/***************************************************************************
* rpc.h -- Functions related to the RPCGrind (-sR) facility of Nmap. *
* This includes reading the nmap-rpc services file and sending rpc *
* queries and interpreting responses. The actual scan engine used for *
* rpc grinding is pos_scan (which is not in this file) *
* *
***********************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. *
* *
* 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. See the GNU *
* General Public License for more details at *
* http://www.gnu.org/copyleft/gpl.html , or in the COPYING file included *
* with Nmap. *
