* scanengine.h -- Includes much of the "engine" functions for scanning, *
|
|
* such as pos_scan and super_scan. It also includes dependant functions *
|
|
* such as those for collectiong SYN/connect scan responses. *
|
|
* *
|
|
***********************IMPORTANT NMAP LICENSE TERMS************************
|
|
* *
|
|
* The Nmap Security Scanner is (C) 1996-2004 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. 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. 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 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. If you wish to specify *
|
|
* special license conditions of your contributions, just say so when you *
|
|
* send them. *
