|
||||
30 bytes. (Note, the 14 byte Ethernet header will make this a 44 byte packet.)
|
||||
.SH OPTIONS
|
||||
.IP length
|
||||
Size (in bytes) of the transmitted ICMP packet. The default length of the IP
|
||||
packet is 30 bytes. (Adding the ethernet header will result in a 44 byte
|
||||
packet being transmitted.)

.Sh DESCRIPTION
|
||||
.Nm
|
||||
uses the
|
||||
.Tn ICMP
|
||||
protocol's mandatory
|
||||
.Tn ECHO_REQUEST
|
||||
datagram to elicit an
|
||||
.Tn ICMP ECHO_RESPONSE
|
||||
from a host or gateway.
|
||||
.Tn ECHO_REQUEST
|
||||
datagrams (``pings'') have an IP and
|
||||
.Tn ICMP
|
||||
header,
|
||||
followed by a
|
||||
.Dq struct timespec
|
||||
and then an arbitrary number of ``pad'' bytes used to fill out the
|
||||
packet.
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl a
|
||||
Emit an audible beep (by sending an ascii BEL character to the
|
||||
standard error output) after each non-duplicate response is received.
|
||||
This is disabled for flood pings as it would probably cause temporary
|
||||
insanity.
|
||||
.It Fl C
|
||||
Send timestamps in compat format; two 32 bit words in little endian format,
|
||||
the first one representing seconds, and the second one representing
|
||||
microseconds.
|
||||
.It Fl c Ar count
|
||||
Stop after sending (and waiting the specified delay to receive)
|
||||
.Ar count
|
||||
.Tn ECHO_RESPONSE
|
||||
packets.
|
||||
.It Fl D
|
||||
Set the
|
||||
.Dv Don't Fragment
|
||||
bit in the IP header.
|
||||
This can be used to determine the path MTU.
|
||||
.It Fl d
|
||||
Set the
|
||||
.Dv SO_DEBUG
|
||||
option on the socket being used.
|
||||
.It Fl E Ar policy
|
||||
Use IPsec policy specification string
|
||||
.Ar policy
|
||||
for packets.
|
||||
For the format of specification string, please refer
|
||||
.Xr ipsec_set_policy 3 .
|
||||
Please note that this option is same as
|
||||
.Fl P
|
||||
in KAME/FreeBSD and KAME/BSDI
|
||||
(as
|
||||
.Fl P
|
||||
was already occupied in
|
||||
.Nx ) .
|
||||
.It Fl f
|
||||
Flood ping.
|
||||
Outputs packets as fast as they come back or one hundred times per second,
|
||||
whichever is more.
|
||||
For every
|
||||
.Tn ECHO_REQUEST
|
||||
sent a period ``.'' is printed, while for every
|
||||
.Tn ECHO_REPLY
|
||||
received a backspace is printed.
|
||||
This provides a rapid display of how many packets are being dropped.
|
||||
Only the super-user may use this option.
|
||||
.Bf -emphasis
|
||||
This can be very hard on a network and should be used with caution.
|
||||
.Ef
|
||||
.It Fl g Ar gateway
|
||||
Use Loose Source Routing to send the ECHO_REQUEST packets via
|
||||
.Ar gateway .
|
||||
.It Fl h Ar host
|
||||
is an alternate way of specifying the target host instead of as the
|
||||
last argument.
|
||||
.It Fl I Ar srcaddr
|
||||
Set the source IP address to
|
||||
.Ar srcaddr
|
||||
which can be a hostname or an IP number.
|
||||
For multicast datagrams, it also specifies the outgoing interface.
|
||||
.It Fl i Ar interval
|
||||
Wait
|
||||
.Ar interval
|
||||
seconds
|
||||
.Em between sending each packet .
|
||||
The default is to wait for one second between each packet,
|
||||
except when the -f option is used the wait interval is 0.01 seconds.
|
||||
.It Fl L
|
||||
Disable loopback when sending to multicast destinations,
|
||||
so the transmitting host doesn't see the ICMP requests.
|
||||
.It Fl l Ar preload
|
||||
If
|
||||
.Ar preload
|
||||
is specified,
|
||||
.Nm
|
||||
sends that many packets as fast as possible before falling into its normal
|
||||
mode of behavior.
|
||||
Only the super-user may use this option.
|
||||
.It Fl n
|
||||
Numeric output only.
|
||||
No attempt will be made to look up symbolic names for host addresses.
|
||||
.It Fl o
|
||||
Exit successfully after receiving one reply packet.
|
||||
.It Fl P
|
||||
Use a pseudo-random sequence for the data instead of the default,
|
||||
fixed sequence of incrementing 8-bit integers.
|
||||
This is useful to foil compression on PPP and other links.
|
||||
.It Fl p Ar pattern
|
||||
You may specify up to 16 ``pad'' bytes to fill out the packet you send.
|
||||
This is useful for diagnosing data-dependent problems in a network.
|
||||
For example,
|
||||
.Dq Li \-p ff
|
||||
will cause the sent packet to be filled with all
|
||||
ones.
|
||||
.It Fl Q
|
||||
Do not display responses such as Network Unreachable ICMP messages
|
||||
concerning the ECHO_REQUESTs sent.
|
||||
.It Fl q
|
||||
Quiet output.
|
||||
Nothing is displayed except the summary lines at startup time and
|
||||
when finished.
|
||||
.It Fl R
|
||||
Record Route.
|
||||
