      • ALLOW
        • SSH access to the license node (TCP port 20 + 22)
        • LOM access to the license node (KVM, EXASOL installation ISO mounted)
        • LOM access to the data nodes (KVM)
        • HTTP/S access to all cluster nodes (EXAoperation web UI ,TCP 80/443). The web UI is running as a cluster service and can be accessed from any cluster node

      Operating

      • ALLOW
        • Database port clients use to connect to the database (default TCP 8563)
        • HTTP/S access to all cluster nodes (EXAoperation web UI, TCP 80/443)
        • SSH access to all cluster members (TCP port 20 + 22)
        • To get most out of the web UI each cluster node should be able to access the LOM of each other (ipmitool is used for providing basic hardware vitality information)
