Unable to connect with linux system to other linux system
 

Hello

I have developed a web project in eclipse. Create a war file of that

project n send it on other linux system. The problem is that when i try to

access that project on my system it gives me error "Unable to connect.

Firefox can't establish a connection to the server at xxx.xxx.x.xx:8080"

I m accessing this via apache-tomcat. what is going wrong with me?

You are trying to connect on what method? Using your project that you create?

Or you mean that the web page is not accessible?

Your question is not clear, or you want to connect remotely to another server?

Or the apache-tomcat is not functioning?

Which one is it?

I have typed in my address bar "http://ip address:8080/myproject/myfile.html" When i try to ping that ip address it pinged. My other web pages are accessible.

on local network are you able to see the page?

but not on the internet?

if local network is fine and not on the internet, then you might need to check whether port 8080 is open to the outside world and is port forwarded to your machine hosting the page.

I am trying on local network only and I am getting an error "Unable to establish the connection to server" or sometimes "Server is taking too much time to respond". this is happening with Linux system only.

If I deploy the .War file on Win OS machine I am able to connect the machine and can see the desired web page.

Even I can access Win machine from Linux system. But not possible vice versa. What can be the cause of this?

have you installed and configured apache as well as set iptables and SELinux to allow for the port 8080 connection?

check out this link, configure Apache to use different port:

http://www.groovypost.com/howto/apac...ultiple-ports/

I am using centOS 6.4. There is no httpd.conf file in conf folder.

again, have you properly installed and configured Apache web server as well as configured both IPTables and SELinux to allow access to the server. from the sounds of it that answer is NO. please do so, then your problems will change or go away.

Please install and configure Apache.

Use this keyword to search on Google.

"How to install Apache on CentOS"

"How to configure Apache on CentOS"

"CentOS Apache configuration Guide"

You need to help yourself aside from asking help from others.

is it really 8080 for apache ?

from the first view seems apache is not correctly installed! please install and configure it:

when apache-tomcat pair is used then to access the site you should use:
http://sitename:apache_port and not the tomcat one.

prior to that have you configured tomcat to run with apache using modules like "mod_jk" or "mod_proxy" ?

checks after configuration:

Is the apache service running ?
Is the tomcat service running ?
check mod_jk.logs (if it is used) to see if apache is bale to communicate with tomcat ?

Please type this on the terminal and post back the result:

When i try this. .

$service httpd status
httpd: unrecognized service

it means that you haven't installed apache..

please check post #7;check the link on how to install and configure apache..

I have installed apache n configure it. Now run command # service httpd status it gives me "httpd dead but subsys locked". What does it means?

When i run this command as a root user it gives "httpd (pid 3902) is running..."
