Oracle on VM Workstation

Hi

I'm using vmware workstation 5.5.5 to try and learn Oracle 11g. Oracle is successfully installed on my laptop under RH Linux and I would like to connect to it using the client tools installed on my laptop. However I can't get it to talk to it. Anyone know what to do. I've tried using localhost and Microsoft loop back adapter but with no luck Image may be NSFW.
Clik here to view.

thanks
