Does the hub have a DHCP server on it?
If no the you have to manually set IP addresses for the 2 computers
If yes then check to make sure that your getting a vaild IP address from it.

If you are getting a IP address can you ping the other computer?

Sounds like to me that the computers don't have IP addresses set, now I thought that rendezvous was supposed to get around that but maybe not. I know that here with my home network that when the computers all have IP addresses then rendezvous works in iChat and I can printer share.

if you have to manually set IP's then use numbers like this.

for your G4
IP address = 192.168.1.1
Subnetmask = 255.255.255.0

for your iMac
IP address = 192.168.1.2
subnetmaks = 255.255.255.0

Hope this helps
Good luck

That could be the problem, because if each of your computers are getting a IP from the cable provider, they may not be able to see each other over the network.  I'm not too sure on this, but that is what I believe may be happening.  The best thing I can tell you is go out on boxing day and see if you can get a deal on a Linksys Router, you'll get a firewall with it and your cable company will only see one computer hooked up to it, maybe costing you less?

looks that switch or hub wont do the job right, i also recommend u get a router, i got one at compusa for $60, netgear, and both my g4 400 tower and dell PII 450 both network fine. with the hub only one computer is on the web which might b causing it not to network well, with the router, ip's would be split into both computers from your single assigned ip, thus making both computers network more thoroughly. btw, im using OS X (10.2.3) and XP, if that helps.

You didn't say if anything else works.  I'd suggest trying to ping one machine from the other, since that'll tell you if you have any IP connectivity at all.  If that doesn't work, then nothing else will.  Getting a router/firewall with a built-in multiport switch is a great idea, and I've had very good luck with Linksys boxes (their small 4-port model is pretty cheap these days - around $60 I think).  Once you have IP connectivity, then start verifying the various network configurations of both machines, such as the sharing and firewall settings.  You should be able to do what you want, and it shouldn't be too hard.

Good luck, and let us know how it goes.
