Enabling remote access to JBoss 4.2

Today I had an issue remotely accessing my JBoss instance running on another machine. Unknowingly, JBoss 4.2 binds specifically to 127.0.0.1 by default (see below for me details). Thankfully they had a simple solution; just append -b 0.0.0.0 to your startup script to bind to all interfaces. So to start JBoss on linux when I know I want to access it remotely I do:

./jboss/bin/run.sh -b 0.0.0.0

ReadMe.html content on this subject:
"JBossAS now binds its services to localhost (127.0.0.1) *by default*, instead of binding to all available interfaces (0.0.0.0). This was primarily done for security reasons because of concerns of users going to production without having secured their servers properly. To enable remote access by binding JBoss services to a particular interface, simply run jboss with the -b option. To bind to all available interfaces and re-enable the legacy behavior use -b 0.0.0.0. In any case, be aware you still need to secure you server properly."

Thanks James. Definately helped me out. Spent an hour or so figuring out why I could not access my JBoss instance. But now I can. Good post.

thanks for the tip. After using it for a while, I found that having <Connector address="0.0.0.0" ..> in server.xml do the job.

Thanks James. This resolved my problem.

I am trying to do the same when starting JBoss as a Windows service. I've tried to put

-params "-b 0.0.0.0" in the JavaService command line after the -start. But it didn't work. With this param, two JBOss services failed to start: WebServices and Naming. The exception said it cannot bind address 0.0.0.0. Any idea??

I am using win xp sp2 and JBoss 4.2.3.GA.

If you use the wrapper service from
http://wrapper.tanukisoftware.org
to get jboss to run as a windows service you simply pass the -b 0.0.0.0 in the wrapper.conf file
wrapper.app.parameter.1=org.jboss.Main
wrapper.app.parameter.2=-b 0.0.0.0

You might find RHUB’s http://www.rhubcom.com, Remote Access solution interesting. It is compatible with multiple platforms and provides all privileges for complete control of the remote system. Has some very impressive features.

Cheers again

Thanks James.
I'm using Eclipse + WPT plugins, so on the Server tab double click your JBOSS AS v4.2 instance, select 'Open launch configuration', next the 'Arguments' tab and finally pre or postpend the '-b 0.0.0.0' parameter leaving a white space for other arguments if necessary.
