Unable to connect to linux box w/ Exceed XDMCP broadcast

[ragnarok513]

Hi,

I am having trouble connecting to my Linux box using Exceed XDMCP Broadcast. I can see my server when I first start up Exceed, but after I get the login box, I am unable to type in my username into the box. I can fix this problem temporarily by rebooting the server, but then after a couple hours the username box will be greyed out again and I cannot type in my username.

I've called RedHat tech support and they don't offer tech support for XDMCP broadcast for my particular RedHat version (Enterprise WS). I've called Exceed tech support and they had no idea what was wrong with it. They've asked me to reboot the server but that only fixes it temporarily.

I've searched all over the internet for help and I could not find anything that would solve this problem. Here are some things that I've tried changing to my config files.


etc/inittab
change "id:3:initdefault:" to "id:5:initdefault:"
added this line "z:5:respawn:/usr/bin/gdm" to the very bottom


etc/X11/gdm/gdm.conf
under the [xdmcp] section I have..
Enable=1
HonorIndirect=0


etc/X11/xdm/xdm-config
I commented out the last line so it looks like..
! DisplayManager.requestPort: 0


etc/X11/xdm/Xaccess
In here, I uncommented this line
* #any host can get a login window


Those are all the changes I have made to my config files. I have tried every combination of those and I still would have this problem. Does anyone have a clue as to what's going on here? I appreciate any help I can get.

Thanks.

Can do you a direct query for the GDM server?

Also, take a look at the Kiosk howto - its what got me going on remote X terminals

How can I do a direct query to the GDM server? I can use SSH to get into my box but I'm not sure what a direct query is.

Your topic is about the Exceed XDMCP Broadcast (an icon in your exceed menu). When you clicker-de-click on Exceed XDMCP Query (another icon in the same exceed menu) you are promted for an ip address.
Fill the ip-number of you linux machine there and press "OK" (that is what ph34r means).

Then you know if "gdm" listens to the network or not.

N.B. Default it does not listen. Did you change gdm.conf?

When I enter the IP into the query, my Exceed application minimizes and nothing happens. The way that I've been getting into the server was that I would click on XDMCP broadcast, it would give me a list of servers to choose from to connect to, and my server would be part of this list. After choosing my server, I get a box prompting me for my username, but it won't allow me to type in my username. The text box is greyed out.

You can try this on your linux-box (I asume 192.168.0.1 for that machine):

go to a CUA tty (tty1 or tty2 or tty3....) and log on as normal user
type "X -query 192.168.0.1 -once :1"
now you should get a graphical login window, if not start fiddling around with your xdm/gdm/kdm configuration until it does.

Then go back to exceed....

What is a "CUA tty"? I can use SSH to log on there but that only gives me a command prompt. I'm not able to access the computer directly as it has no monitor, keyboard, or mouse.
