Getting Cygin/x-win32 To Work With Gentoox, I get an "c

[viper1024768]

Hi All,

Has anyone been able to create a remote X session with Gentoox? I've followed the tutorial written here : http://forums.xbox-scene.com/index.php? ... l=slainand however, I get an error saying that the display cannot be open.

I can log in via SSH, but I just can't get anything to transfer over to the X-Win32 or CyGen window.

Typed startkde ....and this is the response I get:

xset : unable to open display ""
xsetroot: unable to open display ' '
startkde: Starting up...
ksplash: cannot connect to X server etc etc

This is how my sshd_config looks like:

# $OpenBSD: sshd_config,v 1.65 2003/08/28 12:54:34 markus Exp $

Any help is greatly appreciated.

I think you need to add your Xserver to the allowed list (where "XSERVERHOST" is the IP/hostname of your X client)...

# DISPLAY=XSERVERHOST:0.0
# export DISPLAY
# xhost XSERVERHOST
# xterm

You should get an xterm appear on your client Xserver. Works for me, anyway.

Those settings will allow him to directly connect to his box, but that won't use SSH tunneling, like he's asking. When you use X11 tunneling with SSH (make sure you tell your ssh client to tunnel x11 connections), it should tunnel display connection made to an offset shown in the config file (or default, if it's not used). As below, this is from your config file:

X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes

X11 Forwarding is enabled and it's defaulted to offset 10 and localhost. When you log into your box, type "export DISPLAY=localhost:10". That should tell xwindows to forward display connections to offset 10 which SSH will forward through to your connected machine. Also make sure that there's X-Win32 or something similar running on your windows machine. You may also need to add "127.0.0.1" to the "xhost list" in the security tab of xconfig for X-Win32 to allow the connection.

I have xwindows running on my xbox and when I ssh in and set the display variable I can run things like "xeyes" and they pop up fine.
