Well, more to the point for me... why does this happen? It
certainly
shouldn't, and I've done everything I can to eliminate the message.
You can't eliminate it, I suspect.
ssh is running the command
xauth list $DISPLAY (e.g. xauth list /tmp/launch-blah/:0)
and xauth is generating the output
xauth: (argv):1: bad display name "/tmp/launch-blah/:0" in "list"
command
I'm not quite sure what the "fix" here is, since the Xauth data
probably
isn't generated until the X server starts, which won't happen until
sshd
requests that the forwarding happen -- and I think that may be
after the
authentication data is transmitted to sshd.
Perhaps best would be to simply disable the warning in sshd for
Darwin....
... or teach xauth about the weird new display names.
Here is a little patch against xauth-X11R7.2-1.0.2 from X11apps-13
that
does this. As before, the warning will only disappear if there is an
existing ~/.Xauthority file.
Neat; I thought this'd have to be patched in ssh. Thanks!
