VncThumbnailViewer 1.4.2

VncThumbnailViewer is a free and open source Computer Lab monitoring software using VNC.
VncThumbnailViewer is a free and open source Computer Lab monitoring software using VNC.


1. Install and start a VNC Server on all lab machines. If you use UltraVnc or TightVnc on Windows it can install itself as a Service so it's always running. If you have Macs a VNC server is already installed.
2. Get a list of the IP addresses or hostnames of the computers.
3. Start VncThumbnailViewer on the teacher's computer.

■ I have bundled the jar file in Windows & Mac executables, so you should be able to just double-click it.
■ If you are familiar with Command Prompt, you can launch the viewer from a command line while specifying the hosts, ports, and passwords as such:

c: vncthumbnailviewer.exe HOST PORT 5900 PASSWORD pass HOST PORT 5900 PASSWORD pass

4. To add computers type in the IP address or Hostname, Port number, and vncserver Password in the dialog, then click "Add" for each computer. The viewers dynamically scale to fit in the window.
5. Double-clicking on a thumbnail will put that view in a new window with control of the mouse and keyboard.


Java Runtime Environment (JRE) 5 or later

What's New in This Release:

Two long-standing bugs have been fixed.
When double-clicking to focus on a specific VNC connection, the view is now full-sized.
Also, the thumbnails now present the full screen of the remote computers, without trimming the bottom portion of the screen.
