Free nmap software for linux

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), version detection (determine what application/service is runing on a port), and TCP/IP fingerprinting (remote host OS or device identification).
Nmap project also offers flexible target and port specification, decoy/stealth scanning, SunRPC scanning, and more. Most Unix and Windows platforms are supported in both GUI and command line modes. Several popular handheld devices are also supported, including the Sharp Zaurus and the iPAQ.
Main features:
- Flexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.
- Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines.
- Portable: Most operating systems are supported, including Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.
- Easy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Both traditional command line and graphical (GUI) versions are available to suit your preference. Binaries are available for those who do not wish to compile Nmap from source.
- Free: The primary goals of the Nmap Project is to help make the Internet a little more secure and to provide administrators/auditors/hackers with an advanced tool for exploring their networks. Nmap is available for free download, and also comes with full source code that you may modify and redistribute under the terms of the GNU General Public License (GPL).
- Well Documented: Significant effort has been put into comprehensive and up-to-date man pages, whitepapers, and tutorials. Find them in multiple languages here.
- Supported: While Nmap comes with no warranty, you can write the author (fyodor@insecure.org) if you experience any problems. We also host several mailing lists you can join.
- Acclaimed: Nmap has won numerous awards, including "Information Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has been featured in hundreds of magazine articles and is even recommended by Microsoft. Visit the press page for further details.
- Popular: Thousands of people download Nmap every day, and it is included with many operating systems (Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD, etc). It is among the top ten (out of 30,000) programs at the Freshmeat.Net repository. This is important because it lends Nmap its vibrant development and user support communities.

Recent source releases and binary packages are described below. Older version (and sometimes newer test releases) are available from the dist directory (and really old ones are in dist-old) For the more security-paranoid (smart) users, GPG detached signatures and MD5/SHA-1 hashes for each release are available in the sigs directory (verification instructions). Before downloading, be sure to read the relevant sections for your platform from the Nmap Install Guide. The most important changes (features, bugfixes, etc) in each Nmap version are described in the Changelog. Using Nmap is found in the Reference Guide, and dont forget to read the other available documentation!

Nmap users are encouraged to subscribe to the Nmap-hackers mailing list. It is a low volume, moderated list for announcements about Nmap, Insecure.org, and related projects.

Nmap is distributed with source code under the terms of the GNU General Public License, with certain clarifications and exceptions noted in the copyright page. It includes a modified versions of the Libpcap packet capturing library, Libdnet low-level networking library, and the PCRE Perl-compatible regular expression library. It can optionally link to the OpenSSL Encryption Toolkit for SSL-enhanced service/version detection.

Nmap Parser is a module that implements a interface to the information contained in an nmap scan. It is implemented by parsing the xml scan data that is generated by nmap.
This will enable anyone who utilizes nmap to quickly create fast and robust security scripts that utilize the powerful port scanning abilities of nmap.
Enhancements:
- Parsing of distance information was added. Ignoring of taskend, taskbegin, and taskprogress information was added.
- Tests for nmap 4.20 were added.
- The license was changed to the MIT-style.
- The "always null" bug for the service->protocol call was fixed.

Nmap::Scanner is a Perl module to perform and manipulate nmap scans using perl.

SYNOPSIS

Perl extension for performing nmap (www.insecure.org/nmap) scans.

use Nmap::Scanner;

# Batch scan method

my $scanner = new Nmap::Scanner;
$scanner->tcp_syn_scan();
$scanner->add_scan_port(1-1024);
$scanner->add_scan_port(8080);
$scanner->guess_os();
$scanner->max_rtt_timeout(200);
$scanner->add_target(some.host.out.there.com.org);

# $results is an instance of Nmap::Scanner::Backend::Results
my $results = $scanner->scan();

# Print the results out as an well-formatted XML document
print $results->as_xml();

# Event scan method using *new* easier way to set scan options.

my $scanner = new Nmap::Scanner;
$scanner->register_scan_started_event(&scan_started);
$scanner->register_port_found_event(&port_found);
$scanner->scan(-sS -p 1-1024 -O --max-rtt-timeout 200 somehost.org.net.it);

sub scan_started {
my $self = shift;
my $host = shift;

my $hostname = $host->name();
my $addresses = join(,, map {$_->address()} $host->addresses());
my $status = $host->status();

print "$hostname ($addresses) is $statusn";
}

sub port_found {
my $self = shift;
my $host = shift;
my $port = shift;

my $name = $host->name();
my $addresses = join(,, map {$_->addr()} $host->addresses());

print "On host $name ($addresses), found ",
$port->state()," port ",
join(/,$port->protocol(),$port->portid()),"n";

}

This set of modules provides perl class wrappers for the network mapper (nmap) scanning tool (see http://www.insecure.org/nmap/). Using these modules, a developer, network administrator, or other techie can create perl routines or classes which can be used to automate and integrate nmap scans elegantly into new and existing perl scripts.

If you dont have nmap installed, you will need to download it BEFORE you can use these modules. Get it from http://www.insecure.org/nmap/. You will need nmap 3.10+ installed to use all the features of this module.

THC-Amap is a next-generation tool for assistingnetwork penetration testing. It performs fast and reliable application protocol detection, independant on the TCP/UDP port they are being bound to.
THC-Amap is a next-generation scanning tool for pentesters. It attempts to identify applications even if they are running on a different port than normal.
It also identifies non-ascii based applications. This is achieved by sending trigger packets, and looking up the responses in a list of response strings.
Currently there are two tools for this purpose: amap (you are looking at it), and nmap. Both have their strength and weaknesses, as they deploy different techniques. We recommend to use both tools for reliabe identification.
This tool is for legal purposes only!
If this tool is used as part of a commercial service (e.g. pentest), name, version and web address of this tool must be mentioned in the report.
If this tool is incorporated into a commercial tool (means: it costs money, has license costs or upgrade fees, etc.) or called by it, the name, version and web address of this tool must be mentioned in the report output of the tool. Addtionally, a commercial version, key file, etc. must be made available to the authors free of charge.
Enhancements:
- Included patch from ka0ttic AT gentoo.org for cleaner gcc compile
- Added SSL_Pending() to prevent rare locking on SSL ports, thanks to michel(at)arboi.fr.eu.org for reporting
- Added lots of fingerprints, most from Johnny Cyberpunk / THC -THANKS!
