Nmap and NmapFE (the graphical X Window front end) are available in
several versions and formats. 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 covered in the Reference Guide, and don't 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. You can join more than

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.
| Source Code Distribution (For compilation on Linux, Windows, Mac OS X, etc.) |
|---|
This is the traditional compile-it-yourself format. The Nmap
tarball compiles under UNIX (including Linux, Solaris,
Free/Net/OpenBSD, and Mac OS X) and Windows. It includes NmapFE, the UNIX X
Window frontend. Nmap is now offered in bzip2 format as well as traditional gzip.
Detailed compilation instructions and options are provided here, though this usually does the trick for Linux/BSD/Solaris systems:
bzip2 -cd nmap-4.21ALPHA4.tar.bz2 | tar xvf -
cd nmap-4.21ALPHA4
./configure
make
su root
make install
Instructions are also available for Windows source code compilation.
Latest development Nmap release tarball (recommended): nmap-4.21ALPHA4.tar.bz2 (or gzip compressed
Latest stable Nmap tarball: nmap-4.20.tar.bz2 (or gzip compressed)
Troubleshooting:
Mac OS X users: If you wish to compile from source (as opposed to
binaries later on this page), you need the Apple Developer Tools. See the Mac OS X Nmap Install page. If the normal "./configure" line above does
not work for you, try "./configure CPP=/usr/bin/cpp". If you think the "configure" script is looping, be sure
your computer's clock/date is set correctly and wait at least 10
minutes for completion before reporting it. If you still have trouble, let me
know.
Suse 9.0 users: See this
note for a workaround to a Suse kernel bug. You will need to
upgrade your kernel to 2.4.21-199 or higher, or compile Nmap using
special instructions in the email.
| Linux RPM Source and Binaries |
|---|
Many popular Linux distributions (Redhat, Mandrake, Suse, etc) use
the RPM package management system for
quick and easy binary package installation. These may not work with
Redhat 9 or earlier due to Libc incompatability issues. We have
written a detailed guide to
installing our RPM packages, though these simple commands (the
second is only necessary if you want the NmapFE GUI too) usually do
the trick:
rpm -vhU http://download.insecure.org/nmap/dist/nmap-4.21ALPHA4-1.i386.rpm
rpm -vhU http://download.insecure.org/nmap/dist/nmap-frontend-4.21ALPHA4-1.i386.rpm
You can also download and install the RPMs yourself:
Latest development release (recommended):
i386 Nmap RPM: nmap-4.21ALPHA4-1.i386.rpm
i386 Optional NmapFE GUI: nmap-frontend-4.21ALPHA4-1.i386.rpm
Source RPM (includes NmapFE): nmap-4.21ALPHA4-1.src.rpm
Latest stable release:
i386 Nmap RPM: nmap-4.20-1.i386.rpm
i386 Optional NmapFE GUI: nmap-frontend-4.20-1.i386.rpm
Source RPM (includes NmapFE): nmap-4.20-1.src.rpm
x86_64 (Opteron/Athlon 64 in 64-bit mode only) binaries are available from the dist directory.
| Windows (95/98/NT/ME/2K/XP) |
|---|
|
Windows is now well-supported by Nmap. Note that versions 3.90 and later require WinPcap 3.1 or later. Also
note that McAfee VirusScan improperly
labels Nmap as a "potentially unwanted program". We have pestered
McAfee for almost 2 years and they still haven't fixed the problem.
We recommend using other virus scanners instead, such as Trend
Micro's PC-cillin.
Microsoft intentionally broke
tools such as Nmap with their Service Pack 2 for Windows XP, though
recent versions of Nmap include a workaround that (mostly) resolves the
problem.

Please read the Windows section
of the Install Guide for limitations and installation instructions for
the Windows version of Nmap. Every stable Nmap release comes with
Windows command-line
binaries and associated files in a Zip archive. No graphical interface
is included, so you need to run nmap.exe from a DOS/command window.
See the screen shot above. Or you can download and install a superior
command shell such as those included with the free Cygwin system.
Nmap now has an executable Windows installer which can
handle WinPcap installation, registry performance tweaks, and
decompressing the executables and data files into your preferred
location. Skip all the complexity of the Windows zip files with a self-installer:
Latest development release self-installer (recommended): nmap-4.21ALPHA4-setup.exe
Latest stable release self-installer: nmap-4.20-setup.exe
We have written post-install usage
instructions). Please notify us
if you encounter any problems or have suggestions for the
installer.
For those who prefer the command-line zip files (Installation Instructions; Usage Instructions), they are still available:
Latest development command-line zipfile: nmap-4.21ALPHA4-win32.zip
Latest stable command-line zipfile: nmap-4.20-win32.zip
Nmapwin installer:
Nmapwin has been removed from this download page because it is
obsolete. Try the command-line version instead. By the way, eEye
NmapNT is even more obsolete, don't use that.
Troubleshooting
If you have trouble using the Windows version of Nmap (strange
error/compile/install/runtime messages) (and you have read the instructions, try the following:
- Does the error say "INSTMSIA.EXE not found"? Then download and
run it from here.
If the error asks for "InstMsiW.exe" instead, get it here.
- You might want to try installing
the Windows Network Monitor Driver Protocol.
- Check for error messages in the Windows event log (On at least WinXP, the
Event Viewer can be opened by running "eventvwr").
- Ensure that you have the latest version of WinPcap installed.
- Perhaps someone else has reported the problem. Try reading
recent Nmap-dev list archives.
If Nmap still doesn't work for you, please
mail nmap-dev@insecure.org with a thorough description of the problem
as well as the Windows flavor and Nmap version your are using.
Many other operating systems support Nmap so well that I have no need
to create and distribute binary packages myself. You can choose to
use the packages below, or compile the source
distribution, which is often newer. We have created installation pages for the following platforms:
Linux (all distributions)
Microsoft Windows
Mac OS X
FreeBSD, OpenBSD, and NetBSD
Sun Solaris
Amiga, HP-UX, and Other Platforms
