I have a Mac OS 9 and a Mac OS X.
The OS 9 has a dialup internet connection.
I need share files between both computers (from each one to each other) and print from OS X in an OS 9's printer.
I connected them through cross over in the ethernet port.
Then I activate file sharing (OS9) and give an IP adress to (OS X) but now when I go to TCP/IP on OS 9 there are two options a) Ethernet (I can assign an IP address) or b) PPP (Has the IP assigned for my Internet provider).
If I choose Ethernet the file sharing works but the internet does not. If I choose PPP the dialup connection works but the file sharing does not.
