I am taking my old PC and turning it into a server for my mac. I do Ubuntu Linux installed and am using internet sharing from my ibook to the pc via the ethernet port. I got the linux box to read my ibook, but I can't get the ibook to read the pc. Is there any special setting or configuration I am missing? Whenever I try to connect I get the message: The server may not exist or it is not operational at this time. Check the server name or IP address and try again. Anyone have exprience with this issue?
