TCP ports open or used?
I am running windows 98SE and trying to use PC to PC calling in Yahoo
messenger 8. As soon as I try to accept a call from someone running XP with a firewall Yahoo messenger crashes. I crash but not the other person. I went to yahoo messenger help and I quotethem: What ports are used by Yahoo! Voice services? Yahoo! Messenger will work if any one of these TCP ports are open: 5061 443 80 At least ONE of these ports must be open in order to make PC-to-PC or PC-to-phone (Phone Out) calls, or to receive calls (Phone In). Where on do I find if theses ports are open and how could I open one if I need to? |

I don't think it's a ports issue. Port 80 is what internet browsers usually
use, and yours works OK, right? In any case, you "open ports" in whatever firewall you're using, either on your machine or on a router you might have. Exactly how depends on the make/model of the firewall(s). Have you tried reinstalling Yahoo! Messenger? Uninstalling first would be a good additional procedure. -- Gary S.

Gary I will try the un and then reinstall or Yahoo messenger but for
future reference where do I see the ports and what is using them? And do I need to be online and with IE browser open and in use? Also are you also saying that the person I want to voice chat with is the one who needs to configure their firewall. I assume they are using the firewall that comes with XP??

TCP ports open or used?
First, I'm not *real* familiar with these issues. This is a Windows 98
group, and not even the one I'd recommend for these issues. Your issues have a lot more to do with network protocols than with "Setup". Personally, I think you'd have better luck trying to find a Yahoo! forum that deals with YM voice communications and how to properly set up the computers that are using it (firewall settings, for instance, or possible YM port settings that will make things work better.) There are two major issues with ports. One is that the applications that are communicating with each other have to be using the same ports. If my email client is trying to communicate with an SMTP server (outbound email) using port 25, but the server is only listening to port 2525, the communication will fail. If your colleague is trying to send you messages on YM using a port that your YM isn't set to receive on, the communication fails. If your YM is sending to a port on the other machine that that machine's firewall is blocking, the communication will fail. Firewalls are intended to block communications on all ports except those which are explicitly opened. Typically, the port is opened only for use by certain application or applications, and/or only for certain protocols (like HTTP, HTTPS, SMTP, POP, FTP, etc.) But you use the word "crash" to describe your issue. Is YM really "crashing"? Or is there just an error? Is the result that YM just disappears and you have to restart it, or is there a general failure message causing you to forcefully kill YM (using Ctrl-Alt-Del, for instance) and restart it? Or are you simply getting a message that the communication can't be done? You need to be online to communicate, obviously. That is, your computer needs to be connected to the internet. But that does not equate to having IE or any other browser open. IE does not connect you to the internet, it is just a way to communicate with web servers once you've already got internet connection. Port 80 is the one most used for HTTP communications. If you can browse the web using IE, then the firewall isn't probably blocking port 80 for HTTP communications... But it might be blocking the use of port 80 for any other purpose. My guess is that the XP machine's firewall isn't properly set up to allow the use of YM on *that* machine, for the ports *your* YM is set to use. But why that would cause a crash is something I can't answer, and that's why I suggested that you reinstall your YM, to see if it will then properly handle whatever the other YM is sending (or handle the failure to communicate more gracefully, perhaps even producing an error message containing usable information, like what port(s) the incoming communication is trying to access.) I know I haven't actually answered your question(s) precisely, nor have I really addressed the specific problem you're having. But perhaps this will give you a slightly better understanding of what's going on and where you might look for whatever it is that is causing the problem(s). -- Gary S.

TCP ports open or used?
Gary,
I have gone to YM's forums with little suggestions in getting an answer. In the voice section of the forums not many people are communicating and not much usable information is given. When I say I crash I do indeed crash my system Win 98se stays working but YM just suddenly quits. It goes away fast without any error message as soon as I try to accept a call from the other person or they accept my voice call. I then can just go and restart YM and re-send a text IM and send and accept to see our web cams again. I guess I could be using IE 6 at the time but do not have it running to avoid bogging down my older computer. Would it maybe help top have it running for I am not sure if I ever had it running while trying to communicate via PC to PC calling. The strange thing is our web cams work fine and we are able to talk to one another via voice if we are in the same chat room but then our conversation is far from private. Can you tell me where the XP user would see if the firewall is allowing port 80 use or is that a given if we can IM using our keyboards? Gary S.

TCP ports open or used?
It's a given that port 80 is open on both machines for HTTP, but I don't
think that's any part of the problem. I only introduced IE into this conversation as a way to explain that this was almost certainly true. Forget about IE. Can you clarify this one point for me? Does the problem *only* happen when the XP machine's firewall is turned on? Does the whole setup otherwise work just fine with XP's firewall turned off at the other end? If so, this would suggest to me that the firewall is blocking *some* of the ports that the YM on that machine would prefer to use, say all but 80, forcing it to use port 80, which, when it gets to you, your YM doesn't like. The trick would be to add YM specifically to the exceptions on the XP firewall, with all of the ports you listed previously "opened". Looking at my own XP system (well, not really my own, it's one I'm borrowing -- I don't personally use YM), it has YM installed, with YM and YM FT Server (financial ticker), and both have been added to the firewall exception list. I'm wondering if the service you're trying to use also needs to be added to the XP firewall exception list. I would assume that the YM installation on that system would have automatically taken care of that, and the opening of the required ports, too, so perhaps reinstalling YM on that machine is the answer. But it's simple to add ports to the XP firewall exception list, manually, so I'd try that first. But, the above only applies if the setup works fine when the XP firewall isn't enabled. Otherwise, I would suggest that it's your own YM installation that is faulty. -- Gary S.

