- The UMIT graphical Nmap frontend is now included (as an ALPHA TEST
release) with the Nmap tarball distribution. It isn’t yet in the
RPMs or the Windows distributions. UMIT is written with Python/GTK
and has many huge advantages over NmapFE. It installs from the Nmap
source tarballs as part of the "make install" process unless you
specify —without-umit to configure. Please give UMIT a try (the
executable is named umit) and let us know the results! We hope to
include UMIT in the Windows Nmap distributions soon.
- The port selection mechanism was overhauled. Nmap now knows
(roughly) how common various services are, so you can specify
options such as —top-ports 50 to scan the 50 most popular ports.
You can also use the new —port-ratio option to scan ports above a
given popularity level. You can also now give the -p option service
names (such as ’http’) and wildcards (such as http* to include
services such as https and http-mgmt). There is also a bracket ()
operator for scanning all known ports within a given range. All
these changes, by Doug Hoyte, are described at
- Added more Nmap Scripting Engine scripts, bringing the total to 31.
The new ones are bruteTelnet (Eddie Bell), SMTPcommands (Jason
DePriest), iax2Detect (Jason), nbstat (Brandon Enright),
SNMPsysdescr (Thomas Buchanan), HTTPAuth (Thomas), finger (Eddie),
ircServerInfo (Doug Hoyte), and MSSQLm (Thomas Buchanan).
- Added the —reason option which explains WHY Nmap assigned a port
status. For example, a port could be listed as "filtered" because
no response was received, or because an ICMP network unreachable
message was received. [ Eddie ]
- Integrated all of your 2nd generation OS detection submissions,
increasing the database size by 68% since 4.21ALPHA4 to 699
fingerprints. The 2nd generation database is now nearly half (42%)
the size of the original. Please keep those submissions coming so
that we can do another integration round before the SoC program ends
on August 20! Thanks to David Fifield for doing most of the
