|
|
* This program is distributed under the terms of the Nmap Public Source *
|
|
* License (NPSL). The exact license text applying to a particular Nmap *
|
|
* release or source code control revision is contained in the LICENSE *

* NPSL license itself can be found at https://nmap.org/npsl. This header *
|
|
* summarizes some key points from the Nmap license, but is no substitute *
|
|
* for the actual license text. *
|
|
* *
|
|
* Nmap is generally free for end users to download and use themselves, *
|
|
* including commercial use. It is available from https://nmap.org. *
|
|
* *
|
|
* The Nmap license generally prohibits companies from using and *
|
|
* redistributing Nmap in commercial products, but we sell a special Nmap *
|
|
* OEM Edition with a more permissive license and special features for *
|
|
* this purpose. See https://nmap.org/oem *
|
|
* *
|
|
* If you have received a written Nmap license agreement or contract *
|
|
* stating terms other than these (such as an Nmap OEM license), you may *
|
|
* choose to use and redistribute Nmap under those terms instead. *
|
|
* *
|
|
* The official Nmap Windows builds include the Npcap software *
|
|
* (https://npcap.org) for packet capture and transmission. It is under *
|
|
* separate license terms which forbid redistribution without special *
|
|
* permission. So the official Nmap Windows builds may not be *
|
|
* redistributed without special permission (such as an Nmap OEM *
|
|
* license). *
|
|
* *
|
|
* Source is provided to this software because we believe users have a *
|
|
* right to know exactly what a program is going to do before they run it. *
|
|
* This also allows you to audit the software for security holes. *
|
|
* *
|
|
* Source code also allows you to port Nmap to new platforms, fix bugs, *
|
|
* and add new features. You are highly encouraged to submit your *
|
|
* changes as a Github PR or by email to the dev@nmap.org mailing list *
|
|
* for possible incorporation into the main distribution. Unless you *
|
|
* specify otherwise, it is understood that you are offering us very *
|
|
* broad rights to use your submissions as described in the Nmap Public *
|
|
* Source License Contributor Agreement. This is important because we *
|
|
* fund the project by selling licenses with various terms, and also *
|
|
* because the inability to relicense code has caused devastating *
|
|
* problems for other Free Software projects (such as KDE and NASM). *
|
|
* *
|
|
* The free version of Nmap is distributed in the hope that it will be *
|
