Hi,
I have redhat linux 9.0 on P4 machine. also I have windows XP on the same machine.

I am connected to internet through DSL router with static IP. I can ping my external IP address from linux, but I am not able to do it on windows through dos command window.

On linux, I installed tomcat 5, and I configured it to start my web application. I run tomcat as a standalone, no apache is runing

when I try to open my application from other linux machine using mozila browser, through the internet by typing:http://my_static_ip_address:8080/myapp

It works fine, and I can access my website.


If I try to do the same thing from any windows box it fails to load my application. even if I try to load the tomcat webpage by doing http://my_static_ip_address:8080, it fails. the browser will show a portion of it, only the tomcat logo.

I tried to use netscap 7 and IE 5, both fails to load my website page.

any help.

This is a networking issue.
1. Make sure your DNS is configured properly.
2. check your local hosts file.
3. check your DNS server settings if you're running a local DNS service.
4. check your firewall settings. make sure http is open for 8080 or whichever port you are using.
5. make sure your gateway/router is configured to your machine's internal IP.


I hope that helps.

do you think it is a network problem? even if I am able to browse my website through different linux machine, and this machine is not part of my LAN, it connects to my server through the internet. The problem happens only if I try to visit my website from machine that has Windows OS.

about your comments:

1. Make sure your DNS is configured properly.
in the router configuration, I choose to use the ISP DNS servers, I provided two IP addresses. should I do any thing more to check the configuration?

2. check your local hosts file.
I am not sure how can I do it? and what should I look for?

3. check your DNS server settings if you're running a local DNS service.
I do not have any local DNS service

4. check your firewall settings. make sure http is open for 8080 or whichever port you are using.
In the router configuration I mapped external IP:80 to 192.168.1.100:8080 and I enable it.

5. make sure your gateway/router is configured to your machine's internal IP.
yes, it is, actually I have only one machine connected to this gateway;
and this gateway connected to the internet via DSL modem.

Thank you very much.

well, here is some update, maybe someone will be able to help me.

I did the following test:

1- I created a simple html page that conatins "Hello world" text only. and I started the tomcat server on my linux box.

2- from a windows box, this I started IE 5.0 then

I typed: http://my_static_ip_address:8080/dir/test.html

result: the page is opend, and I can see the "Hello world"


3- I added a small JIF image, 1K bytes, to test.html, and I tried again
result: I am still able to open the page.


4- I added a big JIF image, 7K bytes, to test.html, and I tried again
RESULT: I can not open the page.

on ethereal, on the server side,I saw that, the client is trying load the page forever, and the server returns 200 OK, reassembled packets.
----------------------------

now, I am sure it is not a router problem, because I am already able to connect to my webserver. I think, it is problem in my IP/TCP configuration.

I still do not understand why I can visit my website from any other linux box.

any help
