Nmap is also a registered trademark of the Nmap Project. * * * * This program is distributed under the terms of the Nmap Public Source * * License (NPSL). The exact license text applying to a particular Nmap * * release or source code control revision is contained in the LICENSE * * file distributed with that version of Nmap or source code control * * revision. More Nmap copyright/legal information is available from * * https://nmap.org/book/man-legal.html, and further information on the * * NPSL license itself can be found at https://nmap.org/npsl. This header * * summarizes some key points from the Nmap license, but is no substitute * * for the actual license text. * * * * Nmap is generally free for end users to download and use themselves, * * including commercial use. It is available from https://nmap.org. * * * * The Nmap license generally prohibits companies from using and * * redistributing Nmap in commercial products, but we sell a special Nmap * * OEM Edition with a more permissive license and special features for * * this purpose. See https://nmap.org/oem * * * * If you have received a written Nmap license agreement or contract * * stating terms other than these (such as an Nmap OEM license), you may * * choose to use and redistribute Nmap under those terms instead. * * * * The official Nmap Windows builds include the Npcap software * * (https://npcap.org) for packet capture and transmission. It is under * * separate license terms which forbid redistribution without special * * permission. So the official Nmap Windows builds may not be * * redistributed without special permission (such as an Nmap OEM * * license). * * * * 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 submit your * * changes as a Github PR or by email to the dev@nmap.org mailing list * * for possible incorporation into the main distribution. Unless you * * specify otherwise, it is understood that you are offering us very * * broad rights to use your submissions as described in the Nmap Public * * Source License Contributor Agreement. This is important because we * * fund the project by selling licenses with various terms, and also * * because the inability to relicense code has caused devastating * * problems for other Free Software projects (such as KDE and NASM). * * * * The free version of Nmap 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. Warranties, * * indemnification and commercial support are all available through the * * Npcap OEM program--see https://nmap.org/oem. * * * ***************************************************************************/ /* $Id$ */ #ifndef NMAP_H #define NMAP_H /************************INCLUDES**********************************/ #ifdef HAVE_CONFIG_H #include "nmap_config.h" #else #ifdef WIN32 #include "nmap_winconfig.h" #endif /* WIN32 */ #endif /* HAVE_CONFIG_H */ #ifdef __amigaos__ #include "nmap_amigaos.h" #endif #if HAVE_UNISTD_H #include #endif #ifdef HAVE_BSTRING_H #include #endif /* Keep assert() defined for security reasons */ #undef NDEBUG #include /*#include *//* defines struct arphdr needed for if_ether.h */ // #if HAVE_NET_IF_H // #ifndef NET_IF_H /* why doesn't OpenBSD do this?! */ // #include // #define NET_IF_H // #endif // #endif // #if HAVE_NETINET_IF_ETHER_H // #ifndef NETINET_IF_ETHER_H // #include // #define NETINET_IF_ETHER_H // #endif /* NETINET_IF_ETHER_H */ // #endif /* HAVE_NETINET_IF_ETHER_H */ /******* DEFINES ************/ #ifdef NMAP_OEM #include "../nmap-build/nmap-oem.h" #endif #ifndef NMAP_NAME #define NMAP_NAME "Nmap" #endif #define NMAP_URL "https://nmap.org" #ifndef NMAP_VERSION /* Edit this definition only within the quotes, because it is read from this file by the makefiles. */ #define NMAP_VERSION "7.91" #define NMAP_NUM_VERSION "7.91.0.0" #endif #define NMAP_XMLOUTPUTVERSION "1.05" /* User configurable #defines: */ #define MAX_PROBE_PORTS 10 /* How many TCP probe ports are allowed ? */ /* Default number of ports in parallel.
