X11 connection rejected because of wrong authentication
584868Jul 27 2007 — edited Jul 27 2007When trying to install Database 10g in Linux as the "oracle" user via SSH, I get the following error:
X11 connection rejected because of wrong authentication.
X connection to localhost:10.0 broken (explicit kill or server shutdown).
I have tried the following remedies with no positive results:
* Issued "xhost +" as root. This command completes successfully, but it does not seem to have any effect on the problem for the "oracle" user.
* Logged in remotely with the "ssh -X" flag as the "oracle" user. Again, no problems with that, but the error persists when I run the installer or any X applications.
* Added the value "X11Forwarding yes" to /etc/ssh/sshd_config
* Added the value "ForwardX11 yes" to /etc/ssh/ssh_config
* Added the value "DisallowTCP=false" to /etc/X11/gdm/gdm.conf
I'm not sure what else to try.
I searched for this error phrase in the forums, and I was very surprised not to find it. It seems like a common installation error among Linux users/admins.
