[TriLUG] question 2: ssh tunneling with putty

[gregbrown at mindspring.com]

Quesion:

As long as I ssh into my box over the Internet is EVERYTHING related to that shell encrypted as well?  Let me attempt to clarify.. 

if I ssh into my box I assume my login and password are sent to my server encrypted.

If I execute a command.. say xclock is all that X traffic coming back to my local machine from my server encrypted as well?  

What about if I redirect my display after ssh'ing in then start another xterm?  Is the encryption inherited to that new shell which started when I executed the xterm & command?
