These instructions explain how to view and control your Debian Linux machine’s graphical desktop from a remote location using TightVNC Viewer. TightVNC Viewer is free and can be installed on Windows, Mac OS X and Linux machines.
While tightvncserver can be installed on a Raspberry Pi running the Raspbian OS, we suggest that you use the RealVNC Server pre-installed on the latest versions of Raspbian.
Install tightvncserver on your Debian Linux machine to allow a network connection to its graphical desktop from a Windows, Mac, or Linux machine running TightVNC Viewer. Next, you’ll learn how to configure a remote.it Service that is compatible with tightvncserver so that you can easily connect to your machine's GUI from outside of your local network.
Devices: Any Debian Linux machine, including Raspberry Pi running the Raspbian operating system.
Clients: Windows, Mac OS/X or Linux running TightVNC Viewer.
In a terminal window on your Debian Family Linux machine, run the following commands:
sudo apt-get updatesudo apt-get install tightvncserver
Next, launch tightvncserver with the command:
tightvncserver will launch and ask you for a password, which you will use later for connection. You may also enter a different read-only password which will let you view the Linux machine's graphical desktop but not interact with it.
Next, confirm that tightvncserver is in fact running with the command:
ps ax | grep tightvnc
Next, check which port tightvncserver is listening on with the command:
sudo netstat -lpn | grep tcp
This command will show all currently active tcp listeners (servers) running on your Linux machine. Look for Xtightvnc in the list. There may be more than one entry. If so, choose the one with the lowest port number. In the example shown below, that is port 5901. Make note of this port number as you will need it in the next section where you will be adding the remote.it Service Attachment.
Run the remote.it configuration script:
At the Main Menu, install a new remote.it Service for VNC. If the actual port in use is not 5901, you will have the opportunity to set this during the installation.
When you’ve successfully installed tightvncserver and the remote.it VNC Service, the Main Menu will include an entry for Xtightvnc as shown above.
To connect, sign in to your remote.it account and locate the device in Devices view.
Click on the highlighted Device Name to open the Device Services dialog:
Now click on the highlighted Service Name to initiate the connection. In a few seconds you’ll see a dialog box similar to this:
Close the menu by clicking the “X” in the upper right corner. You may see a dialog asking whether you wish to allow Flash to run. You should allow Flash to run. Next, enter your VNC password and click on “Send” to continue.
Click on the link provided in the second option, which will open a Safari Window. Allow Screen Sharing to occur. Enter your VNC password when prompted.
Start the TightVNC viewer application, then copy and paste the address from the remot3.it dialog option #3 to the “Remote Host” field as shown below. Now, click on “Connect”.
When you see the VNC Authentication dialog, enter your VNC password and click on “OK” to continue.
Now you are connected remotely to your device's UI.
