reflection on linux

Configuration of the XDMCP on RedHat 9

Introduction
This procedure is intended for enabling XDMCP communication allowing to use a remote X Session from a Windoze machine to a Linux Server. In this case, Reflection will be the client software.

Step 0
be sure that:
Linux Server is up
Have the right account information
Linux Server is reachable from your client machine (ping)
X is up
That you are logged-in at
Step 1
Edit file: /etc/rc.d/init.d/xfs
Change: daemon xfs -droppriv –daemon
For: daemon xfs -droppriv -daemon -port 7100
Step 2
Edit file: /etc/X11/fs/config
Comment out the “no-listen” line by putting a “#” character at the beginning
Step 3
Type: /sbin/service xfs restart
Step 4
Edit file: /etc/X11/xdm/xdm-config
Comment out the "DisplayManager.requestPort: 0" by placing a ! before it
Step 5
Edit file: /etc/X11/xdm/Xaccess
Uncomment out the line by removing the # at the beginning of the line:
From: # * #any host can get a login window
To: * #any host can get a login window
Step 6
Edit file: /etc/X11/gdm/gdm.conf
Change: "Enable=false" in the [xdmcp] section
For "Enable=true"
