Hi,
You should read the scp manpage. Scp is a special version of cp using ssh.
The best explanation is an example, so imagine you are on a machine called "client" and you want to download a file named "file" in your home directory in the distant machine called "server" :
$>scp your_login@server:file .
and if you want to put a file to the server :
$>scp file your_login@server:
There are other parameters, see in the manpage, good luck
