If you wish, you may use the root account on your Linode to perform file transfers, although you may need to change file ownership and permissions on the server after doing so. You’ll need to make sure your Linode is running an SSH daemon (all Linodes run an OpenSSH server by default), and that you have a user account on the server before following these instructions. Cyberduck can send both your login credentials and file transfers over the network securely encrypted (provided you’re using SFTP), while standard FTP clients send this information as plaintext. This tool allows you to securely transfer files to and from your Linode using an encrypted channel, avoiding the security problems and usability issues inherent in traditional FTP client/server systems.
It implements several file transfer protocols, most notably SFTP via SSH. Cyberduck is a free, open source file transfer program written for Mac OS X.
