(I suggest that - * you *don't* make it setuid -- casual use could result in a lot - * of unnecessary traffic on our poor, congested nets.) - * - * This program requires a kernel mod that does not appear in any - * system available from Berkeley: A raw ip socket using proto - * IPPROTO_RAW must interpret the data sent as an ip datagram (as - * opposed to data to be wrapped in a ip datagram). See the README - * file that came with the source to this program for a description - * of the mods I made to /sys/netinet/raw_ip.c. Your mileage may - * vary. But, again, ANY 4.x (x < 4) BSD KERNEL WILL HAVE TO BE - * MODIFIED TO RUN THIS PROGRAM. - * - * The udp port usage may appear bizarre (well, ok, it is bizarre). - * The problem is that an icmp message only contains 8 bytes of - * data from the original datagram. 8 bytes is the size of a udp - * header so, if we want to associate replies with the original - * datagram, the necessary information must be encoded into the - * udp header (the ip id could be used but there's no way to - * interlock with the kernel's assignment of ip id's and, anyway, - * it would have taken a lot more kernel hacking to allow this - * code to set the ip id). So, to allow two or more users to - * use traceroute simultaneously, we use this task's pid as the - * source port (the high bit is set to move the port number out - * of the "likely" range). To keep track of which probe is being - * replied to (so times and/or hop counts don't get confused by a - * reply that was delayed in transit), we increment the destination - * port number before each probe. - * - * Don't use this as a coding example. I was trying to find a - * routing problem and this code sort-of popped out after 48 hours - * without sleep. I was amazed it ever compiled, much less ran. - * - * I stole the idea for this program from Steve Deering. Since - * the first release, I've learned that had I attended the right - * IETF working group meetings, I also could have stolen it from Guy - * Almes or Matt Mathis. I don't know (or care) who came up with - * the idea first. I envy the originators' perspicacity and I'm - * glad they didn't keep the idea a secret. - * - * Tim Seaver, Ken Adelman and C. Philip Wood provided bug fixes and/or - * enhancements to the original distribution. - * - * I've hacked up a round-trip-route version of this that works by - * sending a loose-source-routed udp datagram through the destination - * back to yourself. Unfortunately, SO many gateways botch source - * routing, the thing is almost worthless. Maybe one day... - * - * -- Van Jacobson (van@helios.ee.lbl.gov) - * Tue Dec 20 03:50:13 PST 1988 - */ - -#define caddr_t void * - -#include -#include -#include -#include -#include - -#include - - -#include -#include -#include - -//void print(buf, cc, from); -char * inetname(struct in_addr); -double deltaT(struct timeval *, struct timeval *); -void usage(); -void send_probe(int, int); - -#define bzero( ptr, count ) memset( ptr, 0, count ) -#define bcopy(src,dest,len) memcpy(dest,src,len) - -// setlinebuf is equivalent to the setvbuf call below. -inline int setlinebuf(FILE *stream) -{ - return setvbuf( stream, (char*)0, _IONBF, 0 ); -} - -#ifndef __GNUC__ -#define EPOCHFILETIME (116444736000000000i64) -#else -#define EPOCHFILETIME (116444736000000000LL) -#endif - -struct timezone { - int tz_minuteswest; /* minutes W of Greenwich */ - int tz_dsttime; /* type of dst correction */ -}; - -int gettimeofday(struct timeval *tv, struct timezone *tz) -{ - FILETIME ft; - LARGE_INTEGER li; - __int64 t; - static int tzflag; - - if (tv) - { - GetSystemTimeAsFileTime(&ft); - //li.LowPart = ft.dwLowDateTime; - //li.HighPart = ft.dwHighDateTime; - t = li.QuadPart; /* In 100-nanosecond intervals */ - t -= EPOCHFILETIME; /* Offset to the Epoch time */ - t /= 10; /* In microseconds */ - tv->tv_sec = (long)(t / 1000000); - tv->tv_usec = (long)(t % 1000000); - } - - if (tz) - { - if (!tzflag) - { - _tzset(); - tzflag++; - } - tz->tz_minuteswest = _timezone / 60; - tz->tz_dsttime = _daylight; - } - - return 0; -} - - - -/* Set up endiannes macros for the ip and ip_icmp BSD headers */ -#ifndef BIG_ENDIAN -#define BIG_ENDIAN 4321 -#endif -#ifndef LITTLE_ENDIAN -#define LITTLE_ENDIAN 1234 -#endif -#ifndef BYTE_ORDER -#ifdef WORDS_BIGENDIAN -#define BYTE_ORDER BIG_ENDIAN -#else -#define BYTE_ORDER LITTLE_ENDIAN -#endif -#endif /* BYTE_ORDER */ - -#define u_int16_t WORD -#define u_int32_t DWORD - -/* These are BSD headers.
