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 may be  * * willing to sell alternative licenses (contact sales@insecure.com).      * * Many security scanner vendors already license Nmap technology such as  * * our remote OS fingerprinting database and code, service/version         * * detection system, and port scanning code.                               * *                                                                         * * 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 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-fingerprints 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.  This list is not exclusive, but is just meant to        * * clarify our interpretation of derived works with some common examples.  * * These restrictions only apply when you actually redistribute Nmap.  For * * example, nothing stops you from writing and selling a proprietary       * * front-end to Nmap.  Just distribute it by itself, and point people to   * * http://www.insecure.org/nmap/ to download Nmap.                         * *                                                                         * * We don't consider these to be added restrictions on top of the GPL, but * * just a clarification of how we interpret "derived works" as it applies  * * to our GPL-licensed Nmap product.  This is similar to the way Linus     * * Torvalds has announced his interpretation of how "derived works"        * * applies to Linux kernel modules.  Our interpretation refers only to     * * Nmap - we don't speak for any other GPL products.                       * *                                                                         * * 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 many    * * security vendors, and generally include a perpetual license as well as  * * providing for priority support and updates as well as helping to fund   * * the continued development of Nmap technology.  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 Copying.OpenSSL 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.

You are highly encouraged to send your changes   * * to fyodor@insecure.org for possible incorporation into the main         * * distribution.  By sending these changes to Fyodor or one the            * * Insecure.Org development mailing lists, it is assumed that you are      * * offering Fyodor and 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.

By contrast, the GNU General Public License is intendedto guarantee your freedom to share and change free software--to make surethe software is free for all its users. This General Public License appliesto most of the Free Software Foundation's software and to any other programwhose authors commit to using it. (Some other Free Software Foundationsoftware is covered by the GNU Library General Public License instead.) Youcan apply it to your programs, too.When we speak of free software, we are referring to freedom, not price. OurGeneral Public Licenses are designed to make sure that you have the freedomto distribute copies of free software (and charge for this service if youwish), that you receive source code or can get it if you want it, that youcan change the software or use pieces of it in new free programs; and thatyou know you can do these things.To protect your rights, we need to make restrictions that forbid anyone todeny you these rights or to ask you to surrender the rights. Theserestrictions translate to certain responsibilities for you if you distributecopies of the software, or if you modify it.For example, if you distribute copies of such a program, whether gratis orfor a fee, you must give the recipients all the rights that you have. Youmust make sure that they, too, receive or can get the source code. And youmust show them these terms so they know their rights.We protect your rights with two steps: (1) copyright the software, and (2)offer you this license which gives you legal permission to copy, distributeand/or modify the software.Also, for each author's protection and ours, we want to make certain thateveryone understands that there is no warranty for this free software. Ifthe software is modified by someone else and passed on, we want itsrecipients to know that what they have is not the original, so that anyproblems introduced by others will not reflect on the original authors'reputations.Finally, any free program is threatened constantly by software patents. Wewish to avoid the danger that redistributors of a free program willindividually obtain patent licenses, in effect making the programproprietary. To prevent this, we have made it clear that any patent must belicensed for everyone's free use or not licensed at all.The precise terms and conditions for copying, distribution and modificationfollow.TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION0. This License applies to any program or other work which contains a noticeplaced by the copyright holder saying it may be distributed under the termsof this General Public License. The "Program", below, refers to any suchprogram or work, and a "work based on the Program" means either the Programor any derivative work under copyright law: that is to say, a workcontaining the Program or a portion of it, either verbatim or withmodifications and/or translated into another language. (Hereinafter,translation is included without limitation in the term "modification".) Eachlicensee is addressed as "you".Activities other than copying, distribution and modification are not coveredby this License; they are outside its scope. The act of running the Programis not restricted, and the output from the Program is covered only if itscontents constitute a work based on the Program (independent of having beenmade by running the Program). Whether that is true depends on what theProgram does.1. You may copy and distribute verbatim copies of the Program's source codeas you receive it, in any medium, provided that you conspicuously andappropriately publish on each copy an appropriate copyright notice anddisclaimer of warranty; keep intact all the notices that refer to thisLicense and to the absence of any warranty; and give any other recipients ofthe Program a copy of this License along with the Program.You may charge a fee for the physical act of transferring a copy, and youmay at your option offer warranty protection in exchange for a fee.2. You may modify your copy or copies of the Program or any portion of it,thus forming a work based on the Program, and copy and distribute suchmodifications or work under the terms of Section 1 above, provided that youalso meet all of these conditions:   * a) You must cause the modified files to carry prominent notices stating     that you changed the files and the date of any change.   * b) You must cause any work that you distribute or publish, that in     whole or in part contains or is derived from the Program or any part     thereof, to be licensed as a whole at no charge to all third parties     under the terms of this License.   * c) If the modified program normally reads commands interactively when     run, you must cause it, when started running for such interactive use     in the most ordinary way, to print or display an announcement including     an appropriate copyright notice and a notice that there is no warranty     (or else, saying that you provide a warranty) and that users may     redistribute the program under these conditions, and telling the user     how to view a copy of this License. (Exception: if the Program itself     is interactive but does not normally print such an announcement, your     work based on the Program is not required to print an announcement.)These requirements apply to the modified work as a whole.
