Click Next to continue. The next step of the installation process asks whether it should create program shortcuts in the start menu. We recommend that you leave all settings here at their defaults. The Additional Tasks options screen allows you to answer some important questions with regards to how VNC will function. You should choose whether or not you want these shortcuts. Running VNC as a system service will enable you to log into Windows after a reboot has occurred.
If you choose not to run the VNC service automatically this will provide an extra level of security as you control when people can access the system with a higher level of control. However running VNC manually will mean that you cannot access a computer that is not already logged in.
This allows you to connect to the Host system as soon as setup has completed. VNC Server will now be installed onto your computer. It may take a couple of minutes to complete. Once completed the Readme file for VNC is displayed.
This contains last minute information about VNC as well as copyright and support information. Click Next to proceed. This behaviour is expected. If you specified in during the setup to start the VNC System Service you will be presented with the above dialogue box. If you didn't you will see this box the first time you launch the VNC Server program from the shortcuts in the Start Menu. The Error is stating that no password has been issued to access the VNC workstation.
You must specify a password to connect to a VNC Server. You must now type a password in the password box. This password will protect your PC from the outside world. As such it should not be a familiar password, obvious for someone to guess and you should not write it down. If someone is able to guess the password then they will have full, anonymous access to your PC. The Java viewer allows you to access your PC remotely using a web browser.
This functionality is not available to Handheld PC users and will not be covered in this article. For security we recommend that you disable it. It allows you to automatically force the remote workstation to lock or log-out when the VNC session is terminated. For example if you only want people to be able to observe the remote workstation then you can disable input from the remote system.
You can also prevent input from the local machine if you don't wish people physically at the workstation to use the PC while you are connected. If you have multiple SSH servers sitting behind a single NAT device, then you can access each of them from outside of your network by running each SSH server on its own unique non-standard port. Install RealVNC 4. By default, VNC listens for incoming connections on port It also listens on port for Java-based users, which can be accessed by clients from a web browser.
In this example, I have set up the VNC server to run on port For the rest of the settings, the defaults should suffice. You should now see a window showing the remote computer. You can also make a shortcut for this connection. Now that you have 1 an SSH server running on a unique non-standard port and 2 a VNC server running on a unique port, you can access your VNC server securely from a remote computer.
If your ISP does not provide you with a fixed static IP address, you can still access your network, but one more step will be required. Whenever your IP address changes, the new information is communicated to the dyndns. In this manner, you can always access your remote computer by domain name remotecomptuer.
This example assumes the the public IP address of the remote network is Note that we have set up the SSH server to run on non-standard port port 22 is the default and that VNC is running on port is the default. One ssh client is the one included with Cygwin. From the Cygwin command line, you would enter the following command to ssh to your remote computer on port and establish a tunnel on port for VNC traffic:.
As before, you can create a shortcut to your secure VNC session. By the way ssh do you have to fix the SSH session timeout or VNCing will have periodic traffic to keep ssh alive without timeout. I wonder if I keep the vnc session idle for sometime would the ssh timeout and kill my vnc client??? Please comment. Nevermind i fixed the problem. I specified the public ip address in the tunnel setting of putty instead of the LAN ip. I set up Cygwin on my Windows 7 64 bit laptop on home.
I get a window that says status: connection established then about 10 seconds later another windows pops up and says connection closed. Any ideas? FYI: I tried this while I was on the same network at home from a separate computer and it worked.
