Oracle Error Message
CLSGN-00109: No interfaces available.
Reason for the Error
GNS was unable to find any interfaces on which it can listen for requests. This error is likely caused by the incorrect specification of the list of interfaces on which GNS is not to listen. Alternatively, it may be caused by an error in system configuration.
Solution
Correct the list of prohibited interfaces if it was set incorrectly. If this is not the case, check the system configuration.
