So i have a running Ubuntu 14.04 Server on PowerKVM and was looking at exporting the display as there is no loacal X server running. The client i am using is Ubuntu 14.04 Desktop

so to do this i used the ' ssh -X Uname@serverip' and had checked the Display Var and it had been set but when i tried to run a GUI program it stated X11 connection rejected because of wrong authentication.

The steps i took to get to this point where:

Server side

1 disabled UFW

2 installed openssh-server

Client side

1 disabled UFW

2 Ran xhost +

after doing this i ran into the above issue X11 connection rejected because of wrong authentication.

to fix this i Did the following checking if it was working after each step

1 Check disk to make sure the is space df -H

2 Server side: i was the owner of Xauth, ls -l ~/.Xauthority

3 Server side chane owner and permissions

$ chown user:group ~/.Xauthority
$ chmod 0600 ~/.Xauthority

3 Server side: X11 fowarding was set to YES

$ grep X11Forwarding /etc/ssh/sshd_config

4 Client side: in the sshd_config file make sure

Host *
ForwardX11 yes

lines exsist

After these steps i had restarted the ssh connection ' ssh -X Uname@serverip' and checked the Display Var and then ran xclock as a test and it worked
