Thank you very much for the toolkit ;) My feeling was also on my multicast support. But i' ve read more documentation for my Linux and i think that my servers support MULTICAST like explaned on my first message (compile kernel support and add route + test with tcpdump)
So this toolkit seems confirme the fact that my servers support multicast. When i test on agnes with target ovea-inspiron i've: java -cp tomcat-replication.jar MCaster 224.0.0.1 45564 ovea-inspiron Usage MCaster [address port message] BEGIN TO RECEIVE SENT:ovea-inspiron1 RECEIVED:ovea-inspiron1 FROM /192.168.2.102:45564 SENT:ovea-inspiron2 BEGIN TO RECEIVE RECEIVED:(gtcp://192.168.2.103:400cluster1 FROM /192.168.2.103:45564 SENT:ovea-inspiron3 BEGIN TO RECEIVE RECEIVED:(ftcp://192.168.2.102:400catalina FROM /192.168.2.102:45564 SENT:ovea-inspiron4 BEGIN TO RECEIVE RECEIVED:(gtcp://192.168.2.103:400cluster1 FROM /192.168.2.103:45564 And when i test on ovea-inspiron with target agnes i've: java -cp tomcat-replication.jar MCaster 224.0.0.1 <http://228.1.2.3/> 45566 agnes Usage MCaster [address port message] BEGIN TO RECEIVE SENT:agnes1 RECEIVED:agnes1 FROM /192.168.2.103:45566 SENT:agnes2 BEGIN TO RECEIVE RECEIVED:agnes2 FROM /192.168.2.103:45566 SENT:agnes3 BEGIN TO RECEIVE RECEIVED:agnes3 FROM /192.168.2.103:45566 SENT:agnes4 BEGIN TO RECEIVE RECEIVED:agnes4 FROM /192.168.2.103:45566 SENT:agnes5 BEGIN TO RECEIVE RECEIVED:agnes5 FROM /192.168.2.103:45566 SENT:agnes6 BEGIN TO RECEIVE RECEIVED:agnes6 FROM /192.168.2.103:45566 SENT:agnes7 BEGIN TO RECEIVE RECEIVED:agnes7 FROM /192.168.2.103:45566 So it's not a multicast probleme but most a configuration probleme. ovea-inspiron sent is ok but the received is empty ? Some suggestion(s) ?
