Why is a hub needed for ichat a/v locally?

If I'm not mistaken it's currently not possible to create a network by having all nodes except one join the other using adhoc networks and for that machine to act as a router. Why is this the case?
Why do I need a router to do ichat a/v b/w computers locally?
Back in the days a machine could emulate a basestation correct?

Hi Robert,
I have two Macs but they are through a Routing modem.
I also run Little Snitch on one of them and have not seen iChat call SNATMAP when using Bonjour.
I have the modem set to use UPnP. The Mac Firewall is not on but does list the Bonjour ports (along with AV and Jabber).
The Bonjour ports are 5298 on TCP and 5297, 5298, 5353 on UDP
It is the 5353 that most people miss as it is not one of the Bonjour /iChat presets in the Mac Firewall.
I do have my DNS servers fro my ISP listed on both the modem and my computers.

Why are ports 36000-36999 needed for iChat AV

I have a homegrown firewall on my network that allows me to do whatever I wish.
When testing this with a ichat AV 4 user, I had to open the following ports to make it work:
${fwcmd} add pass udp from any to any 36000-36999
${fwcmd} add pass udp from any 36000-36999 to any
Once that was done, the video/audio worked fine. I had already punched the other recommended holes:
${fwcmd} add pass tcp from any 5190 to any 1024-65535
${fwcmd} add pass tcp from any 5298 to any 1024-65535
${fwcmd} add pass tcp from any 1024-65535 to any 5190
${fwcmd} add pass tcp from any 1024-65535 to any 5298
${fwcmd} add pass udp from any 5060-5061 to any 1024-65535
${fwcmd} add pass udp from any 5190 to any 1024-65535
${fwcmd} add pass udp from any 5297-5298 to any 1024-65535
${fwcmd} add pass udp from any 5353 to any 1024-65535
${fwcmd} add pass udp from any 5678 to any 1024-65535
${fwcmd} add pass udp from any 16384-16403 to any 1024-65535
Why were the 36000 ports needed?
Also, when testing with an iChat 3 user, I couldn't initiate the call, but they could and it worked...
One more thing I should add is that I tested the ichat4 to the appleu3test02 aim user and it worked without punching the 36000 holes.
Any clues would be very helpful.
Thanks,
Micky

Ok,
I will tell you which ports iChat 4 uses.
You can then decide how to enter them into your set up.
5190 on TCP for AIM Login. An alternative we suggest is 443
This can be SSL on either port for iChat 4
5190 on UDP for File Sending, Pic in Text chats (Direct chats) and Group chats.
5222 and or 5223 on TCP for Jabber login depending on your Server
5220 for Jabber on TCP (rest of their port use)
5297, 5298, 5353 on UDP for Bonjour
5298 on TCP for Bonjour
5678 on UDP for sending and receiving Visible part of A/V invite
Ports 16393-16402 on UDP for the SIP connection phase with the SNATMAP server AND the A/V chat it self. Use one port at a time for all of this (Different from iChat 3) Starts at port 16402 and move down one port at a time for those 10 ports then tries random port.
5900 TCP for Screen Sharing (Unsecure connections) VNC.
See this Doc for some info
http://docs.info.apple.com/article.html?artnum=93208
This for some of the iChat 4 Changes
http://docs.info.apple.com/article.html?artnum=306688
This for the VNC bit and confirmation on Port Use and the use of Jabber on some server 5553 in Note 10
http://docs.info.apple.com/article.html?artnum=106439
What happens sometimes is that if the other end is doing Port Forwarding, DMZ or Port Triggering with NAT happening in two or more devices then the ports get changed.
You see this is some Error 8 logs. This in fact itself goes back to info that appeared in the Error log drop down in iChat 2 (And 3 before 10.4.7) that gave you some of the info about how the call was progressing when it failed.
Doing NAT behind tow or more routing devices can be the problem. It is even worse when people have two DHCP server further complicating the issue.
I am not sure why you have not pointed them port for port.
(I know the Apple Doc does says in it's table that this is an option.)
Most domestic devices via a web browser set up, work fine pointing 5190 at 5190 for example. iChat data is then expected on an iChat port and pointed to an iChat port on your computer.
Realistically a firewall should work the same way.

Why there's no Need for Speed game in the apple store?

Items needed for iChat Av

i am wanting to set up an iChat between my mother and i (she lives 4 hours away)
i know that i need the iSights, but in regards to software and accounts, what do i need??
i have looked for FAQ on iChat AV but can't find any help.
it is recommended that you have a .mac account, but is this necessary and if so would i need two (one for her and one for me)
please advise

Hello, Ryan.
I'm butting into your conversation with (lab specialist and others) because I am searching all over trying to resolve my own problem. This thread looked close. But it's not quite my answer. You seem very knowledgable on this so...
I have AIM for mac 4.7 and iChat AV 2.1. I'm in OS 10.3.9.
iChat won't acknowledge the very same people that AIM does. I have a buddy (actually this happens with more than one buddy) listed in AIM whom I communicate with fine. Her same name is in my iChat buddy list but it tells me she is offline (while I am chatting with her in AIM). She, by the way, has iChat 3. using Tiger. I try to add a buddy in iChat but by default all I can select is AIM or .Mac - or her email from my address book. I presently have her as all three but still cannot connect. She says she does not pay for a .Mac account (but I now understand after reading your info that she probably did sign up free and it allows her to continue with IM only). Her screen name in my AIM has no @.... anything. Just a name and number she chose. When I try to enter that in iChat, of course, it adds a @.mac on the address book entry, and aim on the one I tried adding as Other. Neither work!? But she's coming in loud and clear in my AIM. Can you unravel this?
ps, I did create a new post in the iChat 2.1 forum pretty much asking the same question but it may go unnoticed.
Thanks.

