is it possible to use a xbox link cable to ftp?

[JiveTurkey]

Ethernet connections? I don't really know any other possible way to connect to an Xbox.

You are doing at least one of the following wrong:

using the wrong cable - like a cross when you need straight or vice versa

using a bad cable

using the wrong IP address

mistyping the IP address

using wrong protocol

Check all of these things but if I had to take a wild guess I would probably say you are trying the wrong address. What address, what kind of cable and whats on each end of it would help.
