ping doesnt work

Hi all,

I was working on a utility which plays a sound when the internet connection is disconnected, well I though I would ping a site, until I get an error, then provoke the sound function. But then I found out that ping doesnt work at all although all other services work.

Even when I'm connected it says

root@darkstar:~# ping http://www.google.com
ping: unknown host http://www.google.com

It says the same when I'm not connected, Whats the problem

try pinging google by google.com instead of http://www.google.com

root@darkstar:~# ping google.com
PING google.com (216.239.39.99) 56(84) bytes of data.

it worked! But why, doesnt it accept the full address

Because http is not part of an address, it's a protocol
that you instruct the browser to use for contacting an
actual ip address ... similariliy, if you tried
ping www.google.com/linux it wouldn't work either,
because /linux is just a reference to a location on
the server with the IP address www.google.com

The example is a bit far fetched, but think of the address
(www.xxx.com) as a TV set, http and https are different
access-methods and the bits after the first / are the channels.

Cheers,
Tink
