Hello,

The server : FreeBSD 7.0 (without screen) on which i install :
/usr/ports/x11/xauth
/usr/ports/x11-fonts/xorg-fonts
/usr/ports/x11/xhost
/usr/ports/x11/xdm

The configuration file on the server ssh /etc/ssh/sshd_config
AllowTcpForwarding yes
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes
The configuration file for the client ssh /etc/ssh_config ( depends with the client )
Host *
ForwardX11 yes

The client machine :
- WinXP with Cygwin+Package X ( application X work well ).
soit un powerbook sous MacOS X 10.4.11 ( application X work well with XDarwin).

from one the client machine
ssh XX.XX.XX.XX -l user -X
export DISPLAY=localhost:10.0
xeyes &
X connection to localhost:10.0 broken (explicit kill or server shutdown).

so :
xauth list
xauth: creating new authority file /home/user/.Xauthority
No file /home/user/.Xauthority
xauth generate localhost:10.0 .
xauth: creating new authority file /home/user/.Xauthority
X connection to localhost:10.0 broken (explicit kill or server shutdown).
and 2 files
.Xauthority-c ( empty )
.Xauthority-l ( empty )

so i try another way :
xhost +localhost
X connection to localhost:10.0 broken (explicit kill or server shutdown).
su
xhost +localhost
X connection to localhost:10.0 broken (explicit kill or server shutdown).

I look in the log file, look for on the net and do not find my mistake.

Has anyone an idea ?

Thanks

Jeannot

Also by default the X server doesn't open the port to allow X connections, this has to be done when loading the X server:

http://www.x.org/archive/X11R6.9.0/doc/html/Xserver.1.html

need to remove the option so X listens on port 6000 or else this wont work obviosuly. By default the option -nolisten tcp is used
