often the acid test of whether you have a correctly configured and working network interface. Note that some sites explicitly filter out ICMP packets, so, for example, ping cnn.com won't work. <span>ping sends a packet every second and measures the time it takes to receive the return packet--like a submarine sonar ping.'' Over the Internet, you can get times in excess of 2 seconds if the place is remote enough. On a local LAN this delay will drop to under a millisecond.
