Hi ,

I am running Jboss server 4.2.3.GA on my machine , and I am able to access the port locally ( eg: http://localhost:8080/ ) and is working fine with all my JSP Servelet application . But here the issue is , if I try to access the port from outside ( eg: http://192.168.xxx.xxx:8080 ) , I am not able to get the port number. I tried enabling the HTTP port 80 , but nothing happend .

I am using

Fedora 10
Kernel 2.6.27.9-159.fc10.x86_64 ( 64 bit )
Gnome 2.24.2

How can I open the port ?

Thanks in Advance
Peeths

A few things I would look for:

Is that the correct ip address of the jboss server?
can you ping the address?
What ports does nmap show open on the server?
can you telnet to the port on the server?
is iptables being used on the server?
is the jboss server blocking access?

The IP address is of the machine in which Jboss server is running

I am able to ping to 192.168.xxx.xxx ( without the port number )

telnet 192.168.xxx.xxx
Trying 192.168.xxx.xxx...
telnet: connect to address 192.168.xxx.xxx: Connection refused


telnet 192.168.xxx.xxx:8080
telnet: 192.168.xxx.xxx:8080: Name or service not known
192.168.xxx.xxx:8080: Unknown host

From Windows Machine

C:\>telnet 192.168.xxx.xxx
Connecting To 192.168.xxx.xxx...Could not open connection to the host, on port 23: C

[root@localhost ~]# nmap 192.168.xxx.xxx

Ho can i open the port 8080 for http request ?


I am not sure of these 2 questions , I dont know whether iptable is being used in the JBoss server , how can i check that ?

How to find out whether Jboss server is blocking the access ?

Please help

Thanks
Peeths ....

ps -ef|egrep -i 'java|jboss'
this to make sure jboss is running....

netstat -ntalp|grep java
this to see on which port/address is running. should be something like: 0.0.0.0:8080 or some ip address like: 192.168.0.1:8080.

if this doesnt work it means jboss is not running or its running... but somehow weird, you will need to check the config.

Ops, I forgot, if everything is fine... you see the bg process and the 0.0.0.0:8080 or something like that, could be your firewall the issue.

ps -ef|egrep -i 'java|jboss'




netstat -ntalp|grep java

I don't know what the issue is ............... is there something that is blocking the connection like firewall or something ?

You jboss is running on localhost:

tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 3347/java

You need to change the configuration of jboss from 127.0.0.1 to 0.0.0.0 then restart jboss and try again.

I tried changing this too ... but i didnt get any thing positive , how can i check that there is any firewall blocking the port ?

iptables -L -n -v

Also I forgot, but if you changed it... you need to check netstat if you really have it on other adapters then localhost. If you jboss still runs on 127.0.0.1:8080 doesnt matter the firewall. Make sure that is running like: 0.0.0.0:8080 then think of the firewall.

I tried checkin with netstat -a by starting up the Jboss server , it is still pointing to 127.0.0.1 , how can i change it to 127.0.0.0

Thanks

Launch your server as follows:

$JBOSS_HOME/bin/run.sh -b 0.0.0.0

It will then listen to any address and not only localhost...

HTH
F.

thats cool ........... thanks ............ i guess its working .......... how about tomcat , weblogic and other servers ... ? how can i make them listen so that it is acceble from out side the machine ............ ?

EDIT : and is it that this will work only with the current ip of the machine ( 192.168.xxx.xxx) and the port ( 8080 ) , or is that other port also might be open ........

How does this work , is it making one port open for any one accessing the network .... ? is there any security risk on this ... ?

For tomcat you have in server.xml a part where you define the port, like port 8080, lets say you will have to add also: address="0.0.0.0", something like that

Example: <Connector port="8080" address="127.0.0.1" ... />

Hey ... here i tried accesing the JBoss from an out side machine , and it is not working , i tried in the same machine with the IP and it is working , i doubt there is some firewall that is blocking the access .....


Thanks

Did u check to see if jboss (if we talk about jboss) is running at is should?

netstat -tnalp|grep -i 8080
or
netstat -tnalp|grep -i java

like i said before should be 0.0.0.0:8080
make sure is running, also iptable -L -v -n, see if you actually or maybe have some firewall setup.
