(用來檢測網絡遠端主機是否存在及判斷網絡是否正常的一種網絡檢測工具) 子彈飛過空中的聲音,報時的最後的一聲咻地發聲 ; (用來檢測網絡遠端主機是否存在及判斷網絡是否正常的一種網絡檢測工具) Ping n 1: a river in western Thailand; a major tributary of the Chao Phraya [ synonym: { Ping}, { Ping River}] 2: a sharp high- pitched resonant sound ( as of a sonar echo or a bullet striking metal) v 1: hit with a pinging noise; " The bugs pinged the lamp shade" 2: sound like a car engine that is firing too early; " the car pinged when I put in low- octane gasoline"; " The car pinked when the ignition was too far retarded" [ synonym: { pink}, { ping}, { knock}] 3: make a short high- pitched sound; " the bullet pinged when they struck the car" 4: contact, usually in order to remind of something; " I' ll ping my accountant-- April 15 is nearing" 5: send a message from one computer to another to check whether it is reachable and active; " ping your machine in the office" Ping \ Ping\, n. [ Probably of imitative origin.] The sound made by a bullet in striking a solid object or in passing through the air. [ 1913 Webster]
Ping \ Ping\, v. i. [ imp. & p. p. { Pinged}; p. pr. & vb. n. { Pinging}.] To make the sound called ping. [ 1913 Webster]
backfire \ backfire\, back fire \ back fire\ 1. A fire started ahead of a forest or prairie fire to burn only against the wind, so that when the two fires meet both must go out for lack of fuel. [ Webster 1913 Suppl.] 2. ( a) A premature explosion in the cylinder of a gas or oil engine during the exhaust or the compression stroke, tending to drive the piston in a direction reverse to that in which it should travel; also called a { knock} or { ping}. ( b) an explosion in the exhaust passages of an internal combustion engine. [ Webster 1913 Suppl. PJC] Backfire (ping, originally contrived to match
submariners' term for the sound of a returned sonar pulse) A
program written in 1983 by Mike Muuss (who also wrote {TTCP})
used to test reachability of destinations by sending them one,
or repeated, {ICMP} echo requests and waiting for replies.
Since ping works at the {IP} level its server-side is often
implemented entirely within the {operating system} {kernel}
and is thus the lowest level test of whether a remote host is
alive. Ping will often respond even when higher level,
{TCP}-based services cannot.
Sadly, Mike Muuss was killed in a road accident on 2000-11-20.
The term is also used as a verb: "Ping host X to see if it is
up."
The {Unix} command "ping" can be used to do this and to
measure round-trip delays.
The funniest use of "ping" was described in January 1991 by
Steve Hayman on the {Usenet} group comp.sys.next. He was
trying to isolate a faulty cable segment on a {TCP/IP}
{Ethernet} hooked up to a {NeXT} machine. Using the sound
recording feature on the NeXT, he wrote a {script} that
repeatedly invoked ping, listened for an echo, and played back
the recording on each returned {packet}. This caused the
machine to repeat, over and over, "Ping ... ping ... ping ..."
as long as the network was up. He turned the volume to
maximum, ferreted through the building with one ear cocked,
and found a faulty tee connector in no time.
Ping did not stand for "Packet InterNet Groper", Dave Mills
offered this {backronym} expansion some time later.
See also {ACK}, {ENQ}, {traceroute}, {spray}.
