Configuring VNC Security Type for Gnome 3.10 Sharing Desktop

Ubuntu 14

In this article, we will delve into the process of configuring the Virtual Network Computing (VNC) Security Type for Gnome 3.10 Sharing Desktop. This is a crucial task for system administrators who need to ensure secure and efficient remote access to their systems.

Quick Answer

To configure the VNC Security Type for Gnome 3.10 Sharing Desktop, you can use the dconf-editor tool to disable encryption by setting require-encryption to false. However, this is not recommended due to the security risks involved. It is advisable to use VNC viewers that support the default TLS Security Type or wait for updates from viewers like TightVNC. Prioritize the security of your systems when configuring remote access.

Understanding VNC and Gnome 3.10

VNC is a graphical desktop sharing system that allows you to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction, over a network.

Gnome 3.10, on the other hand, is a popular desktop environment for Linux based systems. It comes with a built-in VNC server for sharing the desktop, which is known as Vino.

The Importance of VNC Security Type

The VNC Security Type determines how the VNC server will authenticate and encrypt the connection. In Gnome 3.10, the default Security Type is TLS, which provides encryption for the connection. However, this Security Type is not supported by all VNC viewers. For example, TightVNC, a popular VNC viewer, does not support it.

Configuring VNC Security Type in Gnome 3.10

To configure the VNC Security Type in Gnome 3.10, we will use the dconf-editor tool.

Installing dconf-editor

If dconf-editor is not already installed on your system, you can install it using the following command:

sudo apt-get install dconf-editor

In this command, sudo allows you to run the command as the superuser, apt-get is the package handling utility in Debian-based systems, install tells it to install a package, and dconf-editor is the package we want to install.

Configuring the VNC Security Type

Once dconf-editor is installed, follow these steps:

  1. Open dconf-editor by typing dconf-editor in the terminal and pressing Enter.
  2. Navigate to org > gnome > desktop > remote-access.
  3. Look for the key require-encryption and set it to false. This disables encryption for the VNC connection.
  4. Save the changes and close dconf-editor.

By setting require-encryption to false, we are disabling encryption for the VNC connection. This allows us to use VNC viewers that do not support the default TLS Security Type.

A Word of Caution

Disabling encryption makes the VNC connection vulnerable to interception. All the data transmitted over the VNC connection, including passwords, will be visible in clear text on the network. Therefore, this solution should only be used in very safe networks where the connection is already encrypted on another layer.

Conclusion

While it is possible to configure the VNC server in Gnome 3.10 to use a different Security Type, it is not recommended due to the security risks involved. It is advisable to use alternative VNC viewers that support the default Security Type or wait for updates from TightVNC and other viewers. Always prioritize the security of your systems when configuring remote access.
