can not connect to oracle database with ip address

Question

I am new to oracle database, I have installed Oracle 11.g on redhat 5.6, I have a database that I can connect to it using the following command:

export ORACLE_SID=test
sqlplus user/passwd

but not connect to database neither remotely nor from localhost: sqlplus user/passwd@myhost:1521/test error: ORA-12541: TNS: no listener

this is my listener.ora file:

# listener.ora Network Configuration File: 
/Oracle/oracle_base/product/11.2.0.4/database/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
 (DESCRIPTION_LIST =
 (DESCRIPTION =
 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1522))
 )
 )
ADR_BASE_LISTENER = /Oracle/oracle_base

this inside tnsnames.ora file:

test =
 (DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
 )
 (CONNECT_DATA =
 (SERVICE_NAME = test)
 )
 )

and this is output of lsnrctl status is:

Answer 1

Listener listens on port 1522, but you are trying to connect port 1521. Update your tnsnames.ora with the correct port number (1522).
