[JBoss-user] [Clustering/JBoss] - Re: Protecting cluster from rogue nodes
Hi I can explain how we did the setup of our cluster. Perhaps that will help you. We have 2 Cluster Nodes. Each of them has 2 NICs. 1 NIC of each node has a valid IP for the subnet where they are attached. The 2nd NIC of each node is used as an interconnecten between the 2 nodes. So they both have a "fake" network address. Moreover the nodes are connected directly (it's like you connect them with a cross cable directly fron NIC to NIC). To avoid the MC broad cast, I enabled MC features only for the 2nd NIC on each node... That's it. | 192.168.1.0/24 LAN | === | || | | eth0: 192.168.1.1 | eth0: 192.168.1.2 | ++ | Node 1 +-+ Node 2 | eth1*: 1.2.3.1 eth1*: 1.2.3.2 | | *) connected with a crosscable from NIC-to-NIC | Hope that helps ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3863501#3863501 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3863501 --- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

The best cluster protection is to put all cluster servers into a separate network segment, so you can restrict UDP broadcasts to that segment. Using encryption or just different broadcast IP's might do the job from a technical point of view, but isn't 'waterproof' for a production environment.
