2.2.2. Enabling IP Ports on Computers That Run luci
To allow client computers to communicate with a computer that runs luci (the Conga user interface
server), and to allow a computer that runs luci to communicate with ricci in the cluster nodes, you must
enable the IP ports assigned to luci and ricci. Table 2.2, “Enabled IP Ports on a Computer T hat Runs
luci” lists the IP port numbers, their respective protocols, the components to which the port numbers are
assigned, and references to iptables rule examples. At each computer that runs luci, enable IP ports
according to T able 2.1, “Enabled IP Ports on Red Hat Cluster Nodes”. (All examples are in Section 2.2.3,
“Examples of iptables Rules”.)
Note
If a cluster node is running luci, port 11111 should already have been enabled.
