if you want to access the dreambox via ssh, please first connect via telnet protocol (port23), then do a "passwd" and set your desired password. After you've done this, you 're able to connect via ssh on port 22 with username "root" and "yourpassword" to connect.
Then you are also able to connect with the same credentials via ftp.
