Good; glad you are making progress. If you are running with the all config, use this: run -c all -b 0.0.0.0 -Djgroups.bind_addr=1.1.1.1 (or 2.2.2.2) JGroups will ignore 0.0.0.0 and pick an interface; using -Djgroups.bind_addr=1.1.1.1 lets you specify which. Also, clustering's HAPartition service uses the -b value plus the JNDI port (1099 by default) to make up a unique id for each node. If you use -b 0.0.0.0 (or -b 127.0.0.1) each node will come up w/ the same name -- not unique, which may lead to problems. To work around this you can manually specify the name by editing the cluster-service.xml file, replacing: <attribute name="NodeAddress">${jboss.bind.address}</attribute> with <attribute name="NodeAddress">${jgroups.bind_addr}</attribute> View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4222160#...
