+
+v1.4 Wed Dec 13 22:50:35 PST 2000
+
+- Add an option to use icmp echo instead of udp datagrams.
+
+- Add HPUX and Linux support.
+
+- Handle hex argument values as suggested by John Hawkinson
+  (jhawk@mit.edu)
+
+- Added flags to set the first ttl and to set the don't fragment bit.
+
+- Add a local autoconf macro to check for routines in libraries; the
+  autoconf version is broken (it only puts the library name in the
+  cache variable name). Thanks to John Hawkinson.
+
+- Add a local autoconf macro to check for types; the autoconf version
+  is broken (it uses grep instead of actually compiling a code fragment).
+
+- Attempt to detect "egcs" versions of gcc.
+
+- Fix problems caused by savestr().
+
+- Detect when there are more interfaces than we can deal with. Thanks
+  to Guy Harris guy@netapp.com.
+
+- Accommodate changes made to FreeBSD 3.2-RELEASE network headers files.
+
+- The ip header offset needs to be byte swapped under Solaris on the
+  intel as well. Reported by John McDermott (jjm@jkintl.com) Also byte
+  ip length and offset for linux.
+
+- In wait_for_reply(), use passed socket instead of global one. Thanks
+  to Richard Kettlewell (richard.kettlewell@kewill.com)
+
+- Check for IFF_LOOPBACK as a define or an enum (concession to linux).
+  Reported by Robert Bihlmeyer (robbe@orcus.priv.at)
+
+- Increase size of SIOCGIFCONF buffer to accommodate systems with lots
+  of virtual interfaces. Ignore sun virtual interfaces. Suggested by
+  Ian Donaldson (iand@aone.com.au)
+
+- Always calculate icmp checksums when using -I. Reported by Soumen
+  (sbiswas@novell.com)
+
+- Documentation fix for description of -p. Thanks to Jeffrey C Honig
+  (jch@bsdi.com)
+
+- Enable ip checksums for Solaris 2.6 and higher (since they seem to
+  work correctly now).
+
+- Avoid problems when broken routers return 0.0.0.0 as their source
+  address. Thanks to John Hawkinson (jhawk@bbnplanet.com)
+
+- Canonicalize hostname if gethostname() doesn't return a domain.
+
+- Add -z flag (pause msecs) to allow optional pause between probes.
+  Suggested by Dave Morrison (drmorris@uplanet.com)
+
+- Fix max packet length test.
+
+- Use "/dev/null" instead of "." for file descriptor fodder.
+  Suggested by Tim Robbins (fyre@box3n.gumbynet.org)
+
+- Watch for a NULL argv[0]. Suggested by Tim Robbins.
+
+- Be careful with hostname legnths.
+
+- Print RFC1191 Path MTU Discovery value on "needfrag" unreachables.
+
+- Limit port size to 16 bits. Suggested by Tim Robbins.
+
+- Limit wait time to 24 hours.
+
+- Modified linux specific struct ipovly definition to avoid problems
+  with 64 bit systems. Problem reported by Uros Prestor
+  (uros@turbolinux.com)
+
+- Use kernel routing tables to determine correct source address.
+  Three styles are supported: bsd/socket, solaris/mib and linux.
+
+- Fix configure to recognize older versions of Solaris.
+
+v1.3.2 Thu Sep 26 18:06:16 PDT 1996
+
+- Rewrite source routing code to eliminate a number of problems on
+  systems using raw ip options. Also pad options with a noop so gateway
+  addresses are aligned.
+
+- Don't call inet_ntoa() twice in the same printf(). Thanks to NetBSD
+  via Bill Fenner (fenner@parc.xerox.com)
+
+- Decode "administratively prohibited filter" icmp code and print
+  numeric value for unknown codes. Thanks to Bill Fenner.
+
+v1.3.1 Wed Sep 18 21:08:16 PDT 1996
+
+- Some systems (e.g. AIX) need sys/select.h. Thanks to Brett Hogden
+  (hogden@rge.com)
+
+- Byte swap ip header length under Solaris. (This has no effect on the
+  sparc but is required on the i386.)
+
+- Made optional packet length control total size of packet.
+
+v1.3 Mon Sep 16 14:55:44 PDT 1996
+
+- Overrun buffer security fixes. Thanks to Bill Fenner
+  (fenner@parc.xerox.com)
+
+- Wait for response packet relative to start of probe. Thanks to Bill
+  Fenner.
+
+- Fix bug that prevented changing the packet size. Thanks to Gregory
+  Decker (gdecker@nate.dcrt.nih.gov)
+
+- Add support for RAW_OPTIONS (e.g. 4.4 BSD systems such as BSD/OS and
+  FreeBSD) thanks to Jeffrey C Honig (jch@bsdi.com)
+
+- Remove ip header byte swap fix from v1.2; most kernels swap the ip
+  header length in the kernel (and it causes OSF3 to crash).
+
+- Fix to not exit when the number of probes is set to 1 (i.e. "-q 1")
+
+- Improve autoconf configuration.
+
+v1.2 Tue Oct 17 23:50:05 PDT 1995
+
+- Convert to autoconf and ansify.
+
+- Byte swap ip header length for little endian machines. Fix thanks to
+  Y Badri (yb@greybox.demon.co.uk).
+
+v1.1 Thu Jun 15 02:32:55 PDT 1995
+
+- Check for too many arguments.
+
+- Recode to make timing of packet's round trip more obvious and to
+  tighten up code.
+
+- Ifdef IP_OPTIONS code.
+
+- Display time in microseconds.
+
+v1.0 Tue Feb 28 23:50:05 PDT 1989
+
+- Initial public release.

