Since we are changing the configuration of the VNC server, we first need to stop the VNC server instance running on port 5901 using the following command: You can run multiple instances of VNC on other display ports, including : 2,: 3, etc. This port is called the display port and is considered by VNC as : 1. When VNC is initially configured, a default server instance is started on port 5901. The startup script was created when starting vncserver in the previous step, however we will create our own script to start the Gnome desktop. These commands are located in the xstartup configuration file in the. In particular, VNC needs to know which graphical desktop to connect to.
The VNC server must know what commands to execute at startup. Starting applications specified in /home/exsentis/.vnc/xstartup Log file is /home/exsentis/.vnc/your_hostname:1.log If you cannot access VNC, you may need to start the server on the remote instance:Xauth: file /home/sammy/.Xauthority does not existĬreating default startup script /home/exsentis/.vnc/xstartup
If you do not remember the password, use 'vncpasswd' on the remote instance to reset it. On the local machine, start your vnc client, connect to localhost:5902, and enter your VNC password. If you don't have a VNC client installed, install realvnc. When finished, exit the VNC client first, then exit ssh. Use the command 'vncpasswd' on the remote instance to reset it. On the local machine, start the VNC client, set its account to be ubuntu, connect to localhost:5902, and enter your VNC password. Type source port: ‘5902’, and destination: ‘localhost:5902’. On the putty-tunnel page, enter your instance IP address. Ssh into the remote instance using the ubuntu account. If no VNC client is installed, install realvnc client. When finished, exit ‘Screen Sharing’ first, then exit ssh. If VNC is not working, try the VNC client installation ( ). If there is connection but the display is all white, try checking ‘open in 32-bit mode’ of ‘Screen Sharing’. Vncserver :2 -depth 16 -geometry 1280x800 If you cannot access VNC, you may need to start the server on the remote instance: Use command 'vncpasswd' on the remote instance to reset it). On the local machine, use 'Screen Sharing' (From Finder, go to /System/Library/CoreServices directory, and double click “Screen Sharing.app”), connecting to and enter your VNC password. Ssh -L 5902:localhost:5902 -l ubuntu instance-ip-addressīefore connecting to VNC on the instance for the first time, change your VNC password by running: Ssh into the remote instance using the ubuntu account:
