Desktop Host (X client)

http://tinyurl.com/8z4z8/Screenshot-Greeter.png

This system provides xdm, gdm, or kdm for remote sessions. This is the system that provides the desktop, applications, quasi-local device access, web access, DNS, and a few other things. application access and such to the clients. Most of the problems that occur on this machine will be due to buggy desktop apps or user error.

If you don't have a desktop, I suggest Gnome: GNOME for the End-User

Authentication

This should break off into it's own HOWTO Authentication Models, but it's fine here for now, I guess

UNIX

lucky you, this is done automatically!

/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow

Desktop Manager

Maybe instead of staring at the nice X screen with no login you'd like LTSP to work like you'd expect? Yeah... here we go

XDM/GDM

Code: Setup XDM
 vim /etc/rc.conf
 emerge gdm
 vim /etc/X11/gdm/gdm.conf
 rc-update add xdm default
 /etc/init.d/xdm start
File: /etc/rc.conf
 DISPLAYMANAGER="gdm"
 XSESSION="Gnome"
File: /etc/X11/gdm/gdm.conf
 [xdmcp]
 Enable=True

When you start up GDM there should be a setup button which allows you to configure some of these options with a slightly more user-friendly GUI. If you are already logged in as a normal user who is in the wheel group, you can pull up gdmsetup like so:

Code: gdmsetup
 xhost +
 DISPLAY=":0.0" sudo gdmsetup

HELP!!!

I believe that there is some way to have a host-specific script run at logon - or pass the hostname to a script at logon - something like that. How do we make this happen? It will be necessary to do so for clean user mounts of local devices!!!

xdm/Xsetup 	 	gdm/Init/Default (*)

KDM

Code: Setup KDM
 vim /etc/rc.conf
 emerge kdm
 vim /usr/kde/3.x/share/config/kdm/kdmrc
 rc-update add xdm default
 /etc/init.d/xdm start
File: /etc/rc.conf
 DISPLAYMANAGER="kdm"
 XSESSION="kde-3.x"
File: /usr/kde/3.x/share/config/kdm/kdmrc
 [Xdmcp]
 Enable=True

Please substitute the kde-3.x above with your current KDE version string (e.g. kde-3.4).

If you're seeing some error messages like "xdmcp unwilling" on the client console, double check your /usr/kde/3.x/share/config/kdm/Xaccess file. The default configuration should work, but may have to enable the client hosts there. You can use * as a host name to temporary allow all hosts for diagnostic purposes.

TIP: Linux Windows98 Terminals

I read an article on how to serve Win9x images instead of a linux kernel, but I can't find it.... it exists...

Order of Operations

In theory, you could stop right here and have a decent LTSP setup. Experience has shown, however, that you are likely to need local disk access, special monitor configurations, local applications, scripts, or other special needs which may be address in the next section.
