I looked at NFS. It seems to be a good alternative, I don't need encryption. I want to use USB connection. I've been using Qt Mobile Hotspot because it enables USB networking, that way I can use Nautilus to access files on the N900.

My PC and N900 can't see each other. The network manager in Ubuntu just keeps trying to connect to my N900 without success. What would be the exact steps I need to do to get it to work? I have KP51r1 + CSSU-T on my N900.
