The Story of the PING Program

This guy is the man.
He wrote ping while involved with the Army.
Amamzing.

And get this: "The best ping story I've ever heard was told to me at a USENIX conference, where a network administrator with an intermittent Ethernet had linked the ping program to his vocoder program, in essence writing:

ping goodhost | sed -e 's/.*/ping/' | vocoder

He wired the vocoder's output into his office stereo and turned up the volume as loud as he could stand. The computer sat there shouting 'Ping, ping, ping...' once a second, and he wandered through the building wiggling Ethernet connectors until the sound stopped. And that's how he found the intermittent failure."

Now there is a good idea.
That's why the unix command line kicks any GUI's @$$.
