I have a set up in my home with a dell desktop downstairs attached to the router with internet and printers and stuff. We have three laptops set up wirelessly, one of them an ibook G4, which is mine. I also have an old PC I want to run linux on and connect to the internet. Is there any way i can share a connection with my ibook? It may have been easier but there's one problem: The old pc has no ethernet port! ugh. Is there anyway to bridge the connection over usb or the modem port? I'm not too worried about the printer sharing or anything on the old machine (yet), I'm more just worried about getting an internet connection. Thanks a bunch.
