Clusters - Disabling or restricting autodiscovery
When using tomcat clusters on an untrusted subnet or using a routable multicast address, i see the potential for a rogue tomcat instance to join a cluster in order to hijack session information. Is there any way to restrict autodiscovery of cluster membership to a known list of IPs or disable auto discovery alltogether?

Clusters - Disabling or restricting autodiscovery (security question)
When using tomcat clusters on an untrusted subnet or using a routable multicast address, i see the potential for a rogue tomcat instance to join a cluster in order to hijack session information. This doesn't seem to be cured by any firewalling of incoming connections to the valid servers, as, from what i have read, the valid servers will conect to the rogue sever on the address/port specified by the rogue server's multicast transmission and will transfer session data to it. If this isn't correct, I'd be grateful for an explanation. If this is correct, Is there any way to restrict autodiscovery of cluster membership to a known list of IPs or disable auto discovery alltogether?

This doesn't seem to be cured by any firewalling of incoming connections to the valid servers, as, from what i have read, the valid servers will do a unicast conect to the rogue sever on the address/port specified by the rogue server's multicast transmission and will transfer session data to it.
