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/ + * + ***************************************************************************/ + +#include "NpingTarget.h" + +#ifndef UTILS_NET_H +#define UTILS_NET_H 1 + +#ifndef NETINET_IN_SYSTM_H /* This guarding is needed for at least some versions of OpenBSD */ +#include <netinet/in_systm.h> /* defines n_long needed for netinet/ip.h */ +#define NETINET_IN_SYSTM_H +#endif +#ifndef NETINET_IP_H /* This guarding is needed for at least some versions of OpenBSD */ +#include <netinet/ip.h> +#define NETINET_IP_H +#endif + +int atoIP(const char *hostname, struct in_addr *dst); +int atoIP(const char *hostname, struct sockaddr_storage *ss, int family); +char *IPtoa(u32 i); +char *IPtoa(struct sockaddr_storage *ss); +char *IPtoa(struct in_addr addr); +char *IPtoa(struct in6_addr addr); +char *IPtoa(struct sockaddr_storage ss); +char *IPtoa(struct sockaddr_storage *ss, int family); +char *IPtoa(u8 *ipv6addr); +u16 sockaddr2port(struct sockaddr_storage *ss); +u16 sockaddr2port(struct sockaddr_storage ss); +u16 sockaddr2port(struct sockaddr_in *s4); +u16 sockaddr2port(struct sockaddr_in6 *s6); +int setsockaddrfamily(struct sockaddr_storage *ss, int family); +int setsockaddrany(struct sockaddr_storage *ss); +bool isICMPType(u8 type); +bool isICMPCode(u8 code); +bool isICMPCode(u8 code, u8 type); +int getPacketStrInfo(const char *proto, const u8 *packet, u32 len, u8 *dstbuff, u32 dstlen, struct sockaddr_storage *ss_src, struct sockaddr_storage *ss_dst); +int getPacketStrInfo(const char *proto, const u8 *packet, u32 len, u8 *dstbuff, u32 dstlen); +int getNetworkInterfaceName(u32 destination, char *dev); +int getNetworkInterfaceName(struct sockaddr_storage *dst, char *dev); +int nping_getpts_simple(const char *origexpr, u16 **list, int *count); +int resolveCached(char *host, struct sockaddr_storage *ss, size_t *sslen,int pf) ; +struct hostent *gethostbynameCached(char *host); +struct hostent *hostentcpy(struct hostent *src); +int hostentfree(struct hostent *src); +int parseMAC(const char *txt, u8 *targetbuff); +char *MACtoa(u8 *mac); +const char *arppackethdrinfo(const u8 *packet, u32 len, int detail ); +int arppackethdrinfo(const u8 *packet, u32 len, u8 *dstbuff, u32 dstlen); +int tcppackethdrinfo(const u8 *packet, size_t len, u8 *dstbuff, size_t dstlen, int detail, struct sockaddr_storage *src, struct sockaddr_storage *dst); +int udppackethdrinfo(const u8 *packet, size_t len, u8 *dstbuff, size_t dstlen, int detail, struct sockaddr_storage *src, struct sockaddr_storage *dst); +const char *getRandomTextPayload(); +int send_packet(NpingTarget *target, int rawfd, u8 *pkt, size_t pktLen); +int print_dnet_interface(const struct intf_entry *entry, void *arg) ; +int print_interfaces_dnet(); +struct sockaddr_storage *getSrcSockAddrFromIPPacket(u8 *pkt, size_t pktLen); +u8 *getUDPheaderLocation(u8 *pkt, size_t pktLen); +u8 *getTCPheaderLocation(u8 *pkt, size_t pktLen); +u8 getProtoFromIPPacket(u8 *pkt, size_t pktLen); +u16 *getSrcPortFromIPPacket(u8 *pkt, size_t pktLen); +u16 *getDstPortFromIPPacket(u8 *pkt, size_t pktLen); +u16 *getDstPortFromTCPHeader(u8 *pkt, size_t pktLen); +u16 *getDstPortFromUDPHeader(u8 *pkt, size_t pktLen); +int obtainRawSocket(); + +#define DEVNAMELEN 16 +#define PATH_PROC_IFINET6 "/proc/net/if_inet6" +typedef struct ipv6_interface{ + char devname[DEVNAMELEN]; /* Interface name */ + struct sockaddr_storage ss; /* Address as a sockaddr_storage var */ + u8 addr[16]; /* Address as a 128bit array */ + u16 netmask_bits; /* Prefix length */ + u8 dev_no; /* Netlink device number */ + u8 scope; /* Scope */ + u8 flags; /* Interface flags */ + u8 mac[6]; /* MAC addr.
