.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 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

||||
.Fl l , P , p , s ,
|
||||
and
|
||||
.Fl t
|
||||
flags conflict with
|
||||
.Sy Solaris .
|
||||
.Pp
|
||||
Some hosts and gateways ignore the
