4.1.6 ping Command
Overview Sends an ICMP ECHO_REQUEST packet to a host on
the network.
Syntax ping [-dfnoqrvDPQRL] [-c count] [-g gateway] [-I interval]
[-l ifaddr] [-l preload] [-p pattern] [-s packetsize] [-t tos]
[-T ttl] [-w maxwait] <host>
Parameter(s) -c count = Stops sending ECHO_RESPONSE packets
after sending out the packet for as many times as
specified by the count parameter (and after waiting for
the specified delay for a response).
-d = Sets the SO_DEBUG option when using socket.
-D = Sets the Don’t Fragment bit of the IP header. This
can be used to limit the MTU of that path.
-f = Flood ping. Sends the output out immediately after a
packet returns or 100 times within a second; the faster
of the two. The "." character is displayed for every
ECHO_REQUEST packet sent, whereas a backspace
is output for every ECHO_REPLY packet received.
Therefore, you can quickly see how many packets
have been lost. Since this puts a heavy load on the
network, use this with caution.
-g gateway = Sends ECHO_REQUEST packets through
the gateway using Loose Source Routing.
-I interval = Sends packets in intervals of the specified
seconds. By default, packets are sent in intervals of 1
second; however, the -f option is an exception where
packets are sent every 0.01 seconds.
-l ifaddr = Sends multicast datagrams to the network
interface specified by the host name or IP address.
-h host = An alternative method of specifying the target
host name for the last argument.
-l preload = Before going into normal operation mode,
this sends a certain number of packets specified by
preload as fast as possible.
-L = Disables loop back for multicast interface
destinations so that the source host cannot receive
ICMP requests.
-n = Only outputs numeric values. This does not look up
the symbol name of the host address.
-o = Exits upon receiving one response packet.
-p pattern = Specifies up to 16 bytes to send out for the
“pad" part of the outgoing packet. This is effective
when diagnosing a data-dependent problem on the
network. For example, "-p ff" fills the packets with 1's.
-P = By default, the data part uses an incremented
sequence of 8-bit integers, but this uses a
pseudo-random sequence for the data part. This is
effective when disabling compression for PPP and
other links.
-q = Controls the output. Other than the few lines content
displayed at startup and finish, nothing is displayed.
-Q = Does not display ICMP responses such as
