how to access Apple Remote Desktop (ARD) via VNC-over-SSH? I've done a bit of research and it seems ARD is somewhat based on VNC technology. It even has the option to allow access via VNC viewers using a password.

I want to enable this option so I can interact with my mac pro when needed. But I'm wary of the security.

I've use VNC-over-SSH in the past but with other OSes like FreeBSD and Linux. I'm wondering if something like this is feasible on OSX using built-in features.

I've searched the net but didn't find what I'm looking for.

Thanks a lot :)
So you can.  If you open System Preferences > Sharing, and check both remote management (to start the vnc server) and remote login (to start the ssh server); you should be able to login remotely using vnc over ssh.

Note: You must have all needed ports forwarded correctly, and an android client capable of connecting over ssh.
