I have an old dell desktop which I have installed Ubuntu 11.04 on and I have it plugged into my wireless router. I'm able to VNC into the machine using 'Chick of the VNC'. I want to use it as a Time Capsule to back up my Mac Book Pro, but when my Mac book scans for a device nothing is found.
I followed this tutorial: Configuring Ubuntu to Store Time Machine Backups to setup the Ubuntu machine as a server.
