We find out intermediate hops by launching probe - * packets with a small ttl (time to live) then listening for an - * icmp "time exceeded" reply from a gateway. We start our probes - * with a ttl of one and increase by one until we get an icmp "port - * unreachable" (which means we got to "host") or hit a max (which - * defaults to 30 hops & can be changed with the -m flag). Three - * probes (change with -q flag) are sent at each ttl setting and a - * line is printed showing the ttl, address of the gateway and - * round trip time of each probe. If the probe answers come from - * different gateways, the address of each responding system will - * be printed. If there is no response within a 5 sec. timeout - * interval (changed with the -w flag), a "*" is printed for that - * probe. - * - * Probe packets are UDP format.

So, the reply will time out on the return path - * (with no notice sent to anyone since icmp's aren't sent for - * icmp's) until we probe with a ttl that's at least twice the path - * length. I.e., rip is really only 7 hops away. A reply that - * returns with a ttl of 1 is a clue this problem exists. - * Traceroute prints a "!" after the time if the ttl is <= 1. - * Since vendors ship a lot of obsolete (DEC's Ultrix, Sun 3.x) or - * non-standard (HPUX) software, expect to see this problem - * frequently and/or take care picking the target host of your - * probes. - * - * Other possible annotations after the time are !H, !N, !P (got a host, - * network or protocol unreachable, respectively), !S or !F (source - * route failed or fragmentation needed -- neither of these should - * ever occur and the associated gateway is busted if you see one). If - * almost all the probes result in some kind of unreachable, traceroute - * will give up and exit. - * - * Notes - * ----- - * This program must be run by root or be setuid. (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 - */ - -#include -#include -#include -#include -#include -#include -#include - -#include - -#include -#include - -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include - -#define DUMMY_PORT 10010 - -#define MAXPACKET 65535 /* max ip packet size */ - -#ifndef HAVE_GETIPNODEBYNAME -#define getipnodebyname(x, y, z, u) gethostbyname2((x), (y)) -#define freehostent(x) -#endif - -/* - * Format of the data in a (udp) probe packet. - */ -struct packetdata { - u_char seq;
