IChat4 each client can video chat with test accounts but not each other

I have two machines with iChat4. Each machine can video chat with the apple test accounts but the dreaded error 8 when trying to chat with each other.
Any Ideas?
Thanks
Dan

Ok,
In the Netopia turn the Firewall to Off as the settings LOw and above have some of the features I was talking about (DOS and SPI protection and Ping Blocking.)
For the TZ-180 I can only find info on the TZ -170
This site tells you how to do Port Forwarding.
The main point off linking you to it is it also tells you the default Access Info.
It is likely to be the same for this device your Buddy has.
I would not do the Port Forwarding straight away.
I would check the menu items to see if it has UPnP and that it is Enabled rather than Port Forwarding.
I would also check for the features or the wording of any firewall before resorting to setting the Port Forwarding.
I notice that the TZ-1 70 pics that site has also shows that that particular device has a VoIP setting.
IF the 180 has this we will need to know what it says and what the wording is and if the service is used.

I can video chat with my Dad, but he cannot share his screen

My mac:
Lion, 10.7.4 My iChat: 6.0.2
My Dads mac:
Snow Leopard, 10.6.8, his iChat: 5.0.3
We are both signed in using our .mac acounts.
I dont know what has happened, but right now we can only Video chat with each other.
I am able to invite him to see my screen, but he is unable to invite me to see his screen.
This is a major problem, becuase seeing his screen is the main way I help him get out of trouble on his computer.
I am not sure what caused this - it used to work great.
Not sure if it has something to do with the shut down of MobileMe?
Or if it occurred when I upgraded to Lion?
Is there a fix for this?
Or should I upgrade my Dad's mac to Lion?
THANKS!

HI,
This will work between iChat versions that support Screen Sharing.
At both ends check the Video menu and the Screen Sharing option.
This has to be On in some cases.
A sort of Half-way House setting can be achieved.
If it is Off then you tend to be able to call Out - effectively offer your Screen as calling out is not effected by this setting, nor does the Mac firewall get involved (once you have punch an outward port it tends to allow incoming responses.)
The Screen Sharing works in four scenarios:-
You Offering your Screen
You Asking to view the Buddy's
The Buddy Offering their own screen
The Buddy asking to see your's
In your post you only list two of these.
It will pay to check the others.
It may have "happened" when upgrading to Lion and iChat 6.x.x as some settings can get set back to Defaults on occasions for some reason.

Why can I chat with a buddy but not add them to my Buddy list?

I'm using iChat 4.0.2 with OS 10.5.2.
I add a particular buddy to my list but the name fades in and out and then disappears all together in a few seconds. No matter how many times and ways I try, I cannot add them to my buddy list and get them to stay. I can add other buddies to my list normally.
During the time I can see this particular buddy's name in my buddy list, if I'm quick enough before they fade out, I can click to connect and chat perfectly. I can also request to view video with them and have them accept and view normally. However, if this buddy sends a video request to me, I hear the ring but then an instantaneous message window appears saying that the buddy "cancelled the invitation".
Interestingly, after connecting with this particular buddy, I can maintain their text chat window and text chat as normal. This buddy is using iChat 3.1.9 and OS 10.4.11.
Any help or ideas with how to keep this buddy in my list would be appreciated.

Interesting.
I would have gone the iChat > Preferences > Accounts > Security and just checked the Block list first.
com.apple.ichat.Subnet holds the sort order and Allow/Block lists
Setting the Preference to Allow All and then checking the Allow option and possibly the Block list would change the Subnet.plist anyway.
For some the Flashing/disappearing Buddy is a result of iChat 4's response to Feedbag Error 10
Feedbag errors are AIM codes for problems with the Buddy List.
In this case it is adding a Screen name with a Real name option and that Real Name is already in the Address Book.
To restate.
I would leave the deletion of com.apple.ichat.Subnet.plist (as this will remove all those that may be in your Block list) until all other options have been exhausted.

Two computers who can video chat with everyone but each other

I don't get it, I can video chat with the apple test sites and anyone else who has left me their name on this site. My realtive in Seattle can do the same. But we can't video with each other. However, when I disconnect my cable modem and plug in my high speed wireless modem card, we connect. I have made all the setting changes to my Lyksys modem suggested on this forum with no success. Is it possible that her cable modem and mine are incompatible and just won't talk to each other? (we can text each other, just no video or voice)

Have a look at this section on my Web page
http://www.ralphjohnsuk.dsl.pipex.com/page15.html#CertainBuddy
It suggest the steps Rj is talking about.