+
+Traceroute is known to build and run under SunOS 4.1.4 and Solaris 5.4.
+If you are running a really old kernel, see the instructions under the
+title "KERNEL MODIFICATIONS" further down.
+
+To build traceroute, first customize any paths in Makefile.in, then run
+"./configure" (a shell script). The configure script will determine
+your system attributes and generate an appropriate Makefile from
+Makefile.in. Next run "make". If everything goes well you can su to
+root and run "make install" and "make install-man". Note that traceroute
+must be installed setuid to root or run as root.
+
+If configure fails for some reason and decide to submit a bug report to
+traceroute@ee.lbl.gov, please include a copy of config.log.
+
+You will need an ANSI C compiler to build libpcap. The configure script
+will abort if your compiler is not ANSI compliant. If this happens, use
+the GNU C compiler, available via anonymous ftp:
+
+        ftp://prep.ai.mit.edu/pub/gnu/gcc-*.tar.gz
+
+If you get the error message:
+
+	traceroute: unknown protocol icmp
+
+it usually means you're missing the icmp line in /etc/protocols.
+
+If you are using Solaris 2.5.1 (and possibly higher), traceroute cannot
+calculate checksums; configure automatically changes the default to
+reflect this. The kernel updates the ip_id field with some unknown
+value and the ip_off field with the IP_DF bit. Also, if the the udp
+uh_sum field is non-zero, it gets updated with the value of the uh_ulen
+field... This means that the icmp echo option (-I flag) is not as
+useful.
+
+KERNEL MODIFICATIONS
+--------------------
+If yor have a really old system, it may be necessary to modify your
+kernel before traceroute will work. If you want to hack on your kernel,
+a modified version of the routine rip_output (normally found in the
+file /sys/netinet/raw_ip.c) can be found in rip_output.c. This code may
+or may not resemble the code in your kernel. It may offer you a place
+to start but we make no promises. If you do hack your kernel, remember
+to test everything that uses raw ip sockets (e.g., ping and
+egpup/gated) & make sure they still work. We wish you the best of luck
+and you're on your own.
+
+Some older kernels forward icmp packets that have a ttl of zero. If
+your system has this bug, you might want to fix it while you're in the
+kernel.  (This bug appears in all releases of BSD up to but not
+including 4.3tahoe. If your version of netinet/ip_icmp.c is any earlier
+than 7.3 (April, '87), it has the bug.)  The fix is just to add the
+line:
+
+	ip->ip_ttl = MAXTTL;
+
+after the line:
+
+	ip->ip_src = t;
+
+(or anywhere before the call to icmp_send) in routine icmp_reflect.
+
+If you're running this on a pre-4.3bsd system (e.g., SunOS 3) that
+strips ip headers from icmp messages, add -DARCHAIC to CFLAGS in the
+Makefile.  Also note that rip_output contains a conditional for a
+4.2/4.3 change in the location of a raw socket's protocol number.  I've
+checked this under 4.3 & SunOS 3 but you should double-check your
+system to make sure the appropriate branch of the #if is taken (check
+the line that assigned to ip->ip_p in your system's original
+rip_output).

