Transfer a copy of the script to your local machine by, for example, running the command scp. The point now is to run the vnccli script on your "local" machine (your Linux or Mac laptop, for example). If still no joy please contact the helpdesk. ![]() If this doesn't produce a second desktop in a window as just described, please enter: rm ~/.vnc/xstartup and try again. This second instance is running on the remote host .uk. If all is well, a window will appear on the console desktop which shows a second instance of your desktop. the configuration on the departmental networked Linux desktops) is intact (and assuming that you are physically present in the department) login at the console of a networked desktop, run a terminal and at the shell prompt enter: /alt/applic/vnc/vnccli. To check that the server configuration (i.e. Please re-read the comments at the beginning of the vnccli script (see below) and contact the helpdesk if stuck. ![]() #Tunnel pi vnc through ssh install#If this produces something like "vncviewer: command not found" then either you have yet to install a vncviewer OR (likely if you are using a Mac) you have neglected to make the vncviewer available in your PATH. To find out (once you have installed a VNC viewer of course) run: vncviewer -version. It is sometimes useful to know the version of VNC you are running. Linux computers may well have a vncviewer installed already, if not we advise installing either TigerVNC or RealVNC #Tunnel pi vnc through ssh how to#Please see the comments at the beginning of the vnccli script (see below) for advice on how to install this. #Tunnel pi vnc through ssh mac os x#Mac OS X computers will have ssh installed already but will not have a vncviewer program: we advise installing TigerVNC. You will need the following software installed on the local Linux/Mac computer you are going to try this remote access method from: ssh, vncviewer. #Tunnel pi vnc through ssh manual#If it fails, you might want to attempt the second, manual set up method. The first is recommended as it uses a shell script which sets up the ssh tunnel for you. This can be achieved by either of the two methods described below. At the time I set it up my router only had support for tap type connections but the Android client only supports tun type connections so I had to set up my own server.If you want a full graphical desktop login and/or if you have already tried ssh -X and it is "slow" From a Linux (or Mac) computer to one of our Linux computers using an ssh tunnel and VNC Setting it up and configuring it on the clients is a little bit awkward but once it is set up it works well and supported on all the platforms I have (iOS, Android, Windows, Linux, OSX).Ĭomputer security is all about accepting risk and in this case I’m willing to accept the risk of having the open port on my firewall with this mitigation in place.Ī lot of people have routers that support OpenSSH or have installed a third party firmware like DD-WRT or Tomato so that might be a route for you. I followed the tutorial here to set it up. That mitigates the fact that the port is open on the Internet. However, I have it configured so each device that connects has its own certificate and it only accepts connects from clients with a known cert. ![]() I didn’t want to have to rely on a third party so I did indeed open a port for OpenVPN to accept the incoming connections. There are similar services like TeamViewer which might work as well. I know there is more than one service that will let you do this but I’ve only had experience with LogMeIn’s Hamachi which worked very well but at the time didn’t have a free Android client so I don’t use it anymore. #Tunnel pi vnc through ssh cracker#Then it requires a cracker to both discover your opened port and have possession of your certificate.įinally, if you still want to avoid opening a port, you can set up a VPN connection. A stronger protection is to configure your ssh so it only allows logons from computers that present the right certificate. One is to use a non-standard port, though that is pretty weak protection. There are ways to mitigate the risk created by opening a port to the internet for SSH. Though I’m just a user so who knows what the developers think. There are dozens of other ways to do this outside of my. I 'm not sure they would want to spend the time to implement or the computer resources necessary to support this for all their users. But I still maintain that this is outside the scope of what my. would do. True, if this were implemented to tunnel the VNC traffic through the encrypted my. traffic it would indeed be secure.
