Tomcat works fine on deployed machine, but not on others machines in network

[Avijit Dutta <av...@honeywell.com>]

We have installed tomcat in a linux machine, and when we invoke http://<linux
machine ip>:8080/ from that linux machine, it is showing properly.
But, when we try to access the same URL from another machine in the same
LAN, then nothing is coming up.
Please help.
 
The 2nd machine is able to ping the linux machine's IP.
Also. firewall is disabled.
 
~Thanks

Let's get rid of the three obvious ones first: binding to a particular
address, odd firewall settings on the test client, and odd browser settings
on the test client.

1) Run "netstat -an | grep 8080" on the Tomcat server.  Is Tomcat bound to
*:8080, or is there a specific IP address instead of *?  If there's a
specific address, you may want to change your connector settings.

2) From the test client, run "telnet <linux machine ip> 8080".  Do you get a
connection?  Is the connection refused quickly?  Or does the connection fail
slowly?  If you get a connection using telnet, check your browser settings
on the test client - particularly proxy settings.  If the connection fails
slowly, check the firewall on the test client (or you may already know that
it's disabled).

Oh, and 3) are you *absolutely* sure the Tomcat server is allowing the
traffic in and out, and there are no odd remnants of firewall rules lying
around?
