SSH X windows error message


SSH X windows pipe is successful in displaying a calculator first time out,
not satisfied by this I am curious to know what this error message is trying to
tell me.
** (gcalctool:3556): WARNING **: Couldn't connect to accessibility bus:
Failed to connect to socket /tmp/dbus-N0iPOOmrtg: Connection refused
Can you give me a clue?

EDITED /etc/X11/xinit/xserverrc
exec /usr/bin/X "$@"
EDITED /etc/lightdm/lightdm.conf.d/10-xubuntu.conf
xserver-allow-tcp=true
REBOOT
COMMAND
sudo xhost+ 192.168.1.200 {I now reolise this is not needed for access via SSH tunnel, sudo xhost -, makes no difference}
On remote Ubuntu 14.04 Server + gnome-core xfce4 firefox & Static IP
EDIT /etc/ssh/ssh_config
X11Forward yes
sudo service ssh restart
On local Xubuntu 14.04
COMMAND ssh -X <name>@192.168.1.200 -p <port>
COMMAND gnome-calculator
Hey presto the calculator appears but in the terminal it is telling me it has failed?

for xhost you should not use sudo, that can only work without that.
from the other hand please post the exact error message

Hi, xhost configuration works fine with or without "sudo" however I now realise that it is not necessary when using an SSH Tunnel so I have reversed all the Xserver configuration but the error message is just the same as it was in my first post, apart from the port and reference numbers:

** (gcalctool:8391): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-Qx25wN5my7: Connection refused

And "gcalctool" the gnome calculator appears every time, this tool is not installed on my laptop so I am sure its origin is on the Ubuntu computer.

The gnome runtime is trying to connect to your (remote) dbus session. It can't.

It is just another non-portable thing gnome keeps doing that breaks remote window services.

Now, it appears that the application is working, and this isn't critical; as a warning it can be ignored and is just noise.

The gnome developers keep assuming that only local windows are used.
