Description larson 2000-06-01 09:30:00 UTC

The man page says X11 forwarding is requested when DISPLAY is set
on the originating system.  It is apparently not so, as -X needs
to be set as well in the originating command.

This might be related to the defaulting of X11 to disabled in sshd
referred to in a previous bug report, in that someone turned them
both off, but why?

How-To-Repeat: verify DISPLAY set to your display

Hi

From ssh(1) on a 4.1-Stable

"Forwarding of X11 connections weakens the security of ssh and is 
disabled by default.  X11 forwarding can be enabled on the command line
or in configuration files."

Hence you need to uncomment 
#   ForwardX11 yes
in the ssh_config file (in /etc/ssh for 4.2-stable with OpenSSH).
