How to secure VNC remote access with two-factor authentication

Filed under
HowTos

VNC is the most popular remote access solution today. However, it was developed to provide remote access, not to provide secure remote access. Administrators have to add security to VNC by tunneling it through an encrpyted channel such as SSH and adding a layer of authentication. In this article, we will show you how to combine the NoMachine NX server to encrpyt VNC and remote X session combined with two-factor authentication from WiKID Systems to create a secure, fast remote access solution.

  • Device Tailored Compositors with Qt Wayland at CLAAS E-Systems
    Have you heard about software in cars that run on embedded devices? Do you think that creating such software might be challenging? Well, welcome to a complete new world of complexity, welcome to the world of agriculture machines! For many years, automatic steering (on fields), terminals to control the complex mechanical operations of a self-driving 16 ton combine harvester on a soft ground, and self-optimization systems to optimize any tiny bit of your harvester, are key demands from customers. I, myself, am working at CLAAS E-Systems, the electronics and software department within the CLAAS group. Our group is well known for being among the leading manufacturers for combine harvesters, tractors and forage harvesters.
