Port 80 from hell

I'm having trouble running live sports scores,live weather maps etc...

1 of the pages says that If I'm having problems with it, that my firewall probably has port 80 locked.

the firewall is "Zone Alarm" but I've uninstalled the program it and the aplet still won't load.

I'm running win 98
533 amd w/128 ram.
IE 5.5 and netscape 6
cable modem.

The applets always loaded OK until about 1 week ago.


problem is in both IE and Netscape.

any type of live aplet just shows a little picture in the top left corner of
the page... like an unopened picture on a webpage.

I've heard that some pipelines have shut down port 80 recently to thwart hackers.
is this possible
that this is my problem ?

I use @home.com cable access... Is it possible @home has locked port 80 from Me ?
Evidently since they don't answer their mail The only way ot contact their tech support is to load java based chat....and I can't do that either. lol

is there somewhere in windows networking that my port 80 could be locked ?

Where exactly would a network admin check to see if port 80 was open ?

below is note from espn.com page I trying to access
******************************************************
Note: If you are connected to the Internet via a proxy server and you use
Netscape Navigator 3.0 or
an earlier version, GameCast may not run. You can get around this problem by
upgrading to the latest
verion of Netscape Navigator or by switching to Internet Explorer, or by
asking your network manager
to "open port 80" in your firewall server.

To my knowledge, if you can get to the internet then port 80 is open. Are you able to view web pages at all? Do you have the proper plug-ins for your browser (Flash, Shockwave, Quicktime, etc.) A lot of live feeds require these. Just a thought.

Do you have a server that you are running feeds from?  Or are you trying to download from the Internet?  A web server listens on port 80 for incoming HTTP requests.  You must allow inbound connections for port 80 on  your Firewall.  If you are trying to access these services on the Internet from your LAN, your Firewall must be configured to allow outbound traffic on whatever ports these services use.  Typically, a Firewall will allow all outbound traffic and restrict inbound.  Plus the Firewall should be configured to allow any established connections back inside your network.  For example, Napster connections are over TCP port 8875 & 8888, so if these ports are blocked at the Firewall, no worky.

Try and find out what ports are required for the services you need.  Do a search for TCP ports and enjoy!

I believe you need to:
Open up ZoneAlarm
Click the Security option
Click the Advanced option
Select the Internet Zone Custom Settings tab
Scroll down to Allow Incoming TCP ports: (none selected)
Check the box to the left of this option
A "Ports" text box displays
Enter 80
Click OK
Shutdown and Restart ZoneAlarm

This should do it.

What might be happening is @home is filtering incoming port 80 because of the Code Red Worm.  They shouldn't because you don't need to filter everything, you can filter just the worm itself at the routers, but they might be doing that.  Just my 2 cents, this exact problem is usually a web browser problem.  Make sure in Advanced Internet Options in IE under Microsoft VM you have everything enabled.

My comments assume you have made sure that your firewall "zone alarm" has been setup to allow incoming connections from the internet using port 80

> Is it possible @home has locked port 80 from Me ?

If they have, then you will _NOT_ be able to read this,
since using Experts-Exchange requires that your computer
can connect to port #80 on E-E's web-server.

On the other hand, if you are trying to run a web-server
on your computer, then it's possible that @Home will have
blocked "incoming" traffic to port #80 on your computer,
or that ZoneAlarm is blocking "unsolicited" traffic trying
to contact port #80 on your computer,
but this is a quite-different situation.

> any type of live applet just shows a little picture
> in the top left corner of the page

Have you changed the "security" settings in your web-browser,
to disallow the running of Java and/or JavaScript code?

When I access:

http://sports.espn.go.com/mlb/gamecast/index?year=2001&date=20010823&homeTeamAbbrev=cin&isLive=true

I get "You must be using a Java(TM)-enabled browser
to use this feature. We recommend Internet Explorer 5 or Netscape 4.5".

It's time they updated this message to state 'IE 5.5' or 'Netscape 4.7'.  :-)

If it worked until a week ago I would do the following.

1) Boot to a DOS prompt using the F8, or Ctrl to get the boot menu and choose option 5 ( command prompt ).
do

scanreg /restore

Choose a  registry date from before your problems.

I hope this helps !

Your computer must have a recent Java Virtual Machine to function properly. If you are having trouble
with Microsoft Internet Explorer, try using the Microsoft java help page:
