How to prevent warnings like No xauth data when doing ssh from OS X to other machines?

Solution 1:

Put XAuthLocation=/opt/X11/bin/xauth in /etc/ssh/ssh_config.

I see it's an old question but for the sake of Google, here is my answer.

On the Mac, you can create an alias in ~/.bashrc like so:

alias ssh='ssh -o "XAuthLocation=/opt/X11/bin/xauth"'

If you also share the .bashrc across both OS X and other unixy machines, you could add a little stanza to the .bashrc as follows:

if [ `uname` == 'Darwin' ]; then
    alias ssh='ssh -o "XAuthLocation=/opt/X11/bin/xauth"'