What we need for ichat 3.....

Apple customers have been waiting since tiger's debut and i think that these threads says it all:
http://discussions.apple.com/message.jspa?messageID=1339241#1339241
http://discussions.apple.com/message.jspa?messageID=1339195#1339195
i think we paid money for this now "non-working" package and a very pricey camera. We have waited and waited, without a word from apple on this issue.
I have repaired and tested my isight, with the help of Ralph's efforts and the test sites, but still can't video connect to anyone, except testers on the boards.
There have been messages sent to apple, via their feedback form. ............................................................................... ..silence....................................................................... .
Now what?
What would be great is: We need a crafty person to make ichat 2.1 work on tiger. some sort of a patch, that will trick tiger into thinking that ichat 2.1 is able to run.
who knows if that's possible. By suggesting this, I am sure they will dump this post in a few minutes.
does anyone else feel the same?
If there is any input from apple, I would love to hear it.
posted in desperation.... paul

Ryan,
I hear you and appreciate that you have already tried getting 2.1 to work on tiger.
Aside from the fact that we paid for tiger and should be able to use it, I don't think downgrading is going to solve the problem. Unless everyone does it.
Beleive me, PLEASE, when I say that i have been though all of your suggestions and I have managed to get my side of the connection working. The problem lies in the fact that now everyone else needs to do the same, which isn't going to happen.
I haven't given up, i just think that short of troubleshooting one connection, with one person, there isn't a way to fix this problem.
Do you think that it is realistic to hop on the phone and walk someone through fixing their connection, every time you want to initiate a video chat with someone new?
Lastly, my hope with this thread was to provide a place for users to post their thoughts, without clogging up your troubleshooting forums. Seemed reasonable to me, given the fact that there is no way to voice your frustration, with this situation. Sending emails to apple doesn't help. At least, we know that someone from apple is seeing these threads....
thanks for you help ralph

Why is IP address needed for WLC WLANs?

I'm familiar with autonomous APs but am new to the WLC. Is there a way to just bridge the WLAN traffic to a VLAN? I don't understand why the WLC requires an IP address for the VLAN when the clients essentially are already on that VLAN. How is it used?
Thanks.
(Edit: fixed typo.)

the parameters specific to this VLAN. Some of the parameters include the IP Address, Netmask, Gateway, and the DHCP server IP address.
The IP address assigned to this interface acts as the DHCP relay for a client to obtain an IP address from the DHCP server. For example, when a client attempts to associate to a WLAN/SSID (see step 5 in this configuration) mapped to this dynamic interface, it performs a local subnet broadcast to identify the DHCP server. The controller sends a request to the DHCP server (or to itself if it is the DHCP server for the segment) with the IP address of this dynamic interface as relay IP to the DHCP server configured for this interface. The DHCP server assigns an IP address to the client from the configured DHCP scope.

Why EAI(XI) is needed

Dear all;
i have one question regarding why XI or EAI has to be used against direct development, is fundamental question, but very important..
As far as i know, advantage is below;
1. make stadard pattern to build development easily.
2. central management, centeral monitoring.
i would like to know why EAI(XI) is needed for technical key point except for above advantage ?
please do not mention SOA, BPM and SAP XI Contents, just look inside technical key point.
thank you in advance
Dennis

hi ogawa,
This link would give you more information

I know my Apple Id (not .mac) and password but I can't logon to ichat. I keep getting a message of password not matched. Do I need to create a new account for Ichat?

I know my Apple Id (it isn't ".mac") and password but I can't log on to ichat. I keep getting a message of password not matched. I saw somewhere that my Apple id is the same as my ichat account. Do I need to create a new account for Ichat? I've already reset my Apple id password 3 times in the last 2 days. What am I doing wrong?

