Accept incoming network connection?

For some reason, every time i open ichat now i receive this message:
Do you want the application "iChat.app" to accept incoming network connections?
Each time it happens, i choose allow, and it still does nothing to stop it
Anyone else getting this and know how to fix it?

MacBook, Mac OS X (10.5.1), 2.2 GHz Intel Core 2 Duo, 1GB Memory, 160 GB HD

Ralph, that worked like a charm for me - not just on iChat, but on all of the applications that had been throwing the "Accept incoming network connection? Really? You sure? How about this time?" dialog boxes. Thanks a bunch - I've linked to this thread from my blog (http://tinyurl.com/2s83h5), and added a few screen shots to walk people through it.

Thank you, what a useful post!

I had another problem entirely. The logic board on my MacBook Pro was replaced, and since I picked it up this afternoon, I was unable to connect to my Airport at home. I kept getting a self-assigned IP for my Airport connection. I would also get occasional prompts to allow incoming connections for mdnsresponder and configd.

Well, somehow I stumbled upon your post, and deleted all of the apps on my firewall list. Back in business! Now I'm connecting just fine. I still don't really understand why, but I'm glad I'm running again!

Hei Ralph

I tried your 'remove all and then re-add them' suggestion, as I am getting these messages ref. iChat, and Syncopation has a problem related to this. The former prevents iChat screen sharing, and the latter prevents syncing of iTunes Music.

I suspect Apple still has a problem with this firewall mode, and sincerely hope it will be fixed in 10.5.3..

So this http://www.sonzea.com/syncopation/index.html is supposed to sync iTunes across computers.

I am not sure how this effects iChat.

Are you saying these are the two problems you have on your Mac at the moment ?
I don't quite see how they are connected unless Syncopation is using some odd ports (possibly iChats) or is creating a VPN link (a subnet over ethernet or wireless) between the computers. This last could be an issue in iChat 4

Check System Preferences > Network and see if a VPN has bben Added and if in System Preferences > Sharing > Internet Sharing is On.

Yes, the iChat problem is quite frequent, I have just this instant reproduced it. It occurs when running screen sharing over iChat between iMac and Air. The Bonjour account is active, and iChat enabled at login on both machines.

On first attempt to screen share, the connection is not successful. My solution is to quit iChat on the iMac and reopen it. This immediately results in the message "Do you want the application "iChatAgent.app" to accept incoming network connections", which I 'allow' - screen sharing then works from either direction.

Syncopation is used less frequently as I don't buy from iTunes every day, but is similar in that syncopation.app is one of the allowed apps in the firewall setup (like iChatAgent.app), it is opened on both machines at login, and loses its ability to connect (like iChat). The solution when that occurs is to open all incoming connections, or remove/replace it in the 'set access for specific applications' table. The difference is that I can't remember being asked if I want to add the app to the firewall more than perhaps the first time.

I'm not saying Syncopation has any contact with iChat, just that its entry in the latter table doesn't guarantee connection, like iChatAgent.

It doesn't use VPN btw, and Internet sharing is not enabled. TCP connections to port 80 and 29000-29032 are currently allowed ref. Little Snitch, though I could probably remove 29000-29032 which were added when troubleshooting..

This does sound like two issues but from where I think the iChat one is it may be related.

Go to System Preferences > Security > Firewall and tell if it is set to Allow Specifics ?
If it it it should have a list of the Apps you have allowed.
This should include iChat and iChatAgent
(It seems that although you tell the system to allow it iChatAgent is not staying in the List).

Opps I see you have got to that part.

Ok this may be the issue that was caused by the 10.5 base Firewall settings.
Set it to Allow Specifics.
Remove everything from the List/
Set it to Allow All.
Make sure you have updated to 10.5.2. See below
Reset the Firewall to Allow Specifics.

If you are already at 10.5.2 and have NOT done the Time Machine and Airport v1 update then Rerun the 10.5.2 update via a direct Combo download

If you have done the Time Machine and Airport v1 Update then download the Combo and Pacifist
Open Pacifist (it will run as a trial)
Then open the combo .dmg
Drag the Brown/orange install .pkg to the Pacifist window
Use the Install option
(This Paragraph gets around an issue with the Time Machine and Airport v1 Update actually updating the OS past 10.5.2 But not changing the designation properly)

I hope this helps.

Wow, looks like the cure is worse than the pain 😉

I keep both systems religiously up to date, but I didn't know about Pacifist, so thank you very much for that tip! I used it to see if in fact the 'Time Machine and Airport V1 update' had been installed, and it had.

So I am downloading the Combo now, and will try the last section of your procedure. Many thanks for now. Will let you know if it helps.
