http://localhost/ works but http:/// doesn't
http://localhost/ works but http://<ip address>/ doesn't. Internet Explorer
gives a "Cannot find server" message.
I have tomcat 5.0.18 (without apache).
I can ping my IP externally. I have port forwarding enabled on my router.
Is there something I need to do to server.xml to enable this to work?
Thanks

Hello Christopher,
I changed tomcat to use port=80 and http://192.168.1.100/ works but
http://<ip address>/ still does not work.
What do you suggest?
Thanks,
Ted

RE: http://localhost/ works but http:/// doesn't
Posted by Christopher Watson <c....@zen.co.uk>.
Doug.
Is your tomcat on port 80 or port 8080 ...
You say
> If I try http://192.168.1.100:8080/, it works.
Does http://192.168.1.100/ (i.e. default http port 80 equivalent to
http://192.168.1.100:80/) work ?
If both the above work, what is at port 80? IIS ? Apache?
and what are you using to 'route' between post 80 and port 8080?
Is that configured OK to work with your public IP address?
If there's not 'routing' between 80 and 8080
Then, does http://thepublicipaddress:8080/ work - (this may well have
been stopped by the isp's firewall).
If it does, you may want to start tomcat on port 80 ??
Look in conf/server.xml for line that starts
<Connector port="8080"
and change it to
<Connector port="80"
Hope this helps.

It's not there. Another thing is I tried to ping the computer again from a
different external computer
and got back no response. The first ping attempt was actually from a
Linksys support person who
said ping worked but I can't verify that personally of course. I can send
you my IP in email if you're
willing to try that too (what email address?).

The public IP. If I try http://192.168.1.100:8080/, it works.

The box was not checked.
Also, there's an Internet Connection network connection of type "Internet
Gateway" that shows some services that you can enable
Internet users to access. For that, http is unselected.
If I select it, and select edit, it has the following fields and values:
Field: "Name or IP address of the computer hosting this service on the
network"
Value: 192.168.1.0
Field: "External port number for this service"
Value: 80
Field: "Internal port number for this service"
Value: 80
I tried playing around with the settings here but I'm not sure what to use.

Last thing first. I did find you can set the IP with address=??? in the

You keep mentioning the linksys, so I have to ask, are you trying to use the
actual IP of you machine (192.168.1.100) or the public IP assigned to the
Internet side of the Linksys (assuming it is connected to the Internet)?

There are primarily three cases that can happen with your setup:
1.
Call http://localhost-- no response
Call http://machineIP-- no response
Call http://publicIP-- no response
Tomcat is not running.
Firewall on machine is blocking all IP traffic(rare but can happen).
TCP/IP stack is corrupt.
Since localhost works this is not the issue with yours.
2.
Call http://localhost-- response
Call http://machineIP-- no response
Call http://publicIP-- no response
Tomcat is misconfigured. Address setting for IP other than machine IP.
Firewall is enabled/running on machine(not external unit).
3.
Call http://localhost-- response
Call http://machineIP-- response
Call http://publicIP-- no response
External firewall is misconfigured.
Machine firewall is misconfigured. (Some firewalls treat requests to
yourself as localhost and do not filter them. Try accessing http:/machineIP
from another machine on the network if available.)
Confirm which category you fall into. Then check the items listed.
What version of windows are you running?
If 2000 or higher go into network connection properties and select the
Ethernet adapter that is connected to your linksys. Click on the advanced
tab and confirm that the box beside firewall is NOT checked.
If you are category three and the machine firewall is off then you have a
problem with your Linksys.

Ted,
Sitting at you windows box that is running TC you can open IE and access
http://localhost but if you try to access http://yourMachinesIP it fails.
>From a command prompt ping localhost. Then ping the IP of your machine.
Notice that localhost resolves to 127.0.0.?
Do an ipconfig /all from the command promrt. Confirm the IP of your machine.
Are you running ANY firewall software? Disable it on a temporary basis to
test. Then configure it to allow http port 80 traffic through.
I am not aware of any setting that binds tomcat to an IP like apache can.
Although you can filter on an IP.
