[TriLUG] X sessions through SSH

[Henryk M. Kowalski]

I'm confused about a couple of points re: secure tunneling.

Scenario 1:
I'm running X locally.
I start xterm locally and SSH to remote host.
- So far the connection should be secure, i.e. everything typed in that 
xterm window is encrypted.

What happens if I start a detached terminal FROM the _original_ SSH 
terminal, i.e. I run 'xterm &' _on_ the remote host with the display 
automatically showing up on my _local_ X server?
  
I know that there is a key (.Xauthority) that's transmitted with the 
original SSH session setup to allow the connection from the remote host to 
the X server on my local machine, *but* is any of the communication 
encrypted by SSH?

Scenario 2: (Very similar)
I'm running a plain-vanilla X session locally and I just want this local 
machine to be a display (terminal) for a remote session, so I leave off 
any window manager.

I have xterm up (locally), and SSH to remote, then run 'startx' or 
equivalent _on the remote machine_ to get my window manager.

Am I correct in assuming that all of the traffic from this point on is NOT 
encrypted?  If so, is there a workaround?

Thanks,
