Open display error

[Jim Knoble]

Do you have X11Forwarding turned on in both /etc/sshd_config and
~/.ssh/config?  Try running both ssh and sshd in debug mode and see if
the output doesn't tell you something.

:  I get this message on the latest Debian potato for i386.
: 
: --> ssh -f localhost xterm
: sb at localhost's password: 
: --> xterm Xt error: Can't open display: 
: 
:  That happens also when connecting to another linux box:
: 
: --> ssh -f box2 /usr/X11R6/bin/xterm
: --> /usr/X11R6/bin/xterm Xt error: Can't open display: 
: 
:  The $DISPLAY is
:  :0.0 for box1
:  undefined for box2 after plain ssh connection
: 
:  If I manually set DISPLAY in box2 to box1:0.0 then I can open
:  all the windows I like, provided I ``xhost +'' box1. There are two
:  problems with this:
: 
: 1. box2 should set the DISPLAY by itself (how?)
: 2. I do not want to ``xhost +'' box1, as my email client (exmh) will
:    otherwise stop working.
