Downloading Nmap

Get the latest Nmap for your system:

Older versions (and sometimes newer test releases) are available from the Nmap release archive (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 official book Nmap Network Scanning !
