Installing LTSP on Etch


using newer LTSP packages with Etch:


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:


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 dnsmasq nfs-kernel-server

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.


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.

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 (note: Debian LTSP still uses NFS by default).
