If you wish to make your firewall rules more strict or allow range of ports for multiple VNC sessions visit our How to Open/Allow incoming firewall port guide for more information. In case you have the UFW firewall enabled, open the port 5901 for incoming connections or see below how to tunnel the VNC connections via the SSH protocol: $ sudo ufw allow from any to any port 5901 proto tcp

State Recv-Q Send-Q Local Address:Port Peer Address:Portįor example, I am using TightVNCViewer on Windows, thus I should enter xx.xx.xx.xx:5901 to connect to the vnc server. Your Ubuntu system should now be listening on the port 5901 for incoming VNC connections: $ ss -ltn The VNC server will open a new port for every new VNC desktop you create. Log file is /home/linuxconfig/.vnc/ubuntu:1.log Starting applications specified in /home/linuxconfig/.vnc/xstartup New 'ubuntu:1 (linuxconfig)' desktop is ubuntu:1

For this simply run the vncserver command from your home directory: $ vnc4server Lastly, make the ~/.vnc/xstartup file executable: $ chmod +x ~/.vnc/xstartupĪt this stage we are ready to start the VNC server. Insert the the following content and save: #!/bin/bash Next, create the ~/.vnc/xstartup file to start the Xfce4 desktop: $ mkdir ~/.vnc (vncpasswd command already create this folder in my case) This will also create a folder ~/.vnc and put a file 'passwd' inside it. Remember this as later you need it when you try to connect to this server from your vnc viewer. It will ask you set up a password for desktop access. Once the VNC server is installed we can begin the configuration by setting up a user password to be used by a VNC client when creating a remote connection: $ vncpasswd Let's start by the installation of the VNC server and the Xfce desktop manager core files: $ sudo apt install vnc4server xfce4 xfce4-goodies I found some difference from my machine and have marked it below.