Can video chat with everyone but 1 person

My father and I both have iSights, yet for some reason we cannot connect to each other to video chat. However, both of us have successfully connected to other people for video chats, so I am completely confused. I am connecting wirelessly via a Netgear WTG624 v2 router, and my father is using an RCA broadband wireless router/modem model #DCN725. He has both a 700MHz G4 iMac and a 1.2Ghz G4 iBook. Neither machine can successfully connect to mine. All machines are running Tiger with the latest version of iChat. What happens when we try to connect is the other person will receive the invite, accept, and then it will say Starting connection with... and then it will say connection cancelled cause <whoever initiated the session> failed to respond. Any ideas on why this could be happening? thanks so much!

I have had exactly the same problem - both of us could connect to the Apple test accounts, but not to each other. We do now have a working connection though. I'm not sure this is the solution for sure, but when I was running iChat in debug mode, I could see that it thought I had multiple IP addresses. Because I run Little Snitch, I can see the outbound connection attempts being made, and when the connection didn't work, it was because it was trying to connect to a "private" IP address configured on the other person's computer, rather than their public IP address.
What I did was each of us went into System Preferences, Network, and for the Show: dropdown menu at the top selected Network Port Configurations. We then unchecked every network port except for the one we were using for our internet connections. This included disabling extra ports that were there for programs such as Parallels, whose IP address my iChat was trying to connect to.
We then both quit iChat, and restarted, and we could communicate.
I don't know if this is the answer for everyone, but my theory is that if you have more than one network port configured with an IP address, iChat gets confused as to which one it needs to map through the firewall.
Let me know how you get on.

Video chat works to one person, not to other

I am on the road w/my iBook G4. I have no trouble establishing a video chat with one person, but can't get it to work when I try to connect to my home machine. My home machine can do a video chat to someone else. it gives me a failed to connect, or the person declined the invitation message. any help?

Hi David,
These are User to User help forums.
There a limited number of Hosts who monitor the content for offensive and posts against the Term and Conditions.
There is some evidence that some information is taken from the forums and made into Knowledge Docs, but it is rare.
From the iChat menu there is a link to the iChat Feedback page and 10.4.7 now includes a log creation that you can send to Apple on certian types of connection failure.
As different modems and routers do actually use different forms of NAT (Network Address Translation) used when people use Port Forwarding, Triggering or DMZ then there can be problems with connection when the devices don't "Play Nicely".
We would ned to know more about the devices involved to comment further

Video chat works on AIM but not iChat

I'm trying to do a video chat with my dad who is running AIM 5.9. I can not create a video chat with him using iChat regardless of who initiates the chat. However, I can video chat with him when I fire up AIM 5.9 on my PC.
I think things are set up correctly on my side. I had been unable to video chat with rjinwipc, but got that working after updating the firmware on my DI-624 router.
Does the fact that AIM works but iChat does not say anything about where to concentrate for troubleshooting?
Mac Mini Mac OS X (10.4.5)

Umm,
I see a potential problem.
The D-Link DI 624 does not like doing UPnP for iChat
See note 2 here (This may have been corrected with later firmware that shwn in the table of devices).
This is of Course to get these listed device to Work Out of the box rather than set up as many people have to do.
Moving back to the problem We have a device that does not like UPnP and another computer to connect.
If Port Forwading is being used then one computer is out of the loop anyway.
Potential solution is to Port Trigger. Which PortForward.com shows as possible.
I would not use this method described on this page though. as it descibes a PC app to help with a Mac application.
Set the iChat ports like this.
Trigger port 5190 (Start and End) TCP protocol (Type) to open Port 5190 Public tpye Both
Trigger port 5678 (Start and end) Tpye UDP opens ports 5678,5060,16384-16403 (please not the lack of spaces)
The Bonjour ports need to be triggered as single ports like 5190 but the public type for 5297 and 5353 can stay at UDP and the 5298 can be set to Both.
The Jabber ports of 5220, 5222 and 5223 can also be set as single triggers.
The AIM application will then be able to use the Port 5190 trigger.
It will also need ports 1024-5000 to be triggered with port 1024 as the trigger (On TCP)

In ical I just added new calendars to a pre-existing calendar group, I can make events with these calendars, but not reminders, any suggestions?

