Hey Ubuntu Forums,

I have currently set up one of my old machines (Dell Dimension 4600) to be primarily a Folding@Home machine, and as a server for other computers on my network. I want to have an external drive that is plugged into the Ubuntu box to be shared over the network to my MacBook, so that it can be used as a Time Machine backup drive. I don't even know where to start (fairly new to linux), or where I would find the setting to do this. Is this even possible to do?

Thanks in advance!
