TICKET ARCHIVE -> Networking G4 Powerbook (OSX 10.3.9) and G3 (OS 8.6)
Rosy - Nov 27, 2005 - 2:28 pm
About two years ago I successfully networked together a G4 Powerbook (running OSX 10.3.9) and a G3 (running OS 8.6), and until now this arrangement has been working perfectly. I use an Ethernet hub and cables to make the connection.
A few days ago I had to reboot following a split-second power cut, and the network failed to establish itself. I haven't been able to re-establish it since. During this very short power cut the G3 lost power completely, although the laptop, of course, continued uninterrupted. Since the problem showed up as soon as I next needed to establish the network connection, I am assuming that the power cut or surge perhaps had an effect on some of the settings.
I have two other computers (PCs) networked to the Powerbook on a separate wireless network, using Airport and a Netgear router. I use this network to access the Internet from the G4. The G3 doesn't have Internet access, but I'm quite happy with that arrangement.
The two networks have been working simltaneously for the whole two years, so I have no reason to suppose that the wireless network has any relevance to this new problem.The wireless connections between the G4 Powerbook and the PCs are still working fine, and the problem is only between the G4 Powerbook and the G3.
I've tried to make sure that the AppleTalk settings on both Powerbook and G3 are set, that file sharing is on, and that the cables are attached correctly (both lights on the hub are on). The network status panel on the Powerbook shows a green light next to Ethernet, which makes me assume that the connection is OK from the the Powerbook end.
(For the record, I've only ever been able to access the G3 hard disc from the G4 Powerbook, never the other way round, but I've been perfectly happy with this arrangement as it has been adequate for my needs.)
Are you able to help out with the precise settings required on both the G4 and the G3 so that the connection can be re-established? I fear that I may have changed the settings from how they originally were on both computers, in my panicked quest to remake the connection, and have lost sight of how the settings originally were. I'm particularly unsure whether I should be using a TCP/IP setting on either computer and am extremely confused about which Ethernet, AppleTalk, and/or TCP/IP settings I should be using. (For the record, I don't use Appletalk Zones or Users and Groups. The connection is extremely straightforward, as it's just me connecting my two workhorses together).
Mac OSX Help exhorts me to talk to my network administrator, but since I'm a freelance designer in control of my own equipment, I'm the administrator myself! Why do these makers always assume we end users are incapable, and fall back on this feeble cop-out of invoking some mythical "administrator" to solve our problems? Where does the unfortunate administrator get the information, and why can't end users have it direct? You are my only hope!
Thank you

I think the key to your problem is that you must have a valid IP address set in OS X before appletalk and ethernet will work.
On OS X, in Network prefs > Show Built-in ethernet > TCP/IP tab, set Configure IPv4 manually and enter this IP address - 192.168.1.10. Now go to appletalk tab and make sure it is On.
Go to Sharing prefs and make sure personal file sharing is On.
On OS 8/9, Go to TCP/IP control panel and set configure manually and enter IP address 192.168.1.11. Go to Appletalk Control Panel and set it to use ethernet. Go to File sharing and turn on file sharing.
That should do it. From OS 8/9, you may find it helps to enter the Server IP address in the Chooser > Appleshare right side window.

Thank you for the response. The tip on the IP addresses is very helpful. I've put these in, and doublechecked the other settings. However, I still can't make the connection.
Can you confirm something: on Mac OS 8.6 the TCP/IP control panel has four options under the Connect via tab. They are AppleTalk (MacIP); CompuservePPP; Ethernet; and PPP. Each of them offers the ability to enter the IP address manually. It seems most likely that it should be the AppleTalk (MacIP) tab that I should use, and I tried this first, but it failed to make the connection. I've also tried each of the other options, just in case, restarting between each change, but nothing works with them either.
Also, attempting to put the IP adress in the Chooser > Appleshare window sets a progress bar running as it tries to contact the server, but it too fails. However, I have never been able to access the G4 from the G3, only ever the other way round, so this doesn't surprise me.
Grateful for any further ideas you may have. So frustrating, since it's been networking fine for the past two years.
Many thanks

You want to set up ethernet, and not MacIP.

I have indeed already tried putting in the IP address you indicated using the Ethernet configuration in the TCP/IP control panel, but it still doesn't work.
Can there be anything else that I'm missing?

Let's try some low-level troubleshooting.
Use the Terminal on OS X, and type this command:
ping 192.168.1.11
tell me if it gives repeating messages or errors - Use Control-C to stop the repeating messages.

It's giving the repeated message:
ping:sendto:Host is down

OK, that's telling us that a cable or the hub might be bad. Or the OS 8 computer's ethernet isn't setup/working. From this point, there's no way to tell which is bad except try every piece of the network with some other computer.
Good luck.

To start, try ethernet cables direct computer to computer, eliminating the hub from the net.

Can I use the same cable from computer to computer a I do from computer to hub?
gsahli - Nov 29, 2005 - 12:09 pm
Yes, you can use the same cable(s) (older computers required crossover cables - yours don't).

Success! Connecting the G4 to the G3 by direct ethernet cable, leaving out the hub, has worked. So it would appear that the hub was affected by the power cut/surge, although there was nothing to tell me that this was the case - all lights on, for instance, where cables were attached.
Thank you very much indeed for your patience and help.

Good work!
I'd continue to try all possibilities, like different ports in the hub, just to be sure.
Best wishes.