Hi,
Lion has changed the way reminders (todos as was) work. They now seem to need to be in a seperate calendar.
In iCal open the File menu and select New Reminder List... and select where to put it.

You can't connect directly to the external drive, but should be able to use iTunes Home Sharing via the laptop.

Oh no! I'm sorry to hear you had problems in the are you're in AkJohnDye. I checked your coverage and I do see we have an extended 4G coverage. This means you're able to use your phone but it needs to be activated in a 4G LTE Verizon Wireless coverage zone. I apologize.

IMovie works in Test account but not in main user account

I have been having issues with iMovie such as lag time and trailers not playing back properly in preview mode. I created a new user account to see if it was isolated to my own user and sure enough the problems went away and iMovie is working smoothly.
So what could be causing the issue on my user account? I tried to usual suspects: repair permissions, delete preferences, etc., but nothing helped.
Any ideas?
Thanks,
Stephen

Wondering if anyone has any thoughts on this issue? I can't figure out why it would work on a test account but not on my main account.
Thanks!

How can i delete my icloud account but not the password to turn off the find my phone

how can i delete my icloud account but not the password to turn off the find my phone setting

Make sure you are signed into iMessage and FaceTime with your current ID. If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.) Now go to Settings>iCloud, turn off Find My iPad and enter your current password when prompted (even though it prompts you for the password for your old ID). Then save any photo stream photos that you wish to keep to your camera roll (unless using iCloud Photo Library). When finished go to Settings>iCloud, tap Sign Out and choose Delete from My iPad when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your device).

When i add an entry to my ipad calendar it syncs with my iphone but not the other way round. Icloud is turned on on both.

Can video chat with Aim users on a PC but not with Ichat users on Mac!

Hello
I am having the odd problem of being able to video chat with someone when they are using their pc running aim, but I cant chat with the same person when he on his Mac!
I am running as DMZ behind a Linksys WRT54G wireless router.
The problem is on my side because I cant chat with the test accounts either.
I tried this after bothe forwarding and triggering all the ports that were suggested.
I am stumped!

Hi Lullah,
This is going to be down to the Staelite connection.
It has what is called latency.
This adds an unexceptable delay in the passing of data at the start of the connection.
Very few people have reported success.
The things you can try are to fool the link into passing more intense data prior to starting a chat.
If you have web pages try uploading a Pic of larger file to the site.
Just as this finishes start up iChat
You should also check that System Preferences > Quicktime > Streaming tab has the speed to match you download set.
Hopefully (But no reported success) you may get iChat to see more bandwidth as you have just had the modem busy.
Following the launch of iChat with a video chat request may be able to get that bandwidth.
Realistically the 128 k upload even if you were getting close to it is very tight to the lowest point Apple say will work.
Speed testing a 128 k service i likely to get a result of about 80% of the figure (102k) iChat will use about 80 % of what is left (you are down to about 83K). You are now below the 100k min.
With regards to your LAN there are several things that may help if not set up already.
Only have one device doing DHCP. The way routers work as compared to modems is that they pass all routing data though to the computers.
This means the computers can be sitting in two subnets (1) from Modem to computer via router and (2) from Router. The computer can only display one of these IP addresses but can get confuse info regarding iChat.
Do not use Port Forwarding or Port triggering, twice or together on the LAN. iCHAT does not like two lots of NAT (bath are forms of Network Address Translation [NAT]).
Use UPnP where you can.
IF you are trying to test this yur Mac to your PC you ahve to allow for the fact that the modem is handling two Video chats in effect. This means you need twice the minimum bandwidth (let alone the fact that ichat to AIM semms to like 50% more than Mac to Mac contacts.
Sorry to be the bearer of so much doom and gloom.

I can video chat with John, John with Mike, but not Mike with me?

My brother lives in Abu Dhabi and he and I can video chat. He can also video chat with my dad (Mike) who lives about 500 yards from me (in North London). But I can't video chat with my dad, nor can we audio chat!
We've both attempted to initiate the chat and get the error code "-8", upon clicking 'accept' the other party gets a message that the invite has been refused.
Can anyone offer any suggestions as to how I can go about getting this resolved? I'd like to get to the stage when all three of us can video chat at once.
Thanks for any advice.

Hi
First have you all set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps
In ichats prefs click on video and change bandwidth limit to none.
Restart iChat.
And also try logging on to AIM on port 443 rather than port 5190.
Go to IChat in the menu bar > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.
Log back in again.
Tony
