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

(b) an explosion in the exhaust passages of an internal

[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}.
