Every time I initiate an ssh connection from my Mac to a Linux (Debian) I do get this warning:
No xauth data; using fake authentication data for X11 forwarding.
This also happens for tools that are using ssh, like git or mercurial.
I just want to make a local change to my system in order to prevent this from appearing.
Note: I do have X11 server (XQuartz 2.7.3 (xorg-server 1.12.4)) on my Mac OS X (10.8.1) and it is working properly, I can successfully start clock locally or remotely.
