Alessandro, Scp is "secure cp" and is a part of the ssh service. So if you have ssh access then you can use scp. From Windows you would be using winscp. Many hosts provide this but not all.
If you send files to the ops staff then they can coordinate the restart and any fallback planning, so that might be the best bet. Cheers -- Rick -- Sorry for being brief. Alternate email is rickleir at yahoo dot com
