Clearly looks like the N800 is trying to establish a session with the Linux box. There are no networking problems to worry about so I believe it is a problem with the Linux config (or missing piece of software?). Also, I am not sure exactly what functions I should configure on each end. For example, what I remember from Palm for Synching was the user's name was required. That does not seem to be input-able on the N800 in Garnet. But it is required along with a PDA ID in the gnome-pilot initial config for the pda device to be synched.
