I searched and found threads on this topic but I can not get the
warning message to go away using what the threads say to do.
If I am in Terminal or an xterm, my DISPLAY is set to something like /
tmp/launch-sf4x/:0
This is not in .Xauthority. So, if I do something like "ssh -f -Y
remotehost xterm" I get back:
Warning: No xauth data; using fake authentication data for X11
forwarding.
Everything else seems to work fine. And I've read about the cute
trick that accessing this socket causes launchd to start up, etc. But
ssh is still unhappy.
I have discovered that if I change my display (after X11 is running)
to :0, then I do not get the message from ssh.
I kinda want to open a bug report with Apple but wanted to bounce my
idea off of this list first.
Could ssh be hacked so that it basically does this for me? i.e. check
DISPLAY. If it is set to /tmp/launch.*/:0, then do a cat of the file
(or open it or whatever is required), set the DISPLAY to :0, and
continue normally.
The alternative I suppose would be to allow me to do:
xauth generate $DISPLAY .
but, currently, xauth complains that $DISPLAY is not a valid display.
I created this script and I have it in my ~/bin directory (which is
part of my PATH). It seems to avoid the warning message.
#!/bin/sh
if [[ "$DISPLAY" =~ /tmp/launch-.*/:0 ]] ; then
cat "$DISPLAY"
DISPLAY=:0
fi
exec /usr/bin/ssh "$@"
