/*************************************************************************** * portreasons.h -- Verbose packet-level information on port states * * * ***********************IMPORTANT NMAP LICENSE TERMS************************ * * * The Nmap Security Scanner is (C) 1996-2016 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. * * * * 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) * * * ***************************************************************************/ /* * Written by Eddie Bell 2007 * Modified by Colin Rice 2011 */ #ifndef REASON_H #define REASON_H #include "nbase.h" #ifdef WIN32 #include "winsock2.h" #else #include #endif #include #include class Target; class PortList; typedef unsigned short reason_t; /* Holds various string outputs of a reason * * Stored inside a map which maps enum_codes * * to reason_strings */ class reason_string { public: //Required for map reason_string(); reason_string(const char * singular, const char * plural); const char * singular; const char * plural; }; /* stored inside a Port Object and describes * why a port is in a specific state */ typedef struct port_reason { reason_t reason_id; union { struct sockaddr_in in; struct sockaddr_in6 in6; struct sockaddr sockaddr; } ip_addr; unsigned short ttl; int set_ip_addr(const struct sockaddr_storage *ss); } state_reason_t; /* used to calculate state reason summaries. * I.E 10 ports filter because of 10 no-responses */ typedef struct port_reason_summary { reason_t reason_id; unsigned int count; struct port_reason_summary *next; } state_reason_summary_t; enum reason_codes { ER_RESETPEER, ER_CONREFUSED, ER_CONACCEPT, ER_SYNACK, ER_SYN, ER_UDPRESPONSE, ER_PROTORESPONSE, ER_ACCES, ER_NETUNREACH, ER_HOSTUNREACH, ER_PROTOUNREACH, ER_PORTUNREACH, ER_ECHOREPLY, ER_DESTUNREACH, ER_SOURCEQUENCH, ER_NETPROHIBITED, ER_HOSTPROHIBITED, ER_ADMINPROHIBITED, ER_TIMEEXCEEDED, ER_TIMESTAMPREPLY, ER_ADDRESSMASKREPLY, ER_NOIPIDCHANGE, ER_IPIDCHANGE, ER_ARPRESPONSE, ER_NDRESPONSE, ER_TCPRESPONSE, ER_NORESPONSE, ER_INITACK, ER_ABORT, ER_LOCALHOST, ER_SCRIPT, ER_UNKNOWN, ER_USER, ER_NOROUTE, ER_BEYONDSCOPE, ER_REJECTROUTE, ER_PARAMPROBLEM, }; /* A map of reason_codes to plural and singular * * versions of the error string */ class reason_map_type{ private: std::map reason_map; public: reason_map_type(); std::map::iterator find(const reason_codes& x){ std::map::iterator itr = reason_map.find(x); if(itr == reason_map.end()) return reason_map.find(ER_UNKNOWN); return itr; }; }; /* Function to translate ICMP code and typ to reason code */ reason_codes icmp_to_reason(u8 proto, int icmp_type, int icmp_code); /* passed to the print_state_summary. * STATE_REASON_EMPTY will append to the current line, prefixed with " because of" * STATE_REASON_FULL will start a new line, prefixed with "Reason:" */ #define STATE_REASON_EMPTY 0 #define STATE_REASON_FULL 1 /* Passed to reason_str to determine if string should be in * plural of singular form */ #define SINGULAR 1 #define PLURAL 2 void state_reason_init(state_reason_t *reason); /* converts a reason_id to a string. number represents the * amount ports in a given state.