+TRACEROUTE 1.4
+Lawrence Berkeley National Laboratory
+Network Research Group
+traceroute@ee.lbl.gov
+ftp://ftp.ee.lbl.gov/traceroute.tar.gz
+
+Traceroute is a system administrators utility to trace the route
+ip packets from the current system take in getting to some
+destination system.  See the comments at the front of the
+program for a description of its use.
+
+This program uses raw ip sockets and must be run as root (or installed
+setuid to root).
+
+A couple of awk programs to massage the traceroute output are
+included.  "mean.awk" and "median.awk" compute the mean and median time
+to each hop, respectively.  I've found that something like
+
+    traceroute -q 7 foo.somewhere >t
+    awk -f median.awk t | xgraph
+
+can give you a quick picture of the bad spots on a long path (median is
+usually a better noise filter than mean).
+
+Problems, bugs, questions, desirable enhancements, source code
+contributions, etc., should be sent to the email address
+"traceroute@ee.lbl.gov".

+dnl This test is for network applications that need socket() and
+dnl gethostbyname() -ish functions.  Under Solaris, those applications
+dnl need to link with "-lsocket -lnsl".  Under IRIX, they need to link
+dnl with "-lnsl" but should *not* link with "-lsocket" because
+dnl libsocket.a breaks a number of things (for instance:
+dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
+dnl versions of IRIX).
+dnl
+dnl Unfortunately, many application developers are not aware of this,
+dnl and mistakenly write tests that cause -lsocket to be used under
+dnl IRIX.  It is also easy to write tests that cause -lnsl to be used
+dnl under operating systems where neither are necessary (or useful),
+dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
+dnl
+dnl This test exists so that every application developer does not test
+dnl this in a different, and subtly broken fashion.
+
+dnl It has been argued that this test should be broken up into two
+dnl seperate tests, one for the resolver libraries, and one for the
+dnl libraries necessary for using Sockets API. Unfortunately, the two
+dnl are carefully intertwined and allowing the autoconf user to use
+dnl them independantly potentially results in unfortunate ordering
+dnl dependancies -- as such, such component macros would have to
+dnl carefully use indirection and be aware if the other components were
+dnl executed. Since other autoconf macros do not go to this trouble,
+dnl and almost no applications use sockets without the resolver, this
+dnl complexity has not been implemented.
+dnl
+dnl The check for libresolv is in case you are attempting to link
+dnl statically and happen to have a libresolv.a lying around (and no
+dnl libnsl.a).

