Thanks for using macosx.com

I hope to be able to help you

Errr... thanks for the "somewhat lengthy" post..

OK my first question is have you opened the ports required? (unlike most other services the Mac doesn't seem to "just do" this one...)

This page seems to be the definitive text on iChat http://www.ralphjohnsuk.dsl.pipex.com/page3.html
what that man doesn't know about iChat seems to be not worth caring about...

But to summarise the page for you go to the firewall in Sharing Pane of System Prefs... create a new service and call it iChat or similar then follow this advice:

What to add to Change things for iChat AV

If you need to have your Mac's Firewall on, you will need to open the complete range of ports, as listed here:-
5060, 5190, 5297, 5298, 5353, 5678, 16384-16403 For just iChat Text, file sending and A/V chats (Can be copied and pasted into a "New" setting in the Firewall)

Please note the commas and spaces are important in the Mac Firewall.

This will probably fix it - it is the commonest cause of difficulty.

If not please come back to me and we will investigate more esoteric options

Hi Serenak
Tried that and still same error -21. It seems to try with video pane showing me and with the 'connecting' symbol but then throws up the communication fault.
I am using the appletest site and as I said before, with same settings, my home IMac is working fine. The MacBook shows the same fault on the home network and in several different Hotspot areas. Surfing the net, it seems error 21 is about the processor capacity so I offloaded my widgets and cleared cache to ensure maximum processor speed. Just running out of ideas!
regards Adrian

Hello Adrian

Rats - that was my best strategem - truth is I don't really know buckets about iChat, I rarely us it myself - though I learned how to get it running in most cases to teach a beginners' class at my local MUG...

http://www.ralphjohnsuk.dsl.pipex.com/page4a.html might help (or just rummage the whole site) - that man seems to have far too much time to spend on iChat

http://discussions.apple.com/thread....sageID=5250659
basically details the problem as you describe - it has some suggestions but no answer - you might find some thing you haven't already done...

Can you get AV over Skype or Yahoo Beta? or even aMSN? if you can then the fault is with iChat if you can't then you may need to investigate network or system issues...

I don't know that I can help you directly much more than that... if you wish I can throw the question back into the ring for another Tech to assist

ags - Sep 10, 2007 - 5:17 pm

Hi Serenak, Skype works well but is not quite as clear as Ichat when it works! Thanks for your help but it might provide another strategy if you throw the problem back in the ring. Many thanks anyway.
Regards Adrian

Serenak - Sep 10, 2007 - 6:24 pm

Yes I have noticed that iChat does have the benefit of far superior sound over most other options... I don't know how Apple do that but they sure do.

All I could find out since your last mail is that error 21 is "nominally" could not get service from camera... and appears to be more related to a bandwidth choke at the point of connection than the processor or RAM per se...

I would be inclined to point the finger at firewalls and NAT routers except you say the other Macs do not have a problem...

Sorry I couldn't help more Adrian...

I will throw the query back open as I send you this message.