Includes the
|
||||
.Tn RECORD_ROUTE
|
||||
option in the
|
||||
.Tn ECHO_REQUEST
|
||||
packet and displays the route buffer on returned packets.
|
||||
This should show the path to the target host and back, which is
|
||||
especially useful in the case of asymmetric routing.
|
||||
Note that the IP header is only large enough for nine such addresses,
|
||||
and only seven when using the
|
||||
.Fl g
|
||||
option.
|
||||
This is why it was necessary to invent
|
||||
.Xr traceroute 8 .
|
||||
Many hosts ignore or discard this option.
|
||||
.It Fl 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
|
||||
.Xr routed 8 ) .
|
||||
.It Fl s Ar packetsize
|
||||
Specifies the number of data bytes to be sent.
|
||||
The default is 56, which translates into 64
|
||||
.Tn ICMP
|
||||
data bytes when combined
|
||||
with the 8 bytes of
|
||||
.Tn ICMP
|
||||
header data.
|
||||
The maximum allowed value is 65467 bytes.
|
||||
.It Fl T Ar ttl
|
||||
Use the specified time-to-live.
|
||||
.It Fl t Ar tos
|
||||
Use the specified hexadecimal type of service.
|
||||
.It Fl v
|
||||
Verbose output.
|
||||
.Tn ICMP
|
||||
packets other than
|
||||
.Tn ECHO_RESPONSE
|
||||
that are received are listed.
|
||||
.It Fl w Ar deadline
|
||||
Specifies a timeout, in seconds, before ping exits regardless of
|
||||
how many packets have been sent or received.
|
||||
.El
|
||||
.Pp
|
||||
When using
|
||||
.Nm
|
||||
for fault isolation, it should first be run on the local host, to verify
|
||||
that the local network interface is up and running.
|
||||
Then, hosts and gateways further and further away should be ``pinged''.
|
||||
.Pp
|
||||
Round-trip times and packet loss statistics are computed.
|
||||
If duplicate packets are received, they are not included in the packet
|
||||
loss calculation, although the round trip time of these packets is used
|
||||
in calculating the minimum/average/maximum round-trip time numbers.
|
||||
.Pp
|
||||
When the specified number of packets have been sent (and received) or
|
||||
if the program is terminated with a
|
||||
.Dv SIGINT ,
|
||||
a brief summary is displayed.
|
||||
The summary information can be displayed while
|
||||
.Nm
|
||||
is running by sending it a
|
||||
.Dv SIGINFO
|
||||
signal (see the
|
||||
.Dq status
|
||||
argument for
|
||||
.Xr stty 1
|
||||
for more information).
|
||||
.Pp
|
||||
.Nm
|
||||
continually sends one datagram per second, and prints one line of
|
||||
output for every ECHO_RESPONSE returned.
|
||||
On a trusted system with IP
|
||||
Security Options enabled, if the network idiom is not MONO,
|
||||
.Nm
|
||||
also prints a second line containing the hexadecimal representation
|
||||
of the IP security option in the ECHO_RESPONSE.
|
||||
If the
|
||||
.Fl c
|
||||
count option is given, only that number of requests is sent.
|
||||
No output is produced if there is no response.
|
||||
Round-trip times and packet loss statistics are computed.
|
||||
If duplicate packets are received,
|
||||
they are not included in the packet loss calculation,
|
||||
although the round trip time of these packets is used in calculating
|
||||
the minimum/average/maximum round-trip time numbers.
|
||||
When the specified number of packets have been sent (and received) or if
|
||||
the program is terminated with an interrupt (SIGINT), a brief
|
||||
summary is displayed.
|
||||
When not using the
|
||||
.Fl f
|
||||
(flood) option, the first interrupt, usually generated by control-C or DEL,
|
||||
causes
|
||||
.Nm
|
||||
to wait for its outstanding requests to return.
|
||||
It will wait no longer than the longest round trip time
|
||||
encountered by previous, successful pings.
|
||||
The second interrupt stops ping immediately.
|
||||
.Pp
|
||||
This program is intended for use in network testing, measurement and
|
||||
management.
|
||||
Because of the load it can impose on the network, it is unwise to use
|
||||
.Nm
|
||||
during normal operations or from automated scripts.
|
||||
.Sh ICMP PACKET DETAILS
|
||||
An IP header without options is 20 bytes.
|
||||
An
|
||||
.Tn ICMP
|
||||
.Tn ECHO_REQUEST
|
||||
packet contains an additional 8 bytes worth of
|
||||
.Tn ICMP
|
||||
header followed by an arbitrary amount of data.
|
||||
When a
|
||||
.Ar packetsize
|
||||
is given, this indicated the size of this extra piece of data (the
|
||||
default is 56).
|
||||
Thus the amount of data received inside of an IP packet of type
|
||||
.Tn ICMP
|
||||
.Tn ECHO_REPLY
|
||||
will always be 8 bytes more than the requested data space (the
|
||||
.Tn ICMP
|
||||
header).
|
||||
.Pp
|
||||
If the data space is at least
