If you are trying to start the listener and are runing into the message below:
###############################################
TNSLSNR for Linux: Version 11.2.0.1.0 - Production
System parameter file is /u01/app/oracle/product/11.2.0/db11g/network/admin/list ener.ora
Log messages written to /u01/app/oracle/diag/tnslsnr/dbms/listener/alert/log.xml
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dbms.f2c.com.br)(P ORT=1521)))
TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
###############################################
Then , rename your sqlnet.ora, listener.ora and create another listener using netca or netmgr an try again.
This should solve your problem.
