Problem:
X authentication using MIT-MAGIC-COOKIE-1 fails but
xhost based
authentication is working.
Setup:
XWin on Windows XP Professional, X client from Redhat
8.0
Version:
CYGWIN_NT-5.1 MYMACHINE 1.5.9(0.112/4/2) 2004-03-18
23:05 i686
unknown unknown Cygwin
Commandline:
XWin -audit 4 -fullscreen -clipboard -auth
C:\myhome\authfile
ServerOutput:
AUDIT: Wed Apr 28 11:05:53 2004: 3132 XWin: client 1
rejected from IP xxx.xxx.xxx.xxx port 39784
Auth name: MIT-MAGIC-COOKIE-1 ID: -1
winProcEstablishConnection - ProcEstablishConnection
failed, bailing.
AUDIT: Wed Apr 28 11:05:53 2004: 3132 XWin: client 1
disconnected
ClientOutput:
Xlib: connection to "mymachine:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Error: Can't open display: mymachine:0
Using FileMonitor from sysinternals I found that XWin
NEVER reads the
authfile that I specify on the command line. How does
XWin gets the cookies
if it never reads the file? I am not sure whether this
is the error I may
be wrong. I have included only the relevant output.

There should be atleast one READ in the 3rd column
right? I do see READ for
other files that XWin uses. Thanks for any help.
