ping
The ping command is used to determine whether or not a computer
is actually connected to the Internet. This is especially useful if you are trying
to contact a particular computer and are getting no response. The ping
command allows you to check and see if the machine is in fact "alive". For
example, if you wanted to know if the computer sundown in the
domain of sdsu.edu is active, you would type:
rohan% ping sundown.sdsu.edu
After you type this command, you will get one of three responses:
-
sundown.sdsu.edu is alive - the computer is on the Internet
and is responding
no answer from sundown.sdsu.edu - the computer is on the
Internet, but is not responding
ping: unknown host sundown.sdsu.edu - the computer is not
connected to the Internet
