ping
ping: [from the submariners' term for a sonar pulse] 1. n.
Slang term for a small network message (ICMP ECHO) sent by a
computer to check for the presence and alertness of another. The
Unix command `ping(8)' can be used to do this manually (note that
`ping(8)''s author denies the widespread folk etymology that the
name was ever intended as acronym for `Packet INternet Groper').
Occasionally used as a phone greeting. See ACK, also ENQ. 2.
vt. To verify the presence of. 3. vt. To get the attention of. 4.
vt. To send a message to all members of a mailing list requesting
an ACK (in order to verify that everybody's addresses are
reachable). "We haven't heard much of anything from Geoff, but he
did respond with an ACK both times I pinged jargon-friends." 5. n.
A quantum packet of happiness. People who are very happy tend to
exude pings; furthermore, one can intentionally create pings and aim
them at a needy party (e.g., a depressed person). This sense of
ping may appear as an exclamation; "Ping!" (I'm happy; I am emitting
a quantum of happiness; I have been struck by a quantum of
happiness). The form "pingfulness", which is used to describe
people who exude pings, also occurs. (In the standard abuse of
language, "pingfulness" can also be used as an exclamation, in which
case it's a much stronger exclamation than just "ping"!). Oppose
blargh.
The funniest use of `ping' to date 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, and got tired of having to run back to his console
after each cabling tweak to see if the ping packets were getting
through. So he used the sound-recording feature on the NeXT, then
wrote a script that repeatedly invoked `ping(8)', listened for an
echo, and played back the recording on each returned packet.
Result? A program that 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.
