Can't export display to linux box

[subagon]

I admin lots of Unix servers (mostly Solaris) and need to export my display back to my Suse workstation using KDE.

Let me start with SSH is not an option.

Here what I've tried...

-> xhost + (duuuh)

-> Edited startx. Removed the line;

test "$DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN" != "yes" && serverargs="$serverargs -nolisten tcp"

-> Uncommeted the following line in /etc/services

x11 6000-6063/tcp X Window System

-> Edited /etc/X11/xdm/Xservers
from; :0 local /usr/X11R6/bin/X -nolisten tcp -br vt7
to: :0 local /usr/X11R6/bin/X -br vt7

-> Maked sure the link, /etc/opt/kde3/share/config/kdm/Xservers exists

-> Changed ServerArgsLocal=-nolisten tcp, to, ServerArgsLocal="" in /etc/opt/kde3/share/config/kdm/kdmrc

-> Restarted X

I'm going nuts. I've was able to get this working under Suse 9.2, but have upgraded to 9.3 and can't get it to work.

TIA,

Mike

I've also tried setting;

DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes"

in /etc/sysconfig/displaymanager without any luck.

[subagon]

Forget all the above. Just be sure the following is set. in etc/sysconfig/displaymanager

DISPLAYMANAGER_REMOTE_ACCESS="yes"
DISPLAYMANAGER_ROOT_LOGIN_REMOTE="yes"
DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes"

Uncommeted the following line in /etc/services
x11 6000-6063/tcp X Window System

Then reset X.

I was having the same problem, and thanks to your advice I fixed it right away after hours of beating my head on this!

For further reference for anyone interested, I found after further investigation
that at the minimum, there were only 2 changes necessary to make this work for my SuSE 9.3 box:

(1) DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes" in /etc/sysconfig/displaymanager

(2) remove (comment-out) the "ServerArgsLocal= -nolisten tcp" line in /etc/opt/kde3/share/config/kdm/kdmrc

I also un-commented the two "x11" lines in /etc/services just for form's sake (if I'm using the X service, these lines may as well be uncommented). But to my surprise, this didn't seem to affect my ability to connect to the X server one way or the other.

I also found the following files or parameters to be of interest, although not necessary to make any changes to these for things to work on my box:

in /etc/sysconfig/displaymanager:

DISPLAYMANAGER_ROOT_LOGIN_REMOTE
- this was necessary to connect to the X server, only if I had telnet-ed to the application machine (X client machine) from a root shell on the X server machine (the SuSE 9.3 box) (I didn't try exporting display from a root shell on the X client machine so I don't know if it affects this)

DISPLAYMANAGER_REMOTE_ACCESS
- this didn't seem to affect ability to connect to the X server, maybe it's for accessing the actual display manager (not the X server itself) remotely?

/opt/kde/share/config/kdm/kdmrc
- same file as /etc/opt/kde/share/config/kdm/kdmrc, but changes in this file didn't seem to affect anything. It must be just an installation copy for reference or re-configuration to defaults, not an actively-used config file.

/etc/X11/xdm/Xservers
- contains "-nolisten tcp" arguments, but didn't seem to matter, presumably becuase I am using kdm, not xdm. Perhaps it matters if using xdm.

/etc/X11/xinit/xserverrc
- consults the variable DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN in /etc/sysconfig/displaymanager and sets "-nolisten tcp" if "no". I would say one should never need to modify this file, but it's something useful to know about.

Hi all,

I have exactly the same problem in SuSe 10.0. I tried the actions that solved the problem for 9.3 but it didn't work.

Has anyone any idea about that??

Thanks

subagon, thanks SOOOO MUCH for the recipe - it almost worked on my SUSE 10.3.
And I wasted so many hours trying to figure this out....

The only thing that is missing in your post is the Firewall:
YaST -> Security -> Firewall
Allowed Services -> Remote Access to Display Manager -> Add
Advanced -> TCP Ports -> 6000

And voila! It is working now.

Always look in /var/log/messages. You will find usefull hints for this problems. In my case it was the firewall. My network card was defined as external.
