Symptoms

Lsnrctl start appears to work but issuing lsnrctl commands against same running listener yields the following stack:

LSNRCTL for Solaris: Version 11.2.0.1.0 - Production on 12-MAY-2010 13:23:45

TNS-12543: TNS:destination host unreachable
TNS-12560: TNS:protocol adapter error
TNS-00513: Destination host unreachable
Solaris Error: 128: Network is unreachable





Truss of lsnrctl status yields:

4200: close(6) = 0
