javagroups and network masks

[byers]

Hi,

Is it possible to choose the IP range where JBOSS will search other JBOSS instances ? Can someone explain clearly what means the mcast_addr=228.1.2.3 in the javagroups configuration section of the default cluster-service.xml ? Documentation says to use this route :
Destination : 224.0.0.0
NetMask : 240.0.0.0
...
Why ?

Thanks,
Byers

OK, I solved my problem.

I have 2 servers with 2 network cards : 1 for the LAN, and 1 for a direct connection (crossed cable).
Because my machines have a common virtual IP (Win 2k cluster), I got communication crashes.
So I added the "bind_addr=XXXXXXX" attribute into the node (cluster-service.xml) to specify where listening JBOSS lookups, that is to say the interface used for direct link!

Sorry,
Byers
