Yes, it's true! I'm the author of ping for UNIX. Ping is a little
thousand-line hack that I wrote in an evening which practically everyone seems
to know about. :-)
I named it after the sound that a sonar makes, inspired by the whole principle
of echo-location. In college I'd done a lot of modeling of sonar and radar
systems, so the "Cyberspace" analogy seemed very apt. It's exactly the same
paradigm applied to a new problem domain: ping uses timed IP/ICMP ECHO_ |
