Help needed with TNS Listener on Solaris 2.4!!!

Hello, can anyone help, please:

when trying "$ lsnrctl start orasrv" (under Sun Solaris 2.4) I see:

TNSLSNR for SVR4: Version 2.2.3.0.0 - Production System parameter file is /var/opt/oracle/listener.ora Log messages written to /home/dba/oracle/network/log/orasrv.log Attempted to listen on:
(DESCRIPTION=(CONNECT_TIMEOUT=10)(ADDRESS=(PROTOCOL=IPC)
(KEY=Base1.world)))

TNS-12560: TNS:protocol adapter error
 TNS-00530: Protocol adapter error
  SVR4 Error: 80: Name not unique on network

Any ideas?

Thanks in advance!!

Dimitri.
