- * 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

- *
- * Note that lines 2 & 3 are the same.  This is due to a buggy
- * kernel on the 2nd hop system -- lbl-csam.arpa -- that forwards
- * packets with a zero ttl.
- *
- * A more interesting example is:
- *
- *     [yak 72]% traceroute allspice.lcs.mit.edu.
- *     traceroute to allspice.lcs.mit.edu (18.26.0.115), 30 hops max

- *
- * (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

- *      4  ccngw-ner-cc.Berkeley.EDU (128.32.136.23)  39 ms  40 ms  19 ms
- *      5  ccn-nerif35.Berkeley.EDU (128.32.168.35)  39 ms  39 ms  39 ms

- *      9  * * *
- *     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...
