if you have ssh, then you have sftp. start in your shell (start up 'terminal' from the applications folder, then 'cd desktop'. then sftp <username-on-ubuntu@ubuntu-computer-name>, then when you have entered your password, cd into the directory on the ubuntu system and 'get' the file or 'mget' the files (using standard unix path symbols) from that directory. they will magically all appear on your desktop and you can exit sftp by typing 'exit'.
