Troubleshooting Network Problems

http://www.linuxjournal.com

Back when I worked in the Network Operations department at one of my previous jobs, we used to chuckle when a customer would call us reporting that “the Internet is down.” Now, I realize that there are otherwise intelligent computer users out there who don't understand why that might cause a technician to chuckle, and I'm not trying to make fun of them.