|
||||
.Dv sizeof(struct timespec)
|
||||
(16) large,
|
||||
.Nm
|
||||
uses the first
|
||||
.Dv sizeof(struct timespec)
|
||||
bytes to include a timestamp to compute round trip times.
|
||||
Otherwise if the data space is at least eight bytes large (or the
|
||||
.Fl C
|
||||
flag is specified),
|
||||
.Nm
|
||||
uses the first eight bytes of this space to include a timestamp to compute
|
||||
round trip times.
|
||||
If there are not enough bytes of pad no round trip times are given.
|
||||
.Sh DUPLICATE AND DAMAGED PACKETS
|
||||
.Nm
|
||||
will report duplicate and damaged packets.
|
||||
Duplicate packets should never occur, and seem to be caused by
|
||||
inappropriate link-level retransmissions.
|
||||
Duplicates may occur in many situations and are rarely (if ever) a
|
||||
good sign, although the presence of low levels of duplicates may not
|
||||
always be cause for alarm.
|
||||
.Pp
|
||||
Damaged packets are obviously serious cause for alarm and often
|
||||
indicate broken hardware somewhere in the
|
||||
.Nm
|
||||
packet's path (in the network or in the hosts).
|
||||
.Sh TRYING DIFFERENT DATA PATTERNS
|
||||
The (inter)network layer should never treat packets differently depending
|
||||
on the data contained in the data portion.
|
||||
Unfortunately, data-dependent problems have been known to sneak into
|
||||
networks and remain undetected for long periods of time.
|
||||
In many cases the particular pattern that will have problems is something
|
||||
that doesn't have sufficient ``transitions'', such as all ones or all
|
||||
zeros, or a pattern right at the edge, such as almost all zeros.
|
||||
It isn't necessarily enough to specify a data pattern of all zeros (for
|
||||
example) on the command line because the pattern that is of interest is
|
||||
at the data link level, and the relationship between what you type and
|
||||
what the controllers transmit can be complicated.
|
||||
.Pp
|
||||
This means that if you have a data-dependent problem you will probably
|
||||
have to do a lot of testing to find it.
|
||||
If you are lucky, you may manage to find a file that either can't be sent
|
||||
across your network or that takes much longer to transfer than other
|
||||
similar length files.
|
||||
You can then examine this file for repeated patterns that you can test
|
||||
using the
|
||||
.Fl p
|
||||
option of
|
||||
.Nm .
|
||||
.Sh TTL DETAILS
|
||||
The
|
||||
.Tn TTL
|
||||
value of an IP packet represents the maximum number of IP routers
|
||||
that the packet can go through before being thrown away.
|
||||
In current practice you can expect each router in the Internet to decrement
|
||||
the
|
||||
.Tn TTL
|
||||
field by exactly one.
|
||||
.Pp
|
||||
The
|
||||
.Tn TCP/IP
|
||||
specification states that the
|
||||
.Tn TTL
|
||||
field for
|
||||
.Tn TCP
|
||||
packets should
|
||||
be set to 60, but many systems use smaller values
|
||||
.Po
|
||||
.Bx 4.3
|
||||
uses 30,
|
||||
.Bx 4.2
|
||||
used 15
|
||||
.Pc .
|
||||
.Pp
|
||||
The maximum possible value of this field is 255, and most
|
||||
.Ux
|
||||
systems set the
|
||||
.Tn TTL
|
||||
field of
|
||||
.Tn ICMP ECHO_REQUEST
|
||||
packets to 255.
|
||||
This is why you will find you can ``ping'' some hosts, but not reach them
|
||||
with
|
||||
.Xr telnet 1
|
||||
or
|
||||
.Xr ftp 1 .
|
||||
.Pp
|
||||
In normal operation ping prints the ttl value from the packet it receives.
|
||||
When a remote system receives a ping packet, it can do one of three things
|
||||
with the
|
||||
.Tn TTL
|
||||
field in its response:
|
||||
.Bl -bullet
|
||||
.It
|
||||
Not change it; this is what Berkeley
|
||||
.Ux
|
||||
systems did before the
|
||||
.Bx 4.3 tahoe
|
||||
release.
|
||||
In this case the
|
||||
.Tn TTL
|
||||
value in the received packet will be 255 minus the
|
||||
number of routers in the round-trip path.
|
||||
.It
|
||||
Set it to 255; this is what current Berkeley
|
||||
.Ux
|
||||
systems do.
|
||||
In this case the
|
||||
.Tn TTL
|
||||
value in the received packet will be 255 minus the
|
||||
number of routers in the path
|
||||
.Em from
|
||||
the remote system
|
||||
.Em to
|
||||
the
|
||||
.Nm Ns Em ing
|
||||
host.
|
||||
.It
|
||||
Set it to some other value.
|
||||
Some machines use the same value for
|
||||
.Tn ICMP
|
||||
packets that they use for
|
||||
.Tn TCP
|
||||
packets, for example either 30 or 60.
|
||||
Others may use completely wild values.
|
||||
.El
|
||||
.Sh EXIT STATUS
|
||||
.Nm
|
||||
returns 0 on success (the host is alive),
|
||||
and non-zero if the arguments are incorrect or the host is not responding.

