I am new to linux...
I set up a server using Apache Tomcat 5.5.26 using jdk 1.6.
Also created environment variables CATALINA_HOME and JAVA_HOME as told.
I tested it to see if the server is working by typing in http.
address on the same PC browser
(http://localhost:8080 or http://ipaddress:8080),
Tomcat server's main Page I can see.
Even I developed sample project and deployed it on the server.
I can access that one also from server PC.
But when I try to access it from another pc on the network it gives error as

Can't establish connection with the server at ipaddress:portno
I asked our admin to disable the firewall, then also the problem cant be solved.

Do I have to go for some more configurations to access server from other computers.

I am using fedora core 9
My IP address is reachable from the Internet
I have DHCP
my mask is 255.255.255.0
I installed Tomcat on /mnt directory and jdk on /usr for convenience.

can anyone please help?

Thanks for the reply Khabi.
I tried the command netstat -apn | grep 8080. It gave the output like this ---
tcp 0 0 :::8080 :::* LISTEN 2682/java
How can i make changes to this one?

Assuming you're all talking about the Tomcap server.xml file, I believe it's here
/usr/local/tomcat/conf/server.xml

Hello khabi after disabling the firewalls on almost all pcs even on server i managed to run my server.
But you gave me that command.
Its output was not as you given to me. I have given it there.
Where can i find that configuration file.

Neil, sorry I didn't see this sooner. That command I gave you was assuming you were only using IPV4 on that box, you're using V6. If memory serves that line you posted is pretty much the same as the one I did. You shouldn't have to worry about changing server.xml.

Sounds like there was a firewall somewhere that was blocking you.
