Can't connect with XDMCP - Invalid MIT-MAGIC-COOKIE-1 key

[Alexander Skwar]

Hi!

I've installed cygwin/xwin on my Windows XP machine so that I can connect
to other hosts using XDMCP; ie. I want to run XWin.exe -query host.

I'm succesfull in doing so when I'm connect to a certain part of the
company LAN network.  However, from another part of the network, I cannot.
 I'm trying to connect to HP-UX 11.00B workstations.  In /var/dt/Xerrors I get:

Xlib: connection to "0.0.0.0:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Xlib: connection to "0.0.0.0:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Xlib: connection to "0.0.0.0:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Xlib: connection to "0.0.0.0:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Xlib: connection to "0.0.0.0:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key

Wed Nov 27 08:47:46 2002
error (pid 4808): Server open attempt #0 failed for 0.0.0.0:0, giving up

At the same time, my XWin.log contains:

Fatal server error:
XDMCP fatal error: Session failed Session 6 failed for display 0.0.0.0:0:
Cannot open display

Any ideas about what I'm missing?  What's striking me, is that I'm able to
connect to the workstations from certain parts of our network with the
exact same setup - of course the IP adresses and routing is different.

Thanks a lot,

Alexander Skwar
