PMDF Installation Guide
Tru64 UNIX Edition

By default, a TruCluster treats TCP ports between 512 and 1024 inclusive as "dynamic" ports that only one node of the cluster may use at a time. PMDF-TLS depends on ports above 512, so this default behavior must be overridden to allow TLS services on multiple nodes of a cluster.

To allow every node in a TruCluster to provide TLS services, place the following entries in the /etc/clua_services file:

smtp-tls 465/tcp in_multi imap-tls 993/tcp in_multi,static pop3-tls 995/tcp in_multi,static

Once the TLS ports have been defined in /etc/clua_services, run:

# cluamgr -f

to pick up the changes.
