I have been having problems recently while trying to ssh into linux servers (Ubuntu 14.04) from my mac (OSX Yosemite 10.10). This used to work fine until my latest update, where I systematically get a "X11 connection rejected because of wrong authentication".
The problem seems to be on the client side, as I can use X forwarding just fine from another mac with the same setting as far as I know. I tried to reinstall the latest XQuartz version but the problem remains unchanged. I also tried to change /etc/ssh_config to add "X11Forwarding yes", but without a visible change either
Any idea as where I should be looking to solve my problem? Thanks a lot for your help.
