Re: Xvfb and X authorization

hi,
I have a script that opens Openoffice in an X session managed by
Xvfb.  I initiate the X session with: 

Xvfb :86 -screen scrn 800x600x32 &
This used to work fine.  But sometime in the recent past, presumably
since an unobserved update or something, I get this error when trying
to connect  

$ DISPLAY=:86 xterm &                              
[1] 18603
Xlib: connection to ":86.0" refused by server
Xlib: No protocol specified

xterm Xt error: Can't open display: :86
[1]+  Exit 1                  DISPLAY=:86 xterm -sl 1000
Xvfb itself generates this error:  
AUDIT: Tue Nov 16 14:37:43 2004: 18483 Xvfb: client 1 rejected from
local host

I can workaround this by invoking Xvfb with the -ac switch:  
Xvfb :86 -ac -screen scrn 800x600x32 & 

but obviously this is terrible security practice, so I can't use it
normally.  

I've flipped through the Xserver and Xsecurity man pages but I'm still
at a bit of a loss as to how to get Xvfb to read the authorization
file, or maybe I'm using the wrong one.  I tried this:  

Xvfb :86 -auth /home/matt/.Xauthority -screen scrn 800x600x32 &
just for the archive:  found the solution on the net, the file named by 
-auth should simply contain host names in cleartest.  In my case I made 
a file
/etc/X99.cfg
containing the single line:
localhost
and call Xvfb thus:
Xvfb :86 -auth /etc/X99.cfg -screen scrn 800x600x32 &

all fixed!
