Disabling of services on a cluster

Hi,

OS: Tru64 UNIX 5.1 + TruCluster 5.1
Hardware: Two member cluster of ES40s with memory channel interconnect
Storage: HSG80

Question: Can the following services be disabled, or at least
"wrapped" using tcp wrappers, in a cluster environment?

        - portmap (/usr/sbin/portmap)
        - exec (/usr/sbin/rexecd)
        - login (/usr/sbin/rlogind)
        - shell (/usr/sbin/rshd)

I'm wondering if they are used by the cluster for any type of cluster
administration. If so, could we wrap them and allow the cluster members
to connect via their private (10.0.0.*) IP addresses?

mc0: flags=1100063<UP,BROADCAST,NOTRAILERS,RUNNING,NOCHECKSUM,CLUIF>
     inet 10.0.0.1 netmask ffffff00 broadcast 10.0.0.255 ipmtu 7000
