I installed 11g on Centos VM on my mac.I have everything up and working on server.I have included following command I ran on cenos.

My tnsnames.ora file is as follows:
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora # Generated by Oracle configuration tools. LISTENER_ORCL = (ADDRESS = (PROTOCOL = TCP)(HOST = hayer)(PORT = 1522)) ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = hayer)(PORT = 1522)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) (SID = orcl) ) ) ~ ~ ~ ~
On Centos server I can log in using sqlplus too. I changed tnsnames.ora on windows to same as server.I have added oracle host information in windows host file and I can ping oracle host and telnet host on port 1522.
I have disables service iptables so no type of firewall exists on centos.
But I still get following error on Windows client:
