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 NPINGTARGET_H #define NPINGTARGET_H #include "nping.h" #include "common.h" #include "../libnetutil/netutil.h" #ifndef INET6_ADDRSTRLEN #define INET6_ADDRSTRLEN 46 #endif class NpingTarget { private: char devname[32]; /**< Net interface normal name */ char devfullname[32]; /**< Net interface full name */ devtype dev_type; /**< Type of network interface */ int directly_connected; /**< -1 = unset; 0 = no; 1 = yes */ int distance; /**< Distance to target in hops */ int addressfamily; /**< Address family: AF_INET or AF_INET6 */ char *nameIPBuf; /**< for the NameIP(void) function to return */ char *hostname; /**< Resolved host name */ int namedhost; /**< =1 is named host; =0 is an IP; =-1 unset */ char *targetname; /**< Name of the target host given on the * * command line if it is a named host */ struct sockaddr_storage targetsock; /**< Target address */ size_t targetsocklen; struct sockaddr_storage sourcesock; /**< Source address */ size_t sourcesocklen; struct sockaddr_storage spoofedsrcsock; /**< Spoofed Source address */ size_t spoofedsrcsocklen; bool spoofedsrc_set; struct sockaddr_storage nexthopsock; /**< Next Hop address */ size_t nexthopsocklen; char targetipstring[INET6_ADDRSTRLEN]; bool targetipstring_set; u8 MACaddress[6]; /**< Target MAC Address */ bool MACaddress_set; u8 SrcMACaddress[6]; /**< Source MAC Address */ bool SrcMACaddress_set; u8 NextHopMACaddress[6]; /**< Next Hop MAC Address */ bool NextHopMACaddress_set; /* This is for the ICMP identification field.
