# ***********************IMPORTANT NMAP LICENSE TERMS************************
|
|
# *
|
|
# * The Nmap Security Scanner is (C) 1996-2024 Nmap Software LLC ("The Nmap
|
|
# * Project"). Nmap is also a registered trademark of the Nmap Project.
|
|
# *
|
|
# * 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
|
|
# * file distributed with that version of Nmap or source code control
|
|
# * revision. More Nmap copyright/legal information is available from
|
|
# * https://nmap.org/book/man-legal.html, and further information on the
|
|
# * 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.com) 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
|
|
# * useful, but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
# * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Warranties,
|
|
# * indemnification and commercial support are all available through the
