Nmap and Zenmap (the graphical 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 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, particularly the new book Nmap Network Scanning!
Nmap users are encouraged to subscribe to the Nmap-hackers
mailing list. It is a low volume (4 posts in 2009), moderated list
for the most important announcements about Nmap, Insecure.org, and
related projects. You can join more than 75,000 current subscribers

General Public License, with certain clarifications and exceptions
noted in the copyright page.
| Source Code Distribution (in case you wish to compile Nmap yourself) |
|---|
This is the traditional compile-it-yourself format. The Nmap
tarball compiles under Linux, Mac OS X, Windows, and many UNIX
platforms (Solaris, Free/Net/OpenBSD, etc.) It includes Zenmap, the
GUI 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-5.21.tar.bz2 | tar xvf -
cd nmap-5.21
./configure
make
su root
make install
Instructions are also available for Windows source code compilation.
Latest stable Nmap release tarball: nmap-5.21.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, please report it.
| Microsoft Windows binaries |
|---|
Nmap runs on all versions of Windows since NT, including 2K, XP, Vista,
Windows 7, and Server 2003/2008. Please read
the Windows section of the
Install Guide for limitations and installation instructions for the
Windows version of Nmap. In particular, read about
the special Windows 2000
(Win2K) dependencies if you use that platform. You can choose
from a self-installer (includes dependencies and also the Zenmap GUI)
or the much smaller command-line zip file version.
The Nmap executable Windows installer can handle WinPcap
installation, registry performance tweaks, and decompressing the
executables and data files into your preferred location. It also includes the Zenmap graphical frontend. Skip all the
complexity of the Windows zip files with a self-installer:
Latest stable release self-installer: nmap-5.21-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. The Zenmap graphical
interface is not included with these, so you need to run
nmap.exe from a DOS/command window. Or
you can download and install a superior command shell such as those
included with the free Cygwin
system. Also, you need to run the Winpcap and Microsoft Visual C++ Redistributable Package installers which are included in the zip file. The main advantage is that these zip files are a fraction of the size of the executable installer:
Latest stable command-line zipfile: nmap-5.21-win32.zip
Nmapwin installer:
Nmapwin has been removed from this download page because it is
obsolete. Try Zenmap (included in our installer) instead. By the way, eEye's
old NmapNT is even more obsolete, don't use that either.
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 send a detailed report the problem.
| 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 Zenmap GUI too) usually do
the trick:
rpm -vhU http://nmap.org/dist/nmap-5.21-1.i386.rpm
rpm -vhU http://nmap.org/dist/zenmap-5.21-1.noarch.rpm
You can also download and install the RPMs yourself:
Latest stable release:
i386 Nmap RPM: nmap-5.21-1.i386.rpm
i386 Ncat RPM: ncat-5.21-1.i386.rpm
x86-64 (64-bit Linux only!) Nmap RPM: nmap-5.21-1.x86_64.rpm
x86-64 (64-bit Linux only!) Ncat RPM: ncat-5.21-1.x86_64.rpm
Optional Zenmap GUI (all platforms): zenmap-5.21-1.noarch.rpm
Source RPM (includes Zenmap and Ncat): nmap-5.21-1.src.rpm
Nmap binaries for Mac OS X are distributed as a disk image file
containing an installer. The installer allows installing Nmap, Zenmap,
Ncat, and Ndiff. The programs have been tested on Intel and PowerPC
computers running Mac OS X 10.4 and later. See the
Mac OS X Nmap install
page for more details.
Latest stable release universal installer: nmap-5.21.dmg
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
