knoppix standard includes one bittorrent client, but is only text mode, no gui. The name is "btlaunchmany".

You will need access to the hard disk with read permissions (right click in the desktop icons). Then launch a console, move to the selected disk (cd /mnt/hda1) and launch the bt client:

btlaunchmay .

The "." is to indicate to the program where the torrent files will be and where to download the files. finally get some torrents and save them in the selected hard disk. The client will begin to download any torrent file found in the selected directory.
