vnc server port number linux

vncserver -list only looks at files in ~/.vnc/. There should be a file in your ~/.vnc/ directory ending VNC by default uses TCP port +N,[5][6] where N is the display number (usually:0 for a physical display). Several implementations also start. The default port of VNC server is To reach the port through which a remote desktop will be accessible, sum the default port and the user's assigned. TEAMVIEWER PORTABLE FOR MAC

You can install the DE of your choice by running the appropriate commands below. For the purpose of this article, we will install Ubuntu Gnome Official flavor. Now start the VNC server by running the vncserver command as a normal user. Then set a view-only password if you wish, as follows. So, stop the VNC server using the following command, in order to perform some configurations. To configure GNOME or whatever desktop you have installed, create a file called xstartup under the configurations directory using your favorite text editor.

Add the following lines in the file. These commands will be automatically executed whenever you start or restart the TigerVNC server. Note that the commands may vary depending on the DE you installed. Next, start the VNC server by running the following command as a normal user. Set your own values for the display geometry.

In addition, use the -localhost flag to allow connections from the localhost only and by analogy, only from users authenticated on the server. In this case, the :1 means that the VNC server will run on display port number Once the VNC server has started, check the port it is running on with the netstat command. In this section, we will show how to connect to the VNC server, but before we go into that, you need to know that by default VNC is not secure by default it is not an encrypted protocol and can be subject to packet sniffing.

This problem can be fixed by creating a tunnel from the client to server connection through SSH. Using SSH tunneling , you can securely forward traffic from your local machine on port to the VNC server on the same port. Next install vncviewer client such as TigerVNC Viewer as follow s you can install any other client of your choice. Once the installation is complete, run your VNC client, specify the address localhost to connect to display 1 as follows.

Alternatively, open it from the system menu, enter the address above and then click Connect. You will be prompted to enter the VNC login password created earlier on, enter it and click OK to proceed. If the password is correct, you will land in the login interface of your desktop.

Enter your password to access the desktop. This is because it is designed to use specific security schemes other than SSH tunneling when attempting to authenticate with the server. However, the connection is secure once you have enabled SSH tunneling. In order to manage the VNC server under systemd i. Next, reload the systemd manager configuration to read the newly created a unit file, as follows.

Then start the VNC service, enable it to auto-start at system boot and check its status as shown. I advise against downloading the full Server and Viewer product for Windows for the scenario described here, because you do not need the VNC Server on your Windows system, and if it is running its use of network port may cause an inadvertent clash with your use of SSH tunnels. There's an alternative of TightVNC , not documented here.

You could reasonably put each of these commands into scripts to save typing in the future. The via option causes vncviewer to use ssh internally to tunnel the VNC session to the remote server, but you don't need to know the details of that see man vncviewer if you want. Observe that the internal ssh does not need the - X or - Y option, explicitly or defaulted, as X protocol is not used between your desktop and the remote server for the purposes of the VNC session.
