vino vs tightvnc server

Ubuntu uses Vino as default VNC server to share your existing desktop. With it, users can access Ubuntu remotely either in or out of local. Some SSH servers disable X by default and your admin may have to configure it. TightVNC puts a startup file in ~/.vnc/xstartup which might e.g. contain. dara.masashikuroki.xyz › forums › on-topic › suggestion-needed-on-vnc-ser.

Tigervnc seems to be a Fedora fork of tightvnc. All will work with other, but some improvements only kick in if both ends share the improvement. Xvnc in linux as installed with the tigervnc package is a little different animal. It is really a two-headed server, with an X server on one side and a vnc server on the other.

The X server is an entirely separate virtual display than the console. There is no physical monitor anywhere, but applications can be started which open that X server and display upon it. On the other side, VNC clients are able to view and control the applications which are displaying on the X server. Multiple users can have different desktop environments open, albeit using different network ports for each.

VNC ports normally start at , which vino attempts to use if it is enabled. So different remote users can use , , …. As a practical example, consider the Ubuntu box in my friends house. He has a box whose physical display is actually his giant television. He can control it with a keyboard and mouse in the living room, but for many administrative tasks that is inconvenient, and instead he uses a Windows box in a more comfortable location and opens a vnc client to the box.

Now with his windows mouse, screen and keyboard he can control the ubuntu box. He is using the vino server, and communicating on port When he moves the mouse on his windows box, the cursor moves on the television. Occasionally I attach to that box from my house through an ssh tunnel. If I try to connect to his vino server, the first issue is that I may be unsuccessful if he is already connected.

Or if I am connected, and he tries to, he will fail. Instead, I use an Xvnc connection. The geometry matches the screen at my house. Then I create an ssh tunnel connecting port x in my house to port on his box, where the new Xvnc environment is listening, and connect my local vnc client vinagre, or something else to localhost:x e. This can be achieved regardless of whether that system is running Linux, Windows or macOS.

In fact, there are even apps available for Android and iOS that will allow you to access your Ubuntu desktop from just about anywhere that a data signal is available. Remote desktop access can be useful in a number of scenarios. It enables you or another person, for example, to view and interact with your Ubuntu desktop environment from another computer system either on the same network or over the internet. This is useful if you need to work on your computer when you are away from your desk such as while traveling.

It is also useful in situations where a co-worker or IT support technician needs access to your desktop to resolve a problem. The Ubuntu remote desktop functionality is based on technology known as Virtual Network Computing VNC and in this and the next chapter we will cover the key aspects of configuring and using remote desktops within Ubuntu. Before starting it is important to understand that there are essentially two types of remote desktop access. The approach covered in this chapter is useful if you primarily use Ubuntu as a desktop operating system and require remote access to your usual desktop session.

When configured, you will take over your desktop session and view and control it remotely. This allows you to launch multiple desktop sessions in the background on the remote system and view and control those desktops over a network or internet connection. Preview Buy eBook Buy Print. In this chapter we will cover both secure and insecure remote desktop access methods. Assuming that you are accessing one system from another within the context of a secure internal network then it is generally safe to use the insecure access method.

If, on the other hand, you plan to access your desktop remotely over any kind of public network you must use the secure method of access to avoid your system and data being compromised. Remote desktop access on Ubuntu is provided by the Vino package. Begin by opening the settings app as shown in Figure Turn on the Sharing switch B and click on the Screen Sharing option C to display the dialog shown in Figure below:.

The Screen Sharing dialog provides the following configuration options to manage remote desktop access:. Although VNC viewer implementations are available for a wide range of operating systems, a tool such as the Remmina Desktop Client is recommended when connecting from Ubuntu or other Linux-based systems. Remmina is a user friendly tool with a graphical interface that supports the encryption used by Vino to ensure a secure remote connection.

After installing and launching Remmina, change the connection type menu marked A in Figure to VNC and enter into the address field B the IP address or hostname of the remote system to which you wish to connect:.

To establish the connection, tap the keyboard Enter key to begin the connection process. After a short delay, a second screen will appear requesting the desktop access password if one was entered when screen sharing was enabled earlier in the chapter :. The default settings for Remmina prioritize speed over image quality.

If you find that the quality of the desktop rendering is unacceptably poor, click on the settings button Figure in the left-hand toolbar within the remote viewer window and experiment with different settings until you find the ideal balance of performance and image quality:. It is important to understand that Vino, by default, requires that the remote connection be encrypted to ensure security. One of the reasons for using Remmina is that it fully supports the encryption used by Vino.

Unfortunately, these viewers do not support the encryption that Vino uses by default. Once installed, launch the viewer and enter the hostname or IP address of your remote Ubuntu system. On attempting to connect, a failure dialog will appear similar to the one shown in Figure To allow a connection to be established from a non-Linux system it is necessary to turn off the encryption requirement for the remote desktop connection.

To do this, open a terminal window on the Ubuntu system and run the following command using your account and without sudo privileges :. After disabling the Vino encryption requirement, attempt to connect from the RealVNC viewer once again. This time a warning will appear indicating that the connection is not encrypted:. Clicking the Continue button will dismiss the warning dialog and establish the remote connection.

Clearly, connecting to a remote VNC server using the steps in this section results in an insecure, unencrypted connection between the client and server. This means that the data transmitted during the remote session is vulnerable to interception. To establish a secure and encrypted connection from an Ubuntu system to a non-Linux client a few extra steps are necessary. The remote desktop connection from macOS and Windows in the previous section is considered to be insecure because no encryption is used.

This is acceptable when the remote connection does not extend outside of an internal network protected by a firewall. When a remote session is required over an internet connection, however, a more secure option is needed. This is achieved by tunneling the remote desktop through a secure shell SSH connection. To prove this, establish a connection to your remote Ubuntu system referencing port after the hostname or IP address, for example, and note that the connection is still established:.
