I know this is maybe too late to write an article for LMDE 3. But this is what I currently use at my office. I made this setup more than 2 years ago. It took me a week to figure out the problem I had regarding LTSP-Server installation and configuration. Until now I didn’t have time to document it. I followed the instructions mainly from here. At our office we have 5 thin clients and one LTSP-Server. The configuration looks like this:

Anyway, here are the steps that I did to install LTSP-Server at my office:
~$ sudo apt-get update
~$ sudo apt-get install ltsp-server-standalone dnsmasq epoptes epoptes-client ltsp-client network-manager-gnome dnsutils rsync
Add user to group “epoptes”, in this example “admin”:
~$ sudo usermod -G epoptes -a admin
Set the network like following screenshot:

My “/etc/ltsp/dhcp.conf” looks like following:
#
# Default LTSP dhcpd.conf config file.
#
authoritative;
subnet 192.168.68.0 netmask 255.255.255.0 {
range 192.168.68.20 192.168.68.250;
option domain-name "example.com";
option domain-name-servers 192.168.68.1;
option broadcast-address 192.168.68.255;
option routers 192.168.68.1;
next-server 192.168.68.1;
# get-lease-hostnames true;
option subnet-mask 255.255.255.0;
option root-path "/opt/ltsp/i386";
if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
filename "/ltsp/i386/pxelinux.0";
} else {
filename "/ltsp/i386/nbi.img";
}
}
Restart network-manager service:
~$ sudo systemctl restart network-manager.service
Find out kernel version and reconfigure the package:
~$ uname -r
4.9.0-8-amd64
~$ sudo dpkg-reconfigure linux-image-4.9.0-8-amd64
Update ltsp-image:
~$ sudo ltsp-update-image --cleanup /
Here are some pictures of the client during booting:






Okay, that’s it about my LMDE 3 LTSP-Server installation.
