I had a simular problem where the hosts couldn't see each other. I fixed that setting the ip address on each host.

First I check if multicasting works fine, by running the following from jgroup: On host1: ---------------------------------------------- java org.javagroups.tests.McastReceiverTest -mcast_addr 228.1.2.3 -port 45566 ---------------------------------------------- Onhost2: ----------------------------------------------- java org.javagroups.tests.McastSenderTest -mcast_addr 228.1.2.3 -port 45566 -----------------------------------------------
I am able to communicate perfectly without any problems.
Then I start jboss-3.2.3 using ./run.sh -c all on both the hosts. But I am able to see that both the nodes/servers cannot find each other as can be seen in server.log and it shows only one cluster member in both.
Probing further I tried receiving messages using : ---------------------------------------- java org.javagroups.tests.McastReceiverTest -mcast_addr 228.1.2.3 -port 45566 ----------------------------------------- on host1 and running the jboss-server on the same node. At periodic intervals I started getting some junk message from the jboss-server as soon as cluster-service.xml was deployed. The messages were from 127.0.0.1:45566. When I shutdown the jboss-server the messages stopped too.
Then I started the jboss-server on host1 and started two receivers on host1 and host2 respectively. I started getting the same junk messages from jboss-server on host1 (localhost) but not on host2(remote host).
This seems to be a problem with multicasting??? I have removed any firewall restriction using iptables -F in both machines too.But as I said in the beginning, the jgroup programs worked fine communicating with each other in a multicast group.
Everything including failover/farming etc will run well if this problem gets solved.
Any help is appreciated.
