Has anyone got port forwarding to work with an oracle database?

I have OpenSSH 3.9p1 on my database server (Oracle 8i running Solaris 2.6) and my client is a PowerBook (running OSX 10.3.5) with OpenSSH 3.6p1 (I wish apple would update this) and when I try to set up the port forward the connection (using java thin client drivers) through it times out. Running the following from the client :

ssh -v -L 2521:dbserver:1521 user@dbserver

connects successfully and starts up a shell and then when I connect using the java thin client () I get :

this should do what your looking for,

ssh -v -L 2521:localhost:1521 user@dbserver

I'm assuming your using a dns name to resolve "dbserver". You don't want to send traffic back out to another possible host, just keep it on the localhost of the Host Server you are connecting to. If this is a question about allowing remote db software clients connect to the server then you might want to check your configs to see what needs to be changed to allow this behavior without tunneling (unless its exposed to the internet).