The
|
||||
.Nm
|
||||
command appeared in
|
||||
.Bx 4.3 .
|
||||
IPsec support was added by WIDE/KAME project.

|
||||
Flood pinging is not recommended in general, and flood pinging a broadcast
|
||||
or multicast address should only be done under very controlled conditions.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
program has evolved differently under different operating systems,
|
||||
and in some cases the same flag performs a different function
|
||||
under different operating systems.
|
||||
The
|
||||
.Fl t
|
||||
flag conflicts with
|
||||
.Fx .
|
||||
The
|
||||
.Fl a , c , I , i ,
|
||||
.Fl l , P , p , s ,
|
||||
and
|
||||
.Fl t
|
||||
flags conflict with
|
||||
.Sy Solaris .
|
||||
.Pp
|
||||
Some hosts and gateways ignore the
|
||||
.Tn RECORD_ROUTE
|
||||
option.
|
||||
.Pp
|
||||
The maximum IP header length is too small for options like
|
||||
.Tn RECORD_ROUTE
|
||||
to
|
||||
be completely useful.
|
||||
There's not much that that can be done about this, however.

$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).

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

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

|

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
|

.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.

# Perl script to convert a standard distribution directory for traceroute into
|

# a NetBSD source tree.
|

#
|

# This is done as a script so that as each distribution is released,
|

# only changes from the previous one need to be dealt with as
|

# modifications to this script and related files. This should
|

# reduce the cost of updating from a new release of traceroute by an
|

# order of magnitude (or more?)

# SRCDIR - traceroute source directory

# TARGETDIR - name of the high level directory to make
