Help desperately needed...
 

Good morning all,

Okay, I have to get this workign this week still so please any help out there will be appreciated!

I have a very of RD server with a customized kernel, whihc is why the version is so old it is RH 7.3. This is running a veru complexed MIS applaiction/database.
What I am trying to do is get a Centos 3.3 box to connect to it and display a login screen to that server so that I can run the application that way.

What I have been told so far is to edit the /etc/inittab file and do the following:
old:
# Run xdm in runlevel 5
# xdm is now a separate service
x:5:respawn:/etc/X11/prefdm -nodaemon

new:
# Run xdm in runlevel 5
# xdm is now a separate service
x:5:respawn:/usr/X11R6/bin/X -once -query 192.168.XXX.XXX

After a reboot the server will display the Login screen of the server.

Well if I do this, it comes up with a blank screen displaying the X.
I have checked on both machines the xfs service is runnign and with my "HUGE" knowldege on Linux everything seems to be in place.

The funny thing is that when I used Fedora, it worked first itme? Does it mean there might be some files that are the saem between fedora and rh 7.3 which has changed with Centos 3.3 or that Centos 3.3. is nto compatible or able to display apps/screens/graphics from a RH7.3 with customized kernel?

Okay, now I am gettign a different error that might help the experts direct me in the right direction to fix this problem:

When I go to the screen it shows at the bottom the following:

(==)Using config file:"/etc/X11/XF86Config"
XDM:too many retransmissions

any ideas?????:confused: :confused: :confused: :mad:

One thing to consider is to start the application on the Centos box using SSH instead of running another X-windows session on the server. This way, you could have a more recent KDE or GNOME session running on the Centos box while running a lightweight window manager on the server.

The x-windows traffic will be to display the application rather than an entire session.

Also, this method may be more secure.

Your response makes perfect sense but :newbie: I just have one major question for you.......how do you do this so that when the user logs in it automatically stars the app and give them no choice of doing anything else on this box except loggin into this app??? Sorry if it is a stupid question but it is my first time....:p :p

Xwindow display error
 

>>Well if I do this, it comes up with a blank screen displaying the X.
..Sounds like a working instance of the default window manager.
In some situations this is a blissful sight.

Were you unable to open a terminal there?

I can get to a terminal but not from the GUI......by typing Ctrl Alt F1
Is there anybody out there that can tell me why this is not workign for me???

OK, switch to runlevel 3, and try running 'redhat-config-xfree86'.

I've done that before but it still didn't solve the problem, if I do run 'redhat-config-xfree86' what am I suppose to change or edit?

To comment the X query lines anything may be mentioned in /etc/rc.d/rc.local file. Then reboot the system.

Okay, this is drivign me batty now!!!!!!
There is nothign in the rc.local file.....

All I want to do is get a Centos box as a workstation running an app from a RH 7.3 , with special kernel thus the reason for old version.....nothign else...
Please please someone help?????:cry: :cry: :cry:

OK....
the inittab file has this configuration now:

#Run xdm in runlevel 5
#xdm is now a seperate service
x:5:respawn:/usr/X11R6/bin/X -once -query 192.168.0.200

Once the system is rebooted it comes up with this error:
INIT: Id "x" respawning too fast: disabled for 5 minutes


ANY IDEAS MASTER???

Is the xserver local or remote?

Okay, had a look at the article and you had my hopes p there when I saw the title...:(
Anyway, the server is local to the network, if that is what you mean?
Maybe this will give you a better picture:
I have an MIS server on IP 192.168.0.200 and have this client work station that I need to run an application from the MIS server i.e. a dum terminal with minimum installed. This box wil be used in the production area to capture time.
Now the engineers who put the MIS server together said all I need to do is add the line in the inittab file of the workstation and it should work, now they in Germany and I am in Sout Africa, a bit difficcult getting them out here for somethign this small.

The "x" in my error does nto have a number it says X........I don't kwno which way to go anymore???:cry: :cry: :confused: :confused: :mad: :mad:

By 'local' I meant host not network, should have been more specific. I am asking relative to firewalls, the client and server are on remote hosts and there may be one or more firewalls between them. ergo: Could a firewall be preventing the client from reaching the server.

I've caused this error by mistake several times in class, but can't recall what I did to cause it. Will try to replicate here.
