"Pinging" a computer is one way to check and see if a
computer is on the network. Pings send a network request to a computer asking
it to respond (ICMP ECHO_REQUEST).
When you "ping" a computer, you need to know its name or its IP
address. Using the IP address is better than using the name, as it eliminates
the need to look up the name, but in practice, most people use the computer's
name.
- To ping a computer named www.dartmouth.edu from a UNIX machine, use the
command ping www.dartmouth.edu.
- To ping a computer from a Macintosh, use the program macping.
- To ping a computer from a Windows/PC machine, go to the MSDOS prompt and
use the command ping www.dartmouth.edu.
