Ping is particularly useful when you're having trouble reaching a Web site or mail server on the Net.
Ping works the same way sonar does.
When you invoke a ping command, your system sends a few packets of data to the server you're testing. If it reaches the other side, it will come back telling you it was successful. If the packets cannot reach the other side, ping will give you an error message. First, make sure that you have dialed into the Internet. If this ping is successful, the problem is between the ISP and the distant server.
