You can utilize the JMXServiceURL on the constructor of the jmx ConnectorServer to establish a reference to a specific host. (which it seems is the way you have setup)
As for RMI, its registry can only be created in code with a port parameter. http://docs.oracle.com/javase/8/docs/api/java/rmi/registry/LocateRegistry.html Notice there's no createRegistry() with a host option? There are a number of RMI specific system properties. https://docs.oracle.com/javase/8/docs/technotes/guides/rmi/javarmiproperties.html The one called -Djava.rmi.server.hostname=127.0.0.4 seems like it might be the one, but then again it makes no mention of how it binds the RMI ServerSocket. Also of note, the javadoc seem to indicate that the only way to accomplish this is with a custom RMISocketFactory implementation. https://docs.oracle.com/javase/8/docs/api/java/rmi/server/RMISocketFactory.html Joakim Erdfelt / [email protected] On Tue, Jan 26, 2016 at 5:50 PM, Steven Katz <[email protected]> wrote: > Hi, > > Thanks for the reply. > > I am, in fact, trying to start jmx/rmi on the loopback address 127.0.0.4, > but jetty insists on starting the rmi regisrty on 0.0.0.0 when it detects > you are using a loopback address (that the code I posted). > > I have configured jetty-jmx-remote.xml > > I am starting with these properties on the commandline: > jetty.jmxremote.rmiport=1199 jetty.jmxremote.rmihost=127.0.0.4 > > After it starts, "netstat -an | grep 1199" shows > > TCP 0.0.0.0:1199 0.0.0.0:0 LISTENING > > Which indicates that it is listen on all address not just 127.0.0.4 > > Is there any way I can limit it to just 127.0.0.4? > > *Steven Katz | *Senior Director, Architecture > *Aol*Platforms*.* > *office**:* > * 617.874.5448 <6178745448>* > *email: [email protected] <[email protected]>* > > On Tue, Jan 26, 2016 at 7:38 PM, Joakim Erdfelt <[email protected]> > wrote: > >> I think you meant the jmx ConnectorServer, not the ConnectorService >> >> That address (127.0.0.4) is loopback, and will start the JMX registry. >> >> Test it yourself. >> >> InetAddress addr = InetAddress.getByName("127.0.0.4"); >> System.out.printf("Addr %s isLoopbackAddress = %b%n", addr, >> addr.isLoopbackAddress()); >> >> If you get false, then you have a more fundamental configuration issue to >> noodle through, as the default implementation of >> java.net.Inet4Address.isLoopbackAddress() just checks that the first octet >> for the IP is 127. >> >> >> Joakim Erdfelt / [email protected] >> >> On Tue, Jan 26, 2016 at 4:54 PM, Steven Katz <[email protected]> >> wrote: >> >>> I'm trying to start jetty so that jmx and the rmi registry are started >>> on a loopback address (specifically, 127.0.0.4).
