Encrypting network communication using SSH tunneling
In these days ssh is the de facto method for establishing a remote connection to a host. It can also be used to tunnel and encrypt network communication between two hosts. SSH tunneling can be implemented for encrypting network communication between a computer used by a DBA for remote database administration, but is also suitable to be used with Data Guard for encrypting log shipping. In this recipe we will encrypt the network communication between nodeorcl1 and nodeorcl5 using ssh.
