Do you want the .torrent file, or the file it's pointing to?
Net::BitTorrent::File seems to just be for reading .torrent files, not for fetching them. You probably want a bittorrent client, or just scp.
Yes!
I'm Sorry! I didn't asked clearly! I need the file, that .torrent is pointing to! Maybe I need some bittorent client to install on server? And than using ssh-session to load that file, which is pointed from .torrent?
