X-Window System Protocol

 The X Window System Protocol, also known as X Window or X

Protocol, is a graphics architecture used as the graphical system

on Unix systems (primarily) and Linux systems

 X Window System (X Protocol) provides an inherently client/server

oriented base for displaying windowed graphics

 It manage a video system including "interactive" I/O devices such

as mice, keyboards, and some more unusual devices

 X Window System (X Protocol) has two primary versions: X10 and

X11

X Window Display Manager

 XDM (in full, the X Window Display

Manager) is the default display manager

for the X Window System It is a

bare-bones X display manager

 It was introduced with X11 Release 3 in October 1988, to support the standalone

X terminals that were just coming onto the market

 It was written by Keith Packard.

GNOME Display Manager

 GDM (the GNOME Display Manager) provides a

simpler alternative display manager for the X Window System's XDM.

 GDM allows users to customize or troubleshoot settings without having to resort to a command line Users can pick their session type on a per-login basis

 GDM also features easy customization with themes.

X Display Manager Protocol

 XDMCP stands for "X Display Manager Control Protocol" and is a network protocol

 It provides a way of running the X-Terminal to run on your PC (or MAC) and it uses the X Server to provide a client/server interface between display hardware (the mouse, keyboard, and video displays) and the desktop environment while also providing both the windowing infrastructure and a standardized application interface (quoted from XFree86 Project home page)

 The X-Terminal can be displayed with an individual window or multiple windows, based on your X window system's software capabilities and setup

XDMCP & Gnome Display Manager (GDM)

 GDM also supports the X Display Manager Protocol (XDMCP) for managing remote displays

 GDM listens to UDP port 177 and will respond to QUERY and BROADCAST_QUERY requests by sending a WILLING packet to the originator

 GDM can also be configured to honor INDIRECT queries and present a host chooser to the remote display

 GDM will remember the user's choice and forward subsequent requests to the chosen manager

 Since it is fairly easy to do denial of service attacks on the XDMCP service, GDM incorporates a few features to guard against attacks

Enable XDMCP on redhat

 In Red Hat® Enterprise Linux® 4 and below the file /etc/X11/gdm/gdm.conf could be modified to enable xdmcp With Red Hat Enterprise Linux 5, the location to enable xdmcp has changed.

 There are two ways that xdmcp can be enabled:

 Modify the file /etc/gdm/custom.conf and under the [xdmcp] section, add this line: Enable=true

 Alternately, the tool gdmsetup can be used This is a gui-based tool to modify gdm

 Once one of these two steps are done – simply run gdm-restart and then login as desired user.
