/***************************************************************************
|
|
* NpingTarget.h -- The NpingTarget class encapsulates much of the *
|
|
* information Nping has about a host. Things like next hop address or the *
|
|
* network interface that should be used to send probes to the target, are *
|
|
* stored in this class as they are determined. *
|
|
* *
|
|
***********************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 (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. See the Nmap *
|
|
* license file for more details (it's in a COPYING file included with *
|
|
* Nmap, and also available from https://svn.nmap.org/nmap/COPYING *
