I have two ethernet cards on same server (Redhat As
2.1).  I want both Ethernet cards listener to port
1521.   

The listemer.ora file:
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST =
server1)(PORT = 1521))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST =
server2)(PORT = 1521))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /home/app/oracle/product/9.2)
      (PROGRAM = extproc)
    )

==========================================================
I tried to start it up:

%lsnrctl start

Does anyone know how to make it work?
