PING(8) System Manager's Manual
PING(8)
NAME
ping - send ICMP ECHO_REQUEST packets to network hosts
SYNOPSIS
ping [-dfnqrvR] [-c count] [-i wait] [-l preload] [-p pattern]
[-s packetsize]
DESCRIPTION
Ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit
an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams
(``pings'') have an IP and ICMP header, followed by a ``struct
timeval''
and then an arbitrary number of ``pad'' bytes used to fill out the
packet. The options are as follows: Other options are:
-c count
Stop after sending (and receiving) count ECHO_RESPONSE packets.
-d Set the SO_DEBUG option on the socket being used.
-f Flood ping. Outputs packets as fast as they come back or one
hundred times per second, whichever is more. For every
ECHO_REQUEST sent a period ``.'' is printed, while for ever
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. This can be very hard on a
net
work and should be used with caution.
-i wait
Wait wait seconds between sending each packet. The default is
to
wait for one second between each packet. This option is incom
patible with the -f option.
-l preload
If preload is specified, ping sends that many packets as fast
as
possible before falling into its normal mode of behavior. Only
the super-user may use this option.
-n Numeric output only. No attempt will be made to lookup
symbolic
names for host addresses.
-p 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, ``-p ff'' will cause the sent packet to
be
filled with all ones.
-q Quiet output. Nothing is displayed except the summary lines at
startup time and when finished.
-R Record route. Includes the RECORD_ROUTE option in the
ECHO_REQUEST packet and displays the route buffer on returned
packets. Note that the IP header is only large enough for nine
such routes. Many hosts ignore or discard this option.
-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
