[tlug] Forwarding X and SSH

["Jim O'Connell" <oconnell@example.com>]

Hi all - 
The other day I discovered forwarding X by accident - 
I was logged in over ssh to my office from home, using an X-term.  Out of habit, I typed 'sylpheed &' to start up my mail and was quite surprised to see my *work* account pop up, instead of my home account.  (Did I just hear 100 veteran TLUGgers say "Well, duhhh!"?)
I knew that you could forward X programs, but thought you had to set some display variables and frankly I never had a use for it before.
Anyway, my question is this: If I open up a remote program while using SSH, is the entire program being transmitted in an encrypted fashion, or is it spawning a non-encrypted X session? (In which case, I better take a look at what my firewall isn't doing right...)
Cheers,
Jim
