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.com) 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/ * ***************************************************************************/ #ifndef COMMON_MODIFIED_H #define COMMON_MODIFIED_H 1 #include "nping.h" #include "common.h" /***************************************************************************** * STUFF FROM TargetGroup.h ****************************************************************************/ class TargetGroup { public: /* used by get_target_types */ enum _targets_types { TYPE_NONE, IPV4_NETMASK, IPV4_RANGES, IPV6_ADDRESS }; /* used as input to skip range */ enum _octet_nums { FIRST_OCTET, SECOND_OCTET, THIRD_OCTET }; TargetGroup(); /* Initializes (or reinitializes) the object with a new expression, such as 192.168.0.0/16 , 10.1.0-5.1-254 , or fe80::202:e3ff:fe14:1102 .
