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

Starting /home/app/oracle/product/9.2/bin/tnslsnr: please wait...

TNSLSNR for Linux: Version 9.2.0.5.0 - Production System parameter file is
/home/app/oracle/product/9.2/network/admin/listener.ora Log messages written to
/home/app/oracle/product/9.2/network/log/listener.log Listening on:

TNS-12560: TNS:protocol adapter error
TNS-00512: Address already in use
Linux Error: 98: Address already in use

Listener failed to start. See the error message(s) above...

Does anyone know how to make it work?

Thanks.
