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 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?? Because I crash at my end has noting
to do with me perhaps but their settings of the firewall?

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,
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?

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,
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?

(Phone In).
Where on do I find if theses ports are open and how could I open
one if I need to?

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. Again, sorry about the delay.

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?

It's a given that port 80 is open on both machines for HTTP, but I don't

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,
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?

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).

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.

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.
