From [1] The story of PING: 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. [1] https://ftp.arl.army.mil/~m…
There was this story of a person who could ping a machine and he knew it was in his house, but for the love of God couldn't find the machine. It's a very short story, but he ends up looking at the pings not knowing where this machine is runnning.
