If the client requests X11 forwarding ("ssh -X yourserver") but $DISPLAY is not
defined after login, this usually means one of the following:

 - X forwarding is not enabled in the server's sshd_config.
 - xauth is not installed on either client or server.
 - xauth wasn't available (or not in the path) at build time and ssh or sshd
doesn't know where to find it.  (You can specify this with the XAuthLocation
option.)

> # xhost 64.xx.xx.xx
> # export DISPLAY=64.xx.xx.xx:10.0

sshd should set these automatically for you.  In general, if you need to fiddle
with these yourself then there's something wrong.

If none of those work, please attach (ie use "create attachment", don't paste
into the text field) the output of "ssh -X -vvv yourserver".
