Ping is a program that helps tell if the network is working. But it provides very little information. I work in a company that supplies networks. So people say the worst things like – there was 10% packet loss when I used Ping. Or worse, I sent these humungus pings and they all failed!
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. … If I’d known then that it would be my most famous accomplishment in life, I might have worked on it another day or two and added some more options.
