# ***********************IMPORTANT NMAP LICENSE TERMS************************
|
|
# * *
|
|
# * The Nmap Security Scanner is (C) 1996-2013 Insecure.Com LLC. Nmap is *
|
|
# * also a registered trademark of Insecure.Com LLC. This program is free *
|
|
# * software; you may redistribute and/or modify it under the terms of the *
|
|
# * GNU General Public License as published by the Free Software *
|
|
# * Foundation; Version 2 ("GPL"), BUT ONLY WITH ALL OF THE CLARIFICATIONS *
|
|
# * AND EXCEPTIONS DESCRIBED HEREIN. This guarantees your right to use, *
|
|
# * modify, and redistribute this software under certain conditions. If *
|
|
# * you wish to embed Nmap technology into proprietary software, we sell *
|
|
# * alternative licenses (contact sales@nmap.com). Dozens of software *
|
|
# * vendors already license Nmap technology such as host discovery, port *
|
|
# * scanning, OS detection, version detection, and the Nmap Scripting *
|
|
# * Engine. *
|
|
# * *
|
|
# * Note that the GPL places important restrictions on "derivative works", *
|
|
# * yet it does not provide a detailed definition of that term. To avoid *
|
|
# * misunderstandings, we interpret that term as broadly as copyright law *
|
|
# * allows. For example, we consider an application to constitute a *
|
|
# * derivative work for the purpose of this license if it does any of the *
|
|
# * following with any software or content covered by this license *
|
|
# * ("Covered Software"): *
|
|
# * *
|
|
# * o Integrates source code from Covered Software. *
|
|
# * *
|
|
# * o Reads or includes copyrighted data files, such as Nmap's nmap-os-db *
|
|
# * or nmap-service-probes. *
|
|
# * *
|
|
# * o Is designed specifically to execute Covered Software and parse the *
|
|
# * results (as opposed to typical shell or execution-menu apps, which will *
|
|
# * execute anything you tell them to). *
|
|
# * *
|
|
# * o Includes Covered Software in a proprietary executable installer. The *
|
|
# * installers produced by InstallShield are an example of this. Including *
|
|
# * Nmap with other software in compressed or archival form does not *
|
|
# * trigger this provision, provided appropriate open source decompression *
|
|
# * or de-archiving software is widely available for no charge. For the *
|
|
# * purposes of this license, an installer is considered to include Covered *
|
|
# * Software even if it actually retrieves a copy of Covered Software from *
|
|
# * another source during runtime (such as by downloading it from the *
|
|
# * Internet). *
|
|
# * *
|
|
# * o Links (statically or dynamically) to a library which does any of the *
|
|
# * above. *
|
|
# * *
|
|
# * o Executes a helper program, module, or script to do any of the above. *
|
|
# * *
|
|
# * This list is not exclusive, but is meant to clarify our interpretation *
|
|
# * of derived works with some common examples. Other people may interpret *
|
|
# * the plain GPL differently, so we consider this a special exception to *
|
|
# * the GPL that we apply to Covered Software. Works which meet any of *
|
|
# * these conditions must conform to all of the terms of this license, *
|
|
# * particularly including the GPL Section 3 requirements of providing *
|
|
# * source code and allowing free redistribution of the work as a whole. *
|
|
# * *
|
|
# * As another special exception to the GPL terms, Insecure.Com LLC grants *
|
|
# * permission to link the code of this program with any version of the *
|
|
# * OpenSSL library which is distributed under a license identical to that *
|
|
# * listed in the included docs/licenses/OpenSSL.txt file, and distribute *
|
|
# * linked combinations including the two. *
|
|
# * *
|
|
# * Any redistribution of Covered Software, including any derived works, *
|
|
# * must obey and carry forward all of the terms of this license, including *
|
|
# * obeying all GPL rules and restrictions. For example, source code of *
|
|
# * the whole work must be provided and free redistribution must be *
|
|
# * allowed. All GPL references to "this License", are to be treated as *
|
|
# * including the terms and conditions of this license text as well. *
|
|
# * *
|
|
# * Because this license imposes special exceptions to the GPL, Covered *
|
|
# * Work may not be combined (even as part of a larger work) with plain GPL *
|
|
# * software. The terms, conditions, and exceptions of this license must *
|
|
# * be included as well. This license is incompatible with some other open *
|
|
# * source licenses as well. In some cases we can relicense portions of *
|
|
# * Nmap or grant special permissions to use it in other open source *
|
|
# * software. Please contact fyodor@nmap.org with any such requests. *
|
|
# * Similarly, we don't incorporate incompatible open source software into *
|
|
# * Covered Software without special permission from the copyright holders. *
|
|
# * *
|
|
# * If you have any questions about the licensing restrictions on using *
|
|
# * Nmap in other works, are happy to help. As mentioned above, we also *
|
|
# * offer alternative license to integrate Nmap into proprietary *
|
|
# * applications and appliances. These contracts have been sold to dozens *
|
|
# * of software vendors, and generally include a perpetual license as well *
|
|
# * as providing for priority support and updates. They also fund the *
|
|
# * continued development of Nmap. Please email sales@nmap.com for further *
|
|
# * information. *
|
|
# * *
|
|
# * If you have received a written license agreement or contract for *
|
|
# * Covered Software stating terms other than these, you may choose to use *
|
|
# * and redistribute Covered Software under those terms instead of these. *
|
|
# * *
|
|
# * 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 send your changes *
|
|
# * to the dev@nmap.org mailing list for possible incorporation into the *
|
|
# * main distribution. By sending these changes to Fyodor or one of the *
|
|
# * Insecure.Org development mailing lists, or checking them into the Nmap *
|
|
# * source code repository, it is understood (unless you specify otherwise) *
|
|
# * that you are offering the Nmap Project (Insecure.Com LLC) the *
|
|
# * unlimited, non-exclusive right to reuse, modify, and relicense the *
|
|
# * code. Nmap will always be available Open Source, but this is important *
|
|
# * because the inability to relicense code has caused devastating problems *
|
|
# * for other Free Software projects (such as KDE and NASM). We also *
|
|
# * occasionally relicense the code to third parties as discussed above. *
|
|
# * If you wish to specify special license conditions of your *
|
|
# * contributions, just say so when you send them. *
|
