VNC Server
 "Virtual Network Computing (VNC) is a desktop protocol to remotely control another computer. It transmits the keyboard presses and mouse clicks from one computer to another relaying the screen updates back in the other direction, over a network"
We can configure VNC server instances for one or multiple users on a remote machine. We can use VNC to start graphical applications on boot and finally possible to enhance security by connecting to the server through encrypted SSH tunnels.
Security
The use of a vnc password provides security at the level of server access (it’s vulnerable to brute-force attacks though), but the whole VNC session is transmitted in the clear, without encryption. The easiest, but most effective, way to secure our connection to the VNC server is to connect through an encrypted SSH tunnel. This way the whole session will be encrypted.

SSh Server |
OpenSSH is a free SSH/SecSH protocol suite providing encryption for network services like remote login or remote file transfer.
OpenSSH is a FREE version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions. |

LTSP Server |
 LTSP is an add-on package for Linux that allows you to connect lots of low-powered thin client terminals to a Linux server. Applications typically run on the server and accept input and display their output on the thin client display. LTSP is available as a set of packages that can be installed on any Linux system.
The Linux Terminal Server Project adds thin-client support to Linux servers. LTSP is a flexible, cost effective solution that is empowering schools, businesses, and organizations all over the world to easily install and deploy desktop workstations. A growing number of Linux distributions include LTSP out-of-the-box.
Shiny new thin-clients and legacy PCs alike can be used to browse the Web, send e-mail, create documents, and run other desktop applications. LTSP not only improves Total Cost of Ownership (TCO), but more importantly, provides increased value over traditional computing solutions. LTSP workstations can run applications from Linux and Windows servers.
Linux thin-clients have proven to be extremely reliable because tampering and viruses are virtually non-existent. It's distributed under the GNU General Public License, meaning it's free and always will be.
You'll find that LTSP has comprehensive free and professional support, and it's developed by a very active global community. We invite you to participate too!
