TICKET ARCHIVE -> screen sharing

tubajensen - Dec 30, 2007 - 7:32 am

My two Macs are in a network using a router connected via (ethernet) cable. Before upgrading from Tiger 10.4.10 to Leopard I used to be able to share screens between the two macs (a PowerBook G4 and an iMac G5). In Leopard I can view and connect from the PowerBook to the iMac but not in the opposite direction (from iMac to PowerBook) even though the PowerBook is "seen" by the G5 (under "Places" in the sidebar). The following warning is displayed when trying to connect from iMac to PowerBook:

Connection failed to “Allans PowerBook”.

Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer you're attempting to connect to. Also make sure your network connection is working properly.

Screen sharing IS enabled and the only network connection problem I have is the above mentioned.
Do you have any suggestions on how I can solve this problem?

Thanks,
Allan

Have you tried clicking on 'connect as' and re-entering your username and password details? This may do the trick for you.

cheers

Nothing happens when I try that. The "wheel" at the lower right of the window just keeps spinning. Finally I get a message: Connection failed.

OK, I'm not sure what your problem is. I'll re-open this ticket for someone else to have a look at.

Hi Allan,

I am wondering if any of the info on this page would be helpful to you:

Especially the part about "asking for permission" working where password would not? (Even though they say this doesn't apply to Leopard, may be worth a try.)

Hi Beverly,

and thanks for your suggestion. I had already looked at the above mentioned link before writing this help forum. Just went through all the methods again. Still, none work for me. Any other suggestions.

Hmm, have you tried repairing permissions on both computers? I think that's the next thing I'd do, and after that I'd run some utilities like OnyX (if that is out for Leopard?) and/or Applejack. After that if still no connection I would probably rename the powerbook and try making a new sharing connection. Let me know if you've done all these already or if any of these things help.

Tried repairing permissions on both machines. Applejack is not yet Leopard compatible:

I also tried renaming the PowerBook. Nothing seems to solve the problem. The weird thing is that I can see the change of PowerBooks name in the Finder on the iMac. I just can't connect or share screen.

Sorry none of that helped. I am out of ideas myself, and I will kick this back into the open question list in hopes another tech can help you.

First, lets see if PowerBook is really listening on port 5900. In terminal, run:

It should come back with something like:

If that is the case, you might try using a different VNC viewer, Chicken of a VNC and connect to the remote machine using display 0, and allowing the server to choose the number of colors to display.

Thanks Beverly and ScottW.

Just checked what was different on the two machines. As described I was able to share the iMac's screen onto my PowerBook but not the other way around. I know I should had checked this right away - anyway, looking at the System Preferences/Security/Firewall settings I found out that the PowerBook was set to "Allow only essential services" while the iMac setting allowed me to "Set access for specific services and applications". Even though screen sharing was listed under the "essential services" it apparently didn't work - since changing the setting to match the iMac's setting solved my problem.

Thanks,
Allan