+.SH DESCRIPTION
+The Internet is a large and complex aggregation of
+network hardware, connected together by gateways.
+Tracking the route one's packets follow (or finding the miscreant
+gateway that's discarding your packets) can be difficult.
+.I Traceroute
+utilizes the IP protocol `time to live' field and attempts to elicit an
+ICMP TIME_EXCEEDED response from each gateway along the path to some
+host.
+.PP
+The only mandatory parameter is the destination host name or IP number.
+The default probe datagram length is 40 bytes, but this may be increased
+by specifying a packet length (in bytes) after the destination host
+name.
+.PP
+Other options are:
+.TP
+.B \-f
+Set the initial time-to-live used in the first outgoing probe packet.
+.TP
+.B \-F
+Set the "don't fragment" bit.
+.TP
+.B \-d
+Enable socket level debugging.
+.TP
+.B \-g
+Specify a loose source route gateway (8 maximum).
+.TP
+.B \-i
+Specify a network interface to obtain the source IP address for
+outgoing probe packets. This is normally only useful on a multi-homed
+host. (See the
+.B \-s
+flag for another way to do this.)
+.TP
+.B \-I
+Use ICMP ECHO instead of UDP datagrams.
+.TP
+.B \-m
+Set the max time-to-live (max number of hops) used in outgoing probe
+packets.  The default is 30 hops (the same default used for TCP
+connections).
+.TP
+.B \-n
+Print hop addresses numerically rather than symbolically and numerically
+(saves a nameserver address-to-name lookup for each gateway found on the
+path).
+.TP
+.B \-p
+Set the base UDP port number used in probes (default is 33434).
+Traceroute hopes that nothing is listening on UDP ports
+.I base
+to
+.I base + nhops - 1
+at the destination host (so an ICMP PORT_UNREACHABLE message will
+be returned to terminate the route tracing).  If something is
+listening on a port in the default range, this option can be used
+to pick an unused port range.
+.TP
+.B \-r
+Bypass the normal routing tables and send directly to a host on an attached
+network.
+If the host is not on a directly-attached network,
+an error is returned.
+This option can be used to ping a local host through an interface
+that has no route through it (e.g., after the interface was dropped by
+.IR routed (8C)).
+.TP
+.B \-s
+Use the following IP address (which usually is given as an IP number, not
+a hostname) as the source address in outgoing probe packets.  On
+multi-homed hosts (those with more than one IP
+address), this option can be used to
+force the source address to be something other than the IP address
+of the interface the probe packet is sent on.  If the IP address
+is not one of this machine's interface addresses, an error is
+returned and nothing is sent. (See the
+.B \-i
+flag for another way to do this.)
+.TP
+.B \-t
+Set the
+.I type-of-service
+in probe packets to the following value (default zero).  The value must be
+a decimal integer in the range 0 to 255.  This option can be used to
+see if different types-of-service result in different paths.  (If you
+are not running 4.4bsd, this may be academic since the normal network
+services like telnet and ftp don't let you control the TOS).
+Not all values of TOS are legal or
+meaningful \- see the IP spec for definitions.  Useful values are
+probably
+.RB ` -t
+.IR 16 '
+(low delay) and
+.RB ` -t
+.IR 8 '
+(high throughput).
+.TP
+.B \-v
+Verbose output.  Received ICMP packets other than TIME_EXCEEDED and
+UNREACHABLEs are listed.
+.TP
+.B \-w
+Set the time (in seconds) to wait for a response to a probe (default 5
+sec.).
+.TP
+.B \-x
+Toggle ip checksums. Normally, this prevents traceroute from calculating
+ip checksums. In some cases, the operating system can overwrite parts of
+the outgoing packet but not recalculate the checksum (so in some cases
+the default is to not calculate checksums and using
+.B \-x
+causes them to be calcualted). Note that checksums are usually required
+for the last hop when using ICMP ECHO probes
+.RB ( \-I ).
+So they are always calculated when using ICMP.
+.TP
+.B \-z
+Set the time (in milliseconds) to pause between probes (default 0).
+Some systems such as Solaris and routers such as Ciscos rate limit
+icmp messages. A good value to use with this this is 500 (e.g. 1/2 second).
+.PP
+This program attempts to trace the route an IP packet would follow to some
+internet host by launching UDP 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
+.B \-m
+flag).  Three
+probes (change with
+.B \-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
+.B \-w
+flag), a "*" is printed for that
+probe.
+.PP
+We don't want the destination
+host to process the UDP probe packets 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
+.B \-p
+flag).

+
+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.
+.PP
+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:

+.RE
+
+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
+.BR !H ,
+.BR !N ,
+or
+.B !P
+(host, network or protocol unreachable),
+.B !S
+(source route failed),
+.B !F\-<pmtu>
+(fragmentation needed \- the RFC1191 Path MTU Discovery value is displayed),
+.B !X
+(communication administratively prohibited),
+.B !V
+(host precedence violation),
+.B !C
+(precedence cutoff in effect), or
+.B !<num>
+(ICMP unreachable code <num>).
+These are defined by RFC1812 (which supersedes RFC1716).
+If almost all the probes result in some kind of unreachable, traceroute
+will give up and exit.
+.PP
+This program is intended for use in network testing, measurement
+and management.
+It should be used primarily for manual fault isolation.
+Because of the load it could impose on the network, it is unwise to use
+.I traceroute
+during normal operations or from automated scripts.

+ * (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

+ * 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:

+ *     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...
