However, we should also list the additional ports used by the clustering subsystem (both UDP and TCP)...

Hello everyone out there in JBoss land...
We are trying to put some firewall documentation together for our customers
so they understand the requirements of our system. When we started putting
this together we noticed some unfortunate behavior in JBoss with random port
selection. This type of port selection is obviously not good for firewalls
because no static rules can be written to it. So I started investigating
how to make these ports static. Thanks to the forum and the mail list I was
able to figure out how to get JNDI to stop opening his random port by
setting the RmiPort property. As we only use JBoss as an EJB container we
were also able to turn off several of the MBeans that we didn't need.
Unfortunately, we still have a few ports that we don't know where they are
coming from. Below is a listing of the ports JBoss is using in our config.
java TCP *:1099 (LISTEN) -> JNDI port java TCP *:4444 (LISTEN) -> RMI port java TCP *:4445 (LISTEN) -> another RMI port set by RmiPort prop java TCP *:8083 (LISTEN) -> Webservice port java TCP *:54387 (LISTEN) -> Unknown (seems to be randomly selected) java TCP *:54388 (LISTEN) -> Unknown (seems to be randomly selected) java TCP *:54389 (LISTEN) -> Unknown (seems to be randomly selected)
ok.. we have two questions (with several sub questions).
1) Is there a way to disable the Webservice MBean? We tried commenting it
out but kept getting errors from the EJB-Manager, which we assumed was vital
to serving up EJBs in the container. Correct me if I am wrong, but the
Webservice is used for downloading EJB interfaces if they are not know by
the client. We won't need this because our Java application will have all
the interfaces it needs inside a deployed jar file.
2) What are the three consecutive random ports that keep showing up (54387,
54388, and 54389 in the example above), what uses them, and if they are
needed can them be statically set?
