.TP 20
\\fB\$1\\fR
# \\$2
..
.SH EXAMPLES
.TP 20
.B ping 192.168.1.1
# Ping host 192.168.1.1
.TP 20
.B ping www.minix3.org 500
# Ping www.minix3.org with 500 byte IP packets
.SH DESCRIPTION
.PP
Sends ICMP ECHO_REQUEST packets to the specified host and waits for a ECHO_REPLY.
Optionally, the length (size) of the IP packet can be specified. The default is
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 NAME
.Nm ping
.Nd send
.Tn ICMP ECHO_REQUEST
packets to network hosts
.Sh SYNOPSIS
.Nm
.Op Fl aCDdfLnoPQqRrv
.Op Fl c Ar count
.Op Fl E Ar policy
.Op Fl g Ar gateway
.Op Fl h Ar host
.Op Fl I Ar srcaddr
.Op Fl i Ar interval
.Op Fl l Ar preload
.Op Fl p Ar pattern
.Op Fl s Ar packetsize
.Op Fl T Ar ttl
.Op Fl t Ar tos
.Op Fl w Ar deadline
.Ar host
.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.
.Sh SEE ALSO
.Xr netstat 1 ,
.Xr icmp 4 ,
.Xr inet 4 ,
.Xr ip 4 ,
.Xr ifconfig 8 ,
.Xr routed 8 ,
.Xr spray 8 ,
.Xr traceroute 8
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.3 .
IPsec support was added by WIDE/KAME project.
.Sh BUGS
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).
.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
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
