Ping of Death
Ping of Death (pêng`
ev deth') noun

Beloved to network administrators around the world, Ping was originally a utility that worked with the legendary BSD version of Unix created at Berkeley, but is now an essential part of almost every operating system. Functionally, it is the simplest of tools -- it sends a single packet of information to an Internet address to see if that address is reachable. As a debugger of Internet connections, Ping was/is invaluable.
Ping's usefulness was so
important that the term quickly became a part of geek jargon. To "ping"
a person meant to contact
that person via any means. "Ping me again if you don't hear from me about
your question tomorrow," one hacker
might say to another.
Engineers at Goddard Space Flight Center in Greenbelt, Md., successfully contacted UoSAT-12 spacecraft through a ground station in Surrey, England, using Internet ping packets. The project, called Operating Missions as Nodes on the Internet (OMNI), was the first time that a spacecraft ever had its own Internet address and was a fully RFC-compliant active node on the Internet.
[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.
