How to block access to database by IP address in Linux and Windows

IN LINUX: Solution: 1. [oracle@localhost ~]$ cd $ORACLE_HOME/network/admin 2. [oracle@localhost admin]$ 3. Edit the sqlnet.ora file similar way: 4. [oracle@localhost admin]$ cat sqlnet.ora # sqlnet.ora Network Configuration File: /u01/app/oracle/product/11.1.0/db_1/network/admin/sqlnet.ora # Generated by Oracle configuration tools. 5. Now Paste Following lines in sqlnet.ora NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT) tcp.validnode_checking = yes tcp.invited_nodes = (localhost, 192.168.11.22) tcp.excluded_nodes = (192.168.33.44) 6. save it [oracle@localhost admin]$ 6. Restart the listener. Now connection to your database from one of the IPs excluded will be prevented. Example: Trying to connect mysid Oracle db from ip 192.168.33.44: C:\>sqlplus myuser/...@mysid SQL*Plus: Release 11.2.0.1.0 Production on Copyright (c) 1982, 2010, Oracle. All rights reserved.
