We want to assist you in the most secure way.

As we want to minimize the risk of compromising sensitive data and passwords we use Free Software based on Open Standards. This is why we use Virtual Network Computing (VNC) as graphical desktop sharing system.

TeamViewer is a popular and easy to use desktop sharing program, but is proprietary software, for which we cannot be sure that remote access to your or our desktop is secure.

Although VNC passwords are sent DES-encrypted over the net, the rest of the traffic is sent as is, unencrypted. So using VNC over the Internet can be a security risk.

As long as VNC has no built-in encryption, we recommend installing an SSH server, and using SSH tunneling for all VNC connections.

When you want us to access your desktop . . .

Install a VNC server on your desktop computer.


Mac OS X

VNC Server is built-in software. Configure via System Preferences → Sharing → Screen Sharing


X11VNC Server 1)

sudo apt-get install x11vnc
  • Select “Accept Connections”
  • Select “Ask for Confirmation”
  • Set a hard-to-guess Password.
  • Optionally select “All Clients ViewOnly”

Create a port forward in your router to the VNC Server port 5900.

Hand us the public internet URL of your VNC Server and the password for the remote session.

When you want to access one of our demo desktops . . .

Install a VNC viewer on your desktop computer.


Mac OS X

Use this URL in Safari Web Browser:


Or use VNC viewer from http://tigervnc.org.

Debian / Ubuntu

sudo apt install remmina remmina-plugin-vnc

We will hand you the public internet URL of our VNC Server and the password for the remote session.

Do not use default VNC server vino in Ubuntu to share your existing desktop with other users, since this will give “Unknown authType 18” on all VNC Viewers, except Vinagre. Uninstall vino before installing X11VNC Server.
