[jboss-user] [Clustering/JBoss] - JGroups mulitcast test program problem, cannot use bind_addr

Hi, I'm new to this forum. I did attempt to search for a topic similar to mine but was not successful. Please let me know if there's a similar topic. I'm currently attempting to test Multicasting using the JGroups test programs: org.jgroups.tests.McastReceiverTest org.jgroups.tests.McastSenderTest Each of the two boxes I am using have 2 NICs each. Only one of these ethernet cards allows communication between servers (the other is port isolated). So, I must use bind_addr to specify which NIC to use. However, I'm receiving the following error when attempting to use the programs with bind_addr: java.net.SocketException: Can't assign requested address This error also occurs on a simliar environment that only has 1 NIC. I also receive the same error when I specify "-use_all_interfaces" or when using the 1_4 versions of these test programs. (Note: When not specifying a bind_addr in my 1 NIC environment, there is no error and I am able to send/receive multicast messages correctly. If not specifying a bind adress in my 2 NIC environment, no error is displayed, but no messages are received ) Can anyone tell me why this error is occuring? See below for more specifics about my environment. OS: AIX JRE: java version "1.4.2" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca142-20060421 (SR5) (JIT enabled: jitc)) jgroups version: 2.4? Note: The servers are actually virutalized LPARs, and therefore the ethernet cards associated with the bind_addr IP are also virtual. Any help you can provide on this topic will be appreciated.
