Create an SSH Tunnel to a Node with PuTTY
If a resource provided by an Oracle Java Cloud Service node uses a port that is not directly accessible through the Internet, you can access that resource by creating a secure shell (SSH) tunnel to the port. You can create an SSH tunnel from a Windows platform by using PuTTY, an open source networking client.
In general, an SSH tunnel can map a remote port to any available port number on your local computer. Some protocols, such as Java Remote Method Invocation (RMI), require that the remote and local port numbers be the same value.
To download PuTTY, go to http://www.putty.org/.
Applications that are running on your local computer can now communicate with the node by using localhost:port
, where port
is the local port number.
After your work with the SSH tunnel is completed, press Ctrl+C to close the SSH tunnel.