Hi,
At one time only Email IDs from Apple (when it was just @Mac.com) were referred to as "Apple IDs"
Other IDs such as to log in to Discussions were know as Discussion IDs
Things like the Online Store and iTunes and Apple realising that people would prefer one ID to have access to Everything tended to move things together.
There can be a variety of combos now
iChat Name
@mac.com before MobileMe
@mac.com post MobileMe
AIM Names
AIM names current
MobileMe (@Me.com)
Style
Email Address valid with the .Mac service prior MobileMe Note 1
Email style Name Valid with AIM
May or may not be an Email address
Can be AIM issued or third party Email address
Valid Email with MobileMe Service
Other Abilities
May also be Currently valid email linked to a MobileMe account
Maybe Valid Apple ID
Is a Valid AIM Screen Name
May Not be a Valid Apple ID (was an option choice at one stage)
Is a Valid AIM Screen Name
May not look like an Email (No @whatever.com) but may be linked to either an AOL email account or AIM one
Current Registration seems to be pushing Email registration (@AIM.com)or asking to use another you currently use.
Trial Accounts are limited to the Trial Period Only as Emails, Valid AIM Screen Names and Apple IDs.
Apple ID
Possibly (likely)
Possibly (depends when Registered)
More currently Yes.
No
No
Yes
Glad I could help.

Why we do not need sender agreement for Mail and SOAP adapter

Hi SDN,
I know, we do not need sender agreement for IDOC ,HTTP,XI adapters. As these three adapters will run in Integration engine of the abap stack.
In our scenario if sender is other than IDOC or HTTP or XI .
By Refering Sivamni's blog.
/people/siva.maranani/blog/2005/05/25/understanding-message-flow-in-xi
message will be pickedup by communication channel with the help of sender agreement and prepare XI message header by performing cpa cache lookup. then message will go to module processor etc.
In our scenario if sender is IDOC or HTTP or XI .
As these 3 adapters are run in Integration engine.
Doubt 1:
how the integration engine will create the xi message header like sender interface sender system name etc...
Doubt 2:
I believe SOAP and mail adapter will run in adapter engine.but i came to know that we do not need sender agreement and sender comm channel for these two adapters too...then how the XI message header will create...
Please do correct me if i am wrong
and throw some light on the same..
Appreciate your help....
Regards,
Reehan.

Reehan,
Thanks for pointing me to that link. Guess I was wrong .,But,let me try to put to you why you need a sender agreement for a Sender SOAP Adapter,
1. In the sender SOAP adapter , the Sender Interface and the Interface Namespace as provided in the fields Default Interface Name and InterfaceNamespace. The Name of the Sender Service is provided in the WSDL when you ceate the WSDL in the Integration Directory. So, as all details are available in either the Sender SOAP adapter or in the WSDL url you do not need a Sender Agreement. It is not obligatory but you can always create the Sender Agreement.
2. For the mail adapter , if you select the option XIPAYLOAD, you will have the option to mention the Interface Name and Interface Namespace under XI Parameters and so in this case as once again the details provided in the sender agreement are available in the Sender Adapter itself the sender agreement is not needed for the mail adapter when you have select option XIPAYLOAD.
If you have selected XIALL then you need a sender agreement.

Bhavesh

What is needed for a PC user to video chat with me on ichat?

I'm a newbie at this....The easiest solution is to convert them to MAC! But that isn't going to happen! Desperately need to see my little grandson.....please help if you can.....the answer is probably very simple and i am going to feel a little silly.
My husband and I communicate just fine on video ichat between our two MACS....he uses an @aol.com id and i use a @me.com id

Hi,
AIM for a PC or the app Trillian will do it (With an AIM name).
Trillian used to sell 3 versions until recently. The oldest, ver 3.2, now seems to have disappeared from their site. It was on "Sale" at $15
They also seem to have renumbered the various releases as Version 3.2 used to be the same for Mac and PCs
The previous layout also implied the Mac version was the same as the Windows 4.2 version And the Beta option for version 5 has also disappeared.
Also if you have a Google mail Account and they do as well you cna both turn On the Talk option at Google and make use of GoogleTalk in a web Broswer.
iChat can make use of the GoogleTalk ID (It's your email in fact) and you can Video Chat to other iChat Users that Google or Jabber IDs (GoogleTalk is a Jabber server).
It will not however Video chat to the Standalone PC app of the same name or to anyone using the Chat feature in the Google Mail Web page (Different Protocols)
You can use other web sites to do Browser to Browser Video chats
See the options 9 through 11 (12 is now defunct) and MeBeam is now called Koowy.
These options need Flash to be enabled in your Browsers (both ends) and it will give you a Pop up to Click Allow for access to the Camera (Which you may also need to chose in one of the tabs)
I may receive some form of compensation, financial or otherwise, from my recommendation or link.

Why did AIM for Ichat suddenly return an error?

I was using AIM for iChat earlier this morning and everything was working fine. Then suddenly, without warning, it logs out of every iChat account and returns the error: "An internal error occured that disconnected you from all iChat services. To resume iChat, log in again to your instant messaging account." I can log into my bonjour and jabber account, but as soon as I try to connect to AIM, it brings them all offline. I went to AIM.com and signed in and have been using the web client since, but apparently this has happened to about half of my friends on iChat. Why would this be and what can I do to fix it?

Hi,
Now and then the AIM Servers have a blip and many people seems to get kicked Off Line.
I have server accounts/AIM IDs and keep some using SSL and the api.oscar.aol.com server on port 443 and some using the login.oscar.aol.com server on port 5190 without SSL.
Usually it only effects one group of my logins and not all of them.
It can of course be a server local to you that is having issues.
