I just installed Oracle 11g XE on Oracle Linux 6. I just want to connect to this database from a Windows computer using Oracle SQL Developer. I've set up my Connection in SQL developer as follows:
Username: system
Password: <password>
ConnectionType: Basic
Role: default
Hostname: 192.168.1.104 (the address of the Oracle Linux machine)
Port: 1521
SID: XE
When I click "Test", the error comes up: "IO Error: The Network Adapter could not establish the connection. Vendor code 17002".
Below I have supplied a bunch of relevant information about the Oracle XE server. Please help me to figure out what is wrong. Thanks in advance for any advice you can offer.