Gary,
My sister the XP broad band user I am trying to PC to PC voice chat with is even less knowledgeable than me when it comes to PCs. I don't want here to screw up her machine especially being 2000 miles from me and I can not physically help her if thing get messed up. Can you tell me so I can relay to her where she would find the XP firewall exception list. And how to add YM's or is it the ports that may need to be added to the list if they are not there already. Do I need her to have all the above mentioned ports in the list ie ports 5061, 443, and 80 And in doing the above could it screw up her broad band cable connection or allow viruses or people to sneak past her and get on her machine?

TCP ports open or used?
Sorry to take so long to get back to you. I had an accident and was laid up
for a few days. In Windows XP, the firewall settings can be found in Control Panel. StartSettingsControl Panel, or StartControl Panel The entire thing is quite self explanatory once you open the Firewall settings applet. Hope that's sufficient to get you on the road.

The trick would be to add YM specifically to the exceptions on the XP firewall, with all of the ports you listed previously "opened". Looking at my own XP system (well, not really my own, it's one I'm borrowing -- I don't personally use YM), it has YM installed, with YM and YM FT Server (financial ticker), and both have been added to the firewall exception list. I'm wondering if the service you're trying to use also needs to be added to the XP firewall exception list. I would assume that the YM installation on that system would have automatically taken care of that, and the opening of the required ports, too, so perhaps reinstalling YM on that machine is the answer. But it's simple to add ports to the XP firewall exception list, manually, so I'd try that first. But, the above only applies if the setup works fine when the XP firewall isn't enabled. Otherwise, I would suggest that it's your own YM installation that is faulty. -- Gary S.

Terhune wrote: First, I'm not *real* familiar with these issues. This is a Windows 98 group, and not even the one I'd recommend for these issues. Your issues have a lot more to do with network protocols than with "Setup". Personally, I think you'd have better luck trying to find a Yahoo! forum that deals with YM voice communications and how to properly set up the computers that are using it (firewall settings, for instance, or possible YM port settings that will make things work better.) There are two major issues with ports. One is that the applications that are communicating with each other have to be using the same ports. If my email client is trying to communicate with an SMTP server (outbound email) using port 25, but the server is only listening to port 2525, the communication will fail. If your colleague is trying to send you messages on YM using a port that your YM isn't set to receive on, the communication fails. If your YM is sending to a port on the other machine that that machine's firewall is blocking, the communication will fail. Firewalls are intended to block communications on all ports except those which are explicitly opened. Typically, the port is opened only for use by certain application or applications, and/or only for certain protocols (like HTTP, HTTPS, SMTP, POP, FTP, etc.) But you use the word "crash" to describe your issue. Is YM really "crashing"? Or is there just an error? Is the result that YM just disappears and you have to restart it, or is there a general failure message causing you to forcefully kill YM (using Ctrl-Alt-Del, for instance) and restart it? Or are you simply getting a message that the communication can't be done? You need to be online to communicate, obviously. That is, your computer needs to be connected to the internet. But that does not equate to having IE or any other browser open. IE does not connect you to the internet, it is just a way to communicate with web servers once you've already got internet connection. Port 80 is the one most used for HTTP communications. If you can browse the web using IE, then the firewall isn't probably blocking port 80 for HTTP communications... But it might be blocking the use of port 80 for any other purpose. My guess is that the XP machine's firewall isn't properly set up to allow the use of YM on *that* machine, for the ports *your* YM is set to use. But why that would cause a crash is something I can't answer, and that's why I suggested that you reinstall your YM, to see if it will then properly handle whatever the other YM is sending (or handle the failure to communicate more gracefully, perhaps even producing an error message containing usable information, like what port(s) the incoming communication is trying to access.) I know I haven't actually answered your question(s) precisely, nor have I really addressed the specific problem you're having. But perhaps this will give you a slightly better understanding of what's going on and where you might look for whatever it is that is causing the problem(s). -- Gary S.

TCP ports open or used?
Should have added that the actual name of the applet is "Windows Firewall",
in Control Panel. Might make it easier to find, s. It can also be accessed via the Properties of the network connection for that adapter, but that method might challenge a newbie. -- Gary S.

Gary, My sister the XP broad band user I am trying to PC to PC voice chat with is even less knowledgeable than me when it comes to PCs. I don't want here to screw up her machine especially being 2000 miles from me and I can not physically help her if thing get messed up. Can you tell me so I can relay to her where she would find the XP firewall exception list. And how to add YM's or is it the ports that may need to be added to the list if they are not there already. Do I need her to have all the above mentioned ports in the list ie ports 5061, 443, and 80 And in doing the above could it screw up her broad band cable connection or allow viruses or people to sneak past her and get on her machine?
