Connecting My Powerbook to My Xbox



I am trying to connect my powerbook to my xbox (modded with Evolution X) in order to back up some of my iTunes downloads.

I have a standard cross-over cable which i have connected to my powerbook and my xbox, and I have downloaded a trial version of Yummy FTP in order to connect. I have entered in the IP address of my xbox (, port 21) which I got from the system settings on the xbox.

The user name and password used are both 'xbox', which I sourced from both my xbox and various websites.

I have also tried Cyberduck to connect as well with no luck.

Can anyone help?
