Setting XAuthLocation in the ssh_config doesn't help but should. Indeed
the path to xauth is hard coded:
bash-3.2$ strings /usr/bin/ssh |grep xauth
/usr/X11R6/bin/xauth
xauthlocation
No xauth program.
%s/xauthfile
Setting it on the command line doesn't work, either.
I used script to capture the output of ssh -vvv:
debug2: x11_get_proto: /opt/X11/bin/xauth -f /tmp/ssh-t4Ld83edOO/xauthfile
generate /tmp/launch-S8DVMZ/org.macosforge.xquartz:0 MIT-MAGIC-COOKIE-1
untrusted timeout 1200 2>/dev/null
So the right version of xauth is found.
Running that command at the command line fails (no such directory in /tmp, of
course). That error looks like this:
bash-3.2$ /opt/X11/bin/xauth -f /tmp/ssh-t4Ld83edOO/xauthfile generate
/tmp/launch-S8DVMZ/org.macosforge.xquartz:0 MIT-MAGIC-COOKIE-1 untrusted timeout
1200 2
/opt/X11/bin/xauth: error in locking authority file /tmp/ssh-t4Ld83edOO/xauthfile
Running ssh -Y will remove one of the two warnings. This remains:
Warning: No xauth data; using fake authentication data for X11 forwarding.
Running ssh -X leaves both warnings:
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Warning: No xauth data; using fake authentication data for X11 forwarding.
