What does org.jboss.Main -b 0.0.0.0 mean?

Hi,

I'm trying to debug a linux script that isn't reporting when JBoss is running, when it tries to run or stop the server.

This is the statement, and it's being used as a condition for echoing whether the server is active:

 pgrep -fn "org.jboss.Main -b 0.0.0.0



So for example, for stopping the server the script is


For starting the server, the script is



, and in both cases, the dot "." keeps getting echoed indefinitely, so that we have to break out.


What I'm asking, if anyone can help, is

1.  What does the -b 0.0.0.0 mean?  Are these really necessary, if we're just trying to see if the server is running?

2.  If these parameters seem necessary, is there an alternative way of doing the same thing, that we can try?



Thanks and regards,




 
Marshal

I know that your post is from several weeks ago and you have already resolved your problem.  I'll reply anyway in case may help someone else in the future.

The -b option is used to specify the binding address.  -b 0.0.0.0 means bind to addresses for all interfaces.

You should be able to set this in the appropriate configuration file (file name/location and other details depend on server version and installation decisions):

If it's not defined, the default binding address is 127.0.0.1 or localhost, meaning that clients cannot talk to the JBoss server unless they are located on the same machine as the JBoss server itself. This is a security feature to ensure that the server doesn't get exposed to a cruel outside world until you've got everything properly configured and locked down.

Tim, thanks for the detail.  I'll put this in the pim.

Yeah, I always forget that and then can't figure out why clients can't talk. JBoss isn't the only product that gets shipped that way, either.
