PING is an app most computers can run,
Showing lots of numbers, when it’s done.
Computer one calls then awaits a reply,
Computer two answers, "Oh, Hey, Hi!"
Computer one counts the time it did take,
Between its hello and it’s heard from its mate.
It does this three times, unless told to do more,
It adds them all up and gives you a score.
The sent, the received, and the lost are all shown,
The lost means computer two didn't pick up the phone.
If the score is really bad,
then the SysAdmin is sad,
Because they must now call their work,
Who’ll just say, "It’s not the network!"
PING times all the talking to there and back,
With an echo reply, which isn’t a true ACK.
Magic packets can do a really neat trick,
They can wake a computer and that's pretty slick.
If the computer is sleeping,
and the magic's just right,
the computer turns on by itself in the night.
Alas, there are times, when the echoes get lost.
So, the computer lets you know it tried at all cost.
The "Request timed out," the computer reports,
It heard nothing back on any of its ports.
It waited the specified time to live value,
Computer two must be in a heck of a snafu.
I hope you enjoyed and learned from my poem
