I'm having problems with running XWindows applications from one of my
machines. When I attempt to run a program from konsole, I get an error
message like this:

$ kwrite
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
kwrite: cannot connect to X server :0.0

I've never come across "MIT-MAGIC-COOKIE-1" before but a quick Google
revealed that it's an authentication scheme aimed at ensuring only authorised
people can access the X server. Furthermore, it uses a file in the home
directory, ~/.Xauthority , and I think this might be the problem.

I have 3 boxes, "box17", "box18" and "box20". box17 is a file server. User
"myuser"'s home directory, on all 3 machines, is box17:/export/users/myuser/
When I was just using box17 and box18, there were no problems, but now I am
using box20 with myuser, the problem has appeared. I am logged in with KDE
as myuser on both box18 and box20, and it seems likely that both are writing
to ~myuser/.Xauthority, which is stored on:

box17:/export/users/myuser/.Xauthority

and is therefore getting overwritten. In search for a was to turn X
authentication off, I tried xhost +, but got a similar error message:

$ xhost +
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
xhost: unable to open display ":0.0"

Is there any way to switch off X authentication, to get it to work? Or
is there another, simpler, way to get it to work?


(FWIW, I'm running Mandrake 9.1, and KDE 3.1)

you may need to edit the config files in /etc/ssh to enable X11
forwarding.
