Great article... unfortunately, I have a weird problem.
I'm using OS 10.3.X. I have a laptop that is connected to the internet via the ethernet and bought a used IMac (also using OS 10.3) and tried to connect the two together using the FireWire. I followed the instructions exactly. Both computers say that the connection via FireWire is active and that I am connected to the internet. However, when I open Safari on the second computer, I can't connect to anything. I checked my firewalls and there's nothing turned on.
I know I'm a Mac newbie, but this does seem a bit weird to me. I would be eternally grateful if anyone could help me with this problem.
