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 (7 posts in 2015), moderated list for the most important 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.
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 Linux/BSD/Solaris compilation instructions and options are provided here. though this usually does the trick:
If you are compiling Nmap anyway, you might prefer to get the very latest code from our SVN source code repository rather than downloading a tarball here.
Microsoft Windows binaries
Please read the Windows section of the Install Guide for limitations and installation instructions for the Windows version of Nmap. You can choose from a self-installer (includes dependencies and also the Zenmap GUI) or the much smaller command-line zip file version. We support Nmap on Windows 7 and newer, as well as Windows Server 2008 and newer. We also maintain a guide for users who must run Nmap on earlier Windows releases..
Note: The version of Npcap included in our installers may not always be the latest version. If you experience problems or just want the latest and greatest version, download and install the latest Npcap release.
The Nmap executable Windows installer can handle Npcap 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:
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 Npcap and Microsoft Visual C++ 2013 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:
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. We have written a detailed guide to installing our RPM packages. though these simple commands usually do the trick: You can also download and install the RPMs yourself:
Mac OS X Binaries
Nmap binaries for Mac OS X (Intel x86) 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 computers running Mac OS X 10.8 and later. See the Mac OS X Nmap install page for more details. Users of PowerPC (PPC) Mac machines, which Apple ceased selling in 2006, should see this page instead for support information.
Other Operating Systems
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:
