[SSI-users] Starting X applications in loadlevel.conf

[Miguel B. C. <dir...@ci...>]

Hello, I posted this message in the developer list, the past night, I
think that it's a interest thing to resolv : 

Hello, I am trying to loadleveling with mozilla, gftp ...etc. For this
I try to execute: 
        onnode 2 gftp 
        but it returns :
        (gftp-gtk:69038): Gtk-WARNING **: cannot open display:

        or

        x11drv: Can't open display: :0.0
        Please ensure that your X server is running and that $DISPLAY
is        set
correctly.

        I make all the changes in /etc/inittab and
/etc/security/console.perm ,
but I still have the same problem...

        some hint?

        Regards,

        PD: I am using a 'clean' Red Hat 9.

        Bye! Miguel.

The answer of John Hughes was:

The problem is that $DISPLAY is :0.0, so the application uses the socket
/tmp/.X11-unix/X0 to talk to X.  But by doing "onnode 2" you have a 
different /tmp:

$ onall ls -li /tmp/.X11-unix/X0
(node 1)
 391098 srwxrwxrwx    1 root     root            0 2004-06-01 14:19 
/tmp/.X11-unix/X0
(node 3)
 715448 srwxrwxrwx    1 root     root            0 2004-06-03 18:34 
/tmp/.X11-unix/X0

So you're trying to talk to the wrong X.

You can do it by telling X to use TCP.  But you'll have a pretty hard 
time getting the authorisation right.

(I tried to work around this making /tmp/.X11-unix a non-CDSL, and 
giving each node it's own display number, but I had huge problems with 
authorisation, X didn't like "local" access from a machine with a 
different hostname).

Excuse me from cross-over the mailing list...
