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

Copyright (c) 1991, 2009, Oracle. All rights reserved.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT=1521))
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: connect(6, 0x1002A4EC0, 32, SOV_DEFAULT) Err#128 ENETUNREACH
4200: close(6) = 0
