Hi all,

I'm new to linux and am trying to work out a concept in my virtual machine. i'm unable to launch application in a remote server as a user using ssh x11 forwarding. With Root credentials i could.

Below is the message i get whn i try as a regular user.

*****************************************
[sean@localhost2 ~]$ ssh -Y root@server
root@server's password:
Warning: No xauth data; using fake authentication data for X11 forwarding.
Last login: Mon May 12 13:13:04 2014 from 192.168.159.134
[root@localhost ~]# firefox
Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyError: cannot open display: localhost:0.0

******************************************

When i try as root, I'm able to launch.

[root@localhost2 ~]# ssh -Y server
Last login: Mon May 12 14:16:52 2014 from 192.168.159.134
[root@localhost ~]# firefox
[root@localhost ~]#

Please advise guyz

Thank you for your reply EDDY1. My apologies as i totally forgot to mention in the thread that i referred this site (http://ubuntuforums.org/showthread.php?t=1525060) before posting.

X11 forwarding option is enabled in /etc/ssh/ssh_config

[root@localhost2 ~]# yum list | grep vnc

It works with root user credential and not with regular user meaning there is some configuration i need to check in user level.
