Manual version (v1.0.14). Latest version is always on http://manual.lserveradmin.gr

Until now our lab was operating with local OS installations and local users without essential services. There are now over 10 services and our lab can use network users on Linux/Windows, with ability to boot from network, use site filters, control student PCs remotely via italc and many more.

This is a new situation with a lot more possibilities. The transition is smooth as the existing situation is not removed, and can be used temporarily if needed.

To achieve all of the above a new server PC was added and is hosting at least 3 virtual machines.

Server PC is running Proxmox Datacenter administration software based on Debian Linux.

Virtual machines are running on KVM virtualization technology.

The 3 virtual machines are the following:

• lserver : Server vm with all services, users, files and LServerAdmin administration software. It is running on Ubuntu LTS or Debian stable.
• ltsp : Ltsp server vm providing network boot to old machines and remote connection to Linux OS. It is running on Ubuntu LTS or Debian stable.
• win2016ts/win2019ts : Windows vm with remote access enabled so that we can connect remotely to Windows from old machines booted from network.

Ltsp and wints virtual machines are clients to lserver vm, where all users, files and services are located.

1. Our lab is almost ready and functional. Client PCs will need a simple Network boot configuration. After that we can connect to a client PC.
   • Connect to Client PC
2. We will connect to Server PC where the virtual machines are running and providing all the functionality.
   • Connect to Server PC
3. We will create a personal user account for administration for Linux and Windows OS
   • Create user - administrator
4. We will start LServerAdmin application to add or remove users and configure services
   • Start LServerAdmin application
5. We will connect to Windows, to their virtual machine, in graphical environment
   • Connect to Windows Virtual Machine
6. we will install software on Windows. This software will be available on all client PCs and all users.
   • Install Windows software
7. we will connect to Linux, to their virtual machine, in graphical environment
   • Connect to Linux Virtual Machine
8. we will install software on Linux. This software will be available on all client PCs and all users.
   • Install Linux software
9. We will see ways to access our files, distribute files to users and send files even from our home
   • Access to files
10. we will install a printer to be able to print from every client PC
    • Printers
11. Finally we will see how to start and stop the virtual machines and also the server PC
    • Boot - Shutdown
