ssh (was: web based)

[John G Heim]

The -x flag means that after you log into the remote server, you can run 
X11 apps on the remote machine and have the display appear on your local 
machine.  X11 works by sending instructions to the X11 server on your 
local machine. So when you run an X11 program locally, it's talking to a 
server, an X11 server, on your local machine. The -x flag tells ssh to 
forward those X11 instructions from the remote machine back to the X11 
server on your local machine. Obviously, for this to work, you have to 
have an X11 server running on your local machine.  Those do exist for 
Windows but I know nothing about them. The remote ssh server also has to 
have X11 forwarding enabled.
