The only other thing is make sure on the Network tab under the X-Config menu, that your display is the correct IP address.

This is the address you are telling the host to send the session back to. To determine the cause of the problem and resolve it, start with section A. Note: The troubleshooting steps in this note help you ensure that the XDM daemon is running and that Reflection X can successfully connect and run sessions using this daemon.

An alternate workaround for starting sessions is to manually start X sessions. Problem: Need to enable the xdmcp protocol in the Linux server for getting remote using XBrowser.

Most users installing Linux today choose to install and configure the X Windows System. This allows those users to access their Linux environment using a graphic GUI console connected to the workstation or server. An X Windows environment provides users to run X programs like xterm, OpenOffice, Mozilla Firefox and a host of other useful graphical software packages.

There are times, however, when users need to log in to a Linux machine using the graphical X Windows System from a remote computer, like a Windows PC for example. When installing Red Hat Enterprise Linux, the system defaults to a secure configuration which does not allow remote graphical logins or remote desktop access. A Linux environment allows for either a text login or a graphical GUI login.

Make certain the system is configured with the correct X11 runlevel which in this case is runlevel 5 :. Default runlevel. After starting the gdmsetup utility, click the Remote tab. Under the Remote tab, change the Style pull-down menu selection from 'Remote login disabled' to 'Same as Local':. Well, now that we've got everything basically working, all that we have left is to clean up the configuration of the chooser so it is a little more useable and visually pleasing.

The chooser can be configured using X resources. By changing these resources we can do things such as change the chooser fonts, the layout of the list, and the colors. Finally, we wanted to get rid of the default X11 "thatch" pattern on the root window, since it gives a horrid moire effect on small monitors.

To do this, we tell xdm to use a shell script, called "chooser. This script simply sets the background to "skyblue4" and runs the normal chooser. A lot more customization is possible, through both X resources and the XDM configuration scripts. Consult the xdm man page for more details. GDM will remember the user's choice and forward subsequent requests to the chosen manager.

Little is gained from the other schemes, and no effort has been made to implement them so far. Even though GDM tries to outsmart potential attackers, it is still advised that you block UDP port on your firewall unless you really need it.

GDM guards against DoS attacks, but the X protocol is still inherently insecure and should only be used in controlled environments. Even though your display is protected by cookies the XEvents and thus the keystrokes typed when entering passwords will still go over the wire in clear text. It is trivial to capture these. You should also be aware that cookies, if placed on an NFS mounted directory, are prone to eavesdropping too.

There are many different ways to login to a Linux computer. Most of them are text based and other graphical ones are slow and create lots of network traffic. To the windows click and pointy types the text based login's are a real pain and the other graphical types are murder over a slow connection.

What a lot of people have probably forgotten is that the Linux graphical system, XWindows, is a client server application and is as equally at home across the network as it is on a local machine. You have to change the runlevel to 5 to start X client on boot. Based on the desktop environment installed, you may have different display mangers.

You can use ps command to check which display manager is running:. First let's check how to enable xdmcp on GDM. Change the Style pull-down menu selection from 'Remote login disabled' to 'Same as Local'. FreeNX and x11vnc are good alternatives that feature more security.
