= Upstream Documentation =

for additional documentation about installing LTSP: 

http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtspDocumentationUpstream

= Installing LTSP on Lenny =

1. if you want a complete LTSP server with all the bells and whistles:

{{{  
apt-get install ltsp-server-standalone
}}}

if you want more fine-grained control, splitting some services off to separate servers, you can install "ltsp-server" instead, and manually install each of the other services.

(you can also get backported packages for lenny: [[LTSP/Howto/Lenny-With-Backports]] )

2. Build the LTSP client environment:

{{{
ltsp-build-client
}}}

If you're installing a different debian distribution than what's on the server, you will need to specify the --dist xxx commandline option. where xxx is your Debian distribution (e.g. lenny, etch). See /usr/share/debootstrap/scripts/.

ltsp-build-client will download a complete Debian filesystem into /opt/ltsp/i386 (or specify an alternate location with '--base') and install the ltsp-client and ldm packages (the LTSP Display Manager). Typically, you will need a desktop environment like gnome or xfce, or a window manager such as icewm installed on the server (NOT in the chroot).


If you change the IP data after you have done the initial setup and run `ltsp-update-sshkeys` on the server.

The files the client will boot are installed on the server into /var/lib/tftpboot. 

3. Configure /etc/dhcp3/dhcpd.conf and /etc/ltsp/dhcpd.conf:

Edit /etc/ltsp/dhcpd.conf to adapt to your network. See examples in /usr/share/doc/ltsp-server/examples/dhcpd.conf as a reference.

Include the LTSP dhcpd.conf at the bottom of /etc/dhcp3/dhcpd.conf

{{{
include "/etc/ltsp/dhcpd.conf";
}}}

Restart dhcp3-server:

{{{
invoke-rc.d dhcp3-server restart
}}}

Alternately, configure /etc/dnsmasq.conf:

See example in /usr/share/doc/ltsp-server/examples/dhcpd-dnsmasq and adapt to your network.
 
Restart dnsmasq:

{{{
invoke-rc.d dnsmasq restart
}}}

4. Configure /etc/exports:

{{{
/opt/ltsp *(ro,no_root_squash,async,no_subtree_check)
}}}

Restart nfs-kernel-server:

{{{
invoke-rc.d nfs-kernel-server restart
}}}

5. Start tftpd. By default, tftpd-hpa is started from inetd. you may need to restart inetd after installing tftpd-hpa.

{{{
invoke-rc.d openbsd-inetd restart
}}}

Alternately, edit /etc/default/tftpd-hpa to have tftpd-hpa start on it's own.

{{{
RUN_DAEMON="yes"
}}}

Then, comment the tftpd entry in /etc/inetd.conf.

{{{
#tftp           dgram   udp     wait    root  /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
}}}

restart inetd.

{{{
invoke-rc.d openbsd-inetd restart
}}}

and restart tftpd-hpa

{{{
invoke-rc.d tftpd-hpa restart
}}}

6. Boot a PXE or Etherboot capable machine and enjoy. note that some older versions of etherboot do not support ELF images, and may not work without additional configuration.

= Installing LTSP on Etch =

[[LTSP/Howto/Etch]]

using newer LTSP packages with Etch:

[[LTSP/Howto/Etch-With-Backports]]

== Customizations in the chroot ==

The 2 ltsp configuration files inside the client are /opt/ltsp/i386/etc/lts.conf and /opt/ltsp/i386/etc/default/ltsp-client-setup.  See the examples in /opt/ltsp/i386/usr/share/doc/ltsp-client*.   Also see the Edubuntu wiki http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/customizing-thin-client.html (note: Debian LTSP still uses NFS by default).
