SSH & XFree86

[Harold L Hunt II]

John,

The Cygwin/XFree86 User's Guide explains a procedure that works for 
using SSH with X11 forwarding:

http://xfree86.cygwin.com/docs/ug/using-remote-apps.html#using-remote-apps-ssh


I wrote up some notes on why SSH fails for various reasons and how to 
avoid those failures:

Your particular failure seems to be that the DISPLAY variable is not 
defined when you run the ``ssh'' command.  I suspect that you are 
launching Cygwin/XFree86, but instead of running ssh from your xterm you 
are running ssh from another Cygwin bash shell that does not have 
DISPLAY defined.  Try running ssh from the xterm in Cygwin/XFree86 and I 
bet it will work.
