/*************************************************************************** * ProbeMode.h -- Probe Mode is nping's default working mode. Basically, * * it involves sending the packets that the user requested at regular * * intervals and capturing responses from the wire. * * * ***********************IMPORTANT NMAP LICENSE TERMS************************ * * The Nmap Security Scanner is (C) 1996-2026 Nmap Software LLC ("The Nmap * Project"). 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 __PROBEMODE_H__ #define __PROBEMODE_H__ 1 #include "nping.h" #include "nsock.h" #include "NpingTarget.h" #include "utils_net.h" #include "utils.h" #define PKT_TYPE_TCP_CONNECT 1 #define PKT_TYPE_UDP_NORMAL 2 #define PKT_TYPE_TCP_RAW 3 #define PKT_TYPE_UDP_RAW 4 #define PKT_TYPE_ICMP_RAW 5 #define PKT_TYPE_ARP_RAW 6 /* The sendpkt structure is the data normalProbeMode() function passes to * the nsock event handler.
