[ale] Running firefox remotely

[Jeff Lightner]

That is the way it is supposed to work.

The "X" in your "-CX2" enables X11 forwarding.  It is exactly what you
use if you want the display to come to you.

You use lower case "x" to disable X11 forwarding.

When you use the upper case X it sets the DISPLAY variable in such a way
that it comes back over your ssh session.   When you use lower case x it
explicitly tells it not to do that.

Try doing a simple "ssh -x cfowler at 192.168.1.112" then "echo $DISPLAY".
After that log out of the session and do "ssh -X cfowler at 192.168.1.112"
and then "echo $DISPLAY".   You'll see a difference.  You'll also see
the DISPLAY variable is NOT set to what you would expect for normal X
windows - that is because it is using the tunnel rather than the
standard port range in the 6000s.   (Of course all this assume you don't
have a bashrc, profile etc... that is explicitly setting DISPLAY=....)

Subject: [ale] Running firefox remotely

I ran into an interesting thing yesterday.  I guess it has to do with
Gnome. 

I loaded an old box with Ubuntu and I wanted to setup the firefox
plugins remotely. 

#1.  ssh -CX2 cfowler at 192.168.1.112 
#2.  xterm -bg black -fg white
#3.  firefox

What was strange was that I was expecting firefox to run on the remote
box and I get the display on my computer.  Instead firefox on my
computer ran instead!!

To do what I wanted to do I had to run Xnest.
