I have a very simple home network, consisting of two machines. The first is a new linux box that acts as a router and connects to the outside world, and the second is an older machine that dual boots to linux or Win98. The problem I'm having is that when I attempt to transfer a large file between the two machines, the older machine locks up with a pattern of vertical lines across the screen. This happens when the older machine is running MS or Linux. I have connected the two machines via an ethernet switch and directly with a crossover cable, and the problem persists. I'm hoping that someone with more experience in setting up networks than I can shed some light as to a possible cause of this problem. Any help is appreciated.
