Step by Step on how to connect to coLinux using VNC with XDM authentication

I am using coLinux on a Windows XP Pro box with Debian installed.

After doing these changes you will be able to connect by one of the following commands
	
VNC
	vncviewer <colinux_ip>	# 800x600 tcp/5900
	vncviewer <colinux_ip>:1	# 1024 x 768
Cygwin
	XWin.exe :1 -screen 0 800x600 -query <colinux_ip>	# 800x600
	XWin.exe :2 -screen 0 1024x768 -query <colinux_ip> # 1024 x 768

NOTE: I don't cover making it secure in these instructions

If you haven't already got X and KDE installed run these commands
	apt-get install x-window-system-core
	apt-get install kdebase # run apt-get install kde for everything

edit /etc/X11/xdm/Xservers and comment out all the server entries 
coLinux will crash if it tries to launch a local X server and this stops that behaviour
	# :0 local /usr/X11R6/bin/X :0 vt9 -bpp 16
	# :1 local /usr/X11R6/bin/X :1 vt10 -bpp 8
	# :0 local /usr/X11R6/bin/X vt7 -dpi 100 -nolisten tcp
	# :0 local /usr/X11R6/bin/Xvnc -geometry 800x600 -depth 16 

In some of the other instructions it says to put the value "null" into /etc/X11/default-display-manager
however if you do the above step this is uneeded.
	
edit /etc/X11/xdm/Xaccess and uncomment the following line
	#*                                       #any host can get a login window

so it is like this
	*                                       #any host can get a login window

edit /etc/X11/xdm/xdm-config and set "DisplayManager.requestPort" to 177
	DisplayManager.requestPort:     177

edit /etc/inetd.conf and add the following (each entry must be on a single line)
	#:OTHER: Other services
	vnc-800x600     stream  tcp     nowait  nobody  /usr/sbin/tcpd  /usr/bin/Xvnc :1 -inetd -query localhost -geometry 800x600 -depth 24 -once
	# securitytypes=none this only needed on readhat systems
	vnc-1024x768    stream  tcp     nowait  nobody  /usr/sbin/tcpd  /usr/bin/Xvnc :2 -inetd -query localhost -geometry 1024x768 -depth 24 -once

edit /etc/services and add entrys for the new services
	# Local services
	vnc-800x600 5900/tcp
	vnc-1024x768 5901/tcp
	
Reboot coLinux

Errors:
	I got a few xdm respawning too fast errors ... not sure why but adding the `-config' argument seemed to help
