I'm using Wildfly 8 for my server, in my server I use Infinispan (which use Jgroups) for cluster cache. I want to know which ports that Jgroups/Infinispan uses, so I can open these ports for communicating between server nodes without disable my Linux firewall. Thank you.
You may find these answers in your wildfly/standalone/configuration/ directory. I assume you are using standalone-full-ha.xml configuration:
<!-- By default you are using UDP stack -->
<subsystem xmlns="urn:jboss:domain:jgroups:2.0" default-stack="udp">
<!-- Those ports are used for communication -->
<socket-binding name="jgroups-udp" port="55200" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45688"/>
<socket-binding name="jgroups-udp-fd" port="54200"/>
