[jboss-user] [Installation, Configuration & DEPLOYMENT] - JBoss Ports and what's behind them

Hello, I am using the JBoss 4.2.2 server (atm as my development environment) for a project which was, before, based on TomCat only. However, the application in development now needs additional features (to be precise: EJB3). I am interested in the port list (because I need to know which may be firewalled and which not). I examined the current server configuration with TCPView (I'm on Windows) and came to this result: | 1098 JNDI | 1099 JNDI RMI | 3873 Default EJB3Connector | 4444 JRMP-Invoker | 4445 Pooled Invoker | 4446 Connector (Core Component) | 8009 Coyote AJP Connector | 8080 Webserver | 8083 Webservice | 8093 JBossMQ UIL Service | 3 x anon Various anonymous TCP ports | Anyway, I am interested in this: which ports are really in use when only TomCat is used as well as EJBs (which are accessed from the client using JNDI lookup). From what I can see I would guess these ones are really used: - 1098 + 1099 - 3873 - 4444 (really used when using remote ebjs with a client?) - 4445 (really used when using remote ebjs with a client?) - 8080 I am absolutely not sure about these (and whether I could firewall them): - 4446 (can it be blocked when not using connectors to integrate EISs?) - 8009 (can it be blocked when not using connectors to integrate EISs?) - 8083 (can it be blocked when not using WebService without breaking EJB3 and TomCat?) Of course I was able to figure out roughly what each of the services behind the ports do, but still, I'm not 100% sure whether I should/could block them or not. What I am looking for is a conservative firewall-setup where only the really required ports are opened. Kind regards and thank you for your help, Marius View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137339#...
