[SOLVED] How to export the display

[ursusca]

Hi everyone,

I use KDE desktop (3.5.10) on my Gentoo computer. I'd like to run remote applications on my computer.

For clarity, lets say the box that I want to export X from is named A(CentOS) and the one want it to go to is named B(Gentoo).

B:
mike@gentoobear ~ $ xhost +192.168.1.2
192.168.1.2 being added to access control list
mike@gentoobear ~ $ ssh 192.168.1.2
A:
[mike@bearcentos ~]$ DISPLAY=192.168.1.7:0.0; export DISPLAY
[mike@bearcentos ~]$ echo $DISPLAY
192.168.1.7:0.0
[mike@bearcentos ~]$ xterm
xterm Xt error: Can't open display: 192.168.1.7:0.0

why this is happening...

What elese do I need to do?

Try

export DISPLAY 192.168.1.2:0.0

EDIT: maybe I'm confused to which IP you want, you might want 192.168.1.7:0.0 instead. Try different variations if it doesn't work right.

I want export display from my centos computer (192.168.1.2) to my gentoo computer (192.168.1.7). I've tried from gentoo to centos ang it's OK. But I need to export display from centos to gentoo.

I generally tunnel over ssh. I connect to the remote box using ssh -X and then any applications I launch from that ssh session - including an entire desktop session - will open on my local machine. Is that any help to you?

I am trying to do it over xdmcp. Not over X11 forwading.

I've tried to do it over X11 forwarding.

I've checked the following line in my /etc/ssh/sshd_config file:

X11Forwarding yes


B:
mike@gentoobear ~ $ xhost +
access control disabled, clients can connect from any host
mike@gentoobear ~ $ ssh -X 192.168.1.2
mike@192.168.1.2's password:
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Warning: No xauth data; using fake authentication data for X11 forwarding.

[mike@bearcentos ~]$ xterm &

[mike@bearcentos ~]$ firefox &

[1] Done xterm
[mike@bearcentos ~]$

It works for me but can anybody explain me what dies it mean:
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Warning: No xauth data; using fake authentication data for X11 forwarding.
