JBossCache running on windows & linux
Hi,
I'm running one jboss cache node on a linux and the other on windows and for some reason they don't seem to see each other. Here's how the set up looks
[linux]<------>[switch]<------>[windows]
the cache-service.xml is using multicast, repl_sync.
I have checked that the multicast is working.
using :
java org.jgroups.test.McastReceiverTest -mcast_addr -port
and
java org.jgroups.test.McastSenderTest -mcast_addr -port
multicast seems to work. the same cache-service.xml is on windows as well as linux (that would take care of incorrect culter name in the xml).
Now if i start an extra node each of the os the node in the same os can see each other and form a group.
So the next thing i did was to run just the McastReceiverTest on the started the cache node on linux and win, here's something i found interesting McastReceiverTest shows constant messages being received from linux cache but absolutely nothing from the windows cache node.
Also on windows the UDP tag's loopback attribute is set to true in the cache config.
Is there something i'm missing here.
Any pointers would be helpful.
