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 with the clarifications and exceptions described * # * below. 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@insecure.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 "derived 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: * # * o Integrates source code from Nmap * # * o Reads or includes Nmap copyrighted data files, such as * # * nmap-os-db or nmap-service-probes. * # * o Executes Nmap and parses the results (as opposed to typical shell or * # * execution-menu apps, which simply display raw Nmap output and so are * # * not derivative works.) * # * o Integrates/includes/aggregates Nmap into a proprietary executable * # * installer, such as those produced by InstallShield. * # * o Links to a library or executes a program that does any of the above * # * * # * The term "Nmap" should be taken to also include any portions or derived * # * works of Nmap, as well as other software we distribute under this * # * license such as Zenmap, Ncat, and Nping. This list is not exclusive, * # * but is meant to clarify our interpretation of derived works with some * # * common examples. Our interpretation applies only to Nmap--we don't * # * speak for other people's GPL works. * # * * # * If you have any questions about the GPL licensing restrictions on using * # * Nmap in non-GPL works, we would be 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@insecure.com for * # * further information. * # * * # * As a 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. You must obey the GNU GPL in all * # * respects for all of the code used other than OpenSSL. If you modify * # * this file, you may extend this exception to your version of the file, * # * but you are not obligated to do so. * # * * # * If you received these files with a written license agreement or * # * contract stating terms other than the terms above, then that * # * alternative license agreement takes precedence over these comments. * # * * # * 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 (none * # * have been found so far). * # * * # * 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. * # * * # * This program 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.
