vnc over an ssh tunnel Linux to Linux to Windows
I *think* what I want to do is not only possible but easy, but as a "dummy" 
I can't figure it out. Here's what I have:
I want to control the Windows computer from the Laptop via VNC, over the internet. I am already able to do this when the laptop is at home, but I'd like to also do this when away from home as well. I have heard rumblings that I can, through some trickery with SSH, piggyback a connection from the laptop, to the linux computer, and then get to the Windows computer, but other than being able to describe it (if I'm even able to do that. Let me know if any of this is confusing) I can't even start to think about HOW to do it.
Also, if there's an easier (yet still secure) way to do this, by all means I'm willing to learn.
I can't figure it out. Here's what I have:- Linux (Ubuntu 10.04) laptop that is not in my house, but has an Internet connection.
- Linux (Ubuntu 9.04) computer in my house that has unfettered access to the internet. I can (and do, frequently) ssh to from the outside world.
- Windows (XP) computer that is on the network with the Linux computer, but not set up to accept any connections from outside as I'm a little overly security minded.
Also, if there's an easier (yet still secure) way to do this, by all means I'm willing to learn.
