I'm Don, a retired disabled senior.
All I want to do is move files back and forth between a laptop and a pc.
The PC is 2ghz, 1g ram, Mandriva 2005 LE.
The laptop is 1.7ghz, 512g ram, Mandriva 2005 LE.
ADSL with a router with 4 connections.
TightVNC came with Mandriva so that is what I'm trying to get working.

I need someone willing to lead me by the hand step by step from start to 
I did this, did that, read this, read that, hostname, address --
I do not understad networking, I simply don't get it.
