LTSP Server
apt-get install ltsp-server-standalone (5.3.7)
cp -R /usr/share/ltsp/plugins/ltsp-build-client/Ubuntu /usr/share/ltsp/plugins/ltsp-build-client/LinuxMint
ln -s /usr/share/debootstrap/scripts/gutsy /usr/share/debootstrap/scripts/maya
sed -i ‘s/DIST=${DIST:-“$(lsb_release -s -c)”}/DIST=${DIST:-“precise”}/’ “/usr/share/ltsp/plugins/ltsp-build-client/LinuxMint/000-basic-configuration”
ln -s /usr/share/ltsp/plugins/ltsp-build-client/Debian-functions /usr/share/ltsp/plugins/ltsp-build-client/LinuxMint-functions
ltsp-build-client –arch i386

/etc/ltsp/dhcpd.conf – unverändert

apt-get remove network-manager

/etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
address 192.168.0.1
netmask 255.255.255.0

service networking restart
service isc-dhcp-server restart

/var/lib/tftpboot/ltsp/i386/lts.conf :

[Default]
LDM_GUESTLOGIN=True
#LDM_DIRECTX=True
LDM_PASSWORD=secret

#[ltsp20]

http://manpages.ubuntu.com/manpages/precise/man5/lts.conf.5.html

nützlich für LDM_AUTOLOGIN : ltsp-shutdown.desktop

LDM_GUESTLOGIN ähnlich ist wie LDM_AUTOLOGIN aber mit der zusätzlichen Möglichkeit sich mit seinem eingnem Namen anzumelden.
Default username ist der Name des Terminals (ltsp20,ltsp21, …)

/home/ltsp20 usw. werde nicht automatisch aufgeräumt.
Eine Lösung dafür:
[Ltsp-discuss] Guest sessions

Create /opt/ltsp/i386/usr/share/ldm/rc.d/S00-guest-sessions, with the
following contents:

case “$LDM_USERNAME” in
guest*)
ssh -S “$LDM_SOCKET” “$LDM_SERVER” ‘cd; rm -rf .* *; rsync -a /etc/skel/ .’
;;
esac

Save and run `sudo ltsp-update-image`, if you’re using NBD.

That’s it, now all user accounts where the username starts with
“guest*”, will have their documents and settings erased on login.

alkisg: Although that rm -rf should really be find . -delete

adduser ltsp20
adduser ltsp21
… (Passwort: secret)
