6. Edit the following: */5 * * * * transmission transmission-remote localhost:9091 -a /var/hda/files/torrents/*.torrent && rm -f /var/hda/files/torrents/*.torrent
add "--auch [username]:[password]" so the line becomes:
*/5 * * * * transmission transmission-remote localhost:9091 --auth [username]:[password] -a /var/hda/files/torrents/*.torrent && rm -f /var/hda/files/torrents/*.torrent
where the username and password are the ones you entered as rpc-username and rpc-password.
