+ * traceroute host - trace the route ip packets follow going to "host".
+ *
+ * Attempt to trace the route an ip packet would follow to some
+ * internet host. 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. We don't want the destination
+ * host to process them so the destination port is set to an
+ * unlikely value (if some clod on the destination is using that
+ * value, it can be changed with the -p flag).
+ *
+ * A sample use might be:
+ *
+ * [yak 71]% traceroute nis.nsf.net.
+ * traceroute to nis.nsf.net (35.1.1.48), 30 hops max, 56 byte packet
+ * 1 helios.ee.lbl.gov (128.3.112.1) 19 ms 19 ms 0 ms

+ *
+ * (I start to see why I'm having so much trouble with mail to
+ * MIT.) Note that the gateways 12, 14, 15, 16 & 17 hops away
+ * either don't send ICMP "time exceeded" messages or send them
+ * with a ttl too small to reach us. 14 - 17 are running the
+ * MIT C Gateway code that doesn't send "time exceeded"s. God
+ * only knows what's going on with 12.
+ *
+ * The silent gateway 12 in the above may be the result of a bug in
+ * the 4.[23]BSD network code (and its derivatives): 4.x (x <= 3)
+ * sends an unreachable message using whatever ttl remains in the
+ * original datagram. Since, for gateways, the remaining ttl is
+ * zero, the icmp "time exceeded" is guaranteed to not make it back
+ * to us. The behavior of this bug is slightly more interesting
+ * when it appears on the destination system:
+ *
+ * 1 helios.ee.lbl.gov (128.3.112.1) 0 ms 0 ms 0 ms
+ * 2 lilac-dmc.Berkeley.EDU (128.32.216.1) 39 ms 19 ms 39 ms

+ * 10 * * *
+ * 11 * * *
+ * 12 * * *
+ * 13 rip.Berkeley.EDU (128.32.131.22) 59 ms ! 39 ms ! 39 ms !
+ *
+ * Notice that there are 12 "gateways" (13 is the final
+ * destination) and exactly the last half of them are "missing".
+ * What's really happening is that rip (a Sun-3 running Sun OS3.5)
+ * is using the ttl from our arriving datagram as the ttl in its
+ * icmp reply. 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...
