If you've tried running exmh, then you've probably come
across these infamous xauth errors:
BgRegister X server insecure (must use xauth-style
authorization); command ignored
exmh-bg cannot rendez-vous with UI - exiting.
Usually this is because Tk send is not working.
Check the notes under Frequently Asked Questions #4a and
You can find this under the Help menu.
The problem is that there is a missing directory that needs
to be created.
If you're using operating in runlevel 5 you can look at your
/var/log/xdm-error.log file and you will notice that the
first line should look like this:
xdm error (pid 491): Cannot open server authorization file
The directory that needs to be created is
After this is created, xauth takes over and everything is
FWIW, this problem has persisted since XFree86-3.3.2 (at
err... that should be /usr/X11R6/lib/X11/xdm/authdir/authfiles

localhost kdm: Cannot open server authorization file

After installation of RH60, when rebooting the system for
the first time, this message appear in the log file
/var/log/messages "could not create dir /etc/X11/fs/.xauth"
This is a new install and the /etc/X11/fs exist with the
file config. It doesn't cause problems with my XFree86 but I
can see the message (could not create dir
/etc/X11/fs/.xauth) in the log file. I think that the system
cant create the file in the directory because
it doesn't have permission to do, the /etc/X11/fs is 755 by
default when your install Linux for the first time. If I
change the permission of this folder for 775 it's work
but am not sure if it can by a problem with the security of
the system? Strange. xfs is run by the xfs user, which of
course does not have root priviledges, but /etc/X11/fs is
owned by root.root. Why enabling write permission for the
root group makes the error go away makes no sense because
xfs's group is xfs.

This will be fixed in an upcoming errata release of X.
*** Bug 2914 has been marked as a duplicate of this bug. ***
When using [kx]dm as prefdm (/etc/X11/prefdm) the directory
/etc/X11/xdm/authdir does not exists, in which case the dm
-failing to store xauth cookies- falls back to using xhost
Any user on the system can now grab whatever display (either
local or remote) has logged into the system, and wreck
If not sure type xhost at an xterm to check for security. If
(etc.), your authdir does not exist.
Create it now, or fear the laughter of your colleages
(filling your screen with garbage) :).

This doesn t seem to happen with the alpha distrib ...
(shouldn t they all come from the same .src, BTW ? or this is due
do different SPECS files ?)
But I confirm it on i386...
The problem I have now, is that I canot xhost -localhost or xhost
-Mylocdispname ... the command pass silently but tese entries remain
in the list !

We will soon be putting out an errata release of X that explicitly
packages the authdir. Under some (unexplored) circumstances, xdm will
create the directory for itself, but we cannot rely on this happening.
Thank you for the report.
Fixed in errata XFree86-*-52 release.
