# *
# * The Nmap Security Scanner is (C) 1996-2025 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,

# way if DISPLAY is set in one of the shell startup files like .profile.
# Those files only have an effect on the shell, not the graphical
# environment, so X11 starts up as expected, but in doing so it reads the
# startup scripts, and for some reason the first connection (the one that
# caused the launch) is rejected. But somehow subsequent connections work
# fine! So if the import fails, try one more time.
