VNC was originally developed by the RealVNC team while at Olivetti Research Ltd / AT&T. By running vncviewer without specifying -listen or a host to connect to. where host is the host where the listening viewer is running. Note the netstat output, now in a working condition: netstat -ano | grep 5900 The actual display or port number you specify in the VNC client must be the. Note that, as long as the port 5901 TCP is occupied, X11VNC uses the 5900 TCP (aka :0 port): The VNC desktop is: Frambuesio:0 and now the X11vnc program makes display :1 available. In the Name field enter some title for this connection. In the next window enter the IP address in the VNC Server field and, after a colon, port. Then create a new connection via File -> New connection menu. on another terminal: sudo x11vnc -display :1 -passwd anypassword -auth guess -forever If you have installed RealVNC, then open the VNC Viewer application. My workaround for now consists on using X11vnc to serve the display on another port: vncserver -name Frambuesio -geometry 1280x1024 -depth 16 I would prefer some GNU's more open policies for my VNC, as long as it could be used in an enterprise production environment. The listening viewer will remain in this dormant state until a remote. But the RealVNC program installs a ton of extra packages and is not open source, even when it is free for educative purposes. ii Select the RealVNC entry, then VNC Viewer 4 and finally select Run VNC Viewer. I have read the official Raspberry papers, consisting on installing the realvnc-vnc-server package. Starting applications specified in /home/luis/.vnc/xstartup VNC on computer C is listening on port 5900. New 'Zarzaparrillo' desktop is Zarzaparrillo:1 remote port: Port on which the remote computer is listening for incoming connection. If I try from Ubuntu 16.04.3 on another Raspberry Pi everything goes all right (note the different netstat results): vncserver -name Zarzaparrillo -geometry 1280x1024 -depth 16 Nmap done: 1 IP address (1 host up) scanned in 0.67 seconds MAC Address: B8:27:EB:7D:7C:B0 (Raspberry Pi Foundation) Tcp6 0 0 ::1:5901 :::* LISTEN off (0.00/0/0)īut my VNC Viewer (from RealVNC on a remote Windows machine) receives the message " Connection refused" when trying to connect, and the port doesn't seem to be listening: sudo nmap Frambuesio-p 5900,5901,5902 Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/luis/.vnc/passwd :1 to connect to the VNC netstat -ano | grep "5901" From vncserver command line help: -localhost yesno Only accept VNC connections from localhost This should solve your problem: vncserver -localhost no Interpreting the same last example in the original question, note the 0.0.0. Log file is /home/luis/.vnc/Frambuesio:1.log Starting applications specified in /etc/X11/Xvnc-session New 'Frambuesio' desktop at :1 on machine Frambuesio I have installed TightVNCServer on Raspbian (the September 2.017 version) for my Raspberry Pi 2 B+ : vncserver -name Frambuesio -geometry 1280x1024 -depth 16
