I would like to do some hardening to JBoss eap by closing all tcp ports except 8080 by unloading/ cutting out some services and config files. I do not want to loose management via jon agent and statistics query via twiddle. Can you please tell me which ports or services I should keep running to not break jon or twiddle connection? How jon agent connects to jboss 4.2.0? Does it use tcp connection or inter process communication? Jboss, jon agent and twiddle are on the same machine. Linux RHEL4.
