Making Client able to talk to other Clients

so my sorta IM program have 3 major components: Server, ServerClient, and Client. th Server listens for incoming connection thru ServerSocket, and when a Client connects, a ServerClient thread is started. thus the Server can talk to the Client and vice versa. my question is, how should I make one Client talk to other Clients? the ServerClient threads are not aware of each other.
Thanks!

You can have a Vector for keeping all ServerClient threads. You could write a method that would find if the user is logged in and another that would send a message to him. I think some sort of simple protocol will be needed for transfering what the user wants to do (send a message to the server, find if a user is logged in, send a message to the user, etc.) with proper parameters, but this is irrelevant for now.
Of course this is just a suggestion. Maybe someone will have a better idea.

Getting ichat to talk to other servers

So, we have a functional and running private server that we use to serve ichat among other things. It's great for talking to other employees who have server accounts via ichat.
But we can't seem to communicate with people OUTSIDE of that. It's getting to the point now where we would like to be able to chat with people outside of the company who also have jabber accounts (google talk, etc).
How is this done? It seems like it should be a pretty simple thing.
Thanks!

We have our firewall off, so my assumption is that the ports are all open?
Here is a bit of stuff from the ichat log when attempting to add a gmail buddy from our ichat client account:
Sep 10 12:47:18 server jabberd/resolver[70991]: [xmpp-server.tcp.gmail.com] resolved to 74.125.155.125:5269 (1800 seconds to live)

Apple TV and iTunes not able to see each other

I think I have found a bug in either iTunes or Apple TV. My network configuration is a bit complicated so I will describe it first.
Cable modem into my house hitting a Linksys WRT330N router at a central box in my laundry room. From there my house is hard wired to different rooms of the house. One goes to my office where I have a Apple Extreme N airport, connected to my PowerMac and my iTunes library. Again out of the central point in the laundry room again hard wired I have a wire going to my living room, where I have another Apple Extreme N airport, this is where my Apple TV is hard wired too. I have all the latest firmware and software installed on all my devices. Also both Airport Extreme's are setup using bridge mode and letting the Linksys serve the IP addresses for my network.
Now to the problem. I can not explain when or why but my Apple TV and iTunes are not able to see each other after about 48 hours. I have tried all kinds of troubleshooting steps including changing my connection from being hard wired to wireless connecting directly to the Airport Extreme my iTunes computer is connected too. I know my network connection is good as I can see trailers and pull up video's from uTube.
The only way to get them to see each other again is to do a factory reset of my Apple TV. After I do this they can both see each other again. But again after about 48 hours they lose the ability to see each other. I have taken these steps twice now to fix the problem
I just finished reseting my Apple TV and am going to watch it to see when it stops working the next time.
All of these problems started the other day when I introduced a new Apple Extreme N router in my my network. The airport Extreme seem to be working fine with my PS3 and XBox 360 that is also connected to it. So I don't think it's the router that is causing the problem.
If I had to guess I would say something in the Apple TV is locking up. Although I have tried power cycling the Apple TV which does not fix the problem. I'm going through 3 routers to get between the Apple TV and the iTunes library somehow it appears the Apple TV is losing it way.
I welcome any help as I don't want to have to keep factory resetting my Apple TV to keep it working.

Fascinating just reading about your setup. I have a WRT350N and have noticed that it will drop its speed, sometimes down to 1Mbps. It seems to do so at about the same time every day, but usually comes back to speed in about 5 minutes. In my experience, the Apple TV will disconnect if the speed falls this low. Try monitoring the Linksys with Netstumbler, Vistumbler, or just in the Windows Network utility.
Check the "lease obtained" and "lease expired" times for your router to see if that is when the network fails. I've just finished reading an angry thread over at the Linksys forum about the WRT330N where someone mentioned that the router wasn't renewing its lease.
"I cannot set it run off automatic DHCP from the WRT330N, the router will not assign it an IP every time the lease expires, causing me to have to manually set an IP on the Print server. That's annoying. Having the router drop IP's to individual machines after 12-48 hours...very annoying."

If that is the problem, then I would consider setting up a Static IP address for your Apple TV. You can do that through the user interface -> Settings -> Network -> Configure ... (Quite intuitive as you only have change IP address and the subsequent details remain the same.)
My router assigns IP Addresses in the ranges of 192.168.1.100 ->149. The idea here is to choose an address outside of that range but is not greater than 192.168.1.253 (and should not end in the number 1). You shouldn't have to change the linksys router as long as 50 clients are assigned in that range. You'll have to figure that out by accessing your router webpage at browser address 192.168.1.1 -> the default password is "admin" (without the quotes).
Good luck.

Making Calls with Broadband Talk

Hi Guys,
I was just wondering if someone could clear this up for me??
When making calls using Broadband Talk, do you have to dial the entire number (incl. STD Code) or should you just be able to make the call without this?
For example, I live in Derry, N.Ireland and the full number starts 02871. When dialling from a normal landline you would just dial "71" and the the rest of the number. However. if I do this using my BB Talk line, I get a Dead tone. I tried to make a call and entered the number with the full STD Code, puely on the off-chance it would work, and it did actually work!! Is this necessary or should I be able to make a call without the full STD Code??
Cheers
Solved!
Go to Solution.

I think you always have to enter the dialling code I'm afraid

Will we be able to talk and surf with the iPhone 6?

Does anyone know if we will finally be able to talk and use the web etc on the iPhone 6?

The devices also include support for Voice over LTE (VoLTE) which allows users to make higher-quality phone calls over LTE. VoLTE will also allow users on CDMA networks like Verizon to use voice and data simultaneously for the first time.

You will need to try changing the email address on the first account and see if you can then re-use it on a new account - you can try changing the email address via http://appleid.apple.com or by logging into it via the Store > View Account menu option on a computer's iTunes (if you don't have a spare email account then you can create one via http://gmail.com or http://hotmail.com)

I am able to connect to my wifi network but am not able to connect to other computers on my network

I am able to connect to my wifi network but am not able to connect to other computers on my network. I have installed windows 7 on parallels desktop, from windows i am able to access my network computers. But from Mac i can only access internet but not network computers Please help

Ok, well if you're sure that there are shared folders on your PC's, then try this:
Click somewhere on desktop, so you're in finder > Go > Connect to Server (shortcut to all of this is Command + K) then type in: smb://ipaddresshere
eg:
smb://192.168.1.7
Then either connect as guest, or login with the PC's (not your mac's) username & password.

If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.
