$NetBSD: CHANGES,v 1.2 2011/09/11 01:06:26 christos Exp $
@(#) Id: CHANGES,v 1.23 2000/12/14 06:53:11 leres Exp (LBL)
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.

.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
uses 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 \-a
Turn on AS# lookups for each hop encountered.
.TP
.B \-A
Turn on AS# lookups and use the given server instead of the default.
.TP
.B \-d
Turn on socket-level debugging.
.TP
.B \-D
Dump the packet data to standard error before transmitting it.
.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 \-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 \-l
Display the ttl value of the returned packet. This is useful for
checking for asymmetric routing.
.TP
.B \-m
Set the max time-to-live (max number of hops) used in outgoing probe
packets. The default value is taken from the
.I net.inet.ip.ttl
sysctl(3) variable.
.TP
.B \-M
If found, show the MPLS Label and the Experimental (EXP) bit for the hop.
.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 \-P
Set the "don't fragment" bit, and use the next hop mtu each time we get
the "need fragmentation" error, thus probing the path MTU.
.TP
.B \-q
Set the number of probe packets sent for each hop. By default, traceroute
sends three probe packets.
.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 (8)).
.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 calculated). 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 \*[Am] 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).
.PP
A sample use and output might be:

.RE
Note that lines 2 \*[Am] 3 are the same. This is due to a buggy
kernel on the 2nd hop system \- lilac-dmc.Berkeley.EDU \- that forwards
packets with a zero ttl (a bug in the distributed version
of 4.3BSD). Note that you have to guess what path
the packets are taking cross-country since the NSFNET (129.140)
doesn't supply address-to-name translations for its NSSes.

.RE
Note that the gateways 12, 14, 15, 16 \*[Am] 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 (HP-UX) 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 !\*[Lt]N\*[Gt]
(ICMP unreachable code \*[Lt]num\*[Gt]).
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.

This program is intended for use in network testing, measurement

It should be used primarily for manual fault isolation.
Because of the load it could impose on the network, it is unwise to use
